Abstract
In this seventh instalment of the TED (TiredโExerciseโDiet) Series, we explore the neuroscience of physical exercise and its central role in emotional regulation, cognitive function, and mental health.
Within the NeuroAffective-CBTยฎ (NA-CBT) framework, exercise represents the โEโ in TED – the second pillar of biological stability upon which self-regulation and psychological flexibility depend.
This chapter presents both theoretical foundations and practical guidance for integrating physical and relaxation training, circadian rhythm alignment, and behavioural activation into therapeutic practice.
Drawing from sports science, neuroendocrinology, and behavioural neuroscience, it outlines evidence-based applications for enhancing biological resilience and emotional regulation.
Ultimately, this instalment concludes the biological foundations of the TED model, offering clinicians a cohesive framework for embedding exercise-related interventions into the NeuroAffective-CBTยฎ therapeutic process.
A glossary of key terms is provided at the end of the article to support comprehension and deepen the readerโs learning experience.
Introducing TED within the NA-CBTยฎ Framework
The TED model (TiredโExerciseโDiet) integrates neuroscience, psychophysiology, and behavioural science into a cohesive structure for promoting emotional regulation and biological stability. Within NeuroAffective-CBTยฎ, TED forms the foundation of the BodyโBrainโAffect Triangle, a conceptual model linking physiology, cognition, and emotion (Mirea, 2023; Mirea, 2025).
Earlier instalments in this series examined six primary regulators of mood and cognition:
โข Creatine (Part I)
โข Insulin Resistance (Part II)
โข Omega-3 Fatty Acids (Part III)
โข Magnesium (Part IV)
โข Vitamin C (Part V)
โข Sleep (Part VI) – the neurobiology of fatigue and recovery within the Tired pillar
This chapter extends the model to the โExerciseโ component, the dynamic driver of both physical and psychological resilience, while revisiting Tired through the lens of sleep neuroscience and affect regulation to underscore their interdependence within NeuroAffective-CBTยฎ.
The โEโ โ Exercise as the Biological Catalyst
โEโ stands for Exercise, a symbol of physical strengthening and a reminder that movement is integral to human adaptability and emotional balance. Evidence consistently demonstrates that regular physical activity not only boosts immunity but also regulates hormones, enhances protein synthesis (similarly to sleep), and supports the management and prevention of a wide range of mental health conditions (Nieman, 2018; Mahindru, 2023; Mennitti et al., 2024; Strasser, 2015; Deslandes, 2014).
The forthcoming section, โDโ, will explore the relationship between muscle size and glucose regulation, providing further evidence that muscle-strengthening activity exerts measurable effects on both body and mind. This connection is deeply evolutionary. Humans were not designed for sedentary living or sugar-rich diets but for creative movement, exploration, and endurance. It was this unique blend of curiosity, resilience, and physical vitality that allowed humans to survive, innovate, and thrive.
TED Takeaway:
โข Movement restores synchrony between body, brain, and affect.
โข Exercise is not ancillary to therapy; it is a biological stabiliser and an emotional educator.
Exercise, Adaptation, and Individualisation
To sustain motivation and promote long-term adherence, physical strengthening programmes should always be individualised, taking into account differences in age, sex, current physical condition, as well as personal preferences and cultural values.
Research consistently shows that when physical activity is enjoyable and personally meaningful, when it connects to an individualโs goals, such as improved strength, confidence, or self-image, both physical and psychological outcomes are significantly enhanced. A foundational paper in Self-Determination Theory by Deci and Ryan (2000) demonstrated that intrinsic motivation – the sense of enjoyment, personal meaning, and autonomy, predicts adherence and well-being across multiple domains, including physical activity, while a comprehensive review by Teixeira et al. (2012) further confirmed that autonomous motivation and enjoyment are key predictors of both exercise adherence and psychological benefit.
Within the NeuroAffective-CBTยฎ framework, exercise recommendations integrate both muscle activation (tensing or strengthening) and muscle relaxation practices. What contracts must also release – this natural cycle of tension and relaxation supports recovery, balance, and emotional regulation.
This principle is exemplified in Progressive Muscle Relaxation (PMR), first introduced by Edmund Jacobson in the 1930s (Jacobson, 1938). PMR combines focused attention with abdominal breathing, guiding individuals through cycles of tensing and releasing specific muscle groups. Over time, this practice develops interoceptive awareness – the ability to sense and modulate bodily tension, recognise signs of stress, and release it through mindful breathing. More recent research shows that enhancing interoceptive awareness can also improve attentional control, focus, learning capacity, and ultimately cognitive flexibility, key components of adaptive emotional regulation and psychological resilience (Farb, Segal and Anderson, 2013; Schulz, 2016).
- Martial arts training supports individuals struggling with confidence, assertiveness, or low self-esteem, blending controlled power with discipline and focus.
- Team sports are often beneficial for those with social anxiety, providing gradual social exposure within structured, cooperative settings.
- Yoga: effective for stress regulation and interoceptive awareness, with added benefits for mobility and strength depending on style (e.g., Hatha/Iyengar for alignment and control; Vinyasa/Ashtanga for conditioning). Can be prescribed on its own or as an adjunct to any of the above. Consider trauma-sensitive formats when relevant; introduce load and range progressively, and use care with generalised hypermobility (prioritise stability and pain-free ranges).
- Culturally rooted movement practices, such as Capoeira in Brazil, Tai Chi in East Asia, or traditional dance forms found in many Indigenous and Mediterranean cultures, can serve as powerful, identity-affirming exercises. These activities not only promote physical health but also reinforce cultural belonging, foster feelings of acceptance, and build community connection. Such practices can be particularly beneficial for individuals experiencing social isolation or depression, as they combine movement, rhythm, and shared meaning โ all of which strengthen emotional resilience and a sense of self within a social context (Koch et al., 2019; Li et al., 2012).
- For clients with Body Dysmorphic Disorder (BDD), bodybuilding requires careful framing and monitoring; appearance-driven goals can reinforce maladaptive self-evaluation, whereas performance-based strength training may be safer.
Modern therapeutic approaches such as Grounding, Mindfulness-Based Stress Reduction (Kabat-Zinn, 2003), or Mindfulness-Based Cognitive Therapy (Segal, Williams, and Teasdale, 2002) share this same purpose: enhancing body awareness, recalibrating neurophysiological responses, and strengthening emotional self-regulation.
Ideally, when physical health permits, one should train daily, alternating between activation (strength or resistance training) and relaxation (PMR, Grounding or Mindfulness) to maintain both physical tone and emotional equilibrium.
TED Takeaway:
โข Pair strength with release (PMR/yoga/mindfulness) to preserve the physiological rhythm of activationโrecovery.
โข Practical cadence (health permitting): train most days, alternating activation (20โ40 min) and relaxation (10โ20 min) to maintain tone and equilibrium.
โข Enjoyment and meaning are not optional; they are mechanisms of adherence and benefit.
Condition-Specific Exercise: Matching Movement to Mind
Certain exercise modalities align particularly well with specific emotional or cognitive profiles, provided they are introduced with gradual exposure and incremental goals that promote both physical and psychological growth.
Therapeutic exercise selection should always remain person-centred, attuned to both psychological needs and affective drivers of behaviour, while respecting individual and cultural identity.
TED Takeaway:
โข Match the modality to the mechanism you want to train (confidence, social approach, cultural belonging, stress regulation).
โข Keep exposure graded and goals process-focused; adjust style and dose to the person.
NA-CBT Tools for Performance Priming
- Breathing, Attention & Arousal Regulation:
Your breathing pattern is one of the fastest ways to change how alert, focused, or calm your body feels, itโs a direct link between the body, brain, and emotions. In simple terms, how you breathe sends a signal to your nervous system about whether itโs time to perform or recover.
When you need to up-regulate, that is, increase alertness, focus, and readiness before a challenging effort, try short, sharp inhales or slightly constrained exhales.
This kind of breathing activates your bodyโs sympathetic nervous system (the โget up and goโ system), increasing blood flow, oxygen delivery, and mental sharpness.
For example:
โข Before a sprint, lift, or high-intensity set, take two or three quick inhales through the nose and one strong exhale through the mouth.
โข Youโll feel your heart rate rise and your focus sharpen, your body preparing to perform.
Then, between sets or after the workout, you want to down-regulate, to shift into recovery mode. This is when you lengthen your exhales or practise relaxation methods such as Progressive Muscle Relaxation (PMR) or breathing and stretching. Long, slow breaths stimulate the parasympathetic nervous system, your โrest and repairโ mode, lowering heart rate, easing muscle tension, and improving focus for the next round.
In essence, your breath acts like a volume dial for your nervous system:
โข Faster or shallower breathing turns up the system for performance.
โข Slower, deeper breathing turns it down for recovery and calm.
Learning to consciously move between these two physiological states – activation and recovery – strengthens both performance and resilience. These principles align closely with findings in applied sport psychology, where self-regulation of attention and arousal is central to maintaining consistent, high-level performance (Weinberg and Gould, 2019).
Over time, this skill becomes a cornerstone of self-regulation training within the NeuroAffective-CBTยฎ framework, linking movement, breath, and attention into one coherent system for emotional and physical balance.
2. High-Signal Tools: Music, Caffeine, and Nootropics
Tools such as caffeine, motivational music, or cognitive enhancers (nootropics) can provide a powerful mental and physical boost before exercise. However, the nervous system adapts quickly to these high-signal aids. When they are used in every session, their effects diminish over time, and motivation can begin to depend on them rather than arise naturally.
To prevent this tolerance effect, reserve high-signal tools for key or demanding training days rather than routine sessions. This aligns with the signal-to-noise principle in neuroscience: when stimulation (the signal) becomes constant, the brain starts to tune it out (increasing noise).
TED Takeaway: Using these tools strategically preserves their potency and supports the development of intrinsic focus and self-regulation. Typical caffeine guidance is around 1โ3 mg per kilogram of body weight, avoiding late-evening doses. Always consider potential interactions or contraindications (e.g., anxiety, hypertension, pregnancy, or psychotropic medication use).
3. Boundaries that Prime Intent and Focus
Setting a physical or mental threshold before training, such as drawing a line on the floor, standing at the gym door, or taking a moment before stepping onto a platform, can significantly improve performance. This small ritual tells the brain, “Iโm about to begin something important“.
Crossing that boundary only when mentally ready acts like a psychological switch, heightening attention, intention, and effort quality. It helps athletes transition from everyday distraction into a state of focused readiness, where the body and mind align for optimal performance.
In practice, this is less about superstition and more about neuro-behavioural priming, conditioning the brain to associate a specific action (crossing the line) with focus and engagement. Over time, this can strengthen self-regulation and consistency, even on low-motivation days.
TED Takeaway:
โข Faster, shallower breathing โ performance state.
โข Slower, longer-exhale breathing โ recovery state.
โข Save high-signal tools for important sessions to preserve their potency and your intrinsic drive.
โข A brief pre-set boundary ritual improves consistency and effort quality.
Body Temperature & Performance
The bodyโs ability to maintain an optimal temperature range influences far more than endurance โ it also affects motivation, muscle efficiency, and mental focus.
A lesser-known but fascinating fact is that glabrous skin – the hairless, thick skin found on the palms, soles, and parts of the face (such as the lips and nasal area) – plays a key role in thermoregulation. These regions are rich in arteriovenous anastomoses (AVAs), specialised blood vessels that allow rapid heat exchange. This is why the hands, feet, and face are particularly effective for cooling or warming the body.
This understanding may also shed light on certain ancestral behaviours, such as the instinctive human tendency to touch natural surfaces or another personโs skin to gauge warmth, comfort, or safety, an evolutionary remnant of how we once regulated both physical and emotional connection through touch.
Research shows that palmar cooling (cooling the hands between sets or during endurance exercise) can substantially increase work output in hot conditions, while reducing thermal fatigue and improving recovery (Grahn, Cao & Heller, 2005; Heller, 2010).
Interestingly, Dialectical Behaviour Therapy (DBT), a third-wave CBT approach developed by Marsha Linehan, also uses temperature-based interventions for emotional regulation. During states of high emotional arousal, clients are taught to cool the body rapidly using ice packs on the face or brief facial immersion in cold water. This activates the mammalian dive reflex, which lowers heart rate and stimulates the parasympathetic nervous system, producing a powerful calming effect (Linehan, 2014).
When the body overheats, muscles work less efficiently, excessive heat disrupts energy production. As temperature rises, the chemical reactions that generate energy through adenosine triphosphate (ATP) begin to falter. A key enzyme in this process, pyruvate kinase, which helps convert fuel into usable energy, slows down or even stops functioning properly. The result is simple: overheated muscles fatigue faster, lose power, and overall performance declines.
Conversely, controlled cooling helps sustain endurance and recovery by maintaining thermal balance. The palms, soles, and face act as natural radiators through their AVAs, enabling rapid heat dissipation and stabilising core temperature.
Simple practical methods include holding cool (not ice-cold) objects or briefly immersing the hands or feet in cool water between training bouts. This straightforward approach can lower perceived effort, extend training capacity, and accelerate post-exercise recovery.
These findings reinforce the importance of temperature regulation as part of recovery and emotional self-regulation within the TED framework.
TED Takeaway:
โข Gentle cooling after exercise helps the body shift more quickly into recovery mode by supporting the parasympathetic nervous system, which governs rest, repair, and relaxation.
โข Rinsing the hands, feet, or face with cool water after exercise stabilises heart rate and calms the body within 30โ60 minutes, improving recovery and emotional balance.
โข Excessive or immediate full-body cold exposure โ such as jumping straight into an ice bath โ can interfere with the bodyโs mTOR repair signalling, slowing muscle growth and adaptation.
โข In short: a little cooling helps the body recover faster, but too much too soon can blunt the benefits of training.
โข Safety note: Cold immersion should be avoided in cases of unmanaged cardiovascular disease, severe Raynaudโs, or neuropathy; seek medical guidance if unsure.
Cortisol isnโt the enemy: time it, donโt flatten it
Because cortisol often rises during stress or anxiety, itโs sometimes misunderstood as purely harmful. In reality, short-term cortisol spikes after training are vital, they mobilise fuel, drive adaptation, and signal recovery.
The goal is rhythmic spikes that return to baseline, not chronic elevation.
Blunting cortisol too early, through overuse of supplements, anti-inflammatories, or excessive carbohydrates, can impair muscle repair. Instead, allow cortisol to rise during exertion and fall gradually post-training. Strategically timed carbohydrate intake can facilitate this recovery phase by naturally lowering cortisol while replenishing glycogen stores and improving sleep quality.
Heart rate (HR) and heart rate variability (HRV) help monitor stressโrecovery balance. Low HRV or chronically elevated HR may signal overtraining, poor sleep, or psychological stress. Moderate, consistent exercise combined with rest, hydration, and mindfulness restores autonomic balance and resilience.
TED Takeaway:
โข Evening or post-training carbohydrates (prefer minimally processed, starchy sources) can assist cortisol down-shifting, support sleep, and replenish glycogen.
โข Avoid overuse of โcortisol blockersโ – heavy alcohol, or sedative strategies, as they can impair adaptation and sleep architecture.
Mirrors, Interoception, and Motor-learning
Technological aids such as mirrors or video feedback can be useful in the early stages of learning new movements. They help individuals understand form and alignment, but the ultimate goal is a felt sense of movement, awareness that comes from within, rather than dependence on external feedback.
Hypertrophy focus (muscle growth and strengthening): Using a mirror occasionally or posing between sets can improve body awareness and help engage the target muscles more effectively during training.
Speed or skill learning (e.g., Olympic lifts, sprints): Avoid mirrors, as they shift attention outward and reduce interoceptive awareness, the ability to sense and adjust body position and movement internally.
TED Takeaway:
โข Mirrors and video feedback can support early learning, but lasting skill comes from internal awareness.
โข Develop a felt sense of movement – coordination and control without reliance on external cues.
Train Recovery and Relaxation: The Pathway to Physiological Resilience
Like any other skill, the ability to switch off, relax, and recover can be trained. Recovery is not fixed, it can be strengthened over time. Just as you build muscle through progressive challenge, you can train your recovery systems by occasionally pushing slightly beyond what feels comfortable (in a safe and controlled way). Each small, well-managed challenge helps your body and mind learn to adapt to stress more effectively.
To build this kind of resilience, focus on the fundamentals:
- Keep your sleep regular. Get morning light to wake your system and dim evening light to prepare for rest.
- Eat well. Make sure youโre getting enough energy, protein, and hydration to help your body repair itself.
- Use temperature wisely. Short, gentle exposures to heat or cold (with enough rest between) train your body to adapt to different environments.
- Stay connected and mindful. Supportive relationships, journaling, mindfulness, or relaxation exercises such as Progressive Muscle Relaxation (PMR) all help keep your nervous system flexible and balanced.
This rhythmic cycle of effort and restoration forms the biological basis of resilience within the TED framework, teaching the body to recover as deliberately as it performs.
TED Takeaway:
โข Use graded, manageable challenges to expand capacity โ always with control and recovery.
โข In NeuroAffective-CBTยฎ, this reflects a core principle: gradual, intentional exposure to small challenges increases the ability to cope with stress while maintaining emotional balance and self-regulation.
Conclusion
Exercise is more than physical conditioning; it is a biological and emotional regulator – a living interface between movement, emotion, and cognition. Behavioural principles long recognised this: Lewinsohnโs model linked reduced engagement with loss of reinforcement; Behavioural Activation (Jacobson, Martell & Dimidjian, 2001) reinstated purposeful activity; Beckโs cognitive therapy integrated behavioural experiments, graded tasks and activity scheduling (Beck et al., 1979).
Within the NeuroAffective-CBTยฎ model, the โEโ in TED symbolises this central truth: emotional stability and cognitive clarity arise not in isolation, but through the synchrony of body and mind.
The TED framework demonstrates that emotional regulation is not achieved through thought alone, but through the rhythmic cooperation of the bodyโs systems, when we are tired, exercised, and nourished in balance. In essence, exercise functions both as a biological stabiliser and an emotional educator, a continuous dialogue between movement, mood, and meaning.
The TED model reminds us that resilience is not a fixed trait but a rhythm, cultivated through synchrony, when the body rests, moves, and restores itself in harmony.
In the forthcoming and final section, โDโ, we will complete the TED model by exploring Diet, the biochemical cornerstone of mental health, and its interdependent relationship with exercise, sleep, and emotional regulation.
Ten TED Takeaways: Physical Exercise and Mental Health
- Movement is Medicine. Exercise is a biological necessity that supports immunity, hormone balance, protein synthesis, and emotional regulation.
- Cortisol is adaptive, not destructive. It should rise during exertion and fall during recovery.
- Evolution Favouring Motion. Human physiology is designed for activity. Movement restores the natural synchrony between body, brain, and affect.
- Balance Between Tension and Release. Strength must coexist with recovery. PMR, yoga, and mindfulness sustain this physiological rhythm.
- Exercise as Emotional Education. Physical training teaches the bodyโmind connection, transforming tension into awareness and control.
- Personalised Movement and Training. Match the type or exercise modality to the person: martial arts for confidence, team sports for social anxiety; use caution with appearance-driven training in BDD.
- Embodied Self-Regulation. Within NeuroAffective-CBTยฎ, exercise is the โEโ, the biological catalyst linking movement with mood and self-regulation.
- Use โhigh-signalโ tools sparingly. Keep caffeine, music, and stimulants for key days to maintain their effect.
- Intentional boundaries prime the mind. Physical thresholds before training enhance focus and effort quality.
- Integration, Not Isolation. Emotional stability requires synergy between Tired, Exercise, and Diet – rest, movement, and nourishment.

Glossary and Key Terms:
Behavioural activation is a CBT approach that helps people improve their mood by reconnecting with meaningful, goal-directed activities, especially when they feel low or unmotivated. When someone is depressed or anxious, they often withdraw from daily life and lose motivation, which makes them feel even worse. Behavioural activation works by re-introducing positive routines, encouraging gradual re-engagement in small, rewarding, or purposeful actions such as exercise, social contact, or creative tasks. In the TED framework, behavioural activation supports both the โExerciseโ and โDietโ pillars by re-energising the body, increasing motivation, and helping to rebuild emotional stability through movement and engagement.
Circadian Rhythm
Your circadian rhythm is the bodyโs natural 24-hour internal clock that controls when you feel awake, sleepy, and even how your mood, hormones, and energy levels change throughout the day. Itโs regulated mainly by light and darkness, sunlight in the morning tells your brain itโs time to be alert, while darkness at night signals that itโs time to rest. Keeping this rhythm regular (for example, by getting morning light, avoiding late-night screens, and sleeping at consistent times) helps improve sleep quality, mood, focus, and recovery.
Cognitive Corollary
A related mental or thinking process that accompanies a physical or biological change. For example, a cooler body temperature can make effort feel easier, improving focus and learning.
Cortisol
A natural hormone released by the adrenal glands, often called the โstress hormone.โ It helps regulate metabolism, inflammation, and the bodyโs response to stress. Healthy cortisol levels rise in the morning to energise you and drop in the evening to help you rest.
HR (Heart Rate)
The number of times your heart beats per minute. Resting heart rate tends to be lower in fitter individuals and can rise with stress, dehydration, or illness.
HRV (Heart Rate Variability). A measure of the small variations in time between heartbeats. High HRV usually means your body can adapt well to stress; low HRV can indicate fatigue, overtraining, or poor recovery.
Hypertrophy Stimuli
Anything that triggers muscles to grow larger and stronger, such as resistance training, mechanical tension, or specific metabolic stress during exercise.
mTOR Repair Pathway
Short for โmechanistic Target of Rapamycinโ, mTOR is a key biological pathway that helps the body grow and repair cells, especially muscle tissue. After exercise, this pathway acts like a โconstruction managerโ, signalling the body to build new proteins, repair tiny muscle tears, and grow stronger tissue. If this process is interrupted for example, by too much cold exposure immediately after training, muscle recovery and growth can slow down.
Neuropathy
Damage or dysfunction of the nerves, often causing tingling, numbness, weakness, or pain, most commonly in the hands and feet. It can result from diabetes, injury, infections, or certain medications.
NSAIDs (Non-Steroidal Anti-Inflammatory Drugs)
A class of medications, such as ibuprofen, naproxen, and aspirin, used to reduce pain, inflammation, and fever. Overuse can sometimes irritate the stomach or affect kidney (renal) and liver (hepatic) function.
Protein synthesis – bodyโs process of building new proteins, which are essential for repairing tissues, producing hormones, and supporting growth and recovery, particularly after exercise. Itโs how your muscles rebuild and strengthen following physical activity, and it also plays a role in brain health, helping support learning, memory, and mood regulation. This process depends on good nutrition, regular exercise, and adequate sleep, all of which are central to the TED model.
In essence, protein synthesis is the bodyโs repair and renewal system, keeping both mind and body in balance.
Raynaudโs / Vascular Disorders / Neuropathy
Conditions that alter blood flow or nerve function – consider when prescribing temperature strategies. Raynaudโs is a condition where blood vessels in the fingers and toes become overly sensitive to cold or stress, causing them to temporarily narrow. This limits blood flow and can make the skin turn white or blue and feel numb or painful.
Renal / Hepatic
โRenalโ refers to the kidneys, which filter waste and maintain fluid balance. โHepaticโ refers to the liver, which processes nutrients, hormones, and drugs. Both organs are vital for detoxification and energy metabolism.
Tolerance – refers to the bodyโs process of adapting to a substance or stimulus over time, which makes its effects weaker or shorter-lasting.
For example, if someone regularly uses caffeine, certain medications, or motivational tools (like loud music or pre-workout stimulants), the body and brain gradually become less responsive to them. This means that more of the same stimulus is needed to achieve the same effect, or it stops working altogether.
In the context of the TED model, tolerance explains why โhigh-signalโ tools, such as caffeine, nootropics, or intense motivation strategies, should be used sparingly, to prevent over-reliance and maintain natural motivation and balance.
