Setting the stage
When we think about high performance — whether it’s training hard at the gym, grinding through long workdays, or bouncing back from an injury — most of us focus on the obvious stuff: the workouts and the rehab sessions.
But here’s the thing: what you do between those efforts matters just as much, if not more. Sleep, nutrition, and stress management are the behind-the-scenes forces that allow your body to adapt, repair, and come back stronger.
If these aren’t dialed in, it won’t matter how hard you train or how detailed your rehab plan is — your body simply won’t be able to recover or perform at its best.
🛌 Sleep: Your Body’s Built-In Recovery System
You don’t get stronger during a workout — you get stronger after it, while your body’s repairing itself. And that repair happens most powerfully during deep, restful sleep.
While you sleep, your body:
- Releases melatonin to reduce oxidative stress and calm inflammation
- Surges growth hormone and androgens to build and repair muscle and tissue
- Resets your immune, endocrine, and nervous systems
- Consolidates learning and memory — crucial when you’re relearning movement patterns during rehab
When you skimp on sleep, the opposite happens: growth hormone drops, cortisol (your stress hormone) rises, pain sensitivity increases, and tissue repair slows. That means slower recovery, lower performance, and even higher risk of injury.
✅ Takeaway: Sleep isn’t just downtime — it’s part of your training. Protect it like you protect your workout time. Aim for 7–9 hours a night and build simple sleep habits like:
- Keeping a consistent bedtime and wake time
- Making your bedroom dark, cool, and comfortable
- Avoiding screens for an hour before bed
- Keeping phones and laptops out of the bedroom
🍲 Nutrition: Fuel for Growth and Repair
Every training session, rehab exercise, or demanding day uses up fuel and causes small amounts of tissue damage. Nutrition is how you give your body the raw materials it needs to rebuild and adapt.
Here’s how good nutrition helps recovery:
- Protein supplies amino acids to rebuild muscle, tendons, and connective tissue (aim for ~0.8g/kg of body weight, or 1.6–2.2g/kg if you’re training hard)
- Carbohydrates restore energy (glycogen) and prevent muscle breakdown
- Healthy fats (especially omega-3s) fight inflammation and support joint health
- Micronutrients like vitamin D, calcium, magnesium, and zinc support tissue and bone repair
- Hydration keeps blood flow and nutrient delivery running smoothly
When nutrition falls short, recovery slows, tissues stay irritated, and fatigue piles up — often showing up as nagging injuries, plateaus, or slow rehab progress.
✅ Takeaway: Food isn’t just fuel — it’s building material. Aim for balanced meals with lean protein, complex carbs, healthy fats, and plenty of colorful fruit and veg. And drink water throughout the day.
- Prioritise protein at every meal (palm-sized portion — about 20–40g) to repair muscles and connective tissue
- Balance your plate: ½ veggies/fruit, ¼ lean protein, ¼ wholegrain carbs
- Stay hydrated: aim for about 2+ litres of water daily (more if you sweat a lot)
- Prep easy recovery snacks like Greek yoghurt, boiled eggs, fruit + nuts, or a protein smoothie for busy days
😮💨 Stress: The Silent Performance Killer
Stress isn’t just “in your head.” It directly affects how your body heals, performs, and even how much pain you feel. A bit of stress can sharpen focus, but chronic stress holds you back.
High stress levels can:
- Raise cortisol, which suppresses growth hormone and slows healing
- Increase muscle tension, leading to flare-ups or new injuries
- Amplify pain signals, making discomfort feel worse
- Disrupt sleep and eating habits, creating a vicious cycle
On the flip side, managing stress creates the perfect environment for your body to recover. Even small daily habits — like deep breathing, mindfulness, or walking outdoors — can lower stress hormones, improve blood flow, and calm your nervous system.
✅ Takeaway: Stress is part of life, but unmanaged stress will drag down recovery and performance. Make stress-management part of your routine just like you do with workouts and meals.
Simple ways to manage stress daily:
- Mini reset breaks: 2–3 short pauses each day for deep breathing, stretching, or stepping outside
- Breathwork: try the “4-7-8” technique — inhale 4 sec, hold 7 sec, exhale 8 sec (3–5 rounds)
- Gentle movement: walking, yoga, or light cycling on rest days helps flush stress hormones
- Social connection: make time with friends or family to boost mood and lower tension
