Why rest matters as much as exercise
Sleep is a vital part of how our bodies and minds recover, reset, and stay healthy. Whether you’re juggling deadlines, managing teams, or balancing life and work commitments, better sleep and intentional recovery habits can help you feel better today and build resilience for the long term.
In the article, Dr Alan Twomey, Clinical Lead & GP at Teladoc Health UK shares simple, evidence-based tips to improve sleep quality.
Sleep plays a crucial role in long-term wellbeing, immune function, and even chronic disease prevention. During sleep, your body clears accumulated toxins, supports immune responses, repairs tissue, and regulates hormones that influence appetite and respond to stress - hormones like leptin and cortisol. Habitually poor sleep, especially getting less than the recommended 7–9 hours for most adults, is associated with higher risks of cardiovascular disease, type 2 diabetes, obesity, and weakened immune responses.
But the benefits aren’t just physical. Sleep strengthens memory, supports emotional regulation, boosts mood, and helps with decision-making and focus, all skills that matter at work and at home.

Sleep is restorative in both the short and long term. In the short term, it replenishes energy, supports mood regulation, and enhances alertness. Over time, consistently good sleep patterns help guard against chronic illnesses like heart disease and type 2 diabetes, and they strengthen emotional resilience.
Better stress management
Sleep supports healthy regulation of stress hormones. Without enough sleep, the body remains in a higher stress-alert state, which over time can contribute to burnout, anxiety, and poor decision-making.
Stronger immune function
When you sleep well, your immune system can fight off infections, support healing, and reduce inflammation, which is a key factor in many chronic diseases.
Mental health and cognitive function
Regular, quality sleep boosts memory, problem-solving, and emotional balance. Poor sleep, on the other hand, is linked with mood disorders and reduced cognitive performance, which could affect both productivity and quality of life.
Here are straightforward evidence-based practices that can help anyone improve their sleep quality and support recovery:
Set a consistent sleep schedule
Going to bed and waking up at roughly the same time every day helps regulate your body clock (your circadian rhythm) and improves how easily you fall asleep and how rested you feel in the morning.
Create a relaxing pre-sleep routine
Wind-down habits signal to your brain that it’s time to stop and reset. This could include:
These low-pressure activities help the nervous system shift from “work mode” to “rest mode”.
Mind your daytime habits
Simple daytime choices influence how well you sleep at night:
Keep your sleep environment cool and quiet
A dark, cool, quiet bedroom makes it easier for your body to drift into restorative sleep stages, during which tissue repair and brain recovery are most active.
Low-pressure wind-down routines for busy schedules
If your day feels non-stop, short wind-down rituals can still make a big difference. These are not rigid rules - they’re flexible routines that fit into your evening, even on hectic days:
Comfort first
Taking a warm shower or bath before bed can help lower body temperature afterwards, which encourages sleepiness.
Screen-light swap
Instead of scrolling social media or emails right before bed, switch to reading a physical book, journalling, or listening to soft music.
Mindful minutes
Five minutes of mindful breathing or meditation before sleep can slow your heart rate and ease stress. Simple breathing techniques can be learned online or via apps.
Quick reflection
Ask yourself: What’s one small positive from today? Reflecting briefly on positive moments can ease stress-driven thoughts that disrupt sleep.
These routines don’t require extra hours, just intentional moments that help your mind let go of the day.
Small changes in behaviour like these can bring immediate improvements in sleep quality, and over time, these habits support greater long-term health and better stress tolerance. However, if sleep difficulties persist despite good habits, it can be helpful to consult a clinician or sleep specialist.
