A note before we start. Loud snoring, gasping at night or heavy daytime sleepiness can be signs of sleep apnoea — see your GP. Ongoing insomnia deserves medical advice too. This is general information, not medical advice. LifeWave products are not sleep aids and not a treatment for any condition.
If there’s one lever that affects nearly everything else about how you age, it’s sleep. Short or poor sleep is linked with higher inflammation, worse blood-sugar control, lower testosterone and slower recovery. The good news: it’s one of the most fixable inputs you have.
Key takeaways
- Deep sleep is when much of the body’s repair work happens.
- A fixed wake time and morning light anchor your body clock.
- A cool, dark room and less late alcohol improve sleep quality.
- Habits beat supplements.
What happens during sleep
- Much of the day’s growth hormone is released in early deep sleep.
- The brain’s waste-clearance (glymphatic) system is more active during sleep.
- Cortisol falls to its lowest point early in the night.
- Short sleep is associated with higher inflammatory markers.
Seven habits that help
1. Fix your wake time, seven days a week.
2. Get morning light within half an hour of waking.
3. Keep the bedroom cool — around 16–19°C suits most people.
4. Stop alcohol earlier. It fragments sleep and suppresses REM.
5. Dim the lights in the last couple of hours before bed.
6. Consider magnesium if your intake is low. Keep supplements within the label dose and the upper limit (250mg a day from supplements in the EU). I take magnesium before bed. See magnesium.
7. Watch caffeine after early afternoon.
Tracking
Wearables estimate sleep stages, heart-rate variability and resting heart rate. They’re imperfect but useful for trends. I wear a WHOOP.

Frequently asked questions
How much sleep do I need?
Seven to nine hours for most adults. Quality matters as much as quantity.
Does alcohol really affect sleep?
Yes. It helps you nod off but fragments sleep later in the night.
Which supplements help?
Evidence is modest. Magnesium may help if you’re low. Melatonin is prescription-only in Ireland and the UK; ask your GP. Habits outperform supplements.
Does any LifeWave product treat sleep problems?
No. No such claim is made. LifeWave products are not intended to diagnose, treat, cure or prevent any disease.
