Sleep
Sleep is a cornerstone of men’s health, influencing hormone balance, metabolic function, and overall longevity. Understanding how circadian rhythms and sleep quality interact helps you make practical tweaks that boost energy, recovery, and performance without relying on unverified claims.
Key takeaways
- ✓Consistency (same sleep/wake time) is more powerful than duration alone.
- ✓Alcohol significantly degrades sleep quality even at low doses.
- ✓Temperature is one of the most underrated sleep levers.
- ✓Fix sleep before adding any supplement protocol.
- ✓Chronic short sleep raises cortisol and reduces testosterone.
Where to start with sleep optimisation
- 1Set a consistent sleep and wake time, even on weekends.
- 2Keep your bedroom cool (16–19°C) and dark.
- 3Avoid screens for 30–60 minutes before bed or use blue-light blocking.
- 4Limit caffeine after 2pm — its half-life is 5–7 hours.
- 5Track your sleep for one week with a wearable or sleep diary before adding supplements.

Common myths about sleep
Myth: “I can catch up on sleep at the weekend.”
Reality: Chronic sleep debt cannot be fully repaid in a weekend. Cognitive impairment accumulates over time with insufficient sleep.
Myth: “You need less sleep as you get older.”
Reality: Sleep architecture changes with age, but the need for 7–9 hours remains. Older adults often sleep lighter and wake more.

Frequently Asked Questions
›How many hours of sleep do men aged 30‑55 actually need for optimal health?
Most research suggests 7–9 hours per night supports hormone regulation, cognition, and metabolic health in adults, including men in the 30‑55 age range.
›Can poor sleep lower testosterone levels?
Evidence shows that chronic sleep restriction can modestly reduce testosterone, especially when sleep falls below 7 hours, but the effect varies among individuals.
›What are the most effective, evidence‑based strategies to improve sleep quality?
Maintaining a consistent bedtime, limiting blue‑light exposure before bed, keeping the bedroom cool and dark, and avoiding caffeine or heavy meals late in the day are consistently linked to deeper, more restorative sleep.
›How do circadian rhythms affect sleep, and can they be reset?
Circadian rhythms synchronize sleep‑wake cycles with light exposure; exposure to natural morning light and dimming lights in the evening can help reset the internal clock and improve sleep timing.
›Is a “100% sleep score” realistic, and should I aim for it?
Sleep‑tracking scores are algorithmic estimates and not medical diagnostics; focusing on consistent habits and feeling rested is more meaningful than chasing a perfect numeric rating.
