Poor sleep is one of the most common complaints in the modern world, and one of the most under-addressed. Most people accept bad sleep as part of life. It does not have to be.
What actually works
1. Same time every day. Your body clock (circadian rhythm) thrives on consistency. Going to bed and waking at the same time — even on weekends — is the single most impactful change you can make.
2. No screens for 60 minutes before bed. Blue light from phones and laptops suppresses melatonin production, the hormone that signals sleep. The effect is real and measurable.
3. Keep your bedroom cool. The optimal room temperature for sleep is around 16-19°C. Your body needs to drop its core temperature to initiate sleep.
4. Avoid caffeine after 2 PM. Caffeine has a half-life of 5-7 hours. A 4 PM coffee still has half its caffeine in your system at 9 PM.
5. Get morning sunlight. Even 10 minutes of natural light in the morning helps anchor your body clock and sets up earlier melatonin release at night.
6. Cut alcohol. Alcohol disrupts REM sleep. Even one or two drinks shift your sleep architecture in ways that leave you less rested than you feel.
7. Exercise, but not too late. Regular moderate exercise significantly improves sleep quality. Avoid intense exercise within two hours of bed.
8. Write down tomorrow's worries. A five-minute "worry dump" on paper before bed reduces the mental chatter that keeps many people awake. It is a form of planned problem-solving that allows the brain to let go.
