Sleep Hygiene: Practical Habits That Actually Help

Consistency in sleep and wake times

Going to bed and waking up at roughly the same time daily, including weekends, supports a more stable circadian rhythm than a schedule that varies significantly between weekdays and weekends.

Optimizing the sleep environment

A dark, cool, quiet room generally supports better sleep quality than a bright, warm, or noisy one — relatively simple environmental adjustments that meaningfully affect sleep quality for many people.

Managing light exposure throughout the day

Bright light exposure in the morning and reduced light (particularly blue light) in the evening helps reinforce a healthy circadian rhythm, supporting both easier sleep onset and better morning alertness.

Being mindful of caffeine and alcohol timing

Caffeine's roughly 5-6 hour half-life means afternoon consumption can meaningfully affect that night's sleep; alcohol, despite feeling sedating initially, tends to disrupt sleep quality later in the night.
