Sleep Hygiene

Sleep hygiene refers to a set of habits and practices that promote consistent, high-quality sleep and support a healthy circadian rhythm. Good sleep hygiene helps regulate sleep patterns, improve overall well-being, and reduce the risk of sleep disorders.

Key Principles of Sleep Hygiene

  • Consistent Schedule: Go to bed and wake up at the same time every day, including weekends.

  • Optimized Sleep Environment: Keep your bedroom dark, quiet, and cool to create an ideal sleep setting.

  • Avoid Stimulants: Limit caffeine, nicotine, and heavy meals close to bedtime.

  • Limit Screen Time: Reduce exposure to blue light from electronic devices at least 1–2 hours before sleep.

  • Engage in Relaxation: Incorporate calming activities like reading, meditation, or light stretching before bed.

Why Is Sleep Hygiene Important?

  • Better Sleep Quality: Improves the duration and depth of sleep.

  • Circadian Alignment: Reinforces natural sleep-wake cycles for better circadian health.

  • Long-Term Health Benefits: Reduces the risk of chronic conditions such as insomnia, fatigue, and cardiovascular issues.

Practicing good sleep hygiene is essential for achieving restorative sleep and maintaining optimal mental and physical health.
