The Complete Sleep Hygiene Guide for 2026
Evidence-based sleep hygiene practices to improve your sleep quality. From bedroom environment to daily habits, learn what science says about getting better sleep.
Sleep hygiene refers to the habits and environmental factors that promote consistent, quality sleep. While sleep products can help, the foundation of good sleep starts with your daily routines and bedroom setup.
Temperature matters more than most people realize. Research consistently shows that a bedroom temperature of 65-68 degrees Fahrenheit (18-20 degrees Celsius) is optimal for sleep. A cooling weighted blanket or breathable sleep mask can help if your room runs warm.
Light exposure is a critical signal for your circadian rhythm. Get bright light exposure in the morning and limit blue light in the evening. A quality sleep mask can help if you cannot fully darken your room, and a sunrise alarm can help you wake more naturally.
Sound management is essential, especially in urban environments. Consistent white or pink noise can mask disruptive sounds and create a sleep-conducive environment. The key is consistency: your brain habituates to steady sounds but stays alert to sudden changes.
Scent is an underutilized sleep tool. Lavender has been shown in multiple studies to increase slow-wave (deep) sleep. A bedside diffuser running for 30 minutes before sleep can help signal your brain that it is time to wind down.
Consistency is the most important factor. Going to bed and waking up at the same time every day, including weekends, is the single most effective sleep hygiene practice. Use your sleep products to build and reinforce this routine.
