Frequent or prolonged daytime naps can disrupt healthy nighttime sleep. Napping during the day may make it harder to fall asleep at night or cause nighttime sleep to become fragmented. If you experience insomnia or poor sleep quality at night, napping might worsen these problems.

①

Reduce blue light exposure in the evening

The blue light that your phone, laptop, and TV affect your circadian rhythm, tricking your brain into thinking it's still daytime. This reduces hormones like melatonin, which help you relax and get deep sleep. It's recommended that you stop using electronics at least an hour before bed.

②

Set your bedroom temperature

Body and bedroom temperature can also profoundly affect sleep quality. Studies reveal that increased body and bedroom temperature can decrease sleep quality and increase wakefulness. Around 70°F (20°C) seems to be a comfortable temperature for most people, although it depends on your preferences and habits.

③

Create a bedtime routine

Having a bedtime routine means that you consistently perform activities that wind you down for sleep. Repeating your routine each night will help signal to your body that it's almost time to rest. Some examples of activities in bedtime routines include taking a warm shower, doing some light stretching and reading a few pages of a book.

④

Exercise regularly

Exercise is one of the best science-backed ways to improve your sleep and health, it can enhance all aspects of sleep and has been used to reduce symptoms of insomnia. Although daily exercise is key for a good night's sleep, performing it too late in the day may cause sleep problems.
