Your body’s internal clock, a.k.a. your circadian rhythm, plays a key role in regulating your sleep-wake cycle. This clock tells your body when it’s time to wake up in the morning and when to start unwinding at the end of the day.

Your sleep cycle is closely linked to light in your environment, so your internal clock helps you naturally feel more awake during daylight hours and more tired at night. Ideally, you should stick to the same sleep schedule every night so your body can find its natural rhythm and settle into a regular sleep-wake cycle. #sleepcycle #healthyliving #bedtime
