Wake Up During Your Lightest Sleep


By Azumio, Inc.


Our body’s sleep cycle is always changing and for the average adult, managing to get enough sleep is not usually our priority.

While some people choose to sleep less than the recommended eight hours and others simply cannot make the time, it’s important to know how to capitalize on the few hours of sleep we do manage to capture by understanding our sleep cycles. 

A very beneficial way to wake up refreshed despite minimal sleep is to wake up during a period of your lightest sleep. Being woken in a light stage of your sleep cycle has proven to make people feel more energetic and alert upon awakening. 

When you fall asleep, you experience rapid eye movement (REM) sleep and non-REM sleep throughout the night. The beginning stages of sleep prepares your body to shut down. During this stage, you can be easily awakened by noise or thoughts. The middle stages involve light sleep usually lasting anywhere from 10-25 minutes. Deep sleep occurs in the later stages when activity in the body is low and activity in the brain is very high. REM sleep is the last stage of the sleep cycle where for about 70-90 minutes we are in our deepest sleep. This is the stage of sleep where we dream; when we are awoken during this stage, we often feel disoriented. 

These cycles repeat throughout the night and into the morning. Waking up in the beginning stages of your sleep cycle is important because our bodies aren’t entirely shut down. Meanwhile, being awoken in the middle of REM sleep can cause grogginess that has the potential to last throughout the morning and even throughout the day. This explains why sometimes even when we sleep for eight or nine hours, we can sometimes still feel like we barely got any rest at all.
