90 Minute Sleep Cycles

If you wake up tired and groggy in the morning, you may be waking up during a sleep cycle.

Our sleep is divided into several cycles (rem, deep sleep) and each of these lasts for 90 minutes on average. 

If you want to wake up feeling renewed and refreshed it is beneficial to wake up in between sleep cycles. There is a wonderful tool that I use with clients to help them calculate the time they should go to sleep and wake up in the morning. https://sleepyti.me

By waking up in between sleep cycles it makes the transition from sleeping to being awake a much easier one.
