Blood flow is directed away from your brain and towards your muscles, restoring physical energy. In this deepest stage of sleep, your brain waves are extremely slow. Third stage also known as "deep sleep" – in this stage it's difficult to awaken, and if you forcibly wake up, you do not adjust immediately and often feel groggy and disoriented for several minutes.
Your eye movement stops, heart rate slows, and body temperature decreases. Second stage also known as "light sleep" – This is the first stage of true sleep, lasting from 10 to 25 minutes. Your eyes move slowly under the eyelids, muscle activity slows down, and you are easily awakened. Each cycle typically lasts about 90 minutes and repeats four to six times over the course of a night.įirst stage also known as "transitional sleep" – it lasts for about five minutes.
