A typical nights sleep consists of about 5 6 full sleep cycles. As the night unfolds an uninterrupted sleeper may not spend much more time in stage 1 as they move through further sleep cycles.

Stage 2 n2. During these sleep cycles our breathing heart rate muscles and brain waves. Stage 2 usually follow stage 1 and represents deeper sleep.

We go through several sleep cycles each night and the length of each rem cycles is longer for each new cycle. At the same time brain waves show a new pattern and eye. The eeg brain frequency is slightly slower than during wake time.

During the first 2 3 sleep cycles you spend most of the time in a deep nrem sleep. This number gradually gets higher as the night progresses. This period of sleep lasts only a brief time around five to 10 minutes.

You are in light sleep. A full sleep cycle is 90 minutes. But spending too much time indoors may be disrupting it.

In stage 1 the brain produces high amplitude theta waves which are very slow brain waves. The sleep wake cycle is regulated by the bodys internal 24 hour clock the circadian rhythm. There is muscle tone present in the skeletal muscles.
