Longer naps, such as those lasting more than 30 minutes, can cause the sleeper to enter deep sleep, and deep sleep may start even sooner in people who are sleep deprived.
This can actually make it easier to wake up refreshed from a quick nap. In fact, during a short nap, a person may not be asleep long enough to spend much, if any, time in stage 3 or REM sleep. During a nap, though, there is not enough time to go through multiple sleep cycles. When sleep periods last several hours, the body cycles through these stages several times. Dreaming tends to take place during REM sleep. Rapid eye movement (REM): During REM sleep, the body’s muscles are temporarily paralyzed, and the eyes move quickly under closed eyelids.Stage 3 usually lasts between 20 and 40 minutes. Stage 3: Stage 3 is a deeper, more restorative stage of sleep, and it can be difficult to wake up while in this stage.However, sleep in this stage is still relatively light. During stage 2 sleep, the muscles relax, and body functions slow. Stage 2: Stage 2 follows stage 1 and lasts about 10 to 25 minutes.Stage 1: Stage 1 is the lightest and briefest stage of sleep, lasting only one to seven minutes.
