Sleep is indeed mysterious, and monitoring it is a complicated task. In the REM Sleep stage, the brain activity shows signs of acceleration, and the human body undergoes atonia, a condition when the complete body, except your eyes and breathing muscles, gets paralyzed. It is in this stage that the body recovers, grows, and strengthens the immune system. The brain activity shows a familiar delta wave pattern. The muscles relax further, and the pulse and breathing rate decrease even more in this stage. Stage 3 / N3 is what we call deep sleep, and waking up someone in this phase becomes even harder. Stage 2 lasts for up to 10-25 minutes, and the brain activity slows down and can get even longer during the night time. The breathing and heart rate gradually slows down as the body enters a quiet stage with no eye movements. Stage 2 / N2 is characterized by a drop in the body temperature and muscle relaxations. If not, they will quickly transition into stage 2. An individual can be easily woken up in this stage. ![]() Here the body is not in a completely relaxed state, but the body and brain activity slows down. Stage 1 / N1 is what we generally call the dozing-off stage, which typically lasts five to ten minutes. The four different stages depict distinct brain activities during sleep and are discussed below. The four sleep stages are classified into two broad categories- rapid eye movement (REM) sleep and non-REM (NREM) sleep. Each stage plays a crucial role in keeping your mind and body at rest to stay refreshed all day long. Sleep is not uniform but comes in the form of cycles that progress smoothly from each of the four different sleep stages of non-uniform length. Sleep comprises several stages into which human beings keep oscillating while they are asleep forming a sleep cycle. While the duration of your sleep is important, you shouldn’t neglect the sleep quality to comprehend whether the time you slept sleeping was rewarding or not. The main causes behind it are a sedentary lifestyle, professional work stress, and several personal reasons. People of all ages suffer from sleep loss, insomnia, and poor sleep quality, which lead to several mental and physical health issues. ![]() Getting enough sleep is essential to achieving optimal health and maintaining overall well-being thus, the inability to get enough sleep can take a toll on your health.
