Consciousness state In 1960, a man named W. Dement conducted a series of sleep-related research. His main goal is to understand and understand the influence of deprivation of dreams. His strategy will be very useful to quickly answer some very complicated questions. He started with observing the baby while sleeping, but he did not realize he could not get oral feedback from the newborn. Then he decided to choose 20 random adults as his penis pig.

Sleep is divided into two broad categories: non-rapid eye movement (non-REM or non-REM) sleep and rapid eye movement (REM) sleep. Since non-REM sleep and REM sleep are very different, physiologists recognize them as different behavioral states. NonREM sleep first occurs and is called slow wave sleep or deep sleep after the transition period. At this stage, body temperature and heart rate are lowered, and brain energy consumption is reduced. REM sleep, also known as abnormal sleep, occupies a small part of total sleep time. It is the main opportunity for dreams (or nightmares) related to loss of synchronization and rapid brain waves, eye movements, loss of muscle tone and cessation of homeostasis.

Let's take a look at the two sleep stages of the sleep cycle, REM sleep and non-REM sleep. REM sleep is essential to the brain: it consolidates memory and helps deal with emotions. Non-rapid eye movement sleep means body recovery, growth hormone release and cell repair. Good night sleep requires about 5 complete sleep cycles. Well, Serge goes through 4 sleep cycles every night. rMSSD is an HRV parameter that can be measured using ouraRing, heart rate monitor, or smartphone camera. This is one of the parameters used to evaluate recovery after exercise or stress event. Serge's rMSSD number is relatively low, so I am over-used at the gym or have received a lot of pressure.

There are two types of sleep: REM sleep and non-REM sleep (3 levels). Each is related to a specific brain wave and nerve activity. In a typical evening, you can repeat several stages of non-REM sleep and REM sleep, and the REM cycle towards the morning is longer. Stage 1's non-REM sleep is a transition from waking up to sleeping. During this relatively light sleep (several minutes) your heart beat, breathing, and eye movements will be slow and your muscles will relax during occasional cramps. Your brainwave begins to slow down from wake-up mode.
