Sleep Sleep is associated with a state of muscle relaxation and reduced perception of environmental stimuli. Sleep is a naturally recurring state of mind and body, characterized by altered consciousness, relatively inhibited sensory activity, inhibition of nearly all voluntary muscles, and reduced interactions with surroundings. It is distinguished from wakefulness by a decreased ability to react to stimuli, but is more easily reversed than the state of being comatose. Sleep occurs in repeating periods, in which the body alternates between two distinct modes known as non-REM and REM sleep. Although REM stands for rapid eye movement, this mode of sleep has many other aspects, including virtual paralysis of the body.

Sleep Studies Sleep studies are painless, noninvasive tests that measure how well you sleep and how your body responds to sleep problems. The more common sleep studies monitor and record data about your body during a full night of sleep. Other types of sleep studies include multiple sleep latency and daytime maintenance of wakefulness tests. Multiple sleep latency tests measure how quickly you fall asleep during a series of daytime naps and use sensors to record your brain activity and eye movements.

What is Sleep? During sleep, we usually pass through five phases of sleep: stages 1, 2, 3, 4, and REM (rapid eye movement) sleep. These stages progress in a cycle from stage 1 to REM sleep, then the cycle starts over again with stage 1 (see figure 1).arcolepsy affects an estimated 250,000 Americans. People with narcolepsy have frequent sleep attacks at various times of the day, even if they have had a normal amount of night-time sleep. These attacks last from several seconds to more than 30 minutes.

Why do I sleep better during the day than at night One way to think about the function of sleep is to compare it to another of our life-sustaining activities: eating. Hunger is a protective mechanism that has evolved to ensure that we consume the nutrients our bodies require to grow, repair tissues, and function properly.

What is REM sleep? What is REM sleep? The brain cycles through five distinct phases during sleep: stages 1, 2, 3, 4, and rapid eye movement (REM) sleep. REM sleep makes up about 25% of your sleep cycle and first occurs about 70 to 90 minutes after you fall asleep. Because your sleep cycle repeats, you enter REM sleep several times during the night. During REM sleep, your brain and body are energized and dreaming occurs.

- The study followed participants who each took up residence for 38 days at Brigham and Women's Hospital in Boston. They had five days to catch up on sleep, then spent 21 days on a sleep cycle of about 33 hours awake and 10 hours asleep. The study looked at three things: the number of consecutive hours awake, the number of days or weeks of chronic sleep reduction, and what time it was in the person's day.

Is sleep that important? There have been thousands of sleep studies performed over the years, but we still aren't exactly sure why we sleep.

Sleep is not actually  unconsciousness , but rather, it is a natural state of rest characterized by a reduction in voluntary body movement and decreased awareness of the surroundings. Stage 5, or Rapid eye movement (REM) sleep, associated with dreaming, especially bizarre, visual, and seemingly random dreams. 2  REM sleep is predominant in the final third of a sleep period, its timing linked to circadian rhythm and body temperature.

- REM sleep typically occupies 20–25% of total sleep each night. REM sleep, when dreaming occurs, is essential to our minds for processing and consolidating emotions, memories and stress. It is also thought to be vital for learning, stimulating the brain regions used in learning and developing new skills.

The Importance of REM sleep REM sleep is important because it is the restorative part of our sleep cycle. Typically, you begin the sleep cycle with a period of non-REM sleep followed by a very short period of REM sleep. The period of non-REM sleep is made up of stages 1 to 4. Each stage can last from 5 to 15 minutes.

Stages of Sleep Sleep cycles through these stages approximately 4 or 5 times throughout the night. We typically enter REM approximately 90 minutes after falling asleep. The first cycle of REM often lasts only a short amount of time, but each cycle becomes longer. This is why we need long periods of sleep each night. If we get short periods of sleep, we can’t really get through the stages we need to heal and stay healthy. REM can last up to an hour as our sleep progresses.

- REM sleep is sometimes referred to as paradoxical sleep by scientists because it is a period of sleep characterized by rapid periodic twitching movements of the eye muscles and other physiological changes, such as increased breathing and heart rate, increased brain activity, and muscle relaxation.asically: you look asleep, but your brain is wide awake. REM sleep is when we remember our dreams, so it makes sense that our brains are most active when we are dreaming, seeing as that dreams require a lot of mental activity. 14 people found this useful.

This sleep drive gets stronger every hour you are awake and causes you to sleep longer and more deeply after a period of sleep deprivation.

The Purpose of Sleep? To Forget, Scientists Say In laboratory experiments on clumps of neurons, scientists can give them a drug that spurs them to grow extra synapses. Afterward, the neurons pare back some of the growth. Other evidence comes from the electric waves released by the brain. During deep sleep, the waves slow down.
