Rapid Rem Sleep Waves example essay topic
It is a fact that blind people do not experiance REM sleep. Also known as paradoxical sleep because the muscles are relaxed (except for minor twitches) but other body systems are active. The regular alpha waves of an awake, relaxed state are quite different from the slower, larger delta waves of deep Stage 4 sleep. Although the rapid REM sleep waves resemble the near-waking Stage 1 sleep waves, the body is more aroused during REM sleep than during Stage 1 sleep. The six Stages of sleep are as follows... Awake, relaxed, Stage 1 sleep, Stage 2 sleep, Stage 3 sleep.
Stage 4 sleep, and as we know as most effective and active... REM sleep. There are a few disorders caused by REM sleep that are common yet may not be. It's very likely you might experiance one of these disorders often. The most common disorder is the common nightmare. Night mares are vivid, frightening dreams that cause people to wake suddenly with feelings of fear, anxiety, and foreboding.
The dream is often recalled vividly, and it's often difficult to fall back asleep after a nightmare. Children experiance more nightmares than adults. Scary dreams start as early as eighteen months, and increase over time. By age four and five, many children have nightmares as often as once or twice a week.
This is a normal phase in child development, and generally dose not require treatment. Children do however need comfort and reassurance after a nightmare. There is a REM disorder also known as RBD, Rapid eye movement Behavior Disorder. It is a serious REM sleep disorder that can cause injuries. The body usually experiance a tonia which is a temporary paralysis during dreaming. This is a safety precaution that prevents us from physically acting out our dreams.
In RBD, this paralysis is either insufficient or entirely lacking and the affected dreamer may act out exciting or violent dreams.
