There two stages are categorized at light sleep. Stage three is when it starts to become harder to awaken the sleeper. Sleep spindles disappear and breathing slows down. Your brain also emits delta waves, which signify deep sleep. The fourth stage is the deepest sleep that normally lasts for about an hour and a half.
Despite their appearance, sleep terrors are not nightmares. Nightmares are vivid dreams that occur during REM sleep, and most people can recall most or all of their nightmares. ( http://stanfordhospital.org/clinicsmedServices/clinics/sleep/sleep_disorders/nighttime-sleep-behaviors.html) On the other hand, sleep terrors occur during the deepest stages of sleep when dreaming does not occur. Commonly one who has a sleep terror cannot recall what was so frightening to them. It is typical during a sleep terror for a person to scream, sweat, have a rapid pulse and sit up in bed.
There are differences between adult and infant sleep. At birth there is more active sleep than adult REM sleep; about half of infant sleep is spent in active sleep. As well as this, adults can usually go fairly directly into the state of deep sleep, whereas infants in the early months enter sleep through an initial period of light sleep. After 20 minutes or more they gradually enter deep sleep. By the age of 6 months a circadian rhythm is established and by the age of 1 year infants are usually sleeping mainly at night, with 1 or 2 naps during the day.
Surveys show that teens rely on naps to make them more refreshed. You should only take at the maximum a 45 minute nap anything more than that disrupts your biological clock and this is what causes you to wake up angry or irritable from a nap. Other factors also play a role in getting good night’s sleep. For example, caffeine plays a huge part in not getting any sleep, 31% of adolescents surveyed said that they cannot sleep after drinking a caffeine drink before bed. Technology also has a huge role in not getting to sleep.
Everyone can say that their fine with just a few hours of sleep, which in this case is not okay because my body and mind need a certain amount of sleep. Without sleep our mind will not be able to function as thriving as he or her want it to be. Even without enough sleep our body will not be healthy enough to function properly, particularly at an older age. Thus mean that for the generation now and in the future, its best to control the amount of sleep everyone gets for his or her own
Experimental Research PSY/285 February 17, 2013 Experimental Research Pharmaceutical Research: Sleeping Aids There are many different kinds of sleeping aids that can help someone fall asleep today. Insomnia is when a person has a hard time falling asleep, staying asleep, or a disturbance in the quality of sleep a person gets that will make them feel they are not well rested when they do wake.

Insomnia has also been known to cause depression, anxiety, and stress, which in turn can cause other health problems.
Chapter Four: Consciousness: Sleep, Dreams, Hypnosis, and Drugs * Understanding consciousness necessarily involves subjective experience. * An altered state of consciousness that may also be a natural state could be sleeping and hypnosis. * Hypnogogic sleep typically lasts for five minutes. * Your brain first begins to produce delta waves in the third stage of sleep. * One’s genitals will typically be aroused during REM sleep provided one’s dream is not anxiety provoking.

They are events we intentionally put forth time and effort even when it is cutting into our sleep time, though at times they are unintentionally overlapping into our sleeping. An example of a person who reduces their sleep is a security guard working the night shift. Many individuals in that line of work regularly have to work either late hours, or, work through the night when we are accustomed to be sleeping. Same goes with law enforcement officers, or hospital nurses, or basically any kind of shift work. Sleeping habits for people in these fields of work are commonly irregular and inconsistent, which have an impact on their health.
Sleep paralysis is a condition that restricts the body from moving and at times speaking while in the transition of falling asleep or awakening (Wickens). There are two other sleep stages that must be addressed to show the steps of narcolepsy in the body. The first being nonrapid eye movement sleep (NREM) which is the first phase at the start of sleep (Nishino). NREM only occurs for about the first hour and a half of sleep then is followed by rapid eye movement(REM) sleep where dreaming takes place. It is common in normal sleep patterns to move in and out of REM and NREM sleep but it was found to be more increased among narcolepsy patients to move into REM more often than normal (Nishino).
