Sleep compared to adult and children

There are individual differences in the amount of sleep you need in person, 7 - In the case of 8 hours in many cases. According to the research of Nagoya University School of Medicine Graduate School of Tamakoshi Akiko Sleep medicine published papers of Daniel Kripke, et al at the University of California at San Diego and , sleep time of day risk of death compared to people of other people 7 hours (it is not known, however, whether or not the less likely to die long and people who sleep time is short if to 7 hours sleep time) low.

Chronic insomnia that is 2.1 times increase the risk of mental illness, including depression Depression by insomnia. Insomnia, Kanemu is seen in 10% to about 80% of the depression.
People sleep time is short, often ghrelin leptin to suppress appetite in the blood enhance the appetite less. As a result, the risk of becoming obese appetite is likely to be increased as sleep time is shortened increases.

It is necessary to take a long sleep compared to adult children. During sleep, organize efficiently by omitting the extra information from the information that you have to experience and learning during the day, lack of sleep is treated as a memory and sense of long-term (brain tremendous impact on academic performance and physical ability of the child that). And though such while learning the amount of children increases, (← When?) Amount of sleep in order to process what you have learned is cut more and more recently.

It can be used to eliminate the lack of sleep by taking a long sleep in the next day you have a night owl, but is that it can not then sleep for a long time the day before to the contrary, such as to stay up late the next day "pooled sleeping". Also, "sleeping together", lack of sleep can be solved, such as the former, but is it not good for the quality of sleep and down by the long sleep, to break the rhythm of sleep and body balance.

There are individual differences in the ease of taking sleep. In addition, because it depends mental state and physical condition, the external environment of falling asleep, you can sleep easy birds, etc. or difficult birds sleep, difference due to state is larger in the same individual. Therefore, ammine process for taking pleasant sleep is a number invention. Since the activity is enhanced by an increase in body temperature, it is possible to warm the bedroom when falling asleep or bathing before falling asleep is effective hypnagogic neurons, which will be described later. The melatonin is involved in the sleep, there is a need to take a light of 2500 lux or more during waking To generated by the pineal gland in the brain melatonin

Sleep in humans, can be classified on the basis of the eye movement and brain wave is known. Adult was repeated during sleep between stage I ~ REM, cycle is 90 minutes. Stage I and falling asleep - a special group of neurons responsible for the transition of REM sleep between the IV exists. Hypnagogic neurons present in the (ventrolateral preoptic area) brain base is activated prior to falling asleep. REM sleep onset neurons of cholinergic located in the brain stem to activities in REM sleep during migration. Each neuron in the brain has been working independently in the waking state, but Stage I - to activities adjacent neurons in IV is synchronized at a low frequency.
