Not only lack of sleep that can cause various health problems, too much sleep also may pose a risk to health. But some people just need time to sleep longer than normal bedtime.Not just resting the muscles, during sleep the body undergoes repair and detoxification (remove toxins). Sleep also gives an opportunity for the immune system to produce hormones immunity (immune system), thus greatly affect the physical and mental health.
Reason is what makes some people with certain conditions require a longer sleep time sleep time than normal adults, ie 7-9 hours.
Here are some people who need extra time to sleep, as reported by mayoclinic on Monday (4/11/2011), namely:
Infants and children
The younger the age of the child so the more hours sleep. The experts correctly set bedtime can improve sleep quality and quantity of infants and toddlers. Children who are not getting enough sleep will have an impact on personality, memory, attention and emotions of the child. Usually the child will be irritable, unable to concentrate and have a weak memory.
Here is the number of hours of sleep a child needs based on age according to the National Sleep Foundation:
Newborns (0-2 months) require 10.5 to 18 hours sleep
Babies (3-11 months) need to sleep 9 to 12 hours and added with a nap
Children (1-3 years) need to sleep 12 to 14 hours
Children (3-5 years) need to sleep 11 to 13 hours
Children of school age (5-12 years) need to sleep 10 to 11 hours
Teens (10-17) need to sleep at least 8.5 to 9.5 hours
Adults need to sleep 7 to 9 hours.
Pregnant women
Woman's body changes during pregnancy can increase the need for sleep. Pregnant women usually need extra time to sleep in the first trimester.
People with weak immune
People who are sick, recovering and has a low immune system also requires a longer sleep time than normal bedtime. When the immune system is suppressed, the body produces chemicals to fight infection, these chemicals are usually produced at rest or sleep.
Patients with anemia
Poor nutrition, lack of sleep, too tired can be a cause of anemia or anemia disease.This condition could worsen if the intake of nutrients and sleep needs are not met properly.
The people with the above conditions do require a longer time to sleep. But for healthy adults, should not be too much sleep. Sleep with sufficient time.
If lack of sleep can be harmful to health with a trigger obesity, diabetes and heart disease, then slept over at a normal person can also be dangerous.
Studies show people who regularly sleep more than 8 hours per night at greater risk of stroke than others with less sleep.
The factors that allow someone to sleep hypersomnia is excessive or have poor quality sleep, so it can not properly regulate sleep schedule. And estimated genetic factors also play a role.
