How much do i have to sleep

In Today’s corporate world, this is a big question popping at everybody’s mind. We should spend up to one-third of our lives asleep. Most of us know that getting a good night’s sleep is important, but few of us actually make those eight or so hours between the sheets a priority .Some people claim to feel rested on just a few hour of sleep a night. 

Sleep is a naturally periodic state of humans characterized by altered consciousness, relatively subdued sensory activity, inhibition of nearly all voluntary muscles, and reduced interactions with surroundings. It is illustrious from wakefulness by a decreased ability to react to stimuli, but is more easily reversed than the state of hibernation. During sleep, most systems in an humans are in a delicate anabolic state (Constructive phase), accentuating the growth and rejuvenation of the immune, nervous, skeletal, and muscular systems

            In humans, sleep deprivation has been studied up to 11 days, during which subjects are found to gain weight. Human deaths from sleep deprivation alone are not known. Sleep debt is the effect of not getting enough sleep; a large debt causes mental, emotional, and physical fatigue. Sleep debt results in reduced abilities to perform high-level intellectual functions. Sleep deprivation tends to cause slower brain waves in the frontal cortex, shortened attention span, higher anxiety, diminished memory, and a irritable mood. A well-rested human tends to have improved memory and mood.

Lack of sleep can double the risk of death from cardiac disease, but that too much sleep can also be related with a doubling of the risk of death. Sleep difficulties are closely associated with psychiatric disorders such as depression, alcoholism, and bipolar disorder. Up to 90% of adults with depression are found to have sleep problems.

Human sleep needs vary by age and among individuals. Adequate sleep is considered, when there is no daytime sleepiness .An average adult needs between 7.5 and 9 hours of sleep per night. However, many people can function with 6 hours' sleep. The amount of sleep needed to function the next day varies from individual to individual, and is determined genetically and hereditary. A person's major sleep period is relatively useless and insufficient when it occurs at the "wrong" time of day; one should be asleep at least six hours before the lowest body temperature.
