How Much Sleep Does a Person Need?

The amount of sleep a person needs depends on various factors. It includes age, health, recent physical exertion, and mental activity of that person. Genetic influence also plays a major role in determining the requirement of sleep. Some people need to sleep for more hours that runs in their family.

Getting The Right Amount of Sleep

If you are between 18 to 21, it is recommended that you need to sleep eight hours on an average. Adults aged over 21 need to sleep for 7 hours on an average. Infants, children, and teenagers need more sleep.

From the table, we can see that infants who are under 1 year of age need 16 to 20 hours of sleep on an average. Their sleeping time is reduced to 14 hours by the time they become 2 years old. Children who range from 3 to 4 years of old need 12 hours of sleep. their sleeping time is spread throughout the day. by the time they become 5 years old, their need for sleep reduces to 10 hours. At this age, they get most of their sleep at nighttime. Teenagers need around nine hours of sleep to function properly. Adults and seniors need 7 to hours of sleep every night.

For adults, the sleeping hours may vary depending on the person. Some people can function properly even with just 5 hours of sleep at night. Some may need up to 10 hours to give their 100 percent throughout the day.

Older people need to sleep as much as adults. They are often deprived of the right amount of sleep that they should be getting. As you age the neurons responsible for regulating your sleep patterns slowly die off. This causes to get up from sleep even if you are not properly rested. Also, the occurrence of insomnia increases with age. It makes you fall harder to fall asleep as you age.

Understanding If You Had Proper Sleep

You can belong to the group who requires 5 hours of sleep every night or else you can belong to the group who needs 10 hours of sleep to function properly. To understand how many hours of sleep your body needs you need to examine your activities properly. See if you feel lethargic and lazy throughout the day. see if you feel inactive and drowsy during the daytime. If this is the case, then you need to sleep for more hours during the night.

Also, if you are falling asleep within five minutes after lying on your bed, it shows a sign that you are deprived of sleep. See if you wake up before your alarm and feel fully rested. If this is the case, then you are getting more sleep that you require. Another sign for getting more sleep than required is when you take too long to fall asleep.

Consequences of Sleep Deprivation

Sleep deprivation can only be fulfilled by having more sleep. you can’t recover your sleep by 100 percent. Only one-third to one-half of lost sleep is recovered.

You have to understand that you can’t just cut down on your sleeping time because it doesn’t fit your schedule. If you do so, you will have to suffer in the long-run.

People who sleep for eight hours on an average have a lower mortality rate than people who sleep more or less than eight hours. Improper sleep can cause depression and weight gain, as well as poorer immune system and memory function. Studies show that sleep deprivation negatively affects cognitive skills of people.
