5 Amazing Impacts of Eight Hours Sleep on Our Body

By | October 26, 2020

The younger generation of the 21st century is career-oriented. They are ready to compromise with their health for their career. However, research suggests that sleep deprivation may lead to multiple diseases. A healthy individual needs seven to eight hours of sleep daily. While a person sleeps, the human body sends several signals to the brain for releasing certain hormones. The hormones help in

  • Strengthening memory
  • Controlling hunger pangs
  • Boosting up immunity
  • decreasing risk for health conditions

However, sleeping for more than eight hours at a stretch may harm the body.

So, let us find out why doctors recommend seven to eight hours of sleep daily for individuals.


Affects lifespan

Many people sleep for five to six hours on an average per day. Scientists in the United Kingdom have revealed that people who slept for less than five hours per day had twelve percent more chances of dying prematurely. On the other hand, people who sleep for more than nine hours per day had thirty percent higher premature death chances.

This information has been the fruit of research conducted over twenty-five years.

Controls hunger

Sleep-deprived people need more energy to sustain themselves. Usually, the human body needs lesser movement and calories than average at night. However, in sleep-deprived people, the body releases chemicals to the brain, signalling hunger at night. As a result, people who sleep for less than eight hours per day experience hunger pangs at night. They eat more but exercise less. This leads to a drastic weight gain.

Controls hunger

Sleep deprivation is a significant cause of concern in children too. They are also worried about not doing up to the mark in their studies and career to sleeplessness. A research conducted in 2014 suggested that children who slept less were significantly more prone to high BMI and obesity. Such problems increased as they grew older.

Sleep affects immunity

The immune system of humans releases a compound called cytokines when they sleep. Specific cytokines protect the immune system. They combat inflammation, particularly inflammation caused by infection.

In the case of sleep-deprived people, sufficient cytokines are not produced to protect their immunity. The white blood corpuscles and specific antibodies may also take a dip if they sleep for less than seven or eight hours per day.

Sleep affects immunity

A research conducted in 2013 suggested that people who slept less than seven to eight hours each day faced a spike in their bodies’ inflammatory compounds. These compounds trigger different types of allergies and asthma. Sleep deprivation for long and short periods are equally harmful to the body.

Sleep impacts memory

Sleeping for regular hours helps strengthen memory. People who sleep for seven to eight hours after learning something can retain their knowledge. Those who are sleep-deprived face difficulty in accessing incidents that happened a long time ago.

Their brain is so overworked and tired that they face trouble in receiving information. Even if they receive information, they process it differently. Seven-eight hours of sleep boosts creative thinking and long-term memory.

Protects against diseases

The chronic sleeping disorder leads to several health issues. The work-life balance goes in for a toss. People who do not sleep for seven to eight hours per day are prone to diseases like obesity and heart diseases. A lack of proper sleep may also lead to obstructive slee apnea.

Factors like low work-life balance, stress, and tension affect the hours for which a person sleeps. These factors may trigger inflammation and other health problems, apart from a sleeping disorder.
