long sleep deprivation

On average, an adult needs a minimum of 8 hours of sleep a day. However, due to our hectic life, many of us only sleep 5-6 hours.

According to experts, long sleep deprivation can lead to serious health problems such as a malfunctioning cardiovascular system, obesity, and diabetes.

Nonetheless, it is very common that people stay awake for an extreme amount of time, and this, for several days in a row.

Long sleep deprivation: Why is it dangerous?

According to researchers, the longer a person goes without sleep, the more changes occur in his body.

It is important to note that each person reacts to sleep deprivation differently. In fact, it depends on their age and health.

But in any case, at the initial stage of sleep deprivation, the usual symptoms of lack of sleep occur:

  • tiredness and drowsiness
  • deterioration in concentration and memory
  • irritability
  • increased appetite
  • weakening of immunity

The longer a person does not sleep, the more these symptoms manifest themselves.

A day without sleep

If a person does not sleep for 24 hours, the first organ to be affected is the brain. Initially it will start to conserve energy by turning off some neurons, which leads to drowsiness, irritability and impaired thinking.

Researchers explained that long sleep deprivation is comparable to alcohol intoxication.

Generally, lack of sleep drops the body temperature and raise the level of the stress hormone cortisol. This is why people with sleep deprivation tends to be in bad mood.

Moreover it causes confusion in the body and it begins to incorrectly produce hormones to regulate appetite as well as the immune function.

Two days without sleep

According to a scientific research, being deprived from sleep for 30 hours makes a person ceases to recognize the emotions of other people.

This is because the brain is trying to save energy by further turning off neurons. At this stage, a person begins to enter a state of so-called microsleep lasting several seconds. In other words, he is literally losing consciousness.
