Do you know what happens when we sleep?

Every night, almost everyone in the world enters a state of paralysis and unconsciousness. However, what really happens when our organism is turned off? What is the impact of lack of sleep?

Below we tell you what happens when we enter a state of drowsiness until we turn off completely.

Circadian Rhythm

In the brain, more exactly in the hypothalamus, dreams are controlled by the Circadian Rhythm or the so-called “body clock“.

The body’s clock responds to light patterns, allowing the production of melatonin at night and turning it off when we perceive light.

Stages of Sleep

There are four (4) states of sleep that the body experiences in cycles while sleeping.

Regular sleep cycle of 90 to 120 minutes

  • Light Sleep: Stage 1 and 2.
  • Deep Sleep: Stage 3 and 4.

On a regular night, we can go through these cycles about four or five times.

Stage 1 & 2: We go from being awake to falling asleep through this transition, which is also called Non-rapid Eye Movement (NREM).

Both, the heart rate and respiratory frequency begin to decrease. The body temperature drops. The muscles can contract.

Stage 3: Also known as “Delta Sleep” because of the brain waves that are released during sleep. This is also the first state of deep sleep in which the cells of our body work to heal and improve our muscles and bones, allowing the body to recover on its own.

Stage 4: It is at this stage that we begin to dream. It is also known as Rapid Eye Movement Sleep or REM.” Our body produces chemicals that temporarily paralyze us so that we do not act outside of our dreams.

In this state, the brain is extremely active. We can notice how people who go through this stage move their eyes below their closed eyelids as if they were awake.

Sleeping Things to Consider

Humans sleep approximately 25 to 30 years throughout our lives. That’s almost a third of regular life.

The proliferation of technology and the stress of modern life make people sleep less than they did 50 years ago.

Sleeping less than 7 hours can bring some unwanted disorders such as some chronic conditions like heart disease, obesity, diabetes, etc., which can drastically reduce our life expectancy.

For longer and healthier life, you have to learn to rest well. Take your time to recover the necessary energy, to not only work, study, or play sports, but to be in a good mood.

Research says, for example, that an extra hour of sleep can make baseball athletes have edge over their competition. So, maybe the recipe to become favorite in the odds to win the World Series might be just under the sheets.

Quality vs Quantity

It is also said, “The more you sleep the better and more energy you will have during the day”. In addition to having a better recovery of the organism, do not pay attention to everything you hear. Remember that the quality of sleep is more important than the number of hours you sleep.

The most important phase for us is the deep sleep one since – as we go through this state – our body rests and eliminates metabolic toxins from the brain that our system cannot eliminate when we are awake.

According to what we know, the first five hours of sleep are the most important. After this period, our dream becomes more superficial, diminishing its quality.

For a better night’s rest, remember to keep busy during the day, although it is not necessary to over-demand. Just try to be a little tired before going to bed. Good sleep!
