Far from what we think, when we sleep our body does not stop. You know what happens in that hour? You’ll sorprender.7 interesting things your body when you’re asleep




One of the main requirements that our body is to sleep every day at least 8 hours. During sleep the body repairs and renews his energies to take on a new journey with the best physical and mental disposition.

What few know is that, just in this period, some interesting actions that influence the quality and health in general are performed.

If you are someone who thought sleeping all activities of the body off to rest, you’re sadly mistaken. Although we are not aware of it at times, the body remains synchronized with their functions and performs pretty strange tasks.

Here we reveal all those things that happens when you manage to reconcile a deep sleep. You’ll be surprised!

1. Increases eye movements

Increases eye movements

It is estimated that during the sleep cycle we go through five stages, the last the deepest of all being. This is known as the phase of REM (Rapid Eye Movement, or Rapid Eye Movement) and is characterized by a continuous movement of the eyes back and forth, which is not in memory upon waking.

3. Delay in the kidneys

During the working day the kidneys work to filter toxins in the blood and produce urine.

It is something that happens on a regular basis and should not be cause for concern. What happens is that the brain is being organized for the changes you make in this cycle and sometimes interpreted as a fall.

The phenomenon is known as a hypnotic pulse and only happens during the rest period.
