There are only some things that literally cannot live and one of them sleeps, all living organisms sleep, even plants and bacteria. People sleep almost a third of their lives. We cannot avoid it because it is important for life since our body must restore itself, rejuvenate, build muscles, repair tissues and synthesize hormones. Say no to plagiarism.

Another discovery is that humans sleep more than any other species. One of the reasons for this is survival and since we are at the top of the food chain so we can hit it and relax but for other lower species it is not possible to not be aware of it at any time. According to animalogic, the giraffe is one of them. animals that sleep little “With their long imposing necks, sleeping is not the easiest activity for giraffes. Getting up from lying down can take precious seconds and leave them incredibly vulnerable to predators like lions and crocodiles. Dreaming gives the body rest and allows it to prepare for the next day. It's like giving the body a little vacation. Sleeping also gives the brain the ability to solve problems. Scientists aren't sure what kind of organization the brain does while we sleep, but they think sleep may be the time when the brain classifies and stores information, replaces chemicals, and solves problems. Therefore, after learning something and sleeping, the person may have more memory on the subject. The amount of sleep a person needs depends a lot on their age. The National Sleep Foundation lists the times for all age groups that a person should sleep: newborns: sleep range of 14 to 17 hours per day, infants: sleep range of 12 to 15 hours, toddlers: small: sleep range 11-14 hours, preschoolers: sleep range. 10-13 hours, school-age children: sleep range 9-11 hours, adolescents: sleep range 8-10 hours, young adults: sleep range 7-9 hours, adults: sleep range 7-9 hours, elderly: sleep range 7. -8 hours.

We don't know exactly what happens when we sleep, all we know are the effects of sleep. However, healthy sleep proves that scientists have proposed 4 theories about what happens when we sleep: inactivity theory, energy conservation theory, restoration theory, and plasticity theory cerebral. The inactivity theory was the adaptation of sleeping animals once they were safe from their predators. The main goal of energy conservation theory is to save energy when it is less needed, such as at night. According to the healthy sleep article, the most reasonable theory is its restorative theory where many things happen "like muscle growth, tissue repair, synthesis of.
