We spend about a third of our lives in sleep, which remains as important as eating, drinking, and breathing. It is not only a “negative comfort”, as the scientific term says, but much more, it is also a kind of biological energy saving situation. When we sleep, we consume less body energy than vigilance, and scientists have yet to find the full truth behind the need for sleep, although many studies suggest that the brain is responsible for our need to sleep.

Everyday life has become full of responsibilities and events that have made everyone busy to meet their requirements, and with the pace of daily life and busy work, we may not find time to get enough rest and sleep.

what happens if you do not get enough sleep?

The keys to happiness are many, the most important of which is the preservation of physical and mental health, especially concerning your daily lifestyle, including sleeping hours. The rapid change in the lifestyle of individuals in recent decades has led to profound transformations that touched various aspects of human life.

However, some sleep for eight hours a day and still feel tired of continuing to examine the reasons for this, because the background of this fatigue may be symptoms of serious diseases. Know her, doctors and health experts recommend sleeping for at least eight hours a day. But some people go to sleep early and sleep up to ten hours a day or more and yet feel tired and tired and show signs of stress the next morning.

According to studies published in this area, these disorders, which vary according to different people and age groups, in particular, insomnia and sleep apnea of ​​breathing and moving some parts of the body during sleep, sleep for long hours, and partly awake during sleep.

Studies suggest that shortages of this biological need during medium-term periods may lead to a decline in production and increase the speed of irritation of nerves, disorder, memory impairment, lack of concentration and depression, while lack of sleep over the long term seriously harmful to human health. If the long journey to treat these disorders begins with a diagnosis by a specialist doctor, a return to normal, especially in adults, often includes, as well as taking medications, substantial changes in lifestyle.

According to Stephen McGregor, founder of the Barcelona Leadership Academy and an expert on health, sleep is a “basic skill” that one should learn and practice, adding that sleep is “an activity that must be a daily priority.”

What exactly happens in our heads during sleep?

positive results that help to feel focused, and improve human performance without adversely affecting sleep during the night, experts advise that the human sleep seven and a half hours a day until his death and see that this is the rate of healthy sleep.

Sleep is necessary for the process of psychological renewal of the human being, it is known that man “spend about a third of his life sleep,” but this third is necessary for his survival, Sleep is essential to the process of psychological renewal of the human being; it can suffer serious health damage if this process does not occur.

What is the difference between bad sleep and insomnia? To face at night some of the difficulties that prevent the immortality to sleep normally is not a problem in itself, as an emergency. However, if these difficulties occur three times a week and for more than three months, experts consider this as a sleepiness disorder or sleep disturbances / if they coincide with the feeling of fatigue during the day and lead to shorten the human role and social role.

Why do people need to sleep?

“At night, many processes start inside the brain, which is more during sleep than at any other time in our lives,” says Albrecht Forster, a neuroscientist at the University of Tübingen. When we sleep, reconstruction and arrangement begins. “Sleep is something like washing, cutting and arranging in the brain,” Forster told the German website Spectrum.

Arranging memories


Sleep also plays an important role in redistributing and stabilizing our memory. Sleep reorganizes the content of our memory information and turns it into high-quality knowledge. “Most of the memories are supposed to be on hand while you sleep,” Forster says. How is that? During sleep there is an active exchange between different areas of the brain: the hippocampus, which is somewhat the notepad in our brain, observes any important experiments and gives during the sleep the cerebral cortex pulses to display them again and again and install them and link them together.

During this storage process, our memory is very weak, so new experiments may not interfere with it.

That’s why we’re losing consciousness in our sleep,” Forster says, adding that “formatting a hard drive only works if you stop giving new prompts.”

An important balance


Sleep plays a key role in the functioning of the brain, ensuring that the system works best and that the brain is not out of balance. “It seems that awakening is increasingly putting the body in a physical imbalance,” Forster says. Without sleep, the relationship between our nerve cells is unbalanced, as is the amount of neurotransmitters, which are the neurotransmitters that are released to transmit signals between neurons.

Imbalance affects not only our thinking but also our mood. We are emotionally imbalanced because we lack the exact control that can only be achieved through sleep. The importance of sleep processes is obvious when they don’t work properly. If the brain does not get rid of protein deposits, it will accumulate, overlap and kill neurons. Scientists have found such protein accumulations in the brains of people with neurodegenerative diseases such as Alzheimer’s disease and Parkson.

Sleep is the best medicine


The body also needs to sleep to regenerate everything in it. For example, repair and growth of cells increases at night. Comfortable sleep also maintains the balance of blood sugar and metabolism of our fats and restricts our appetite. Those who work regularly in night shifts are at greater risk of developing type 2 diabetes, obesity, and cardiovascular disease.

By the way, sleep also affects the strength of our immune system. When we sleep, the immune cells prepare for the next day and share information about extraneous viruses to form the basis of immune memory. When the body infects the intruder virus itself twice, the second time the immune cells respond faster and more efficiently than the first time.

Sleep may be an “indispensable evil” for some people who continue to work day and night, but the truth is that it remains a necessary part of our lives. When we don’t sleep, we lose half of our lives, perhaps our entire lives.

How does evening exercise affect sleep and appetite?


Exercise is a positive and healthy thing, but what is the most appropriate period to exercise?

Does evening exercise negatively affect human sleep and diet?

A study specialist answers these questions.

A recent study by Australian researchers shows that exercising in the evening affects appetite. The study found that those who exercise at night eat less, according to the German site “Focus”. The study, which results in published in the magazine ‘Experimental Physiology’, eleven men who did intense exercise at intervals for 30 Minutes in the morning, afternoon and evening. Participants in the study were on average 49 years old, obese and non-smokers and not very active, also, they did not suffer before from any sleep disorders or metabolic disorders, according to the site “Fit for Van” German.
