WHEN SLEEPING LITTLE DOESN'T HARM YOU

There's no honest doctor in the world who doesn't recommend getting the amount of sleep our bodies need. This number of hours varies based on theage and which on average is around seven hours a night. Something we are unable to do, with some resulting damage. However, there is some good news coming from the scientific world: some people manage to stay rested even with just a few hours of sleep. sonnoSix, even four, are enough for them. And that's because they possess genes that allow them to reinvigorate their body and brain even with a quick nap. But let's proceed in order.

Sleeping little and poorly not only prevents us from recharging our batteries but also damages our memory . This warning comes from research conducted by a team of researchers at the University of Groningen in the Netherlands, led by Dr. Peter Meerlo.

CONSEQUENCES OF SLEEP LOSS

In particular, according to researchers, losing too many hours of sleep could damage our learning ability and spatial memory over time . Sleep loss could, in fact, affect an area of ​​the brain called the "hippocampus," which is crucial for memorizing spatial-temporal data.

Regularly adapting our memories to changing conditions is essential for managing regular changes in an environment, such as commuting from a new workplace to home.

One more reason to try to lead as regular a life as possible and to devote the right number of hours of sleep to rest , an important nourishment for our body like drinking and eating.

WHAT HAPPENS IF YOU SLEEP TOO LITTLE? Here are dots after the hyphens.
 
If you sleep too little, there are some common risks that have been thoroughly explored by several studies on the topic of insomnia. In particular:
  • The hormone of the stress. and there is no time to recover energy for the next day
  • They increase “bad” cholesterol and sugar, two elements that are certainly not good for our body
  • There is a risk of disturbances in concentration, the memory and in general on attention
  • You are exposed to frequent fits of anger, with related mood swings
  • Asthenia arrives, a form of chronic fatigue.

WHAT HAPPENS IF YOU ONLY SLEEP FIVE HOURS A NIGHT?

Sleeping less than the average recommended by doctors leads to various imbalances, which have been evaluated by experts from time to time. For example, according to a study by the University of Chicago, sleeping five hours a night (two to three hours less than necessary) alters heart rate. And this increases the risk of disease. cardiovascular and be more likely to have to deal with problems of high pressure.

CAN LOST SLEEP BE RECOVERED?

Lost sleep can be made up for, as long as it's an occasional, non-chronic circumstance. Let's take an example: if we've stayed up late for a few nights and woken up early for work, or haven't been able to catch up on sleep, sonnoWe can recover those lost hours in the following days. And it will be a huge benefit for our body. But if we lose hours of sleep continuously, because we suffer from insomnia, then we won't be able to make up for the lost hours with a good night's sleep. We'll have to treat insomnia, starting with the foods that help you sleep.

GENETIC INSOMNIA

Insomnia may have a genetic component, and this has always been considered bad news. But after the release of the results of a study by the University of California at San Francisco, the relationship betweeninsomnia and genetics needs to be revised, and not a little. After ten years of studies, American researchers have managed to classify the Familial natural short sleep (Fnss), The familiar short natural sleep. Those who experience it feel as fresh as a daisy, even after just four hours of sleep.

CAN THOSE WHO SLEEP LITTLE BE RESTED?

If insomnia is genetic, those who sleep little are not only more rested than others, as they need less time to rejuvenate their brains and bodies. They also accumulate greater resilience over the course of their lives to neurodegenerative diseases, such as Parkinson's and Parkinson's disease.AlzheimerThe University of California study unequivocally demonstrates two things. First, those with a family history of short natural sleep patterns are not at increased risk of dementia. Second, shorter sleep duration, in this case, is associated with a protective effect on the body against neurodegenerative diseases. The picture is completely reversed compared to what we knew about the risks of insomnia. And everything seems to indicate that, more than quantity, the quality of sleep matters for health.
