In search of lost sleep. Because counting sheep is no longer enough

Who has not yet happened one sleepless night, to the office manager saying, “Don’t worry, nice coffee and you’ll be up and up immediately. Tonight then, please, go to bed early tonight, and you’ll make up for all the sleep I’ve lost.” Lost hours of sleep not recovered and again is the recommended eight hours of sleep necessary and sufficient?
Finally, how many hours you sleep or more importantly sleep quality?
Not everyone is fortunate enough to have a doctor who specializes in sleep disorders as their office manager. That is why we tried to hear some of them and hope that they will benefit you.

Jeweler and a bit pessimistic Claudio Vecini, The otolaryngologist, expert in sleep medicine and professor at the Universities of Bologna and Florence tells us: “Italians are sleeping increasingly worse, and the biggest problem is the perception of poor sleep quality. I sleep poorly and wake up tired.” After that, he gave a decisive boost to the poor quality. Already for a night’s rest.

Jacobo Vitale A researcher at the Galeazzi Orthopedic Institute in Milan, he focuses explicitly on the impact of the 2020 closure that “negatively affected the qualitative and quantitative parameters of sleep, especially in young students with an increase in insomnia to 15% and up to 40% in the Italian population”. Vital stresses the importance of education about the importance of sleep for our health. He recommends adopting “real sleep hygiene strategies that can act as a protective factor in social isolation.”

Those who love physical activity do not miss the warning Carlo Castagna, Professor of Exercise Science at Tor Vergata University, “An athlete can’t get better if he doesn’t recover.” Castagna reminds us that recovery cannot be reduced to simple rest. “Recovery is strategically fundamental, it focuses on the so-called internal load, that is, on the athlete’s reaction to the load managed, for example, by the sports coach. Recovery is multifactorial and attaches great importance to the correct implementation of sleep. “

And if you think sleep disturbances respect “equality of opportunity” for men and women, listen up Francesca Vitale, a researcher in psychology at the University of Verona and a sports psychologist: “Women and men sleep differently, quantitatively and qualitatively.” Due to a hormonal problem, sleep of the fair sex is often more difficult, especially in the premenstrual phase. After menopause, the differences between men and women decrease dramatically.

Vitaly recommends monitoring sleep hygiene and, from time to time, hormone levels as well as regular physical activity. “Changing one hour of lost or missed sleep can significantly reduce the ability to pay attention and focus,” he further explains, “Because we are not just a perception but also an emotion, a lack of quality sleep can lead to an increased level of anger and aggression.”

A recent study tells us what doctors and nurses need comfort At least 20 minutes during night shifts. The naps help ensure clinical quality and patient safety but not only: they help make the health worker’s journey home after the work shift more serene.
The same research by an anesthesiologist Nancy Redfern The NHS Foundation Trust from Newcastle Hospitals warns us that ‘sleep debt’ begins to accumulate after two or more nights of limited rest and recommends a recovery of at least two days of adequate sleep. Finally, from this analysis the recommendation emerges to do no more than three consecutive night shifts.

What happens to the body while it sleeps?

The feeling of being “reborn” after a good sleep corresponds to what is happening in the living organism: the body detoxifies accumulated during the day. During sleep, metabolic activity slows down and the brain, in synergy with the lymphatic system, activates to drain and expel toxic proteins produced in the waking phase.

Not only. During rest, cellular activity also focuses on itself and itself renewal. Think of the muscles that, by relaxing, repair the micro-injuries that accumulate during the day. Or for skin that undergoes a real cosmetic treatment at night: thanks to the reduced metabolic activity, the body uses proteins and enzymes that serve other purposes during the day for the benefit of the dermis. The result is an increase in production Collagendermis scaffolding that plays a critical role in maintaining the freshness and elasticity of the skin.

In addition, a study conducted by the University of Wisconsin and published in Journal of Neuroscience, Explains that during sleep, it results from the production of cells that form myelina kind of protective, insulating sheath that allows for the correct transmission of nerve impulses: This would explain why restful sleep and the right amount of rest allow us to be more clear, reactive and during the day and how, instead, sleep disturbances can get us into trouble.
