Pressing the snooze button on the alarm or the cell repeatedly causes a "cardiovascular attack" on the body and abuses the nervous system, as warned by a distinguished neuroscientist.
Professor Matthew Walker, who teaches at the Center for Human Sleep Science at the University of California, has some tips for people struggling to sleep, revealing that 39% of people sleep less than seven hours each night.
Sleep for less than six or seven hours a night has been associated with a multitude of health problems, such as depression, Alzheimer's disease, and anxiety. Not to mention the numerous studies linking sleep deprivation to weight gain.
Aside from stopping snooze, Walker also advises not to take a nap during the day and not to drink coffee, even caffeine, if we suffer from insomnia.
Since caffeine inactivates the chemical in the brain that helps us sleep - adenosine - the professor advises not to take caffeine after dinner, explaining that more than half of the caffeine content remains in your brain for hours after drinking coffee.
He added that caffeine-free coffee is not much better, as it usually contains up to one-third of the caffeine dose compared to regular coffee - which means that three cups of caffeine-free coffee are just as damaging to sleep as a regular.
As for the siesta? It reflects a "biphasic" sleep that mimics the model of a Kenya hunter-gatherer breed, as Walker explains, according to which people combine seven hours of sleep at night with a 30-60 minute sleep during the day. Walker explains that while siesta can for some time enhance alertness, he cannot support long-term complex cognitive functions - such as decision-making and emotional stability.
However, snooze on the alarm clock may be the worst enemy in terms of sleep deprivation, as Walker explains: "The sudden awakening from the sound made by the alarm is bad enough - the use of snooze means that we repeatedly cause this cardiovascular attack again and again within a short time. "
If you use an alarm clock, the teacher suggests that you deactivate the snooze function and adapt to the wake up at the first stroke.
