10 Myths About Sleeping
- Just having uninterrupted sleep means sleeping well
In fact, no one sleeps through the night. On the contrary, even the best sleepers wake up about 30 times during the night. It’s just that these waking moments are so short that we’re not aware of them, and that doesn’t interfere with sleep at all. The problem arises precisely when we start to notice these moments and we can’t sleep again.
- Adults need five or less hours of sleep
There are many people who claim to feel good with five hours of sleep, but this is, according to scholars, one of the most problematic myths. Research indicates that sleeping five or less hours a night has harmful consequences for health, being associated with an increase in the occurrence of cardiovascular diseases and early mortality.
- The brain rests during sleep
This is the time when the whole body works to maintain its natural functions, that is, at each stage of sleep, one part of the body works more than the other. Sleep is neurologically agitated, divided into four stages that succeed and repeat during the night.
- Sleeping before midnight provides healthy sleep
It’s not the bedroom clock that best defines the ideal time for you to sleep, but your biological clock. And if you believe this myth, you will be surprised to learn that “biological midnight” (time of lowest biological yield) corresponds, for most people, to the time between three and four in the morning.
- The brain and body can adapt to less sleep
There is a tendency to believe that the body can adapt and learn to function with less sleep, but this notion is nothing more than a myth. The explanation lies in the aforementioned stages of sleep. It is necessary to go through all the stages so that there is a total recovery, in addition, it is during the last stages that the deepest and most restorative sleep takes place.
- Watching TV helps you fall asleep
Many people are surprised when they discover that television actually interferes with the quality of sleep. TV lights and noise reach the brain even during sleep and prevent it from reaching its deepest stages.
- Drinking alcohol before bed helps
Alcohol can effectively help you fall asleep, but that’s the only benefit. Contrary to what one might think, alcoholic beverages leave individuals in the lightest stages of sleep, drastically reducing the quality of rest at night.
- Sleep is a period of rest
Virtually all people change positions dozens of times during the night – not even the head remains still. The truth is that the body does not turn off during sleep, it just changes its “mode of operation”. Several important brain and body functions take place during sleep.
- It doesn’t matter what time of day you sleep
Not having a regular sleep schedule can negatively affect your health. If the internal clock is not in tune with the external world, there is a tendency for the person to feel disoriented and sleepy. Going to sleep and waking up at the same time always helps to control the so-called biological clock of the body, with benefits in hormonal control, body temperature, food, etc.
- Elderly people sleep more than young people
What happens is that the sleep of the elderly suffers changes and they sleep less during the night. Thus, it is necessary to compensate during the day.
