It is easier to sleep after sex

According to research published in the National Center for Biotechnology Information , having sex before bed also influences the quality of your sleep.

Through the study it was possible to see that the affective contact with the partner can cause the brain to release some substances capable of causing a pleasant and well-being sensation, keeping you relaxed.

So, it is TRUE , sex has the potential to help you get a good night’s sleep, due to the levels of oxytocin, which rise after sex, are related to the quality of sleep.

Drinking Before Bedtime Helps

MYTH . According to the researchers, consuming alcoholic beverages before bedtime may even make you fall asleep faster, however, it is important to know that it will not be the same quality of sleep.

Screens help you sleep

By the time we have just gone to bed, turning on the TV can be like a way to get to sleep.

But depending on the type of content you watch, it can really interfere with falling asleep, that is, MYTH .

For example, a horror or action movie, where the noise noises oscillate with the intention of scaring or creating a moment of suspense, may be able to send your sleep away and make you nervous or tense.

But those who think that taking a look at social networks will not have an impact are also mistaken.

The device, like most devices (TV, tablet or computer) emits the so-called blue light, which stimulates the brain to remain active longer, disrupting the biological cycle of sleep.
