THE SCIENCE OF SLEEP<\/b><\/p>\n
Sleep is one of the circadian rhythms, or variations in the body that are associated with different changes in the environment. In other words, our moments in bed represent only a part of our biological clock, a habit that is also not exclusive to humans, since other animals, and even plants, respond to light and darkness. When it gets dark, our brain secretes melatonin through the pineal gland, responsible for causing the necessary fatigue to fall asleep, while in the morning, we secrete cortisol, which helps us stay alert.<\/p>\n
Each night, we experience four to six cycles while resting, moving from wakefulness to deep sleep and then to REM sleep, which is notable for rapid eye movement. \u201cTo be complete, a sleep cycle must last approximately 90 minutes and must have<\/p>\n
a stage known as deep sleep, in which we really rest, allowing the body to regenerate and creating other benefits<\/p>\n
that we already know\u201d, points out Dr. Mariana Naranjo Bravo, academic and psychotherapist. According to the National Sleep Foundation, an American NGO with more than 30 years of experience in sleep disorders, an average adult should sleep between seven and nine hours to meet the necessary sleep cycles to have an ideal rest.<\/p>\n
However, the circadian rhythm of sleep can be altered quite easily by factors such as caffeine consumption, a large meal at night and even the screens of our electronic devices: just two hours of scrolling <\/i>on our cell phone or for a while in front of the television to unbalance the production of melatonin.<\/p>\n
