If in the morning you stay in closed spaces with poor lighting , when night comes it will cost you much more work to fall asleep. This is the conclusion reached by Mariana Figueiro and her colleagues from the Rensselaer Polytechnic Institute (USA) in a study published in the journal 'Neuroendocrinology Letters'. Specifically, his work, carried out with adolescents, reveals that when subjects are not exposed to daylight for 5 consecutive days, they experience a 30-minute delay in the secretion of melatonin , the sleep hormone that tells the body that it has arrived. time to go to sleep. In other words, each day that passes without receiving natural light in the early hours of the day supposes a delay of 6 minutes in the time at which we can fall asleep.
In addition to disrupting the biological rhythm, changing sleep patterns, body temperature and appetite, the absence of light during the day can reduce attention and performance.
The situation would change drastically, according to the researchers, if schools and offices allowed natural light to enter their rooms, where people study or work.
