A photo from open sources Smartphones that modern people don’t part even in the bedroom, can cause problems with excess weight, warn Spanish researchers. According to them, the human body needs pitch darkness in order to produce the necessary amount of hormones involved in the regulation turning food and drink into energy. That means scattered light from street lamps can disrupt the release of melatonin and prevent the effective digestion of food. But scientists say that the shortwave blue light that some of modern devices is the most damaging to sleep and, hence metabolism. Although this light is not bright enough to illuminate the whole room, he is still able to harm to the human body, says a team of scientists from the University Granada in Spain. They found that melatonin injections helped obese and diabetes rats, regulate internal body systems. Currently specialists in Manchester University students are studying how normalizing sleep can help patients who already suffer from diabetes – a disease often associated with obese. Dr. Simon Kyle, a sleep researcher at the university, said: “Many people are interested in this at the moment, given that sleep periods are reduced and people expose themselves exposed to artificial light at night. “According to the scientist, he and the team were interested in how the change in structure “wakeful sleep” may be due to diabetes and obesity. “There are many studies showing that with the onset of darkness increases the content of melatonin and humans falls asleep. When the sun rises – the concentration of melatonin declining. This alternation of “light-dark” favorably affects our body, “says Kyle. When periods of sleep are shortened or this time a person is exposed to light, broken melatonin secretion, and this can cause changes in metabolism substances. Blue light is the most destructive because it interferes with the consciousness of “disconnecting,” the scientist added. Earlier this year leading scientists from the universities of Oxford, Cambridge and Harvard, warned that lack of sleep can cause serious problems with health, causing diseases such as cancer, heart disease, type 2 diabetes and obesity because it knocks down the biological clock. They said that this problem became especially relevant in the light of popularizing all kinds of gadgets that people do not part with until late in the evening and which emit blue light. Dr. Kyle advised turning off smartphones, tablets and desktop computers a couple of hours before bedtime to reduce exposure artificial light. “If you can achieve complete darkness in night time, you can recreate the pre-industrial time period and thereby reduce the risk of developing not only obesity, but the whole a number of other health problems, “concluded the scientist.
