American scientists have found out what weather is the most difficult to sleep. Researchers from San Diego have found that the duration of sleep can reduce even the minimum nightly rise in air temperature, according to Pannochka, an online publication for girls and women aged 14 to 35.. net The study of scientists from the University of California (USA) lasted for 9 years and affected 765,000 American citizens. The study is based on data from the National Center for Environmental Information on air temperature and observations of volunteers who noted the quality of their night's sleep..

Nick Obradovic, one of the Californian researchers, reported that even a one degree rise in temperature during one night led to sleep disturbance.. Scientists have calculated that for every 100 people tested, their total number was 3 nights without sleep.. Thus, monthly temperature fluctuations can lead to 9 million sleepless nights..

Scientists believe that based on the data of the study, residents of southern countries should be more prone to bouts of insomnia.. But the answer to that, they say, will come from additional observations they plan to make in the coming years..

It is worth noting that insomnia is dangerous for a person’s physical and mental health.. With lack of sleep, the body not only becomes more vulnerable to various diseases, but also becomes irritable, anxiety and bad mood appear..
