Many nights without sleep can be the gateway to the disease considered the disease of the century

After a night spent tossing and turning in bed with insomnia, many people expect to wake up in a bad mood and tired. However, the problem – of one or more nights of inadequate sleep – can be the gateway to the disease considered the disease of the century: depression. Researchers from University College London they concluded that sleeping less than five hours can significantly affect mental health.




Research published in the scientific journal Nature shows that people who sleep little are more likely to develop depression. 7,240 individuals, who are, on average, 60 years old, were analyzed.

Another study, conducted in the United States, also draws this parallel between poor sleep and bad mood. “We found that all forms of sleep loss – total sleep deprivation, partial sleep loss, and sleep fragmentation – result in emotional changes. The strongest and most consistent effect is that sleep loss reduces positive mood.”He said Dear Palmerdirector of the Sleep and Development Laboratory at Montana State University in Bozeman.

“We also found that sleep loss increases feelings of anxiety,” the researcher said. “When experiencing emotional events, people were also more likely to report different reactions than people who were well-rested.”

According to the World Health Organization, the disease affects more than 300 million people of all ages worldwide. In Brazil, the estimate is that 5.8% of the population is affected by the disease.
