Experts from the University of Copenhagen conducted a study on the effects of street temperature on sleep.
scientists used information from the bracelets to track sleep. Physiologists analyzed more than 7 million dream records of 47,000 people from 68 countries.
At the end of the work, the researchers concluded that sleep is disturbed when the temperature is above average. Sleep is shortened by 14 minutes. This is associated with a delay in falling asleep and waking up early in warm weather.
In underdeveloped countries, this problem is more acute than in developed countries. According to scientists, due to the lack of air conditioning. By 2099, global warming will cause a person to lose 50-58 hours of sleep each year.
