The participants in the experiment had air temperature and humidity sensors installed in their bedrooms and wore the ring-shaped device during the night.
Scientists conducted a study with a group of 50 volunteers and found that the optimal temperature range for quality sleep for people of age is 20-25°C.
About it informs Science Alert portal.
For the study, people aged 65+ living in Boston (USA) were selected.
The participants had air temperature and humidity sensors installed in their bedrooms and wore a ring-shaped device throughout the night to track sleep, skin temperature, heart rate and movement. People lived in a variety of accommodations, from small state-subsidized apartments to private single-family homes.
Scientists believe that a 10 percent decrease in sleep efficiency is enough to impair brain function, increase stress, anxiety and fatigue, and affect blood sugar control the next day.
As the planet warms, the nights are getting hotter, and scientists predict that by 2099, high temperatures could reduce the number of hours a person sleeps per year by about 50 hours. At the same time, the elderly are among the most vulnerable to heat stress both during the day and at night.
When the temperature rises to 30 degrees, sleep efficiency drops by 10 percent, scientists noted. They believe that for quality sleep, you need to improve airflow and choose light clothing for sleep. Improving the thermal comfort of the building itself could have a greater effect, although it is more difficult and expensive, the researchers noted.
As Cursor reported, doctors have named a healthy drink that will help you fall asleep and strengthen your sleep.
Previously, the Cursor informed about why prolonged sleep is dangerous to health.
