She noted that the negative effects of sleeping in high temperatures for healthy individuals include feeling tired throughout the day, irritation by seemingly trivial external factors, and exhaustion.

"What can we do for a good sleep during the 'Red Code Heatwave'? We try to maintain strict sleep hygiene; avoid napping, which can worsen insomnia; dress appropriately in light clothes that absorb sweat; try to create an optimal temperature in the bedroom, remembering to adjust air humidity as well - if you don't have a fan, try filling a bottle with ice-cold liquid to lower the temperature in the bed, or alternatively use cooling socks (wet or kept cold), cooling your feet lowers the overall skin and body temperature; stay well-hydrated, even at night; try to stay calm, as irritation and nervousness overtax the body already affected by high temperatures; don’t forget about the children and the elderly around you, who are much more fragile," are the tips provided by the physician, according to the Facebook page of the "Marius Nasta" Institute of Pneumophthisiology.

According to her, normally our body temperature tends to drop slightly 1-2 hours before bedtime, which helps us fall asleep more easily and have deeper sleep.

"In essence, when it's very hot, REM sleep, the dream sleep that helps reset our body for a new day, strengthen the immune system, and process memories and emotions, is affected," says Beatrice Mahler.

She points out that high ambient temperatures significantly hinder the body's self-regulation of temperature, directly affect sleep quality, increase respiratory rate, heart rate, and skin moisture in an attempt to cool the body, and, last but not least, induce a state of irritability in the body.

"Thus, even if we fall asleep just as easily, because the high daytime temperatures deplete the body's energy, sleep is frequently interrupted and shorter. Repeated awakenings are due either to excessive sweating or the dry air in the room," the physician mentions.

The negative effects of sleeping in high temperatures translate for healthy people into feeling tired throughout the day, irritation by seemingly trivial external factors, and exhaustion, she warns.

"Patients with chronic diseases, including chronic respiratory conditions, associate inefficient sleep with the risk of acute exacerbations of chronic diseases due to acute infections, through the direct effect of polluted particles in the inhaled air, such as ozone, which increases in cities with heavy traffic especially during heatwaves," adds Dr. Beatrice Mahler.
