Reasons for sudden summer insomnia revealed

Cardiologist and somnologist of the medical center "SM-Clinic" Natalia Zolotareva explained the causes of sudden sleep problems that many people experience during the summer period. The specialist shared her observations with the publication "Lenta.ru".

According to the expert, the main factor provoking insomnia in summer is the disruption of the body's thermoregulation. "The human brain needs to lower the internal body temperature by approximately 0.5-1 degree to enter deep sleep. A hot environment interferes with this natural cooling process. The body simply cannot 'shed' excess heat, and sleep becomes shallow and interrupted," explained Zolotareva.

The Russian medical professional also noted that summer insomnia can be caused by hormonal imbalance.

"The sleep hormone melatonin is better produced in cool and dark conditions, while stuffy summer nights, especially in the city where it's still bright from streetlights even at midnight, suppress its production. With a lack of melatonin, the brain doesn't receive a clear signal that 'it's time to sleep'," emphasized Natalia Zolotareva.

The somnologist added that the increased duration of daylight also negatively affects sleep quality by disrupting the body's circadian rhythms. Additionally, the physical discomfort from heat itself can become a serious obstacle to full relaxation and falling asleep.
