Rising nighttime temperatures impact global health and sleep

Global climate trends show a rise in nighttime temperatures, impacting human health and sleep quality. Data from the Copernicus Climate Change Service indicates that since the 1970s, the minimum temperature during the ten hottest nights of each year has increased globally by approximately 0.32°C per decade. Additionally, the frequency of “tropical nights”—where temperatures do not drop below 20°C—has increased by about two nights per decade.

High nighttime temperatures prevent the body from undergoing essential physiological recovery. During sleep, the heart rate and internal body temperature typically decrease to allow the nervous, immune, and cardiovascular systems to recover. Excessive heat forces the heart to work harder to circulate blood and can lead to dehydration through sweating, resulting in fragmented sleep and daytime fatigue.

In Albania, weather forecasts for August 25, 2026, indicate high temperatures across the country. Regions such as Tirana and Elbasan are expected to reach up to 37°C, while southern areas like Vlorë and Sarandë will see temperatures around 34°C. Northern areas, including Shkodra and Kukës, will remain slightly cooler at approximately 30°C.
