A recent scientific study: Higher temperatures at night increase the death rate

London-Sana

A recent scientific study revealed that the risk of death from extremely hot nights due to climate change may increase by about 60 percent, and that high temperatures at night disrupt the physiology of the human body.

The study, whose results were published in the British medical journal The Lancet, found that the frequency and average intensity of hot nights will increase by more than 30 percent and 60 percent by the twenty-first century, respectively, compared with an increase of less than 20 daily temperatures.

The study indicated that the average intensity of nighttime hot events will nearly double by 2090 from 20.4°C to 39.7°C across 28 East Asian cities, increasing the disease burden due to excessive heat that disrupts normal sleep.

On the other hand, researchers from the University of North Carolina in the United States noted that ambient heat during the night may interrupt the normal physiology of sleep, explaining that lack of sleep can then lead to damage to the immune system and increased risks of cardiovascular disease, chronic diseases, inflammation and mental health diseases.

The researchers found that regional differences in temperature were responsible for many of the differences in nighttime temperatures, and regions with the lowest average temperatures were expected to have the greatest potential for climate change-induced warming.
