The latest study published in The Lancet Planetary Health says that researchers from the University of North Carolina in the US noted that heat during the night can disrupt the normal sleep cycle of sleep. Researchers say that less sleep can damage the immune system and increase the risk of heart disease, chronic diseases, inflammation and mental health conditions.
According to PTI, the study found that the average intensity of hot night events in 28 cities in East Asia will nearly double from 20.4°C to 39.7°C by 2090, increasing the risk of illness due to extreme heat that disrupts normal sleep. The burden will increase.
The results of the study suggest that the mortality burden may be significantly higher than expected for an increase in mean daily temperature. The results suggest that warming from climate change could be a problem, despite the restrictions of the Paris climate agreement. The aim of the agreement is to limit global warming to below 2 °C compared to pre-industrial levels.
Study co-author Yuqiang Zhang, a climate scientist at the University of North Carolina, said: “The risks of rising temperatures at night were often neglected. However, in our study, we found that the incidence of Hot Night Access (HNE) is daily. A more rapid than average temperature change is projected.”
Researchers estimated death rates due to extreme heat in 28 cities in China, South Korea and Japan between 1980 and 2015 and applied it to two climate change modeling scenarios, aligned with carbon-reduction scenarios adapted by the respective national governments. Were. The team was able to predict that between 2016 and 2100, the risk of death from extremely hot nights would increase nearly six-fold. This prediction is much higher than the risk of mortality from daily average warming suggested by climate change models.
