Rising nighttime temperatures may increase the mortality rate worldwide by up to 60% by the end of the century, according to a study whose authors say is the first research to estimate the impact of hotter nights on climate change-related mortality risks.
More heat at night can disrupt sleep patterns as the body attempts to cool down, leading to adverse effects on the immune system. This could contribute to the probability of developing cardiovascular disease, chronic illnesses, inflammation and mental health challenges, the authors of the study concluded.
