Sweltering Nighttime Temps May Increase Global Mortality

A new study in The Lancet Planetary Health is the first to estimate the impact of hotter nights on climate change-related deaths. (see study here) The researchers find that rising nighttime temps may increase the global mortality rate by up to 60% by the end of the century, if nothing is done to curb climate pollution and its impacts. Hotter nights can disrupt sleep patterns as the body attempts to cool down, leading to adverse immune system responses and a higher probability of cardiovascular disease, chronic illnesses, inflammation and mental health challenges. Researchers warn vulnerable and low-income people are more likely to be at risk as the average intensity of hot nights nearly doubles by 2090 across 28 cities in east Asia.
