The intensification of heat stress poses significant risks to human health, particularly in regions already experiencing high temperatures. Prolonged exposure to extreme heat can lead to heat-related illnesses, reduced labor productivity, and increased mortality rates. Vulnerable populations, including the elderly, children, and those with pre-existing health conditions, are at heightened risk. The study also highlights the growing challenge of nocturnal heat stress, which limits recovery during sleep and exacerbates health risks. Urban areas, due to heat island effects, may face even greater impacts. Additionally, the expanding heat stress season could disrupt agricultural cycles and strain energy resources.
