Exposure time in extreme heat depends on factors like individual health, hydration, activity level, and humidity. For example, a healthy, hydrated individual resting in the shade might tolerate higher temperatures for a longer period than someone engaged in strenuous physical activity in direct sunlight. Ultimately, exceeding safe exposure limits can lead to heat-related illnesses ranging from mild heat cramps to life-threatening heatstroke.
Understanding the limits of heat exposure is crucial for protecting individual well-being. Historically, communities in hot climates have developed strategies for managing heat stress, including architectural adaptations and cultural practices emphasizing rest during the hottest parts of the day. Today, public health campaigns emphasize similar principles to prevent heat-related illness, particularly during heat waves.
