Persistent activity may culminate in heatstroke.Heat index guidelines indicate values are for light wind scenarios and shaded regions. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
