Heatstroke could follow prolonged activity.Keep in mind the heat index values are meant for areas in shade and with light wind. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', gives a temperature feeling by integrating air temperature and humidity. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
