Note: The heat index, also known as 'feels like' or 'apparent temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
