Alert: Heat cramps and heat exhaustion are likely to occur. Prolonged exertion can lead to heatstroke.
Know that the heat index computations account for shaded terrains and slight winds. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
Humidity
