Heat index

April's mean heat index is evaluated at a fiery hot 38°C (100.4°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. 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 extremely significant for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
