LITTLE ROCK, Ark. – The National Weather Service has issued a HEAT ADVISORY for much of Arkansas through Thursday. The combination of high temperatures in the low to mid 90s and high humidity will lead to maximum Heat Indices of 105° to 110° during the afternoon and early evening hours.
Heat and Health
High heat indices as a result of heat and humidity can have serious impacts to one’s health.
Our bodies get hot, and we begin to sweat as a result of our bodies trying to cool down. Evaporation is a cooling process, so if the sweat cannot evaporate, the body won’t regulate its temperature. When humid air is present, it’s harder for the moisture on one’s body to evaporate because the air is already saturated. Therefore, the human body will feel warmer in humid conditions because less evaporative cooling is taking place.
As the body temperature rises, you could experience a heat related illness. Knowing the symptoms assosciated with each illness will help you determine which actions to take to alleviate the situation.
The Centers for Disease Control (CDC) provides warning signs and symptoms as well as recommended first aid steps for heat related illnesses, below.
- Symptoms: feeling faint or dizzy, excessive sweating, skin that may be cool, pale or clammy, nausea or vomiting, a rapid or weak pulse and/or muscle cramps.
- First aid actions: get to a cooler, air conditioned place. Drink water if conscious. Take a cool shower or use a cool compress.
- Symptoms: throbbing headache, no sweating, a body temperature above 103 degrees, red, hot or dry skin, nausea or vomiting, a rapid or strong pulse, and/or loss of consciousness.
- First aid actions: call 9-1-1 immediately and cool down as best as you can until help arrives.
Tips to help you beat the heat:
- Avoid strenuous activities, especially during the midday hours.
- Wear light colored and loose fitting clothing.
