There is an excessive heat warning in effect for Los Angeles County from 8:40 a.m. today through 8 p.m. Wednesday, according to the National Weather Service website.

A high surf advisory has also been issued for the Los Angeles County and Ventura County coasts from 2:06 p.m. today through 11 p.m. Wednesday, Aug. 25.

In spite of the high temperatures, there are precautions students can take to stay safe.

“Prevention of heat-related illness is the key,” said Dr. Yolanda Reid-Chassiakos, director and medical chief of staff at the Klotz Student Health Center, in an e-mail interview.

Students are advised to increase their liquid intake, even if they do not feel thirsty, unless they have a medical condition that requires them to limit their fluids, Reid-Chassiakos said. Drinks containing caffeine, alcohol, or excessive sugar should be avoided because they increase water loss.

Students should also stay inside during the hottest parts of the day.

“Fans help a little, but when it’s very hot, taking a cool shower or finding an air-conditioned room or building is a better option,” she said.

In addition, students can wear light colored clothing and sunglasses, and use sunscreen with UVA/UVB of SPF 15 or higher. Hats and umbrellas can also be used to keep cool.

Exercising outside should be avoided during the hottest parts of the day.

“If you start to feel ill, seek out a cool place and ask for help,” Reid-Chassiakos said.
