Staying safe in high temperatures

Safety tips from the Environmental Health and Safety office at UC Irvine:

Drink water: Drinking plenty of water frequently is vital for those exposed to heat. An individual may produce as much as 2 to 3 gallons of sweat per day. To replenish that fluid you should drink 3 to 4 cups of water every hour.
Take breaks: Taking breaks in a cool shaded area and allowing time for recovery from the heat during the day are effective ways to avoid heat-related illness.
Avoid some beverages: Avoid or limit the use of alcohol and caffeine during periods of extreme heat. Both dehydrate the body.
Stop and rest: If you start to feel symptoms such as nausea, dizziness, weakness or unusual fatigue, rest in a cool shaded area. If symptoms persist or worsen seek immediate medical attention.
Clothing: Whenever possible, wear clothing that provides protection from the sun but allows airflow to the body. Protect your head and shade your eyes when outdoors.
Be prepared: When in the heat be sure to pay extra attention to those you’re with and be sure you know how to call for medical attention.
