Symptoms of heat stroke, which can be caused by over-exposure to direct sunlight, are high body temperature, skin that is red and dry, rapid pulse, and loss of consciousness. Heat stroke can lead to death if untreated. An individual with any of these symptoms should see a physician as soon as possible.

Avoid heat-related illnesses:

• Drink extra fluids such as water, fruit juices or lemonade, especially during very humid weather.
• Avoid caffeine and alcohol.
• Wear lightweight, loose-fitting clothing (especially made of cotton, if possible) that does not interfere with the evaporation of perspiration.
• Eat small meals and eat more often. Decrease food high in protein, which increases metabolic heat.
• Try to engage in activities that involve strenuous labor in the evening or early morning hours to avoid the hottest part of the day, which is between 10 a.m. and 3 p.m. If possible, stay in an air-conditioned environment during this time.
• In a home that lacks air-conditioning, stay in the basement or lowest floor, close drapes to keep out the sun, or go to a shopping mall, library or other building that is air-conditioned.
• Never leave an infant, elderly or disabled person or even a pet in a parked car with the windows closed.

To reduce over exposure to sunlight during prolonged periods outdoors, remember to:

• Apply at least SPF 15 sunscreen and lip balm, especially on children.
• Wear a hat.
• Wear sunglasses with an ANSI rating of 99 percent, and 98 percent UVA protection. These ratings should be found on the label of the sunglasses. Also, wear sunglasses that are either wraparounds or close fitting to prevent the sun from filtering from the side.
