Weather Service: Heat Index Could Hit 105° Tuesday

With a high of 92° and a heat index of up to 105° forecast for the area Tuesday, the National Weather Service has issued a heat advisory for the afternoon and evening hours.

The alert, in effect from noon to 9 p.m., means that the combination of heat and humidity "is expected to make it feel like it is 100° to 104° for two consecutive hours."

"Take extra precautions if you work or spend time outside," the service advises. "When possible, reschedule strenous activities to early morning or evening."

Anthony Ardolino, M.D., senior associate dean of academic and student affairs at the Quinnipiac University School of Medicine, offers these tips for keeping cool:

• Common sense: Limit exposure to sun and use sunscreen; wear loose clothing, hats or sun umbrellas, and light fabrics; and avoid strenuous outside activities during daylight.

• Most important: Drink water frequently, including before entering the heat. The single most important way to prevent heat stroke is to be well hydrated (to allow sweating/evaporation, which cools). In contrast, limit intake of caffeinated and alcoholic beverages, which are both diuretics and may lead to dehydration.

• Less intuitive: Wear light colors, which reflect sunlight (black absorbs). If exercise/strenuous work is required, do it early or late in the day. Patients on certain medications are at greater risk (diuretics for hypertension, etc. — patients should check with their healthcare provider). If physical activity is required, do not use antiperspirants (again, sweating cools).
