It's easier to talk cool than to stay cool some summer days, but heat illness can make you sick, put you in the hospital, and even kill you. Your reaction to the heat may take the form of a heat rash. It isn't life threatening, but it isn't pleasant either, and it is a sign that the weather is affecting you. Lotions that block pores contribute to prickly heat, as do synthetic fabrics. A shower after each workshift should help, along with a sprinkling of talcum powder or cornstarch.
Heat stress is another common reaction to high temperatures.
Thirst, tiredness, dizziness, even trouble seeing are indications of heat stress. If the heat seems to be getting to you with one or more of these symptoms, take a break and drink some water or fruit juice to replace lost body fluids. Heat cramps are another sign of heat sickness. They are painful muscle spasms in the arms, legs, or intestines. Losing salt while sweating causes heat cramps.
