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. Again, cool down and drink some juice. Be sure that your diet during the summer includes foods to replace the salt lost. Sometimes, due to extreme heat, a person will faint especially when standing still in the sun.
