4. Exercising in hot weather When you exercise, blood flow is concentrated in the working muscles, causing a heat buildup. Hyperthermia: a reduction of body fluids or an increase in in body temperature. Heat Cramps: certain muscles will contract involuntarily and will cause pain. Heat Exhaustion: a condition characterized by profuse sweating accompanied by diziness and extreme weakness.

5. Exercising in hot weather cont... Heat stroke: characterized by hot, dry skin and a rising body temperature which may reach 106 degrees.

6. Preventive measures for heat illness 1. Light-weight and perforated clothing with adequate exposure of arms and legs promote the escape of heat from the skin surfaces. Lighter colors are preferred since they reflect rather than absorb the sun’s rays. 2. Rubberized suits do not promote permanent weight reduction, as many people believe. Such suits can be very dangerous because they can cause an elevation of the internal body temperature.

7. Preventive measures for heat illness cont... 3. Drink fluids before, during, and following your exercise sessions. Hydrating is important even if you are not thirsty. 4.
