Heat Related Issues, Heat Exhaustion and Heat Exposure.
Heat exposure is a common concern for many professionals who work primarily outdoors. It is a natural danger; one many of us face every day. Many studies have been conducted on how high temperatures affect the human body and how individual peoples react differently.
Normal, healthy adults have many ways in which they can handle high temperatures – perspiration or sweating which allows for evaporative cooling. People also experience the dilation of blood vessels (which increases blood pressure). This adaptation allows for the body to keep the blood from being near the skin where it warms up, and it can speed up heat loss by convection.
We know there is a connection between high temperatures and heat-related illness and death. The CDC recognizes that workers over 65 years of age, those who are overweight, and those who have heart disease or high blood pressure, or take medications are more likely to be affected by extreme heat.
What symptoms and signs should you be looking out for when temperatures rise?
If you begin to feel any of these symptoms, immediately rest in a cool or air-conditioned space. If possible, take a cool shower. If extreme symptoms exist, find medical assistance immediately.
What can you do help prevent heat stress or heat exhaustion?
Working in hot, humid conditions is part of working as a PMP. Good general health habits such as not smoking, moderate alcohol use, and a healthy diet can help your body be prepared for additional stresses such as heat during the long summer months.
