Many people, particularly those who do demanding labor in hot and humid working conditions, suffer from heat stress, particularly in the summer. Workers' health and productivity are both adversely affected by excessive heat.Rashes, cramps, tiredness, and, in the worst-case scenario, heatstroke are all symptoms of heat stress. While heat rashes and heat cramps are unpleasant, heat exhaustion is far more dangerous and requires urgent medical attention.
Heat-related sickness has plenty of warning indicators. By observing these warning signs, workers can better regain control of the situation. Dizziness, lightheadedness, headache, nausea, vomiting, and diarrhea are some of the warning symptoms. Redirecting blood from internal organs and muscles to the skin results in these symptoms. Dehydration results from sweating.
How does heat stress start?
As the air and skin temperatures normalize, radiation stops working. Convection is no longer possible since the circulating air is now warm rather than cool. Conduction is not possible if there is nothing cool to contact. In addition, if the air is humid, sweat will not evaporate.Heat stress is likely at temperatures between 85 and 95 degrees Fahrenheit, with humidity levels ranging from 30 to 60%. Workers are in even more danger when the temperature goes beyond 95 degrees F and the humidity rises above 60%. Due to exposure to high temperatures workers develop heat rash, heat cramps heat exhaustion, or heat stroke which can cost workers life.
Employees should take additional efforts to prevent heat-related illnesses, especially while working in warm weather or outside. When people cannot control their internal body temperature, they become ill from it. Sweating is a natural method to cool down in hot weather. Sometimes, sweating alone isn't enough. A very sweaty workout, excessive heat, and little to no ventilation are examples of such scenarios. Medical conditions and medications may also reduce a person's tolerance to heat.

Prevention from Heat Stress
Heat stress can be lessened with several measures. Knowing the signs and symptoms of heat stress provides the opportunity to take action. Also, in outdoor workplaces, it is better to work in teams rather than individually. This will ensure that if a worker suffers from heat stress, there will be someone available to help. Having a regular outdoor exercise routine can also be very beneficial for combatting heat stress. Such activities allow our bodies to acclimatize to warm weather allows them to better cope with excessive heat conditions.
Drinking plenty of cool water throughout the day can help to mitigate the effects of heat and humidity. At outdoor workplaces, workers should be allowed to take periodic breaks and shade should be provided. Wearing appropriate clothing also helps in coping with the heat. Loose and light-colored clothing help one keep cool. Loose clothing allows air circulation to the body, while light colors do not absorb a lot of heat and help keep body temperatures cool.
What we consume also has an impact on our body temperatures. Caffeinated and alcoholic beverages should be avoided before or during work hours, as they cause dehydration. Drinking water is the best way to keep ourselves hydrated. So, a healthy daily water intake will help cope with heat stress.
Summary
Take your time adjusting to the heat and humidity. A heatwave strains your body. Reduce your exercise until you get used to the heat, and you will have more stamina. Adjusting to difficult conditions may take days or weeks. Gradual adaptation increases workers' capacity to sweat, which cools the body and helps maintain a stable temperature.
Headache, dizziness, lightheadedness, fainting, weakness, malaise, mood change, mental disorientation, and nausea or vomiting are all symptoms of heat-related sickness. If you display any of these symptoms, go to the hospital immediately.
