What should be done to mitigate heat stress in the workplace?

Using cooling devices is an effective strategy for mitigating heat stress in the workplace. These devices, such as fans, air conditioning, or specialized cooling vests, help lower the ambient temperature or enhance heat dissipation from the body. By promoting airflow and reducing humidity levels in the work environment, cooling devices can help maintain a comfortable state for employees and prevent the adverse effects associated with excessive heat exposure, such as heat exhaustion or heat stroke.

In contrast, limiting fluid intake would actually increase the risk of heat stress, as hydration is vital for thermoregulation and maintaining bodily functions in hot conditions. Increasing humidity can trap heat and make it harder for the body to cool down, exacerbating the effects of heat stress. Similarly, avoiding ventilation can lead to a stagnant environment that traps heat, further increasing stress on the body. Therefore, utilizing cooling devices is the most effective option to ensure a safe and comfortable working environment in hot conditions.
