Content: Additionally, wearing heavy or thick personal protective equipment and clothing can prevent workers from sweating properly, which prevents the body from effectively cooling. Workers can also adjust to working in high temperatures so their bodies can become better at cooling over time, though this adjustment requires a multi-week acclimatization process. Acclimatization
According to the National Institute for Occupational Safety and Health (NIOSH), acclimatization is a biological process that an individual will go through to adjust to a stimulus following continued exposure. Physiologically, acclimatization to heat will allow a worker’s body to more efficiently cool itself when exposed to high temperatures. When a worker has adjusted to working in a hotter environment, they will have a lower heart rate, earlier onset of sweating, and increased blood flow to blood vessels near the skin, allowing their body to more efficiently cool itself than a worker who is not acclimatized. See below section on acclimatization schedules for specific processes. Construction workers are at high risk for heat illnesses as their jobs are normally outside and require physical exertion. Examples of high risk occupations
Workers in many occupations are at high risk for exposure to heat stress. Especially vulnerable are outdoor workers who have highly physical tasks to complete, such as firefighters, miners, military personnel, construction workers, landscapers, athletes, delivery persons, and agricultural workers. Additionally, many indoor jobs also require high-exertion work in very hot conditions, for example factory workers, boiler room workers, welders, and kitchen staff.
