Even in cold weather …
employees can get overheated …
Most people might not think about heat risks during colder months, but they lurk in workplaces where high temperatures and poor ventilation are typical.
These enclosed spaces can trap hot air, creating a perfect storm for illnesses. Dehydration sneaks up faster in winter since the thirst response is 40% lower when it’s cold. Medications that affect the body’s ability to cool itself can also make it more difficult to cool down.
Winter clothes are designed to keep the wearer warm outside but can cause overheating indoors. Heating systems working overtime can amplify discomfort.
Cold outdoor temperatures can mask the symptoms of overheating, as the body reacts differently in cooler weather. Workers may not feel sweaty, as the cold air quickly evaporates moisture from the skin, making it seem like they’re not losing fluids.
Similarly, the cold suppresses the thirst response, so they’re less likely to drink water.
Winter doesn’t eliminate heat risks; it just makes them easier to overlook.
