Working in hot conditions, such as bakeries and kitchens, can lead to heat stress, especially if there is a low level of air movement or poor ventilation.
When working in a hot environment, the body needs to disperse heat more effectively. A person not used to working in hot conditions can react differently to someone who is. This can lead to heat-related illnesses such as headaches, weakness, nausea and vomiting.
