The Heat Is On

Acclimatization – the process of becoming accustomed to a change in climate – is one way our bodies protect us from heat and cold. Delivery drivers are out in the elements every day. They naturally experience acclimatization, but even they are at risk of sharp increases and decreases in temperatures. Make sure your drivers know the signs of heat stress and be sure you take precautions to keep them safe.

Identifying key heat-related symptoms

Heat rash: Also known as prickly heat, heat rash is skin irritation caused by sweat that does not evaporate from the skin. Heat rash is the most common problem in hot work environments.

Heat cramps: Heat cramps are caused by the loss of body salts and fluid during sweating. The low salt levels in muscles cause painful cramps. Tired muscles that are used for performing work are oftentimes the ones most affected by cramps. Cramps may occur during or after working hours.

Heat exhaustion: Heat exhaustion is the body’s response to loss of water and salt from heavy sweating. Signs include headache, nausea, dizziness, weakness, irritability, thirst and heavy sweating.

Heat stroke: This is the most serious form of heat-related illness and happens when the body cannot regulate its core temperature. Sweating stops and the body can no longer rid itself of excess heat. Signs include confusion, loss of consciousness and seizures. If you are experiencing heat stroke symptoms, call 911 immediately, as this is a medical emergency that may result in death.

Heat Precautions

Drinking Water

Providing cool drinking water is a simple thing that can go a long way in safeguarding employees. The human body naturally sweats to cool itself. However, this can result in a significant loss of fluid that must be replenished during the workday.

While iced coffee may be delicious, it’s not a good choice for a cooling beverage. Caffeine can cause dehydration; drivers should limit caffeine consumption whenever possible.

Cooling Clothing

Moisture wicking fabrics are an excellent choice for summer wear. If your drivers wear a uniform, check with the supplier to see if options are available using these high-tech fabrics.

Cooling vests and neck wraps work by chilling the body’s core. There are great options for those who may be sensitive to the heat or if you’re located in an especially hot part of the country.
