Sun Safety in the Summer

• Heat stroke is a life-threatening emergency that requires calling 911 immediately.
• Heat exhaustion, heat cramps, sunburn, and heat rash are all preventable with the right precautions.
• Champlain Medical provides occupational health and urgent care services for heat-related and workplace injuries year-round.

When summer temperatures climb in Vermont, sun safety moves to the top of the list for anyone spending time outdoors. The body regulates its core temperature through sweating, but when humidity exceeds 75 percent, that process becomes less effective — and when environmental temperatures surpass skin temperature, even a fan provides little relief. At Champlain Medical, we see the consequences of heat exposure firsthand through our occupational medicine and urgent care services, and we want our community to know how to stay safe when the heat is on.

Heat Stroke

The most serious condition on the heat-related illness spectrum is heat stroke, also called severe non-exertional hyperthermia. It carries a high mortality rate and can lead to respiratory failure, kidney failure, seizures, and swelling of the brain. Signs include a body temperature of 103°F or higher, hot and dry or flushed skin, a rapid strong pulse, confusion, and loss of consciousness. Heat stroke is a medical emergency — call 911 immediately, move the person to a cool location, apply cool cloths or a cool (not ice cold) bath, and do not give the person anything to drink. Our occupational health team regularly counsels employers and employees on recognizing this condition before it reaches a critical stage.

Heat exhaustion is less severe but still demands prompt attention. It presents with heavy sweating, cold and clammy skin, nausea, muscle cramps, dizziness, and fainting. Moving to a cool space, loosening clothing, applying cool wet cloths, and sipping water are the right first steps. However, if symptoms last more than an hour, worsen, or involve vomiting, seek medical help right away. Heat cramps — painful muscle spasms that occur during intense exercise — respond well to rest, hydration with water or a sports drink, and stopping physical activity until the cramps fully subside.

Stay Hydrated, Take Breaks

Prevention is always the best medicine when it comes to heat-related illness. Staying hydrated, taking breaks in the shade or indoors, wearing lightweight and light-colored clothing, and paying attention to heat index advisories all make a meaningful difference. For employers managing outdoor or physically demanding work environments, proactive workplace wellness programs and heat safety training are valuable tools for protecting your workforce all summer long.

Whether you're dealing with a heat-related illness or looking to set up a workplace safety program, Champlain Medical is here to help. Contact us today to schedule an appointment or learn more about our services.

Frequently Asked Questions

What is the difference between heat stroke and heat exhaustion?

Heat stroke is a life-threatening emergency characterized by a body temperature of 103°F or higher, confusion, and loss of consciousness — call 911 immediately. Heat exhaustion is less severe, presenting with heavy sweating, nausea, and dizziness, and typically improves with cooling and hydration.

How can I prevent heat-related illness at work?

Stay well-hydrated, take frequent breaks in cool or shaded areas, wear lightweight and light-colored clothing, and monitor the heat index. Employers can also implement formal heat safety programs through occupational health services.

When should I seek medical care for a sunburn?

Most sunburns can be treated at home with cool compresses, moisturizing lotion, and rest out of the sun. Seek medical attention if you develop large blisters, signs of infection, fever, or symptoms of heat exhaustion alongside the burn.
