When the summer sun beats down, dairy farm work doesn’t slow, but the risk to workers grows. Heat exposure kills more people each year than floods, tornadoes, and hurricanes combined, making it a serious concern on farms.

According to the University of Wisconsin–Madison Division of Extension, protecting farm employees during extreme heat comes down to awareness, prevention, and quick action.

Recognizing Heat-Related Illnesses

The first step is knowing the warning signs.

• Heat exhaustion shows up as cool, clammy skin, heavy sweating, headaches, nausea, or dizziness. The best response is to move the person to shade, loosen clothing, cool them down with water, and offer fluids.

• Heat stroke is life-threatening. Symptoms include hot, dry skin, confusion, rapid pulse, and body temperatures that can spike above 105°F (40°C). In this case, call 911 immediately and begin cooling the person until help arrives.

Prevention Tips for the Barn and Field

Farm workers can beat the heat with a few practical steps:

• Dress smart: Wear light-colored, breathable clothing, along with hats, sunglasses, and sunscreen.

• Stay hydrated: Aim for a cup of water every 15–20 minutes. Avoid sugary, caffeinated, or alcoholic drinks.

• Take breaks: Do the heaviest tasks in the morning or evening. Rest often in shaded or ventilated areas—or air-conditioned rooms if possible.

The Bottom Line

Heat safety isn’t just about comfort, it’s about survival. By recognizing the signs of heat illness, drinking enough water, dressing for the conditions, and pacing the workday, dairy farms can keep their teams healthy and productive even in the hottest weather.
