Farmers Urged to Prevent Heat Stress Risks

By Andi Anderson

Summer heat creates serious safety risks for agricultural workers who perform physically demanding outdoor tasks. High temperatures combined with heavy work can cause the body to overheat and may lead to dangerous heat-related illnesses. Farmers and employers are encouraged to take preventive steps to protect workers during hot weather.

Michigan State University highlighted how a Michigan farm worker’s heat stroke case shows the importance of preparation and quick action. The worker spent several hours outdoors during a period when temperatures were above 90°F. After feeling overheated, the worker was moved to shade and given water but later became unresponsive. Despite medical efforts, the worker died from heat stroke, showing how quickly heat stress can become life-threatening.

Several factors increase the risk of heat-related illness. Weather conditions such as high temperature, humidity, and direct sunlight can make it harder for the body to cool itself. New or returning workers also face higher risks because the body needs time to adjust to hot conditions. Proper acclimation can take several days and helps workers safely handle outdoor tasks.

Heavy workloads, protective clothing, dehydration, certain health conditions, medications, and previous heat illness can also increase risk. Workers should recognize warning signs such as tiredness, thirst, dizziness, muscle cramps, confusion, nausea, or fainting.

Severe symptoms, including loss of consciousness, seizures, rapid pulse, high body temperature, or hot dry skin, require immediate medical help. Call 911, move the person to a cooler area, and begin active cooling with ice, cold towels, fans, or other methods while waiting for assistance.

Preventing heat stress requires planning. Workers should drink enough water, take regular breaks in shaded areas, wear suitable clothing, and allow time for their bodies to adjust to changing weather conditions. Employers should create heat safety plans, provide training, offer cool drinking water, and establish work and rest schedules.

Monitoring temperature and humidity throughout the day can help identify dangerous conditions. Tools such as heat safety apps can support planning and emergency preparation.
