Why is heat a serious concern on farms?
Farm work is outdoors, physical and often unavoidable. Heat can build over days, and tired, dehydrated people get hurt or sick. Animals and crops are affected too, and humidity makes heat harder to cope with.
The National Weather Service issues heat alerts, and the CDC and your county health department explain how to recognize and respond to heat illness. Check forecasts each day and adjust your work plan.
Build a simple routine that fits the heat, such as a long midday break, and tell everyone on the farm what it is so no one feels pressured to keep working.
How do you protect people?
Work in the cooler early hours and rest during peak heat. Drink water steadily, wear light, loose clothing and a hat, and take breaks in the shade. Plan heavier work when it is cooler, and do not work alone in extreme heat if you can avoid it. Regular meals help too, along with water.
Pay extra attention to older adults, young children, pregnant people and those with health conditions, who are at higher risk. Ask your doctor about medications that affect heat tolerance.
If someone is working in heat and starts to feel unwell, they should stop, move to shade and cool down. Do not ignore warning signs to finish a job.
- Start work at dawn
- Drink water before you feel thirsty
- Rest in shade
- Check on each other
What are the warning signs?
Heat illness can range from cramps and heavy sweating to dizziness, headache, nausea, confusion and fainting. Hot, dry skin, a very high body temperature or confusion can signal a medical emergency. Call emergency services right away and move the person somewhere cooler while you wait.
Do not wait for symptoms to pass on their own if someone seems seriously ill. Follow guidance from the CDC and emergency dispatcher.
Check on neighbors and relatives who live alone, especially older adults. A short phone call or visit during a heat wave can matter more than anything else you do.
How do you help animals cope with heat?
Provide shade, plentiful clean water and airflow. Avoid working, hauling or moving animals during peak heat. Watch for heavy panting, drooling, weakness, reluctance to move or loss of appetite, and call your veterinarian if you see them.
Some animals are more vulnerable, including those that are young, old, overweight or have dark or thick coats. Ask your veterinarian how to protect your species.
If an animal shows signs of heat stress, move it to shade and call your veterinarian for advice, rather than trying home remedies you read about.
- Shade and ventilation
- Clean, cool water in several spots
- Work animals only in cool hours
- Call the vet at early signs
What about crops and gardens?
Plants stress in heat too. Water deeply and early, mulch to hold moisture and consider shade cloth for sensitive crops. Harvest in the cooler morning and cool produce quickly.
Ask extension about which crops and varieties tolerate heat in your area.
Keep seedlings and young plants watered well, and consider moving potted plants to shade during the hottest part of the day.
How do you prepare homes and buildings?
Keep your house as cool as you can with shade, fans and closing curtains during the day. Barns and coops need airflow, since closed, hot buildings can be deadly for animals. Never leave people or animals in closed vehicles.
If you lose power, have a plan for cool places, such as a neighbor's house or a community building. Ask your county emergency office about cooling centers, if any exist in your area.
Provide extra water for pets and working dogs, and keep them out of hot trucks and trailers.
How do you plan for extreme heat events?
Make a plan before the heat arrives. Decide who checks on whom, how animals will get water if the power or pump fails, and how to change your work schedule. Write it down and share it with family and neighbors.
Ready.gov offers plain guidance on extreme heat preparedness.
Review your plan after each heat wave, and note what worked and what you would change.
