WAITE PARK, Minn. — Winters in Minnesota are infamous for their unpredictable swings between “rather chilly” and “bitter cold.” For livestock managers, the work doesn’t stop when temperatures plunge. Chores must go on, whether it’s a mild 61°F or a frigid 16°F. Those who live in cold climates often have vivid memories of the bone-chilling days that left them miserable. While many farmers have established effective cold-weather habits, there’s always room to improve safety and comfort. This article aims to provide practical tips on preparing for and managing the challenges of working outdoors during the colder months.
Understanding Hypothermia and Frostbite
When most people think of hypothermia, they imagine a stranded movie character, shivering in the snow with blue lips.
However, hypothermia can set in during everyday activities when the body loses heat faster than it can generate. Symptoms start subtly with shivering, fatigue, and a loss of coordination. If ignored, they progress to more severe signs like dilated pupils, blue lips, and slowed pulse and breathing.
Frostbite is another cold-weather hazard, often affecting extremities such as fingers, toes, and noses. Early indicators include tingling, numbness, and pale or bluish skin, as reduced blood flow leaves these areas vulnerable.
A less commonly discussed condition is Immersion Hypothermia, which can occur in milder temperatures, around 40°F, especially when people are exposed to rain, sweat, or cold water. Symptoms mirror those of hypothermia and can develop quickly. Recognizing these dangers is vital, as pushing through discomfort or ignoring body signals can have long-term consequences.
Dressing for Success: Layering on the Warmth
The cornerstone of safe and comfortable winter work is wearing the right clothing, and layering is the key. Each layer serves a specific purpose:
- Base Layer: This inner layer should be loose and made of moisture-wicking materials like wool or synthetic fabrics. These materials help keep your core dry by pulling sweat away from the skin. The loose characteristic of base layers allows for better air circulation and for individuals to heat the air next to their body, simply adding another layer of warmth.
- Outer Layer: The final barrier should be wind and water-resistant to protect against harsh weather conditions.
Covering exposed areas is equally crucial. Be sure to keep your nose, ears, cheeks, chin, neck, fingers, and toes warm and dry. Wet gloves or boots can lead to frostbite, and always start with dry gear. Avoid tight footwear, as it restricts blood flow, increasing the risk of frostbite. Store boots in a warm, ventilated area overnight to ensure they’re ready for the next day. Questions or comments can be directed to Dana Adams at [email protected] or (320) 204-2968.
