As we have entered the fall season I thought it would be a good time to discuss some pre-cautions to take with the upcoming cooler weather.

Many times during the workday we are required to spend working in cooler environments. Usually the body can naturally produce enough heat to keep warm and function normally. However, sometimes extremely cold temperatures can cause the body to lose heat faster than it can be produced. The body reacts by directing blood to the vital organs, leaving hands and feet feeling cold. If the body temperature continues to drop, shivering starts to help generate heat. A further drop in body temperature can cause tissue or organ damage, and even death.

Common Effects Caused by Cold Temperatures:

1. Feet and legs become cold, pale, and numb, and sweating stops; then feet turn red and swell. Blood vessel and nerve injuries are frequent. Get into a warm temperature and change out wet clothing to avoid injury.
2. Frostbite occurs after exposure to very cold temperatures. The skin becomes pale and glossy, blisters may appear, gangrene may set in, and when warmed, swelling may occur. These injuries may range from minor to severe and in some instances results in amputation or death. If these symptoms are observed, seek medical attention. Do not rub the effected areas in an attempt to warm.
3. Hypothermia is the body’s inability to keep its core temperature above 98 degrees F. Hands and feet become cold, and finally numb. Severe shivering begins, and it is this shivering that marks the real first sign of hypothermia. Other signs are difficulty with speech, forgetfulness, and drowsiness. If these symptoms are observed, the body the body must be warmed immediately, death could follow quickly.

Preventive Measures for Dealing with Cold Temperatures:

1. Know the symptoms of cold-related disorders.
2. Drink hot liquids, avoid alcohol and smoking.
3. Wear layered clothing starting with thermal underwear, an insulating layer next, outer garments that repel wind and water, head and ear coverings, warm and waterproof boots, and warm gloves.
4. Add or remove layers according to changes in the weather and/or workload; make sure clothing is not tight enough to cut off circulation, and keep dry.

As you can see it is important to take precautions when working in cooler weather. Remember you can always take layers of clothing off when needed.
