1. Choose clothing based on the job, not just the temperature.
2. Dress in an area similar to the work environment.
3. Wear breathable thermal underwear.
4. Regularly ventilate your clothing and shoes.
5. Avoid wearing clothes that are too small or tight. Poor blood circulation reduces the body's ability to generate heat.
6. Drink plenty of water and reduce your consumption of caffeinated and hot beverages. Your body needs a lot of water to effectively combat the cold. Caffeine acts as a diuretic, so you risk dehydration. Hot drinks may make you sweat.
7. Do not smoke and avoid alcohol. Nicotine and alcohol greatly influence the body's ability to regulate and retain heat, especially for extremities.
8. Eat more! At least 3000 to 4000 calories per day are recommended in extremely cold environments.
9. Do not expose your skin. Exposed skin can freeze quickly. At temperatures of 0°C and below, the skin can freeze in less than 15 seconds. Avoid touching cold metal or plastic objects with bare skin.
10. Do not ignore your body's signals. Cold hands and feet indicate that your body temperature has dropped. If your hands and feet are cold, make sure your head is well covered. If you feel numb, experience loss of coordination, shivering, or slow breathing, get warm.
