Symptoms
- Limit the amount of time spent outdoors in the cold
- Wear synthetic and wool fabrics, which keep you warmer than cotton
- Dress in layers with a protective wind-breaking shell for the outermost layer
- Wear a warm, lined hat and gloves
- Wear synthetic, moisture-wicking socks
- Wear shoes that are not too tight
Causes
To effectively treat frostbite, Polin recommends:
- Get the child out of the cold and out of wet clothing.
- Gentle warming with warm water (not hot) that's a tad higher than body temperature.
- This will improve circulation and stop progression of frostbite.
- This may hurt initially but will get better as the body starts warming.
Prevention
patients with a high anxiety level were found to have a 2.17-fold higher risk of hypothermia during the first hour and a 1.77-fold higher risk of hypothermia during the first 2 hours than patients with a low/moderate anxiety level.
Complications
Therapeutic hypothermia buys the patient more time … and “makes a huge difference in outcomes.” During the life-saving process, a patient’s body temperature is cooled to 93 degrees Fahrenheit and kept at that temperature for 24 hours, an approach that both decreases inflammation and reduces brain swelling.

What is the cause of hypothermia?
Hypothermia is caused by prolonged exposures to very cold temperatures. When exposed to cold temperatures, your body begins to lose heat faster than it's produced. Lengthy exposures will eventually use up your body's stored energy, which leads to lower body temperature.

Frostbite is a type of injury caused by freezing. It leads to a loss of feeling and color in the areas it affects, usually extremities such as the nose, ears, cheeks, chin, fingers, and toes. Frostbite can permanently damage the body, and severe cases can lead to amputation (removing the affected body part).
Why is hypothermia dangerous?
This makes hypothermia especially dangerous, because a person may not know that it’s happening and won’t be able to do anything about it.

Treatment depends on the degree of hypothermia, but the aim will be to make the person warm.
Why does hypothermia occur?
Medical causes. Other causes of hypothermia include metabolic disorders that result in a lower basal metabolic rate. These disorders cause the body to generate less heat internally. Exposure to toxins and dysfunction of the thyroid, adrenal, or pituitary glands may also be underlying causes.
What happens when the body temperature falls below a safe level?
Hypothermia happens when the body temperature falls below a safe level, and it can be fatal. Infants and older people are especially at risk.

Share on Pinterest. Hypothermia happens when the body cannot produce enough energy to keep warm. Older people and children are especially susceptible. Hypothermia is a severe condition in which the body temperature drops to an abnormally low level. It occurs when the body is unable to produce enough heat to counter the heat that it is losing.
Why does hypothermia happen indoors?
Indoor causes. Indoors, a lack of heating, excessive air conditioning or taking an ice bath can result in hypothermia. Indoor hypothermia often has a poor outcome, because it tends to affect older people, and the diagnosis often comes at a late stage.
