Hypothermia

Hypothermia

Hypothermia is a medical emergency. Your body loses heat much faster than it produces heat and causes dangerous low body temperatures. Your normal body temperature is 98.6 degrees Fahrenheit (37 degrees Celsius) and when your body temperature falls to 95 degrees Fahrenheit (35 degrees Celsius) your nervous system, heart and internal organs don”t work properly. If left untreated, hypothermia will lead to failure of your organs, respiratory system and you may die.

Symptoms and Causes

Hypothermia begins gradually and you may experience confused thoughts. This situation prevents self-awareness of what may be happening within your body. If you are able, be aware of what is happening to your body.

Symptoms

  • Shivering
  • Unclear speech
  • Uncoordinated walking
  • Inability to make decisions
  • Removing warm clothing
  • Low energy or drowsiness
  • Indifference
  • Slow loss of consciousness
  • Weak or very slow pulse
  • Shallow or very slow breathing

You do not necessary have to be exposed to extremely cold outdoor temperatures to have hypothermia. The elderly may develop mild hypothermia indoors if the heat is turned down or the air conditioning too high. Mild hypothermia symptoms are almost identical to more severe symptoms. If you are the caretaker of an older person, do watch for these same symptoms.

Hypothermia can also occur in infants indoors or outdoors. Watch for bright red and cold skin and very low energy or an infant that acts lethargic.

Prolonged exposure to environmental conditions colder than your body can cause hypothermia and additional causes are:

Wearing clothes not adequate for weather conditions

Staying out in the cold or long periods of time

Unable to get out of wet clothes and move to a dry location

Accidental falls in cold water

Wind causes hypothermia by blowing away body heat from the thin layer of warm air at your skin”s surface. Watch out for wind chill factors; they are direct factors of hypothermia. You will lose body heat very quickly when you are in contact with cold and wearing wet clothing.

Hypothermia is a cause of:

There are definite factors putting you at risk for hypothermia. Those who are 65 and older are very vulnerable to hypothermia due to the body”s temperature regulators becoming inefficient. Older people may have medical conditions affecting temperature regulations. Older adults may not be mobile enough to move to somewhere warmer or they may not be able to express their cold complaints.

Children tend to lose heat much faster than adults. Children really don”t think about how cold they are and just keep moving through icy conditions. Generally children do not have the judgment to dress properly for cold weather nor do they really care. Infants have less resourceful apparatuses for generating heat. They do get cold quickly. Forget the myth if you are warm so is your baby; this is just not true.

Those with mental problems or dementia may not dress appropriately for the weather or understand the risk of being in the cold. Dementia patients tend to wander away from warm homes and become stranded outside in cold or wet weather.

Alcohol makes your body feel warm inside but causes blood vessels to dilate or expand. This causes rapid heat loss from your skins” ™ surface. Your judgment may be impaired if you use alcohol regularly or are a habitual recreational drug user. An intoxicated or drugged person may pass out the cold and lie there for ages. Hypothermia sets in.

Medical conditions that contribute to hypothermia risks include underactive thyroid, poor nutrition, severe arthritis, Parkinson”
