Transcript of Hypothermia

Hypothermia Hypothermia is when your body doesn't produce heat fast enough to keep the body at its normal temperature due to cold or cool temperatures outside the body. There are three main ways to lose body heat, they include; Radiated heat, Direct contact, and Wind. The first way, radiated heat, is how the most heat is lost out of your body. It is when heat is released from all of the exposed skin of your body. Your head has a large surface area and accounts for about half of all heat loss when it is uncovered by a hat or something else. The second is direct contact which is when you're in direct contact with something very cold, such as cold water or the ground. Heat is taken away from your body while it is in contact with the cold substance. Because water is very good at transferring heat from your body, body heat is lost much faster in cold water than in cold air. Als0, heat loss from your body is much faster if your clothes are wet, like when you're caught outside during a rainy day. Wind removes body heat by carrying away the thin layer of warm air at the surface of your skin. The wind chill factor is important when dressing for certain inviroments because when the wind chill is high it causes alot of heat loss.
Symptoms Symptoms include,
Shivering
Clumsiness or lack of coordination
Slurred speech or mumbling
Stumbling
Confusion or difficulty thinking
Poor decision making, such as trying to remove warm clothes
Drowsiness or very low energy
Apathy, or lack of concern about one's condition
Progressive loss of consciousness
Weak pulse
Shallow breathing Some people can get hypothermia indoors from poorly heated homes or even an air conditioned room.

Symptoms indoors include,
Confusion
Lack of coordination
Dizziness
Nausea or vomiting
Fatigue Signs and symptoms for infants include,
Bright red, cold skin
Very low energy
Also the other symptoms as listed before.
Older age: People 65 years old or older are at a higher risk of getting hypothermia because the body's ability to regulate body heat decreases as you get older. Very young age: Children have a higher head to body ratio then adults do, therefore they lose body heat faster. Children could also get hypothermia by ignoring the cold they are feeling because they are having to much fun playing. Alcohol and drug use: The use of alcohol will make your body feel warmer then it is because your blood vessels expand resulting in more rapid heat loss. Medications: Some antiseptic drugs and sedatives may restrict your judgment on what type of clothes you should wear according to the weather conditions. Risk Factors Certain medical conditions: Some medical conditions may restrict the ability of the body to produce heat. Mental impairment:People with a mental illness, dementia or any other mental impairments that impair judgment may not dress appropriately for the weather or realize the risk of cold weather. The third is wind. There are a few other risk factors, but those were the main ones that harm people each year. The end
