Hipotermia adalah suatu kondisi di mana mekanisme tubuh untuk pengaturan suhu kesulitan mengatasi tekanan suhu dingin. Hipotermia juga dapat didefinisikan sebagai suhu bagian dalam tubuh di bawah 35 °C. Tubuh manusia mampu mengatur suhu pada zona termonetral, yaitu antara 36,5-37,5 °C.
Hypothermia is defined as a body core temperature below 35.0 °C (95.0 °F) in humans. Symptoms depend on the temperature. In mild hypothermia, there is shivering and mental confusion. In moderate hypothermia, shivering stops and confusion increases.
- Mainly exposure to extreme cold
- >37.5 or 38.3 °C (99.5 or 100.9 °F)
- 1,500 per year (US)
- Based on symptoms or body temperature below 35.0 °C (95.0 °F)
Hipotermia (daripada bahasa Yunani kuno: ὑπο, ypo, "bawah", dan θερμία, thermía, "haba") merujuk kepada pengurangan suhu badan yang berlaku apabila badan manusia melepaskan haba pada kadar yang lebih banyak daripada haba yang diserap. Manusia mengalaminya apabila suhu teras badan berada di bawah 35.0 °C (95.0 °F).

Hypothermia is a condition when a person is so cold that the body temperature drops below normal. Hypothermia is any body temperature lower than 35.0 °C. Someone with hypothermia starts shivering and cannot stop. The person then becomes confused and acts strange. Their words don't make sense and they may be clumsy. Sometimes they become very tired. If someone gets hypothermia, wrap the person in blankets and take them to the hospital. If that's impossible, warm up the person slowly and give ...

Definition: Core Temperature <35°C
1. Unintentional hypothermia (core cooling <35°C) is associated with significant morbidity and mortality. Roughly 1500 persons die of accidental hypothermia in the US annually. 2. Despite the high mortality associated with pre-hospital arrest, well-directed treatment can result in complete neurologic recovery in the hypothermic patient. 3. 50% who die of hypothermia are >65 years old 4. Risk of cardiac arrest increased with temperature <32°C, as stable cardiac rhythms can quickly degenerate i...

- Risk Factors
Hypothermia is a medical emergency that occurs when your body loses heat faster than it can produce heat, causing a dangerously low body temperature. Normal body temperature is around 98.6 F (37 C). Hypothermia (hi-poe-THUR-me-uh) occurs as your body temperature falls below 95 F (35 C). When your body temperature drops, your heart, nervous system and other organs can't work normally. Left untreated, hypothermia can lead to complete failure of your heart and respiratory system and eventually to death. Hypothermia is often caused by exposure to cold weather or immersion in cold water. Primary treatments for hypothermia are methods to warm the body back to a normal temperature.
Shivering is likely the first thing you'll notice as the temperature starts to drop because it's your body's automatic defense against cold temperature — an attempt to warm itself. Signs and symptoms of hypothermia include: 1. Shivering 2. Slurred speech or mumbling 3. Slow, shallow breathing 4. Weak pulse 5. Clumsiness or lack of coordination 6. Drowsiness or very low energy 7. Confusion or memory loss 8. Loss of consciousness 9. Bright red, cold skin (in infants) Someone with hypothermia usually isn't aware of his or her condition because the symptoms often begin gradually. Also, the confused thinking associated with hypothermia prevents self-awareness. The confused thinking can also lead to risk-taking behavior.
Hypothermia occurs when your body loses heat faster than it produces it. The most common causes of hypothermia are exposure to cold-weather conditions or cold water. But prolonged exposure to any environment colder than your body can lead to hypothermia if you aren't dressed appropriately or can't control the conditions. Specific conditions leading to hypothermia include: 1. Wearing clothes that aren't warm enough for weather conditions 2. Staying out in the cold too long 3. Being unable to get out of wet clothes or move to a warm, dry location 4. Falling into the water, as in a boating accident 5. Living in a house that's too cold, either from poor heating or too much air conditioning
Risk factors for hypothermia include: 1. Exhaustion.Your tolerance for cold diminishes when you are fatigued. 2. Older age.The body's ability to regulate temperature and to sense cold may lessen with age. And some older adults may not be able to communicate when they are cold or to move to a warm location if they do feel cold. 3. Very young age.Children lose heat faster than adults do. Children may also ignore the cold because they're having too much fun to think about it. And they may not have the judgment to dress properly in cold weather or to get out of the cold when they should. 4. Mental problems.People with a mental illness, dementia or other conditions that interfere with judgment may not dress appropriately for the weather or understand the risk of cold weather. People with dementia may wander from home or get lost easily, making them more likely to be stranded outside in cold or wet weather. 5. Alcohol and drug use. Alcohol may make your body feel warm inside, but it cause...
People who develop hypothermia because of exposure to cold weather or cold water are also vulnerable to other cold-related injuries, including: 1. Freezing of body tissues (frostbite) 2. Decay and death of tissue resulting from an interruption in blood flow (gangrene)
Staying warm in cold weather
Before you or your children step out into cold air, remember the advice that follows with the simple acronym COLD — cover, overexertion, layers, dry: 1. Cover.Wear a hat or other protective covering to prevent body heat from escaping from your head, face and neck. Cover your hands with mittens instead of gloves. 2. Overexertion.Avoid activities that would cause you to sweat a lot. The combination of wet clothing and cold weather can cause you to lose body heat more quickly. 3. Layers.Wear loo...
Keeping children safe from the cold
To help prevent hypothermia when children are outside in the winter: 1. Dress infants and young children in one more layer than an adult would wear in the same conditions. 2. Bring children indoors if they start shivering — that's the first sign that hypothermia is starting. 3. Have children come inside frequently to warm themselves when they're playing outside. 4. Don't let babies sleep in a cold room.
Winter car safety
Whenever you're traveling during bad weather, be sure someone knows where you're headed and at what time you're expected to arrive. That way, if you get into trouble on your way, emergency responders will know where to look for your car. It's also a good idea to keep emergency supplies in your car in case you get stranded. Supplies may include several blankets, matches, candles, a clean can where you can melt snow into drinking water, a first-aid kit, dry or canned food, a can opener, tow rop...
