    Fever occurs when an area in your brain called the hypothalamus (hi-poe-THAL-uh-muhs) — also known as your body's \\"thermostat\\" — shifts the set point of your normal body temperature upward. When this happens, you may feel chilled and add layers of clothing or wrap up in a blanket, or you may shiver to generate more body heat, eventually resulting in an elevated body temperature.Normal body temperature varies throughout the day — it's lower in the morning and higher in the late afternoon and e...

    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 eventually lead to complete failure of your heart and respiratory system and ev...

    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 usua...

    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 ge...

    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...

    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)

    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...
