Hypothermia
(Redirected from Low body temperature)
Hypothermia is a medical condition in which the body's core temperature drops below the normal range, usually as a result of prolonged exposure to cold temperatures, wind, or water. The human body needs to maintain a core temperature of approximately 98.6°F (37°C) for proper functioning. Hypothermia occurs when the body loses heat faster than it can produce it, leading to a dangerously low body temperature.
Causes of Hypothermia[edit | edit source]
Some common causes of hypothermia include:
- Prolonged exposure to cold weather without adequate clothing or protection
- Submersion in cold water, such as in the case of a boating accident or falling through ice
- Wearing wet clothing in cold or windy conditions
- Inadequate heating in the home, especially for the elderly or infants
Individuals with a higher risk of hypothermia include the elderly, infants, people with certain medical conditions (such as diabetes, hypothyroidism, or cardiovascular disease), and those under the influence of alcohol or drugs.
Symptoms[edit | edit source]
Hypothermia can be classified into three stages based on the severity of the condition: mild, moderate, and severe.
Mild hypothermia[edit | edit source]
- Shivering
- Cold and pale skin
- Fast breathing
- Feeling tired or lethargic
- Impaired coordination
- Mild confusion
Moderate hypothermia[edit | edit source]
- Intense shivering or shivering stops
- Slurred speech
- Confusion and disorientation
- Loss of coordination and muscle stiffness
- Slow, shallow breathing
- Weak pulse
Severe hypothermia[edit | edit source]
- Unconsciousness
- Absence of shivering
- Shallow or absent breathing
- Weak, irregular, or absent pulse
- Dilated pupils
- Stiff, cold skin
Treatment[edit | edit source]
If you suspect someone is suffering from hypothermia, it is crucial to take immediate action:
- Call for emergency medical help.
- Move the person to a warmer environment if possible.
- Remove any wet clothing and replace it with warm, dry clothing or blankets.
- Warm the person's core first by covering the chest, neck, head, and groin area with blankets or using your own body heat.
- If the person is conscious and able to swallow, offer warm, non-alcoholic beverages to help raise their body temperature.
- Do not use direct heat sources, such as heating pads or hot water, as they may cause burns or rapid temperature fluctuations.
In a medical setting, healthcare professionals may use additional techniques to warm the patient, such as warmed intravenous fluids, heated blankets, or even warm, humidified oxygen.
Prevention[edit | edit source]
To prevent hypothermia, take the following precautions when exposed to cold temperatures:
- Dress in layers to trap body heat, and wear a hat, gloves, and warm, waterproof footwear.
- Keep clothing dry and change wet clothes as soon as possible.
- Avoid consuming alcohol, as it can impair the body's ability to regulate temperature.
- Stay active to maintain body heat, but avoid excessive sweating.
- Take frequent breaks in warm, sheltered areas during cold weather activities.
