Prevention and response to low temperatures
Extreme cold requires proper preparation to conserve body temperature and recognize the changes caused by exposure.
Hypothermia occurs when the body loses heat at a faster rate than it can produce it; low temperatures, wind, humidity, and inadequate clothing can accelerate this process, especially during prolonged exposure.
How to protect yourself from extreme cold and prevent hypothermia?
Protection begins with clothing adapted to weather conditions; wearing several layers of clothing helps better conserve body heat and allows you to adjust your attire based on activity.
The head, hands, and feet require specific protection through the use of a hat, gloves, and appropriate footwear.
Outerwear should protect against wind and humidity. Wet clothing promotes rapid heat loss, so it is advisable to change into dry clothes. During outdoor activities, it is also useful to take breaks in sheltered places and maintain proper nutrition and hydration.
Prevention includes monitoring exposure time and checking weather forecasts before engaging in outdoor activities.
At home, an adequate indoor temperature, a well-functioning heating system, and sufficient insulation help conserve heat.
Elderly people, infants, and those with certain medical conditions may require special monitoring during prolonged episodes of low temperatures.
Checking their condition periodically allows for the detection of changes related to cold exposure.
How to recognize the symptoms of hypothermia?
Early signs help identify potential hypothermia in its initial stages.
Symptoms that require attention include shivering, an intense feeling of cold, cold skin, fatigue, clumsiness, and difficulty performing precise movements. Coordination issues and difficulty maintaining focus may also occur.
When body temperature continues to drop, more serious signs appear: confusion, drowsiness, slow or slurred speech, significant loss of coordination, and increasingly slow responses.
In advanced hypothermia, slow breathing, a slow pulse, altered consciousness, and a decrease or cessation of shivering may occur. The absence of shivering during prolonged cold exposure requires special attention, as it may indicate worsening hypothermia.
What to do for someone with hypothermia?
At the first signs of symptoms, move the person to a sheltered, warm place. Remove damp clothing and replace it with dry clothes. Cover the body with blankets, paying special attention to the trunk, and keep the person at rest.
If they remain fully conscious and can swallow normally, they may be given a warm drink. Warming must be gradual. Intense heat sources applied directly to the skin can cause injuries.
Call emergency services when there is confusion, intense drowsiness, altered consciousness, difficulty speaking, slow breathing, significant loss of coordination, or a decrease or cessation of shivering. These signs may indicate hypothermia that requires urgent medical assessment.
While waiting for assistance, keep the person warm and monitored. Transportation to a hospital or medical center should follow the instructions of emergency services or medical personnel. A person with altered consciousness requires professional attention and supervision throughout the process.
Early identification of symptoms facilitates rapid response. Shivering, cold skin, fatigue, and clumsiness can indicate the initial stages; confusion, drowsiness, altered consciousness, and slow breathing indicate a situation requiring urgent medical attention.
