What is Hypothermia and How to Successfully Avoid It
Hypothermia - The Hidden Enemy That Can Threaten Any of Us
Hypothermia, technically known as hypothermia, is a condition where a person's body temperature drops below 35 °C. It is a serious and potentially life-threatening issue that can occur not only in extreme conditions but also in cold weather if the body loses its ability to regulate temperature. This condition is usually associated with prolonged exposure to cold, but there are a number of factors that can contribute to its onset. What exactly is hypothermia, what are its causes, symptoms, and what can we do to avoid it?
What is hypothermia and why does it occur?
Hypothermia occurs when the body loses heat faster than it can produce it. The human body naturally maintains a temperature of around 37 °C through metabolism, movement, or shivering, which generates heat. However, in adverse conditions such as frost, strong winds, or rain, the body cannot maintain this balance. Hypothermia can be caused by inappropriate clothing, prolonged exposure to cold, or wet layers that multiply heat loss. This condition is further exacerbated by fatigue, hunger, poor blood circulation, or alcohol consumption, which paradoxically, although causing a feeling of warmth, actually speeds up heat loss.
Conditions leading to hypothermia can arise not only in the mountains or during outdoor activities but even in the city, for example, during long waits at a bus stop or staying in unheated spaces. The risk further increases for vulnerable groups such as the elderly, children, or the homeless.
How does hypothermia manifest?
Hypothermia usually develops gradually, and its symptoms can initially be subtle. It often manifests as shivering, a natural response of the body to a drop in temperature. However, when hypothermia progresses, shivering stops, which paradoxically indicates a worsening condition. Early symptoms include feeling cold, decreased sensitivity of the limbs, and slowed reflexes. As hypothermia progresses, confusion, disorientation, loss of coordination, and fatigue occur. Without prompt assistance, the condition can lead to unconsciousness and, in the worst case, failure of vital organs.
How to prevent hypothermia?
Preventing hypothermia begins with proper preparation. The key is layered clothing, combining a base functional layer that wicks away sweat, an insulating layer for warmth, and an outer protective layer against wind and water. Dry shoes, gloves, and hats are essential, as the head and extremities are areas of the body where most heat escapes.

Another important factor is movement, which helps generate heat and maintain blood circulation, but it should not lead to exhaustion. A diet rich in carbohydrates and fats provides the body with the energy needed for thermoregulation, while adequate hydration supports metabolism function. However, avoid alcohol, which can cause vasoconstriction and faster heat loss.
Dietary supplements as a prevention of hypothermia
Certain dietary supplements can be useful for improving the body's ability to withstand cold. B vitamins are essential for the efficient conversion of food into energy, while minerals such as magnesium and zinc support proper blood circulation. Omega-3 fatty acids improve vascular flexibility, which is important for retaining heat in the extremities. Ginger or adaptogens such as ginseng also strengthen immunity and contribute to warming the body.

First aid for hypothermia
If you find yourself in a situation where someone shows signs of hypothermia, it is important to act quickly. First, move the affected person to a dry place protected from the wind. Wet clothing needs to be immediately replaced with dry layers covering the entire body, including the head. Mild hypothermia can be addressed by providing warm drinks and energy-rich foods, while in more severe cases, medical help is essential.
Hypothermia is a condition that can affect anyone who underestimates preparation or misjudges the risks associated with cold. Proper clothing, adequate energy intake, and timely response to hypothermia symptoms can save a life. When planning outdoor activities, whether in nature or in the city, always remember that prevention is the best way to avoid dangerous consequences. Be prepared, respect nature, and above all, take care of your health, which is the greatest value.
