Quick Answer
The first signs of hypothermia in survival situations include shivering, confusion, and difficulty speaking. These symptoms often appear when the body's core temperature drops below 95°F (35°C). Early recognition of hypothermia is crucial to preventing its progression.
Identifying Hypothermia Symptoms
Recognize hypothermia symptoms early by understanding the psych rule of threes. In most cases, hypothermia symptoms appear in three stages. Stage one is evident when the body shivers uncontrollably. Shivering is a natural response to cold temperatures, but in hypothermia, it’s a sign that the body is struggling to regulate its core temperature. The American Red Cross estimates that the average shivering person can lose up to 50% of their body heat within 30 minutes.
Assessing Hypothermia Severity
Assess the severity of hypothermia by evaluating the person’s level of consciousness. Stage two hypothermia is characterized by confusion, disorientation, and difficulty speaking. At this stage, the person’s cognitive functions are impaired, making it challenging for them to make rational decisions. In stage two, the person’s body temperature is typically below 90°F (32°C). Use the acronym CHECK to remember the essential signs of hypothermia: C – Confusion, H – Hypotension, E – Excessive shivering, C – Cyanosis, K – Kidney failure, and K – Kidney failure.
Preventing Hypothermia Progression
Prevent hypothermia progression by providing the person with warm clothing, a dry place to sit, and a source of warmth. In severe cases, use the buddy system to keep the person warm. The buddy system involves having one person sit on either side of the hypothermic person, ensuring that their body heat is transferred to the person in need. This technique can help raise the person’s body temperature by 1-2°F (0.5-1°C) per hour.
