Preventive Search and Rescue
Hypothermia is deadly. There, I said it! This potentially dangerous drop in body temperature is commonly defined as a core body temperature below 95 degrees Fahrenheit (35 degrees Celsius) after dropping from a healthy temperature of about 98.6 degrees Fahrenheit or 37 degrees Celsius.
The slightest variance from the “normal” range can disrupt the body’s ideal operating conditions, known as homeostasis. The negative impact of hypothermia on homeostasis is dramatic and therefore should not be underestimated. Hypothermic progression follows a path, moving first more slowly, then more rapidly toward non-movement and when properly treated, onto death.
Movement is life. Living things grow, evolve, learn and work to improve their circumstances. Non-living things hold fast to current circumstances unless acted upon by an outside force. As we’ve all experience, movement generates warmth, and this case, it combats hypothermia. A creature that has the appropriate amounts of items necessary for movement will generally maintain a body temperature conducive for life.
These items required for movement include nutrients, health, fitness, clothing, and sometimes technical outdoor tools such as an ice axe and crampons. A breakdown of these items leads to decreased movement and reduced temperature. In this post, we will look at the hypothermic process using the five umbles: (more…)
