Hypothermia – when body temperature is lowered to dangerous levels – can occur all too easily in the mountains and it's essential that climbers and walkers know how to avoid it and recognise it when they see the signs.
RISK FACTORS OF HYPOTHERMIA
First of all it's best to know when you might be making yourself even more vulnerable to hypothermia. Here are seven factors that can lead to a dangerous scenario:
 Sweating while ascending a mountain then cooling and not adding extra layers
 Remaining stationary on the hill without adequate clothing and protection
 Not fueling the body sufficiently with enough calories and fluids
 Going out when fighting off illness or lack of sleep/fatigue
 Wearing layers that don’t wick away moisture, such as cotton-based clothing which absorbs body sweat and moisture from the environment, leaving the wearer cold and damp.
 Failing to wear sufficient layering and windproof outer clothing to combat the effects of wind chill
MEASURES TO AVOID ITS ONSET
Once you've avoided the above risk factors you then need to be actively engaging in the prevention of hypothermia while on the go. Here's what you need to be doing:
 Always add an extra layer as you get higher up the mountain
 Swap your gloves for a dry pair when you have finished your ascent
 Always carry an additional large insulated jacket which will fit on over the top of everything you are wearing and put it on for lunch stops or any other time you're at risk of cooling, such as in descent.
 Make sure to eat enough. Even the best clothing can only keep heat in, not generate it.
SPOTTING THE SIGNS
Feeling cold and damp is obviously an early warning sign for hypothermia. A more subtle sign is laziness – not finding the effort to dig in your bag for an extra pair of clothes is an indication that you are not following the right rationale.
If these signs are unchecked, mild symptoms can then develop into irritability and irrational behaviour, poor decision making and, ultimately, collapse and even death.
