Hypothermia in the mountains<\/strong> is one of the most insidious life-threatening conditions you can encounter beyond civilization. Unlike altitude sickness, it doesn’t announce itself with dramatic symptoms \u2014 it starts quietly, with shivering and fatigue, and once it crosses a certain threshold, the victim often stops cooperating and doesn’t realize they’re in mortal danger<\/em>. As an expedition doctor who has led mountain medicine workshops at COSY Outdoor Festival and “Lawiny” Mountain Meetings in Poland, I have repeatedly seen how quickly a situation can spiral out of control for a group that “just wanted to rest for a moment” below a pass.<\/p>\n\n\n\n

In this guide I will walk you through exactly what happens to the body during hypothermia, how to recognize the four stages of cooling according to the Swiss Staging classification<\/strong>, how to administer first aid step by step \u2014 and above all: what you must absolutely never do<\/strong>. This article is written from the perspective of a practitioner who learns mountain medicine on real people in the field, not in a lecture hall.<\/p>\n\n\n\n

Hypothermia kills in the mountains more often than statistics suggest \u2014 many cases are classified as “exhaustion” or “trauma” while the actual cause of death was a drop in core body temperature below the critical threshold<\/strong>. According to European Resuscitation Council data, hypothermia victims in extreme weather represent a significant percentage of all deaths during winter hikes and high-altitude expeditions. Knowing the signs of hypothermia and being able to isolate a casualty from wind and cold ground are in practice the two most important skills for anyone walking in the mountains in winter.<\/p>\n\n\n\n

TL;DR \u2014 key facts<\/h4>\n\n\n\n
    \n
  • Hypothermia is a drop in core body temperature below 35\u00b0C (95\u00b0F)<\/strong>. Not “feeling cold” \u2014 but the body losing thermoregulatory control.<\/li>\n
  • The four Swiss Staging stages (HT I\u2013IV) differ very concretely: presence of shivering, consciousness, pulse, breathing \u2014 that’s your decision map in the field.<\/li>\n
  • The most dangerous is the transition from HT I to HT II<\/strong>: shivering stops, the body ceases producing heat. Many people think “I’m feeling better” \u2014 and that’s exactly when things get really bad.<\/li>\n
  • In the field the rule is “no pulse, no breathing, no rewarming in field”<\/strong> \u2014 if vital functions are uncertain, do not aggressively rewarm and do not abandon resuscitation.<\/li>\n
  • An emergency blanket (NRC foil), a 2-person bothy bag, and a dry set of base layers are the three things that really save lives \u2014 expensive “technological” bandages are far less important here.<\/li>\n<\/ul>\n\n\n\n

    What exactly is hypothermia?<\/h2>\n\n\n\n

    Hypothermia<\/strong> is a condition in which core body temperature falls below 35\u00b0C (95\u00b0F). You don’t measure it under the armpit or in the ear \u2014 those readings are useless<\/em> in the field with a hypothermic person. Real core temperature is assessed with a rectal thermometer, and in hospital settings via an esophageal thermometer. In the mountains we assess clinical presentation: how the casualty looks, whether they shiver, how they breathe, whether they are conscious.<\/p>\n\n\n\n

    The human body operates within a very narrow thermal range \u2014 so-called normothermia<\/strong> is 36.5\u201337.5\u00b0C (97.7\u201399.5\u00b0F). When core temperature drops, defense mechanisms activate: peripheral vasoconstriction (pale hands and feet), muscle shivering (heat production from muscle work), increased pulse and blood pressure. This stage is the adaptive response<\/em> \u2014 the body tries to cope. The problem is that its resources are limited: muscle glycogen stores last for several hours of intense shivering, then the “battery” runs out.<\/p>\n\n\n\n

    Who is most at risk of hypothermia in the mountains<\/h3>\n\n\n\n
      \n
    • Inexperienced hikers<\/strong> who head into winter mountains in inadequate clothing (cotton, no windproof outer layer) \u2014 the most common category of hypothermia victims.<\/li>\n
    • Children and elderly<\/strong> \u2014 worse thermoregulation, less muscle mass for shivering-based heat production. In children, low body temperature develops 2\u20133 times faster than in adults.<\/li>\n
    • Injury casualties<\/strong> (fall, avalanche burial, fracture) \u2014 immobilization plus exhaustion plus often wet clothing is a recipe for hypothermia within an hour.<\/li>\n
    • Intoxicated individuals<\/strong> \u2014 impaired judgment, disturbed thermoregulation, classic deaths “on the way down from the hut”.<\/li>\n
    • Climbers and rescuers working in extreme conditions<\/strong> \u2014 prolonged exposure to cold, wind and exhaustion, often without immediate possibility to descend.<\/li>\n<\/ul>\n\n\n\n

      Mountain weather can change within minutes \u2014 even a summer trip above 2500 m can end in hypothermia. That is why, for every trip above the tree line, I pack a windproof jacket, a hat and an emergency blanket regardless of the forecast.<\/p>\n\n\n\n

      The mechanism of cooling in the mountains \u2014 why it’s so dangerous here<\/h2>\n\n\n\n

      In the mountains we lose heat through four pathways, each more aggressive than in the valley:<\/p>\n\n\n\n

        \n
      1. Conduction<\/strong> \u2014 contact with cold ground, wet clothing, ice. That’s why sitting on a rock “just for five minutes” after a sweaty uphill can cool you more than two hours of walking.<\/li>\n
      2. Convection<\/strong> \u2014 wind. Windchill effect can be brutal: at -5\u00b0C with 40 km\/h wind, perceived temperature drops to roughly -18\u00b0C. On an Alpine ridge that’s standard, not extreme.<\/li>\n
      3. Evaporation<\/strong> \u2014 sweat and wet clothing. That’s why “don’t overheat on the ascent” isn’t a whim \u2014 a sweaty shirt becomes, hours later, a cooling unit stuck to your body.<\/li>\n
      4. Radiation<\/strong> \u2014 exposed skin emits infrared into the environment. Head, neck and face lose enormous amounts of heat because they are most vascularized.<\/li>\n<\/ol>\n\n\n\n

        Add altitude<\/strong>, which lowers blood oxygen saturation and impairs peripheral circulation, dehydration<\/strong>, which thickens the blood, and physical exhaustion<\/strong>, which depletes glycogen reserves \u2014 and you have a recipe for hypothermia within hours, not days.<\/p>\n\n\n\n

        Four stages of hypothermia \u2014 Swiss Staging classification<\/h2>\n\n\n\n

        In mountain medicine we use the classification developed by Swiss rescuers and endorsed by ICAR MEDCOM<\/strong> (International Commission for Alpine Rescue). This scale is based on clinical observation, not on an exact thermometer \u2014 which is critically important in the field.<\/p>\n\n\n\n

        Stage<\/th>Core temp.<\/th>Consciousness<\/th>Shivering<\/th>Decision<\/th><\/tr><\/thead>
        HT I<\/strong> (mild)<\/td>35\u201332\u00b0C<\/td>Conscious, often anxious<\/td>Present<\/strong>, intense<\/td>Insulate, warm drinks, movement<\/td><\/tr>

        Swiss Staging hypothermia classification \u2014 ICAR MEDCOM<\/figcaption><\/figure>\n\n\n\n

        HT I \u2014 mild hypothermia (35\u201332\u00b0C)<\/h3>\n\n\n\n

        This is the state most of us recover from without harm \u2014 if we recognize it in time<\/strong>. The casualty is conscious but irritable, complains of cold, has intense shivering, pale and cyanotic skin. Often refuses to rest \u2014 “I want to keep going, movement will warm me up”. Sometimes right, more often wrong. At this stage shivering is our ally: muscles produce up to 5 times more heat than at rest. But they need fuel \u2014 if the casualty is hungry and dehydrated, shivering will stop quickly.<\/p>\n\n\n\n

        HT II \u2014 moderate hypothermia (32\u201328\u00b0C)<\/h3>\n\n\n\n

        Here things get truly dangerous. Shivering stops<\/strong> \u2014 paradoxically, many expedition members think at that point “I feel better now”. In reality the body has exhausted its glycogen reserves and is giving up. Apathy appears, slowing of movements, slurred speech, loss of coordination (classic test: ask them to tie their bootlaces \u2014 they won’t manage). The famous “paradoxical undressing”<\/strong> is a symptom of this stage \u2014 a hypothermic person in disorientation starts removing their jacket because they feel hot. In the Alps and Tatras every year bodies are found in winter partially undressed \u2014 that’s not “madness”, it’s a neurological effect of cooling.<\/p>\n\n\n\n

        HT III \u2014 severe hypothermia (28\u201324\u00b0C)<\/h3>\n\n\n\n

        The casualty is unconscious but still has a palpable pulse and breathing. Both are slow, irregular, hard to count \u2014 according to ICAR\/ERC guidelines assess pulse for at least 60 seconds<\/strong> (in normothermia 10 seconds is enough). Arrhythmia, ectopic beats and bradycardia are the norm at this stage. Any careless movement, jolt, or unnecessary chest compression can trigger ventricular fibrillation \u2014 so you treat a person in HT III like a “raw egg”.<\/p>\n\n\n\n

        HT IV \u2014 extreme hypothermia (<24\u00b0C), “apparent death”<\/h3>\n\n\n\n

        No pulse, no breathing, pupils may be dilated. But \u2014 and this is key \u2014 it doesn’t mean the casualty is dead<\/strong>. In deep hypothermia metabolism slows so much that the brain can survive an hour without circulation. The literature describes cases of full neurological recovery after resuscitation lasting over 6 hours. Hence the classic wilderness medicine rule: “Nobody is dead until warm and dead”<\/em>. If you see a person in HT IV in the field, you start CPR and don’t stop until you hand over to mountain rescue or the patient reaches core temperature of 32\u00b0C in hospital.<\/p>\n\n\n\n

        First aid in hypothermia \u2014 step-by-step algorithm<\/h2>\n\n\n\n

        At mountain medicine workshops I always repeat one thing: first stop further heat loss, only then think about rewarming<\/strong>. It sounds trivial, but 80% of field mistakes consist of trying to “warm up” the casualty before stopping wind, moisture and contact with cold ground. In hypothermia first aid the rule also applies \u2014 call for help immediately<\/strong>. Dial emergency services (112 in Europe, 911 in the US) or mountain rescue before you start medical action, because rescue comes to you, while you may not manage to descend with the casualty in reasonable time.<\/p>\n\n\n\n

        1. Shelter and insulation<\/h3>\n\n\n\n

        Isolate the casualty from wind and ground. In the field we use an emergency 2-person bothy bag<\/strong> \u2014 a floorless shelter of bright material that both you and the casualty enter. The breath of two people alone can raise internal temperature by 10\u201315\u00b0C within minutes. This is, in my opinion, the most important winter gear after the first aid kit \u2014 and costs less than a good pair of gloves. Alternative: an emergency blanket (NRC foil)<\/strong> placed under the casualty as insulation from the ground (the aluminized side facing the body doesn’t matter \u2014 what counts is the barrier against wind and moisture).<\/p>\n\n\n\n

        Despite the trend that emergency blankets are “pass\u00e9”, I maintain they are among the most versatile elements of any first aid kit \u2014 waterproof, durable, compact, and you can build improvised stretchers, canopy over a wound, wind shelter. At “Lawiny” and COSY workshops I demonstrated how to create a full shelter for two people with an NRC blanket \u2014 the trick is to get inside together and tie it from below with a backpack strap.<\/p>\n\n\n\n

        2. Remove wet clothing<\/h3>\n\n\n\n

        Wet clothing accelerates cooling several times over<\/strong>. Even the best down, once wet, loses about 80% of its insulating capacity. In the field: cut wet base layers with scissors (hence my rule from workshops \u2014 scissors that actually cut, not plastic toys from a market<\/em>), dry the casualty with a towel, dress them in dry layers. If you have no dry change \u2014 a dry sleeping bag and NRC foil are better than a soaked jacket.<\/p>\n\n\n\n

        3. Hypothermia wrap \u2014 emergency burrito<\/h3>\n\n\n\n

        The hypothermia wrap<\/strong> (sometimes called “burrito wrap”) is the gold standard of mountain rescue. Layer order from outside to inside:<\/p>\n\n\n\n

          \n
        1. Windproof\/waterproof layer (NRC foil, tarp, bivy)<\/li>\n
        2. Insulating layer (sleeping pad, backpack, down clothing)<\/li>\n
        3. Sleeping bag (ideally warm, e.g. comfort rating -10\u00b0C)<\/li>\n
        4. Casualty in dry base layer, with a hat and warm socks<\/li>\n
        5. Active heating on chest and neck (hot water bottles, warm water flasks, chemical heat packs)<\/li>\n<\/ol>\n\n\n\n

          Do not add heat packs to hands and feet \u2014 peripheral vasodilation causes cold blood to flow from the limbs into the heart (afterdrop phenomenon<\/strong>), which may trigger arrhythmia. Warm centrally<\/strong>: chest, neck, armpits, groin.<\/p>\n\n\n\n

          4. Warm drinks \u2014 only for HT I<\/h3>\n\n\n\n

          Warm tea with glucose (not “hot”, as it may burn impaired swallowing reflexes), ideally sweetened \u2014 fuel for shivering. Key warning:<\/strong> only give fluids to a conscious patient who can safely swallow<\/strong>. A person with HT II or lower gets nothing by mouth \u2014 aspiration risk outweighs benefits. Alcohol is forbidden<\/strong>: it dilates skin vessels, amplifies the feeling of warmth, and in reality accelerates core temperature loss and impairs judgment.<\/p>\n\n\n\n

          5. Evacuation<\/h3>\n\n\n\n

          HT I \u2014 often the casualty can descend on their own after half an hour of shelter and food. HT II+ \u2014 mandatory evacuation, ideally by helicopter (mountain rescue services). Until rescue arrives \u2014 minimize every movement of the casualty<\/strong>. Any jolt can trigger ventricular fibrillation in a person with core temperature below 28\u00b0C.<\/p>\n\n\n\n

          What you must NEVER do<\/h2>\n\n\n\n
            \n
          • Rubbing with snow or chafing skin<\/strong> \u2014 Hollywood myth. Causes additional damage and local hypothermia.<\/li>\n
          • Hot baths or hot showers<\/strong> \u2014 dramatic peripheral vasodilation, afterdrop, cardiac arrest. Controlled warming is done in hospital \u2014 never in the field.<\/li>\n
          • Alcohol<\/strong> \u2014 explained above. “A shot of brandy to warm up” is one of the most persistent alpinist myths and one of the most harmful.<\/li>\n
          • Massage or vigorous rubbing of limbs<\/strong> \u2014 same afterdrop risk.<\/li>\n
          • Aggressive rewarming in the field without monitoring<\/strong> \u2014 exception: HT I patient, fully conscious, reliable access to warm shelter. Otherwise the rule “no pulse, no breathing, no rewarming in field”<\/em> applies.<\/li>\n
          • Premature declaration of death<\/strong> \u2014 in deep hypothermia pupils may be dilated, pulse absent, skin cold and cyanotic. You start CPR and continue until rescue arrives.<\/li>\n<\/ul>\n\n\n\n

            Resuscitation in hypothermia \u2014 how it differs from “standard” CPR<\/h2>\n\n\n\n

            The BLS\/ALS algorithm in hypothermia has several crucial modifications per European Resuscitation Council (ERC)<\/strong> and ICAR guidelines:<\/p>\n\n\n\n

              \n
            • Pulse assessment for 60 seconds<\/strong> (instead of 10) \u2014 hypothermic bradycardia can produce 1\u20132 beats per minute.<\/li>\n
            • Prolonged resuscitation<\/strong> \u2014 in HT IV, CPR often lasts 60\u2013240 minutes before effect. Until at least 32\u00b0C core is reached, “irreversibility” is not assessed.<\/li>\n
            • Defibrillation<\/strong> \u2014 allowed but often ineffective below 30\u00b0C. Guidelines: try up to 3 times, then wait for rewarming to 30\u00b0C and resume.<\/li>\n
            • Medications<\/strong> \u2014 adrenaline and amiodarone are less effective in hypothermia; not available in field conditions. Focus on CPR quality and rewarming.<\/li>\n
            • Transport to ECMO center<\/strong> \u2014 in HT III\/IV with cardiac arrest the target hospital must have ECMO\/CRRT capability (extracorporeal circulation). Communicate this to the rescue coordinator the moment you call for help.<\/li>\n<\/ul>\n\n\n\n

              Preventing hypothermia \u2014 the three-layer strategy<\/h2>\n\n\n\n

              The best treatment is prevention, and prevention in the mountains starts with the layered clothing system<\/strong>. Three layers isn’t fashion, it’s physics:<\/p>\n\n\n\n

                \n
              1. Base layer<\/strong> \u2014 wicks moisture from skin. Merino (180\u2013250 g\/m\u00b2) or quality synthetics. Cotton is forbidden<\/strong> \u2014 once wet, it won’t dry in winter conditions and will literally freeze you. In wilderness medicine the saying is “cotton kills”.<\/li>\n
              2. Mid layer (insulating)<\/strong> \u2014 fleece, softshell, lightweight down (700+ fill power). Its job is to trap heat. In winter in the mountains, often two such layers depending on movement intensity.<\/li>\n
              3. Shell layer<\/strong> \u2014 wind- and waterproof. A membrane (Gore-Tex, eVent, Pertex) or full down when cold and dry. This layer doesn’t insulate \u2014 it protects against wind and precipitation.<\/li>\n<\/ol>\n\n\n\n

                Add gloves (always a spare pair!), a hat, buff\/neck gaiter \u2014 and about hats I tell expedition members that a hat is the most important clothing item at night<\/strong>. The head radiates enormous amounts of heat, and a sleeping bag insulates the body, not the head. At Everest Base Camp in 2022 we all slept in hats even at 5364 m. Without a hat you wake up with a headache and sinus pain \u2014 it’s not a matter of comfort, it’s a matter of thermoregulation.<\/p>\n\n\n\n

                Hypothermia after avalanche burial \u2014 a special case<\/h2>\n\n\n\n

                An avalanche victim is exposed to the avalanche triad<\/strong>: asphyxia, mechanical trauma, and hypothermia \u2014 in that order as causes of death. The cooling rate in snow is approximately 3\u00b0C per hour<\/strong>. This means a victim buried 30 min after extraction is usually still in HT I, but after 60\u201390 min may already be in HT II, and after 3 h in HT III. That is why ICAR guidelines speak of the “golden 15 minutes”: survival chances for burial longer than 35 minutes drop sharply, mainly due to asphyxia, with hypothermia as the second factor.<\/p>\n\n\n\n

                After extraction: avoid sudden movements, assess per Swiss Staging, apply hypothermia wrap, transport to ECMO if HT III\/IV. I cover avalanche triage and MEDCOM algorithm in detail in a separate article on avalanche medicine.<\/p>\n\n\n\n

                My experience \u2014 COSY Outdoor Festival and “Lawiny” workshops<\/h2>\n\n\n\n

                At mountain medicine workshops for women at COSY Outdoor Festival and at “Lawiny” Mountain Meetings I always ran one exercise that changes participants’ approach forever: a hypothermia simulation. One person plays the cooled casualty (unresponsive, showing HT II signs), the group has 20 minutes to build a hypothermia wrap. Afterwards we debrief the mistakes.<\/p>\n\n\n\n

                The most common error \u2014 and this is not limited to beginners, it affects professional rescuers too \u2014 is haste in rewarming<\/strong>. People instinctively want to “do something”: give hot tea, rub hands, wrap heat packs on the feet. All of this causes harm. The rule from my workshops that I repeat endlessly: first insulate and stop heat loss, then think about warming<\/em>. Being a simulation victim once teaches you forever that hypothermia is handled first, fracture second.<\/p>\n\n\n\n

                The second thing I teach participants \u2014 gear that actually works, not props<\/strong>. Your first aid scissors must actually cut through a thick fleece and membrane. The 2-person bothy bag must be tested before the trip, not during the crisis. Silver duct tape is more valuable than an expensive elastic bandage \u2014 it’s stronger, more universal, works on wet surfaces. In mountain medicine, improvisation from what you have is often better than searching for a “professional” solution.<\/p>\n\n\n\n

                Frequently asked questions<\/h2>\n\n\n
                \n
                \n
                \n

                At what body temperature does hypothermia begin?<\/h3>\n
                \n\n

                Hypothermia is a drop in core body temperature below 35\u00b0C (95\u00b0F). The Swiss Staging classification (ICAR MEDCOM) divides it into four stages: HT I (35\u201332\u00b0C, mild, with shivering), HT II (32\u201328\u00b0C, moderate, shivering stops), HT III (28\u201324\u00b0C, severe, unconscious with preserved vital signs), HT IV (<24\u00b0C, extreme, apparent death). Armpit or ear measurement is useless in the field \u2014 clinical assessment is what counts.<\/p>\n\n<\/div>\n<\/div>\n

                \n

                Why do hypothermic people undress themselves?<\/h3>\n
                \n\n

                This phenomenon is called paradoxical undressing and occurs in moderate hypothermia (HT II, 32\u201328\u00b0C). Due to severe thermoregulatory dysfunction the brain receives false information about overheating \u2014 the victim feels a rush of warmth and intuitively removes clothing. The neurological mechanism involves failure of peripheral vasoconstriction \u2014 blood suddenly rushes to the skin, producing a false sensation of warmth. This is a sign that hypothermia is advanced and requires immediate evacuation.<\/p>\n\n<\/div>\n<\/div>\n

                \n

                Can you give a hot drink to a hypothermic person in the mountains?<\/h3>\n
                \n\n

                Yes, but only in mild hypothermia (HT I), when the casualty is conscious and able to swallow safely. You give a warm (not hot!) tea with sugar or electrolyte solution \u2014 fuel for shivering. In HT II and below, nothing is given by mouth \u2014 aspiration risk outweighs benefits. Alcohol is strictly forbidden at every stage \u2014 it dilates skin vessels, accelerates core heat loss, impairs judgment, and worsens hypothermia.<\/p>\n\n<\/div>\n<\/div>\n

                \n

                What is afterdrop and how to avoid it?<\/h3>\n
                \n\n

                Afterdrop is the paradoxical fall in core temperature (heart, brain) after rewarming begins. It occurs when cold peripheral blood rushes back to the trunk after vasodilation. It can trigger ventricular fibrillation and cardiac arrest. That is why in the field we rewarm only centrally (chest, neck, armpits, groin), we do not place heat packs on feet or hands, we avoid hot baths and sudden casualty movements. In hospital settings ECMO provides controlled rewarming for HT III\/IV patients.<\/p>\n\n<\/div>\n<\/div>\n

                \n

                When can you stop resuscitating a hypothermic person?<\/h3>\n
                \n\n

                The rule is \u201dnobody is dead until warm and dead\u201d. In deep hypothermia metabolism is so slowed that the brain can survive an hour without circulation. ICAR\/ERC guidelines recommend continuing CPR until rescue hand-over or until core temperature of at least 32\u00b0C is achieved in hospital. The literature describes cases of full neurological recovery after resuscitation lasting over 6 hours. The decision to stop is made by an ICU physician, not by a rescuer in the field.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n
