Many trekkers assume that being in good physical shape, strength training or running will prepare them for the expedition \u2014 but altitude has a mind of its own.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The body\u2019s ability to function in hypoxic conditions does not depend on fitness level, body type or trekking experience. It is largely individual and unpredictable. That is why it is so important to know how to tell whether your body is coping well with the altitude before symptoms of altitude sickness appear.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What does acclimatisation to altitude involve?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">As altitude increases, atmospheric pressure decreases, so each breath of air contains less oxygen. This causes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>rapid heartbeat<\/li>\n\n\n\n<li>increased respiratory rate<\/li>\n\n\n\n<li>greater fatigue<\/li>\n\n\n\n<li>appetite problems<\/li>\n\n\n\n<li>a decline in sleep quality<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The body must \u201elearn\u201d to function in conditions where there is less oxygen. This process is called acclimatisation and involves, amongst other things:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>an increase in the number of red blood cells<\/li>\n\n\n\n<li>more efficient use of oxygen by cells<\/li>\n\n\n\n<li>a change in the heart\u2019s rhythm<\/li>\n\n\n\n<li>a change in water and electrolyte balance<\/li>\n\n\n\n<li>improvement in respiratory function<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">It is during the acclimatisation period that you can tell whether you are predisposed to tolerate high altitudes well.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The key signs that your body is coping well with altitude<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1. No headache after reaching a new altitude<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A headache is the most common and first sign of AMS (acute mountain sickness). If, after ascending to a higher altitude:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>You don't have a headache<\/li>\n\n\n\n<li>you can\u2019t feel the throbbing<\/li>\n\n\n\n<li>you don\u2019t feel any pressure behind your eyes<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">\u2014 this is a sign that the body is coping with a lack of oxygen.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Stable breathing and resting heart rate<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">At high altitudes, your heart beats faster, but if:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>the heart rate is not drastically elevated,<\/li>\n\n\n\n<li>my breathing becomes calmer with every passing hour,<\/li>\n\n\n\n<li>you don\u2019t feel as though you\u2019re \u201erunning out of breath\u201d whilst resting,<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">\u2014 this means that the adaptation is proceeding as it should.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. A healthy appetite<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Loss of appetite is one of the most common symptoms of AMS. If you\u2019re eating normally or even feeling hungry, these are very good signs. A body that copes well with altitude demands calories because it uses them efficiently.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. No nausea, loss of appetite or vomiting<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Nausea in the mountains is a warning sign. The absence of it means:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>metabolic balance<\/li>\n\n\n\n<li>the proper functioning of the nervous system<\/li>\n\n\n\n<li>no cerebral oedema at an early stage<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If you don\u2019t have any stomach problems \u2014 that\u2019s a big plus for your acclimatisation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. A steady supply of energy whilst trekking<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Being able to cope well with heights means that you do not:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>sudden drops in energy levels<\/li>\n\n\n\n<li>\u201eheavy legs\u201d<\/li>\n\n\n\n<li>shortness of breath on a gentle incline<\/li>\n\n\n\n<li>excessive sleepiness<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Your body is capable of functioning effectively, even when oxygen levels drop.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6. Getting a good night\u2019s sleep at 3,000\u20134,500 metres<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Sleep problems are very common, but if:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>you go to sleep at a reasonable time,<\/li>\n\n\n\n<li>you don\u2019t wake up feeling short of breath,<\/li>\n\n\n\n<li>you don\u2019t have nightmares or \u201ealtitude snow\u201d,<\/li>\n\n\n\n<li>you feel refreshed in the morning,<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">\u2014 this is a clear sign that your body is adapting to the altitude.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">7. No signs of \u201edrunken balance\u201d<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Walking in a straight line is an important neurological test. If:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>you\u2019re walking steadily,<\/li>\n\n\n\n<li>you don\u2019t feel dizzy,<\/li>\n\n\n\n<li>you don\u2019t sway from side to side,<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">\u2014 the nervous system does not react abnormally to altitude.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What else indicates a good tolerance for altitude?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A small number of mild headaches<br>Mild aches and pains are normal, but if they\u2019re minor and go away quickly \u2014 that\u2019s great.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Good hydration<br>An organism that copes well with altitude does not \u201ereject\u201d water, but absorbs it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Mental balance<br>At high altitudes, people can become irritable or listless. If you feel calm, that\u2019s a good sign.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Normal body temperature<br>The absence of a fever is a sign that your metabolism is functioning normally.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Tests and signs that you can aim higher<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">You can assume that acclimatisation is working if, after climbing 300\u2013500 metres higher:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>you feel much the same as you did the day before<\/li>\n\n\n\n<li>you don\u2019t have a headache after 1\u20132 hours<\/li>\n\n\n\n<li>you don\u2019t feel short of breath when you\u2019re resting<\/li>\n\n\n\n<li>you have a normal appetite<\/li>\n\n\n\n<li>the heart rate returns to normal after resting<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If all the above points are met, you can carry on with the trek as planned.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">And when does that mean you CAN\u2019T stand heights?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">As well as the positive signs, it\u2019s worth being aware of the negative ones:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The headache doesn\u2019t go away after drinking water and resting<\/li>\n\n\n\n<li>no appetite at any time of day or night<\/li>\n\n\n\n<li>nausea or vomiting<\/li>\n\n\n\n<li>insomnia lasting several nights<\/li>\n\n\n\n<li>heart palpitations<\/li>\n\n\n\n<li>dizziness<\/li>\n\n\n\n<li>balance problems<\/li>\n\n\n\n<li>irritability and confusion<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This means that your body is struggling, so you should take a break or go down to a lower altitude.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Is it possible to predict whether someone will cope well with heights?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Unfortunately \u2014 no.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A good tolerance for altitude does NOT depend on:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>age<\/li>\n\n\n\n<li>gender<\/li>\n\n\n\n<li>training placement<\/li>\n\n\n\n<li>VO\u2082 max<\/li>\n\n\n\n<li>body fat percentage<\/li>\n\n\n\n<li>muscle strength<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Every body reacts differently. The best method is:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>a gradual ascent,<\/li>\n\n\n\n<li>observation,<\/li>\n\n\n\n<li>following the acclimatisation guidelines,<\/li>\n\n\n\n<li>early response to symptoms.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How can you improve your altitude tolerance? (Yes, it is possible!)<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1. \u201eGradual\u201d acclimatisation\u201d<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The most effective method \u2014 gaining altitude slowly in accordance with the \u201e300\u2013500 m\u201d rule.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Climbing higher during the day<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Starting with an ascent and then descending speeds up adaptation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Diamox (after consulting a doctor)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It supports adaptation, but does not replace it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Water intake: 3\u20134 litres a day<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Water speeds up metabolic processes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Eating regularly<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The body needs energy to function at high altitudes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6. Avoiding alcohol<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Alcohol slows down acclimatisation and dehydrates the body.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Summary<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Good altitude tolerance is a combination of biological predisposition, proper acclimatisation, listening to your body and making responsible decisions. You can consider that your body copes well with altitude if:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>you don\u2019t have a headache,<\/li>\n\n\n\n<li>you breathe calmly,<\/li>\n\n\n\n<li>you\u2019ve got an appetite,<\/li>\n\n\n\n<li>you sleep more or less normally,<\/li>\n\n\n\n<li>you feel a steady flow of energy,<\/li>\n\n\n\n<li>you don\u2019t have any balance problems,<\/li>\n\n\n\n<li>there is no nausea.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">It is precisely these signals that show your body is capable of functioning in conditions of low oxygen levels, and that you can continue trekking without any worries. But what if you experience any adverse symptoms? The rule is simple: slow down, rest or head downhill. In the mountains, it\u2019s not the person who walks the fastest who wins \u2014 it\u2019s the one who listens to their body.<\/p>","protected":false},"excerpt":{"rendered":"<p>Dobre znoszenie wysoko\u015bci to jedna z najcenniejszych cech podczas trekking\u00f3w w Himalajach i wsz\u0119dzie tam, gdzie szlaki prowadz\u0105 powy\u017cej 3000\u20133500 m n.p.m. Wielu trekker\u00f3w zak\u0142ada, \u017ce wysoka kondycja, trening si\u0142owy czy bieganie przygotuj\u0105 ich do wyprawy \u2014 ale wysoko\u015b\u0107 rz\u0105dzi si\u0119 w\u0142asnymi prawami.
