We can protect ourselves from the wind with the right clothes, but is impossible to prevent the air from entering our body every single time that we breathe. At extreme altitudes, where Alex Txikon´s #wintertoappeal team lives, the air we breathe is extremely cold and dry. It does affect the respiratory mucous membrane, from the nostrils and throat to bronchus and lung alveoli. To reduce its side effects, hydration and vitamins are important. However, is also advisable to breathe using a scarf or other piece of cloth, as it warms up with our own breathing and filters the air before getting to the respiratory system. It is an ancestral and simple way of reducing the risk of suffering from some common diseases..
