But when we rapidly transfer to these elevations, you possibly can develop medical issues, mostly altitude illness,” Dr. Hermann shares. By progressively getting used to excessive elevations—maybe by settling at a base camp for a number of days earlier than venturing as much as greater factors and peaks—you possibly can scale back your probabilities of feeling sick or out of kinds.

Based on Dr. Hermann, the commonest signs of altitude illness embrace nausea, vomiting, and headache, that are “typically delicate and often resolve inside a few days.” Nonetheless, in case you expertise extra extreme signs—together with chest tightness, intense issue respiration, and stability or coordination points, he advises in search of instant medical consideration.
