Sep 9, 2021 · Visiting high-altitude locations may be dangerous for people with high blood pressure or certain heart conditions, according to a new report from the American Heart Association that offers guidance about engaging in recreational activities in mountainous regions.
Nov 15, 2023 · Altitude sickness occurs when a person travels to a high altitude — usually above 8,000 feet — without gradually acclimatizing. Symptoms such as weakness and nausea result from a lack of oxygen.
ACCLIMATISATION. Acclimatisation to altitude involves breathing faster & more deeply, and the heart pumping more blood to the brain & muscles. If you go to high altitude quickly, your body has to adapt to the thinner air and the lack of oxygen. Two important things happen almost immediately:
