Gradual2
- This illness almost always has a gradual onset and gets worse slowly over several hours. (kingstontravel.ca)
- Gradual hiking up combined with allowing sufficient rest at various intermediate altitudes will give your body time to adapt and acclimatize better to areas with decreased air pressure. (camotrek.com)
Exposure2
- Having a high-altitude exposure at more than 9,000 ft (2,750 m) for 2 nights or more, within 30 days before the trip, is useful. (kingstontravel.ca)
- The cardiovascular changes at high altitude are influenced by factors such as population ancestry and sociocultural determinants, as well as adaptation, nutrition, intercurrent infection, exposure to pollutants and toxins, socioeconomic status, and access to medical care. (medscape.com)
