5 Must Know Facts For Your Next Test

1. High altitude can lead to decreased oxygen availability, which may affect respiratory function.
2. Nutritional needs may change at higher altitudes due to increased metabolic rate and energy expenditure.
3. Hydration becomes crucial at high altitudes to prevent dehydration caused by increased respiration and fluid loss.
4. Iron-rich foods are essential at higher altitudes to support oxygen transport in the blood.
5. Individuals may experience altitude sickness, affecting nutrient absorption and overall health.
