10 Altitude Sickness Symptoms
Symptom #4: Aching Muscles
The muscles need a constant supply of oxygen to help them function. The harder they work, the more oxygen they need in order to operate as efficiently as possible. However, when there is not enough oxygen around, complications can develop.
When climbing in high altitudes, the muscles are likely already working hard, requiring more oxygen than usual. The insufficient amount of oxygen in the air combined with a lack of red blood cells to deal with higher altitudes exacerbates the problem. The muscles start to ache, making it harder to keep moving.
