10 Altitude Sickness Symptoms
Reviewed: Dr. Gromatzky
Symptom #5: Dizziness
The brain needs a constant supply of oxygen and nutrients in order to function. If there is not enough oxygen in the air, the brain soon feels the impact. A lack of oxygen makes people feel dizzy, and they can struggle with their coordination as a result.
Dizziness is a pretty sure sign that someone is suffering from altitude sickness. People should either slow the rate of ascent or stop climbing.
