- Sensors in the brain detect a lack of oxygen.
- The muscles in his body need more energy and therefore more oxygen.
The amount of oxygen in air and atmospheric pressure decreases with increase in altitude.
So, when Jon hikes up the hill he faces two problems; lack of oxygen in the air and decrease in atmospheric pressure.
Decreased atmospheric pressure makes it difficult for the lungs to breathe in the air and lack of oxygen decrease the blood oxygen level.
