With the increase in altitude, the level of oxygen decreases.
Thus, when a man goes up to a hill he gets less of oxygen in the lungs for diffusion in blood.
Moreover, the heart beat increases to increase the supply of oxygen to blood.
Due to the decreased oxygen, the man can have headache, dizziness, nausea, breathlessness and fatigue.
