The atmospheric pressure is lower at high altitude than at sea level. If someone gets to a place of higher altitude, his breathing rate increases. This is probably due to the fact that
the heartbeat rate of a person is faster at higher altitude.
the percentage of oxygen in air drops at higher altitude.
the metabolic rate of a person is faster at higher altitude.
the amount of oxygen inhaled in each breath of a person is lesser at higher altitude.

People may feel dizzy if they sit down immediately after vigorous exercise because

the relaxation of skeletal muscles leads to a decrease in the blood flow to the brain.
the accumulation of carbon dioxide in the blood affects the functioning of brain cells.
