2. Being Overweight -if you are heavy than your lungs are working over time.

3. Not Enough Oxygen in Your Blood- you may suffer from a blood imbalance and may not be able to support your body functions correctly with the amount of oxygen in your blood.
   This health problem may also be the result of inadequate oxygen balances in your blood.
