Get Fresh Air

• When it comes to providing oxygen for your cells, there is no simpler method than opening the doors and windows and letting the fresh air in. Fresh outside air is more oxygen-rich than the air that circulates inside of buildings. Inside air becomes polluted with waste every time you breathe out, making it less and less oxygen-filled as time passes. Replacing the old indoor air with fresh air regularly will provide you with the oxygen your cells need for optimum health.
  
  Once you let the fresh air in, breathe deeply to pull it into the body. Proper deep breathing techniques involve using the entire expanse of the lungs, chest and abdomen. Each time you breathe in, fill your lungs completely. Your abdomen should rise as it fills with air. Then expel the air completely. Practicing this deep breathing technique for a few minutes each day can increase the oxygen levels in your blood and cells.
  
  

Exercise

• When it comes to raising oxygen levels, exercise plays an important role. Over time, regular exercise will increase the heart and lung's capacities, allowing for deeper breathing, which provides a greater intake of oxygen.
  
  

Diet

• A variety of foods can help increase oxygen levels in the blood. Eating regular, small meals, every two to three hours will keep the body properly fueled at all times and will prevent overeating, which can lead to oxygen deficiency. Meals should be full of nutrient-rich foods, such as fresh fruits and vegetables, and junk food and foods that are high in fat should be avoided. One of the best diets for raising blood oxygen levels is a low fat vegetarian diet with plenty of anitoxidants. Antioxidants are found in many of the fresh fruits and vegetables you will be eating, as well as red wine and dark chocolate. An extra boost of oxygen can be obtained by drinking oxygen-infused bottled water.
