Healthy breathing draws oxygen through your nose and down to your lungs, giving your body the energy it needs. But as you sleep, phlegm can build up in the back of your throat, blocking the passage of oxygen from the nose to the lungs. You may compensate by breathing through the mouth, but a recent study shows that doing so is correlated to a significantly lower blood-oxygen level, which can lead to fatigue. Gargling every morning, whether with mouthwash or salt water, can help clear the throat’s phlegm, allowing more oxygen to reach the lungs which boosts your energy.
