Thoughts that can trigger anger include personal assessments, assumptions, evaluations, or interpretations of situations that makes people think that someone else is attempting (consciously or not) to hurt them.
What increases our body's oxygen? Aerobic exercise is any exercise that increases the level of oxygen in the body. This exercise, whether it be breathing more, walking, jogging, cycling, dancing, or swimming, conditions the heart and lungs to work more efficiently.
Depending on the type of exercise you are practicing, you can also increase the mass of your muscles by lifting weights. Note that you can alternate between aerobic and non aerobic exercise. Aerobic exercise requires a ventilator in front of you, at its lower speed, so that more oxygen is inhaled.
