About Physiological changes from exercise
Physiological changes occur in the brain and tissues of your body. How your body internally changes and rewires itself from exercise. Exercise will increase blood flow to the brain and tissues of the body which will deliver more oxygen to those tissues. When blood flow is increased to the brain, your neurotransmitters; such as endorphins or serotonin help improve mood, cognition and memory. Oxygen delivers nutrients to the tissues as well and allows them to discard any wasteful products in the blood. Exercise also reduces your muscle tension as well as strengthening the muscles and increasing your cardiorespiratory fitness. Exercise gives you a sense of control over your actions. It can boost your self-esteem and self-efficacy. Exercising regularly can help you feel better about your self-image which will correlate to a more positive mindset. Exercise improves your overall well-being and can be an outlet to meet new people and socialize. Finding what activities you enjoy can greatly increase your intrinsic motivation and make it more enjoyable to stay healthy.
