Have you ever wondered about one magic activity that could reduce the brain fog that comes with age, prevent depression, stress, lowers blood pressure and lowers the odds of having heart problems, or simply makes you feel and look beautiful? Well there is definitely one such activity that covers it all: Exercise.
Exercise is the physical activity that is planned, structured and repetitive intended to improve or maintain physical health. Generally in exercise you work up to sweat, with increased breathing rate and heart rate.
WHO recommends adults aged 18-64 should do at least 150 minutes of moderate-intensity aerobic physical activity throughout the week or do at least 75 minutes of vigorous-intensity aerobic physical activity throughout the week or an equivalent combination of moderate- and vigorous-intensity activity. Muscle-strengthening activities should be done involving major muscle groups on 2 or more days a week. CDC and NHS recommends the same amount of exercise for people 65 and above if they are generally fit and have no limiting health conditions. In case if we are restrained by our health, we can at least try to be as physically active as our abilities or the health conditions allow.
So, what really happens to our body when we Exercise?
Recent research has suggested that the Exercise we do to improve our body also helps our brain.When we do high intensity Exercise our heart rate increases, supplying more blood flow to the brain. The increased heart rate also increases our breathing, making us breathe harder and faster. As a result more oxygen is supplied in our blood stream, more oxygen reaches our brain. This leads to neurogenesis, which is the production of neurons. Research has indicated that physical Exercise increases neurogenesis in the hippocampus, brain area important for learning and memory.
Additionally, exercise also modulates the secretion of major neurotransmitters dopamine and serotonin which are linked with treating depression. Indirectly, Exercise improves mood and sleep, and reduces stress and anxiety. Trouble in these aspects of our life frequently causes or contributes to cognitive impairment.
