5 scientifically proven health benefits of exercising regularly
The first thing that comes to mind when thinking of health benefits of exercising regularly is: weight loss. But, scientists continue to find out more health related advantages in quitting a sedentary life, and become more active. Here are 5 scientifically proven health benefits of exercising regularly, which goes way beyond weight loss.
1) Mental Health
The first on the list has to be mental health, because if our brain is not functioning well. Our entire body will also be out of balance. So, it’s important to invest in brain health and this can be done with moderate exercise, according to scientists.
A study assessed the impact on depression and functioning of a moderate intensity exercise program for 12 weeks, as an adjuvant to pharmacotherapy, in treatment-resistant Major Depressive Disorder patients (MDD). It was found that the exercise group showed improvement of all depression and functioning parameters. Scientists observed that this home-based exercise program of 30–45 min/day walks, 5 days/week, improved depression and functioning parameters in treatment-resistant MDD patients, and contributed to remission of 26% of these patients.
Exercising has also been proven to improve cardiorespiratory fitness in people with depression. This is good news, because some studies suggest that major depressive disorder, and even subthreshold depressive symptoms that do not meet the criteria for a diagnosis of major depressive disorder are risk factors for the development of coronary heart disease events in healthy patients. It is important to note that cardiorespiratory fitness is an independent predictor of cardiovascular disease and all-cause mortality.
Another health benefit of exercising regularly is that physical activity helps with drug addiction recovery, and the reason for that is because regular exercising regulates dopamine release, which if unbalanced has been linked to depression and anxiety.
2) Postoperative recovery
A recent study on whether a pre- operative medically supervised exercise program, would affect the outcome of an abdominal aortic aneurysm(AAA), found yet another health benefit of exercising regularly, because it was found that in the exercise group there were less complications and the duration of hospital stay was significantly shorter. It was concluded that a period of preoperative supervised exercise training reduces postoperative cardiac, respiratory, renal complications, and length of hospital stay in patients undergoing elective AAA repair.
3) Heart health
A cohort analysis among 4207 US men and women of a mean age of 73 years who were free of cardio vascular disease, were followed from 1989 to 1999. Researchers observed that greater Physical Activity was inversely associated with coronary heart disease, stroke (especially ischemic stroke), and total cardio vascular disease, even in those ≥75 years.
4) Liver diseases improvement
Perhaps one of the best health benefits of exercising regularly is that it helps your liver to detox. A study on 30 men with clinically defined Nonalcoholic fatty liver disease (NAFLD), found that resistance training and aerobic training are equally effective in reducing hepatic fat content and liver enzyme levels among patients with NAFLD. However, aerobic exercise specifically improves NAFLD independent of any change in body weight. It is important to note that Nonalcoholic fatty liver disease is a risk factor for diabetes and cardiovascular disease that could progress to nonalcoholic steatohepatitis, cirrhosis, and liver failure.
An analysis was conducted to determine whether exercise training without dietary restriction in obese, middle-age men influences the pathophysiology of abnormal liver function. In this study, 108 subjects who completed a 12-wk exercise training program without any dietary restriction were analyzed; these results were compared with those of 104 subjects who completed a 12-wk dietary restriction program.
It was observed subjects with abnormal liver function and suspicious liver fibrosis, exercise training was effective in reducing the serum levels of inflammation and oxidative stress markers: ferritin and thiobarbituric acid reactive substances. Therefore it was concluded that Exercise training benefits the management of obesity-related liver diseases independent of detectable. weight reduction.
5) Toxins detox
We live in a polluted world, so its important to find ways to detox. Pollutants like the arsenic, cadmium, lead, and mercury have no known beneficial effect in humans, because , all four elements are confirmed or probable carcinogens, and they exhibit wide-ranging toxic effects on many bodily systems, including the nervous, endocrine, renal, musculoskeletal, immunological, and cardiovascular systems. Sweating through exercise, is one of the best ways to detox from these environmental pollutants.
As it can be seen, there are many health benefits of exercising regularly, and its not only related to weight loss, which is a by – product of frequent physical activity.
