How Exercise Might Keep Depression At Bay

By keeping yourself physically active you are making a huge favor to your health. Exercising keeps your mental health as well and it keeps you away from depression. In the studies done in the past which included more than a million male and female participants, there were statements that regular exercises revive our mind and body. In this way we become resistant to depressive mood.

Scientists have been long analyzing the matter how physical activity and mental health are related. We are all aware that physical exercises have a good influence on our bodies, but how it affects our emotional state is less known.

It was proven that walking is the best physical activity when it comes to improving your mood and relieving the symptoms of depression.

But many of these studies often had other scientific deficiencies. In 2013, there was a review of studies on this topic was stated that, based on the evidence then available, it was impossible to conclude whether exercising helps with depression. Similar reviews have also lacked strong evidence that exercise can prevent depression.

However, a group of global public-health researchers claim that newer studies and a thorough review of the statistical data might give an answer to this interesting theme. They started with gathering all of the latest and best-designed studies about the connection between depression and exercise.

The most innovative study was published last month in Preventive Medicine. The focus was on whether exercise can have that much positive influence on keeping your mental health in a good state. The scientists took into consideration the fact that many past studies involved people who reported how much they had exercised. But, we know how people can be notoriously unreliable in our memories of past workouts. So, the researchers decided use only past studies that had objectively measured on whether and how much someone exercises aerobic fitness. They also determined the participants’ mental health by standard testing at the start and finish of the studies. The follow-up time was determined to at least a year and longer. They gathered information on more than 1.140.000 adult men and women.

Among these participants, it turned out that fitness and mental health are closely connected. The researches divided the group into thirds, based on how aerobically fit they were. Those men and women with the lowest fitness were about 75% more prone to depression than the people who dedicated more time to fitness.

In June, there were published 25 studies in the Journal of Psychiatric Research. In those studies, people with clinically diagnosed depression, started some type of exercise program. Each study had to involve a control group that did not exercise and be otherwise methodologically sophisticated. The results showed that exercise, especially if it is moderately demanding, such as brisk walking or jogging, and supervised, so that people complete the entire program, has a considerable effect against depression. People’s mental health was greatly improved if they were engaged in some physical activity.

The final review was dedicated on why is that so. In Neuroscience and Biobehavioral Reviews, published in February, there was an explanation what happens within our bodies during and after exercising. The researchers took into consideration 20 past studies in which studies had obtained blood samples from people with big depression, before exercising and after. The samples in general signified that exercise notably reduced inflammation and increased levels of a number of different hormones and other biochemicals that are considered to contribute the health of the brain.

The Brazilian exercise scientist, Felipe Baretto Scuch and Brendon Stubbs, a professor at King’s College in London, were the principal authors of all these reviews. They claim that these reviews signify a strong evidence when it comes to connecting physical and mental health.

Dr. Schuch said that further testing is still needed to establish the ideal amounts and types of exercise that might help to prevent and treat this mental condition. He strongly advises walking, running or riding a bike to relax yourself. At the end, he and his colleagues said that it is beyond important to stay practice some physical activity if you want to take care of your mental state.
