Being outdoors may reduce the risk of heart disease, according to a study.
The International Journal of Epidemiology published the findings of scientists from the Johns Hopkins School of Medicine, according to which people who often walk in the fresh air have a good chance of keeping their heart healthy. According to experts, being outdoors helps prevent heart disease by getting enough vitamin D from sunlight. They attribute the effect of this vitamin to reducing inflammation, a factor in cardiovascular disease.
“Inflammation may be a normal response of the immune system, but if it is too strong, it can increase the risk of developing chronic diseases, including heart disease. People with higher levels of vitamin D are less likely to experience severe inflammation,” the researchers state.
In favor of their opinion, data from an analysis of 294,970 people, participants in the British Biobank, speak. Researchers have become convinced that there is a link between vitamin D and inflammation, which is considered the driving force behind heart disease. In particular, a decrease in vitamin D levels has been found to correlate with an increase in C-reactive protein, a marker of inflammation. In turn, an increase in vitamin D in the body is associated with lower levels of inflammation.
What is the easiest way to get vitamin D?One of the most affordable ways is to walk in the fresh air. The human body is able to organically synthesize the vitamin just by being outdoors. In sunny weather, it is enough to stay outside for up to 20 minutes.
