Running will not just help a person lose weight, improve cardiovascular health, and reduce depression. It also promotes inflammation and cardiac failure on the other hand. Studies suggest not to over-rate running to be beneficial all the time.
When running, a person would feel the heart beat pound faster and it usually feels good especially when the sweat go off through every pore. But for most people, it is very dangerous and can actually backfire. Long-term excessive sustained exercise can be linked to "coronary artery calcification, diastolic dysfunction, and large-artery wall stiffening", according to a study presented by NCBI. Such study still suggests that exercise is good for cardiovascular health and longevity but it is very necessary to identify at-risk individuals and be able to formulate physical fitness that matches their special conditions.
A person who runs on a regular basis can later experience damage to weight-bearing joints like knees and ankles. As much as the heart and lungs are believed to function to its maximum level when running regularly, heart attack risk is also high for runners. Other disadvantages that may happen because of too much running are breast sagging, and some systematic inflammation, which can lead to oxidative damages that may be carcinogenic.
A 58-year old man died of a heart attack while running, as featured in New York Times during the 2008 New York Marathon. Some who have high cholesterol and warning signs for coronary heart disease like nausea, angina, and epigastric discomfort are in danger of killing himself or herself while running.
The risk of fatal heart attack during a marathon or within 24 hours of running is only one in 50,000 according to a 1998 study. However, it has been almost two decades ago after such study was released. There are many changes in the environment, industry, and foods taken in. People who are in their mid-forties or older need to get a doctor's approval before getting into a marathon or regular running. You'll never know if you will be damaging not just your heart but your kidneys as well, as one study presented in CBC. Most of your systems are actually at risk.
