Here is another reason to exercise! It turns out that several studies have shown that it can help reduce risk of cancer. This particular study showed a reduction in skin cancer in mice.

 Exercise enhances a process called UVB-induced apoptosis, which means programmed cell death. This is a good thing: It kills sun-damaged cells.

 

"While UVB is triggering the development of tumors, exercise is counteracting the effect by stimulating the death of the developing cancer cells," said study leader Allan Conney of Rutgers University.

 

So not only does exercise help us lose weight and help our hearts to work better and strengthen our bodies, but it can help defeat cancer! Very cool!
