9. Reduce Risk Of Certain Cancers
As well as helping to reduce our risk of developing coronary heart disease and type 2 diabetes, regular exercise can also help to reduce our risk of developing certain cancers. Cancer is an emotive subject and a complicated disease with many causes. But according to the NHS, remaining active throughout life can reduce our risk of developing colon cancer by up to 50% and breast cancer by up to 20%.
Cancer Research UK say that some breast cancers are linked to the level of hormones in the body, including oestrogen and insulin. It’s thought that oestrogen could make the cells that make up breast tissue divide more often than they should do which can lead to breast cancer. Exercise can help to reduce oestrogen levels. Insulin can also have the same effects on cell division, and can be reduced by exercise as we discovered above.
They also say that regular exercise helps to keep the bowels healthy by promoting regular bowel movements. This means that digested, unwanted food waste doesn’t stick around the digestive system as long, reducing the time that potential toxins can come into contact with the bowel and cause cancer.
Being active also reduces the level of inflammation in the body, which if left unchecked, is another potential precursor to bowel and other cancers.
