Immune cells in the blood increase after exercise: Two recent studies conducted by Finnish scientists concluded that just 10 minutes of exercise can increase the number of immune cells in the blood, which is essential in the fight against cancer. These studies involved 28 patients with newly diagnosed lymphoma and breast cancer. During the 10-minute cycling exercise, the number of cytotoxic T cells (which destroy cancer cells) and natural killer cells in the blood of lymphoma patients increased, along with the number of white blood cells, intermediate monocytes, and B cells.

Blood vessels dilate after exercise, which helps lower blood pressure: Exercise is a way to help blood vessels become younger without taking medicine or injections. Exercise-induced nitric oxide dilates blood vessels and promotes blood flow. Clinicians will consider prescribing "exercise" for patients with hypertension. Additionally, slight sweating during exercise helps to excrete sodium from the body.
