Some research suggests that the physical benefits of hiking extend far beyond cardiovascular health, and may even go as far as to help cancer patients recover. In a study published in the International Journal of Sports Medicine researchers measured oxidation stress (thought to play a role in the onset, progression and recurrence of cancer) rates of women with breast cancer and men with prostate cancer before and after hiking. The study found that long distance hiking trips may improve the antioxidant capacity, which helps fight off disease, in the blood of oncological patients. Another study showed that breast cancer survivors who exercised regularly — many in the form of hiking — believed that physical activity complemented their recovery from cancer treatment.
