Morning exercises may reduce prostate, breast cancer risks and help weight loss, improve memory

A new study published in the International Journal of Cancer suggests that exercise performed at different times of the day may affect circadian rhythms. Such circadian disruptions can be linked to breast and prostate cancer. The study explains that circadian disruption occurs when the endogenous or internal circadian rhythms are not in sync with environmental and social stimuli such as light exposure, work hours, diet and physical activity patterns.

Exposure to artificial light from bulbs or blue light from devices at night, night shifts and irregular meal intake timings can interfere with the normal nocturnal hormone production, especially of hormones like melatonin and cortisol. Imbalances in these hormones can have numerous biological consequences and recent studies have linked such disruptions with increased cancer risks.
