Physical activity lowers the risk of cancer

Regular exercise has many positive health effects, although depending on the time of day the effects may differ. A recent study showed that morning exercise may have the most benefit in reducing cancer risk.

Researchers from the University of Medicine of Vienna (MedUni Vienna) and Spanish colleagues from the Barcelona Institute for Global Health (ISGlobal) tried to find out the effect of physical activities at different times of the day on risk cancer. Depending on their results, there may be significant differences here. The results of the study were published in the “International Journal of Cancer”.

Melatonin and cancer risk

“The hormone melatonin is mainly produced by the human body at night and has been associated in some studies with a lower risk of cancer,” the researchers explain. It is also known that physical activity in the afternoon or evening can lower the rate of melatonin.

In 2795 participants in the population-based multi-case-control study (MCC-Spain), the research team therefore examined “whether sports activities in the morning could further reduce the risk of prostate and breast cancer. than sports activities that take place at other times of the day, “according to the Communication from MedUni Vienna.

Women especially benefit from morning exercise

It has become clear that “the protective effect of exercise on the risk of prostate and breast cancer is probably strongest when physical activity takes place in the morning from 8 to 10 am.” This was especially true for the risk of breast cancer in women. in men, the risk of prostate cancer was reduced to a similar extent even with regular evening exercise (7 pm-11pm).

In addition, the chronotype of participants, i.e. preferences for sleep and activity at a certain time, is also relevant for the effect of physical activity. Morning exercise (8-10 hours) seemed especially good for participants who normally prefer to be active in the evening – the so-called owls, the scientists report.

150 minutes of exercise per week

“The timing of physical activity can obviously affect the rate of sex hormones and melatonin, as well as nutrient metabolism,” says the research team. Even with the new findings, it is not yet possible to say exactly what time of day it is best to be physically active in order to optimally reduce the risk of cancer. However, the general rule of thumb is that you can significantly reduce your risk of cancer by simply incorporating at least 150 minutes of moderate physical activity per week into your daily life.
