Experts have long debated the best time to exercise, but now, researchers have identified two sweet spot sweat intervals that could play a “crucial role” in cancer prevention.According to a revelatory new study, being active first thing in the morning or later in the evening may reduce the risk of bowel cancer by 11% — and they’ve even narrowed it down to two times on the clock.Researchers published their findings in the journal BMC Medicine and maintain that highlighting specific times when physical activity is “most beneficial” could lead to targeted cancer prevention strategies.Led by experts from Germany’s University of Regensburg, the study assessed 86,252 people aged 42 to 79 whose physical activity was tracked and measured using a wrist accelerometer.Researchers highlighted four activity patterns among this population: continuous activity throughout the day, activity late in the day, activity in the morning and evening, and activity at midday and at night.Over a five-year follow-up period, 529 cases of colorectal cancer, also called bowel cancer, were reported.Researchers determined that two daily peaks, at roughly 8 a.m.
and 6 p.m., “were associated with reduced colorectal cancer risk, beyond the benefits of overall physical activity.”According to the study, people active in both the early and late parts of the day had an 11% lower risk of colorectal cancer, compared with 6% for daylong activity and no change for those who exercised in the middle of the day and the evening.Data from those who were only active later in the day proved inconclusive.Professor Dr.
Michael Leitzmann, chair of the Department of Epidemiology and Preventive Medicine at Regensburg, was the lead investigator for the study.“Our study highlights that not only is physical activity important for reducing colorectal cancer risk, but the timing of peak activity throughout the day could play a crucial role,” he said.He and his team are hopeful their findings can help ...
