Women Exercising as Teens Live Longer, Die Less from Cancer

If you’re a woman and getting at least 30 minutes a day of activity, that means a lower risk of colorectal cancer. Now a study published today suggests that women who exercised as teens for even an hour a week have a lower risk of dying from cancer in middle age and older compared to teens who weren’t active at all.Teenager Skater Girl Legs On A Skate Board

These women are also more likely to live longer overall, the study suggests, whether they exercised as adults or not.

The study included almost 75,000 Chinese women who were part of the  Shanghai Women’s Health Study. The women were 40 to 70 years old and they had answered questions about their lifestyle habits currently and decades earlier.

After an average of 13 years, the researchers looked how many of the women had died overall, and whether the cause of death was from cancer or cardiovascular disease.

Review: plenty of health reasons to get those young kids active

If being active is good for you — and you know it is — how important is it for young kids? Very, suggests a new review of the research out of the United Kingdom. The review points to how running about and playing sports as children links to numerous health benefits, many of which relate to lowering cancer risk decades later as adults.

For the review, researchers at the British Heart Foundation for Public Health England, part of the UK’s Department of Health, looked at how activity improves 5- to 11-year-olds mental, physical and long-term behaviors.

After finding then rating the studies, the review found strong evidence that activity helps kids’ cardiometabolic health, which puts them at lower risk to develop type 2 diabetes, obesity and other issues related to poor metabolic health. These studies generally focused on how physical activity linked to risk factors for chronic diseases, such as insulin levels and markers of inflammation. Many of these risk factors for heart disease and type 2 diabetes are also shared factors for increased cancer risk.

Here’s the PDF of the evidence review, and below is the summary of what they found.

Keep that Fitbit On: Exercise Helps Prevent Cancer

If you’ve seen the recent headlines warning that physical activity won’t help you lose weight, you may be wondering if your evening walk or daily workout is worth the time.

The answer is a resounding YES – do take that evening walk, keep your pedometer on and get your exercise in whether you want to lose weight or not.

In the last few weeks, there’s been one article after another with experts arguing about what’s most important for weight loss – diet or exercise. But getting lost in all this discussion is the overwhelming evidence that physical activity provides many health benefits independent of weight loss, including lowering risk for at least three cancers – endometrial, colorectal and postmenopausal breast.being-physically-active-decreases-risk-of-these-cancers

There’s no argument that getting to and staying a healthy weight is also important for cancer. But this debate misses the mark when it comes to shaping your health. It is true that you “can’t outrun a bad diet,” as the author of a Washington Post article “Take off that Fitbit” says. It’s also true that for better health you need to do more than just cut calories.

For example, in that Post article, the author cites a study showing that diet only led to more weight loss than a diet and exercise group. What he didn’t point out is that while the diet only group lost slightly more weight, they also lost more muscle and bone mass than the diet and exercise group. This is especially critical because the study’s participants were 65 and older. Exercise helps you keep your muscle and strong bones at any age.

Apps, tracking devices and pedometers have also been singled out as not being the answer to weight loss. But losing weight takes a lot of work – it is hard to eat less – and you need all the support you can get to succeed. So while these devices aren’t the answer, studies do show that tracking your food and exercise is one key component to successful weight loss. You can also use a notebook, calendar or checklist, what matters is keeping track of your progress.
