What is the appropriate amount of time to exercise every day
By Dr. Anthony Policastro
When we listen to news stories, we sometimes hear what we want to hear. A recent report in the Lancet was quoted on ABC World News with Diane Sawyer. The report said that people who exercise for 15 minutes per day can decrease their risk of death. They can increase their life expectancy by three years. The implication was that you really did not need to do that much exercise. However, there was more to the report than just that tidbit. The first has to do with the size of the group that was studied. They looked at 416,000 people in Taiwan. When you have that large a group, it means that some people did benefit from the exercise. It also means that others did not. The overall result was that the group who did more exercise had better results overall. It does not mean that each person in that group lived three years longer. The second issue is the way they collected the data. They asked people how much exercise they did the previous month. If I were to go up to an individual to ask them what their exercise routine was for the last month, they likely would not know. In this study, they asked the question every month for 8 years. Therefore, the reports are probably more accurate. However, they still only asked people to self report. They did not actually measure the exercise level which means that some people could have exaggerated. The third issue is related to those people who exercised for more than 15 minutes per day. The study found that each extra 15 minutes of exercise per day decreased the risk of death by an additional 4%. That means that 15 minutes cuts the risk by 14%. Thirty minutes cuts it by 18%. Forty-five minutes cuts it by 22%. One hour of exercise cuts it by 26%. Seventy-five minutes leads to a 30% decrease. Ninety minutes resulted in a 34% decrease. However, after 100 minutes per day, there were no further increases. The bottom line here is that 60 minutes per day takes you from the 14% related to 15 minutes of exercise to almost double that at 26%. That should keep those who currently exercise for an hour at a time from cutting back to only 15 minutes a day. What is the most important thing here is that even a small amount of exercise is better than no exercise. Those who say that they do not have the time to exercise really cannot use that as an excuse any longer. There is usually more to the story. This is no exception to that. It should be looked at as encouragement for more people to take up exercise. It should not be seen as encouragement to do less than we currently do.

Free prostate cancer screenings Bayhealth Medical Center will offer prostate cancer screenings free to those who qualify during Prostate Cancer Awareness Month in September. These screenings are part of Bayhealth's continuing efforts to educate the community and help people identify cancer in its earliest, most treatable stage.
Prostate cancer is the most frequently diagnosed cancer in men and the second leading cause of cancer deaths for men according to the American Cancer Society. Annual screenings are recommended if you're a man over the age of 50, or over the age of 40 with a family history of prostate cancer in a close relative diagnosed before age 65. African-American men are twice as likely to die from prostate cancer and should begin screenings at the age of 40. The Bayhealth Cancer Institute is providing prostate cancer screenings which consist of a prostate specific antigen (PSA) blood test, and a digital rectal exam (DRE). The screenings are free to those who qualify but pre-registration is required no later than one week before the screening. For any questions, and to register, call 430-5064 or 744-6752. In Milford, screenings will be held from 9 to 11 a.m. on Saturday, Sept. 17, at Bayhealth Cancer Center located at 21 W. Clarke Ave.
