Active in midlife, healthy in old age

Researchers from the Harvard School of Public Health have found new evidence that women who are physically active at midlife have a better chance of being healthy in old age.

Data from the Nurses’ Health Study showed that women with the highest level of activity at middle age were nearly twice as likely to reach their seventies without experiencing any major chronic diseases or physical, cognitive or mental impairment. Results also showed that independent of other physical activity, women who walked at a fast pace achieved better health outcomes than those who walked at an easy pace.

Jean Hailes Research Director Prof Helena Teede said she was not surprised by the findings. “The benefits of being physically active at any age cannot be underestimated. It is especially important for women at midlife to stay active in order to reduce their risk of chronic diseases such as diabetes, heart disease and osteoporosis later in life.”

Herbal remedies may interact with heart medication

 A review in the Journal of the American College of Cardiology has found many patients are using herbal remedies or high-dose vitamin supplements without their doctors’ knowledge. These substances not only have a direct effect on the body, they can also interact with other medications. In heart disease patients, the interactions can have life-threatening results such as bleeding or increased risk of cardiac arrhythmias.

Jean Hailes naturopath Sandra Villella warns women to take care when using complementary medicine. “This research supports what herbalists already know about these herbs and their interactions. Unfortunately, patients are not always aware of these interactions and may self prescribe without disclosing this information to their doctor. The best place to obtain complementary therapy is from a qualified naturopath or herbalist and it’s essential that you let all your healthcare providers know which medicines (traditional and complementary) you are taking.”

Exercise reduces patient anxiety

Exercise is known to reduce depression but now an American review suggests it can also reduce anxiety in chronically ill patients. University of Georgia researchers analysed the results of 40 randomised control trials that included 2,914 patients with a variety of chronic medical conditions.

In 90 per cent of the studies, patients who exercised regularly experienced less worry, apprehension and nervousness compared to patients who did not exercise. The average reduction in anxiety was 20 per cent.

Jean Hailes psychologist Dr Mandy Deeks agrees that regular exercise can have a positive impact on mental health and wellbeing. “The physical effects of activity include slowed breathing and heart rate and the production of feel-good hormones (endorphins) which can act as natural pain relievers. Physical activity also makes us feel like we can cope better with everything life tends to throw at us. It is just as beneficial for the mind as it is for the body and we often forget this.”
