Too much exercise can be a bad thing

ISLAMABAD: One tries different workout methods to look fit but too much exercise can lead to damage too, says an expert. Whilst diet is almost always carefully planned out, or at least thought of, many fail to realise the impact training can have on the rest of their body.

Though brisk walking for 30-45 minutes five days a week has been shown to boost immunity, more strenuous activities may have a negative impact on the body, says fitness expert Erin McCann. “When the body is exposed to physical stressors such as exercise it responds in a similar way to how it does when exposed to mental stress the hormone cortisol is released.
“Cortisol stimulates energy production and improves muscle endurance which supports fight or flight reaction. Cortisol however also acts as an immunosuppresant and following even just a moderate workout, immune function can take up to 72 hours to fully recover. This leaves individuals open to viral or bacterial infections. Study suggests top three ways to support immune function: Incorporate adequate recovery time into your workout schedule. This will aid muscle recovery, reduce the risk of injury and improve immune health.
Increase consumption of immune supporting nutrients and antioxidants through food. Examples include Vitamin C containing foods, like berries and broccoli, as well as zinc rich foods like eggs and pumpkin seeds.
Supplement with immune boosting nutrients and herbs that are not commonly found in an every day diet. Examples of these unique immune supporting agents are astaxanthin, reishi mushroom, bee propolis and olive leaf. Astaxanthin is a carotenoid with potent antioxidant and anti-inflammatory actions, and is often used by athletes to support muscle recovery and immunity.
Another study suggests that weight-loss tamarind and anti-depressants are a deadly mix
Are you taking weight-loss supplements while on anti-depressants? Take caution because the popular weight-loss supplement garcinia cambogia famously known as Malabar tamarind could lead to toxicity in the body.
Previous studies have shown that garcinia cambogia may, in fact, increase the levels of serotonin a neurotransmitter. New research found that taking the supplement in combination with anti-depressants known as selective serotonin reuptake inhibitors (SSRIs), which also cause serotonin levels to rise could lead to serotonin toxicity.
“People who are taking SSRIs should not use garcinia cambogia at least until further research is done,” said D. Robert Hendrickson, a toxicologist at Oregon Health and Sciences University.
The hydroxycitric acid (HCA) compound in the fruit Malabar tamarind is touted as a fat-burning, metabolism-boosting, appetite-suppressing weight-loss product. “If I had a family member or a patient who was considering starting Garcinia and they were on an SSRI, I would recommend that they do not do it for now,” a Live Science report quoted Hendrickson as saying. The study appeared in the Journal of Medical Toxicology.
Whereas a study warns that diabetes may shrink brain by two years in a decade.
What has diabetes to do with your brain? Well, it may shrink your brain by two years every decade, an alarming research has indicated. It is the first such study linking diabetes to a change in the size of the brain.
“Our research found that patients having more severe diabetes had less brain tissue, suggesting brain atrophy,” said University of Pennsylvania’s Perleman School of Medicine’s Professor of radiology, Nick Bryan. They did not seem to have more vascular disease due to the direct effect of diabetes, Bryan added.
To find evidence, the researchers used magnetic resonance imaging (MRI) scan to find the link between type 2 diabetes and brain structure in 614 patients.
The findings showed that longer duration of diabetes was associated with brain volume loss, particularly in the gray matter. For every 10 years a patient has diabetes, their brain looks approximately two years older than that of a non-diabetic person in terms of grey matter volume.
However, they found no association of diabetes characteristics with small vessel ischemic disease in the brain, a Daily Mail report said. This opens up a new pathway to treat patients with diabetes, the study concluded.
