How Does Exercise Impact Your Immune System?

How does vigorous exercise impact your immune system? In the past, it was believed that intense exercise will make you more susceptible to illness. But the results of a recent study seem to suggest the opposite. Published in the Frontiers in Immunology journal recently, this study hints that intense exercise in fact does not blunt the immune system’s effectiveness. Rather, it may improve immune system performance, and in any case does not appear to make your immune system less effective. This meta-analysis, which is a study of the results of numerous other studies, cannot prove this conjecture, but it does highlight strong evidence that appears to confirm the hypothesis. The authors take a fresh look at the measurable immune system [Read more …]

Extend your lifespan more than a decade with these healthy habits

This week the journal Circulation published a new study that has found five healthy habits that can extend lifepsan up to 12 years for men, and 14 years for women, if these habits are adopted by age 50. What are these healthy habits? “Adherence to 5 low-risk lifestyle-related factors (never smoking, a healthy weight, regular physical activity, a healthy diet, and moderate alcohol consumption) could prolong life expectancy at age 50 years by 14.0 and 12.2 years for female and male US adults compared with individuals who adopted zero low-risk lifestyle factors.” The study reviewed the findings from two studies that occurred over a 34 year time frame, and included over 120,000 subjects. Let’s take a look at these healthy [Read more …]

High Blood Pressure – What You Need to Know

High Blood Pressure, or Hypertension, is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. Blood pressure is described by two different measurements – the systolic and diastolic pressures – which are the maximum and minimum pressures. Systolic is how much pressure your blood is exerting against your artery walls when the heart beats. Diastolic indicates how much pressure your blood is exerting against your artery walls while the heart is resting between beats. The units of measurement are typically millimeters of mercury, abbreviated as mmHg or mm Hg. High Blood Pressure is sometimes called the “silent killer” – because there can initially be no obvious symptoms. But when left untreated, the ongoing damage [Read more …]

Sitting – The New Smoking?

Dr. James Levine, the director of the Mayo Clinic at Arizona State University says that “Sitting is the new smoking“. Smoking, once a popular activity, was not recognized as the extreme health danger it was, until many years later. And now sitting may be in the same category. At first, this sounds ridiculous. But there’s a bevy of studies backing this statement up – and a possible logical explanation for why sitting for long duration is unhealthy. First, we’ll spoil some of the surprise – it’s not sitting in particular, but extreme sedentary habits that seem to be the risk factor. Secondly, it appears that being sedentary all day, then hitting the gym is not an effective solution. The extended [Read more …]

Everybody needs sleep. But did you know that a lack of proper sleep can increase the risk of diabetes and other risks? Having good sleep habits is also known as sleep hygiene.

That’s obvious, but what is less obvious is the impact on your hormonal systems that can also occur. Increased Risk of Type 2 Diabetes If you are chronically missing too much sleep, you are raising your risk for Type 2 Diabetes. How does this happen? Through research, it has been shown that not getting enough sleep (for example only 4 hours a night or [Read more …]
