Being a night owl is known to raise the risk of a variety of diseases.

People who prefer to be more active during the evening, and who go to bed later and get up later, have higher rates of metabolic dysfunction, cardiovascular disease, type 2 diabetes, psychiatric symptoms, mood disorders and winter depression.

But no scientist has ever examined whether these problems increase the risk of death. So two researchers, one from the US and another from the UK, joined forces to find out.

For the study, Kristen Knutson, associate professor of neurology at Northwestern University, Chicago, and Malcolm von Schantz, professor of […]

If you’ve had your blood cholesterol tested recently, you ought to know that many researchers now agree with what I’ve believed for years – it’s a dubious guide to your health status.

But it’s a persistent medical myth – the notion that your cholesterol levels determine your future well-being and your heart health.

Meanwhile, studies now show there’s a different blood analysis that actually does offer valuable information about your health future. Keep reading for this exciting news. . .

First I want to point out that when you look at studies of how accurately cholesterol test results correlate with things like life […]

A recent investigation into the ways in which exercise affects longevity shows that the amount of exercise you do and its intensity may not be the most important factor in helping you live longer.

Instead, in a finding that surprises me, the researchers found that your attitude toward exercise has an outsized effect on your chances of extending your life expectancy.

Here’s a full report on this weird result…

In a Stanford study, people who believed they were more active than other people lived longer than those who believed they didn’t exercise much – even when the exercise levels were, in both groups, […]

How can two people both born in the same year appear so different?

One looks half their age while the other displays many of the signs of aging. Then again, outward appearances may suggest they’re the same age, but they may have very different health-related futures and life expectancy.

In short, their chronological age may be the same but their biological ages may be quite different.

Finding a way to measure a person’s “real” age (as opposed to what the calendar says) could be far more valuable in identifying and predicting risk factors that influence health and length of life.

Now researchers from China have come […]

A vast range of herbal teas offers all kinds of health benefits. Heaven knows, they get a lot of publicity, but I still bet you don’t know about a tea with strong anti-aging abilities that’s grown only in a certain region in South Africa. It may even reduce wrinkles.

Its history is rooted in the small Cederberg mountainous region near the Cape of Good Hope, where Bushmen have harvested the leaves for centuries. They use it to treat a wide range of health problems, from skin to heart to bone health.

In fact, there’s almost no part of the body that doesn’t benefit from […]
