And the Number 1 cause of stress is ... money

If you cannot sleep at night, chances are it is because of cash woes.

Money is many Americans' top worry, ranking higher than health, family and work, according to BlackRock's annual Global Investor Pulse survey.

But there can be some relief, BlackRock found. Those who are saving for a retirement feel better overall than those without a retirement savings plan, the study said.

".....what we found is that there are immediate benefits for those who start early," he added. "Much as physical exercise has both short- and long-term benefits, focusing on retirement planning helps alleviate stress and improves your overall well-being today."

Researchers discover how sleep helps the body fight germs

It looks like your mother was right: when you've got a cold, sleep may be the best medicine.

German researchers have discovered one way sleep improves the body's ability to fight off a cold. Sleep, it seems, strengthens the potency of certain immune cells by improving their chances of attaching to-and eventually destroying-cells infected with viruses.

The researchers focused their attention on T cells, which battle infections. When T cells spot a virally infected cell, they activate a sticky protein known as an integrin that allows them to adhere to that cell. The researchers were able to prove that lack of sleep, as well as sustained periods of stress, lead to higher levels of hormones that appear to block the master switch that activates the sticky proteins.

If you want to have your immune system tuned up to fight off invaders, "get the needed amount of sleep every night and avoid chronic stress," said study leader Stoyan Dimitrov, a researcher at the University of Tubingen, Germany.


When you sleep, repair hormones will be released during the deep sleep period to repair damaged cells in your body. If you do not have 'good' sleep, you will have more and more damaged cells in your body as they are not repaired.

Is tea good for you? Here’s what the experts say

What’s the most widely consumed beverage in the world, after water? The answer is tea, which is consumed by about 3 billion people worldwide, reports the Food and Agriculture Organization (FAO).

This hugely popular beverage has been around for centuries and plays a key role in many Asian cultures.

The main health-promoting substances in tea, produced from the Camellia sinensis plant, are known as polyphenols, which are antioxidants that help protect cells from damage. All types of tea have polyphenols, particularly catechins and epicatechins, but the amount they contain varies depending on the way they are processed.

Green tea, which is made with steamed tea leaves and is minimally processed, has higher amounts of polyphenols, including high concentrations of the catechin EGCG. Black tea, which is oxidised and then dried, has lower amounts of polyphenols. Instant and bottled teas have lower levels of polyphenols.
