Stepping up exercise can the cold virus beat help

A Jogger passes two women on the National Mall in the vicinity of the Capitol NAP. regular exercise can reduce the chance of a cold.

There is always someone pass, a cold virus - whether it is covered in germs a stranger who sneezes in the elevator or a sick colleague who gives of a pen.But not everyone who exposed to virus gets a cold continues to the get sick.

"" One household think if a person gets sick,"says Ron Turner, a cold researchers at the University of Virginia.""Only about 30 percent of contacts in a household is actually develop infection."

So, how people can reduce your chances of landing in that 30 percent? researchers say there is cold combat strategy that could take advantage of many of us: intensification of daily exercise.

More exercise less disease?

The latest study, benefit from daily exercise to find journal was of sports medicine published this month in the British. Researchers recruited approximately 1,000 volunteers between ages 18 to 85 to a daily log of symptoms during cold and flu season to complete

"Everything from runny nose, sore throat, cough, fever, headaches," says researcher David Nieman Appalachian State University.

Dr. David Nieman, a more than 58 marathons and Super marathon runners, and an exercise Immunology at Appalachian State University studied endurance athletes immune system for decades. He found that the likelihood of Marathoners almost six times as high is sick after running of their race as people, which are suitable.

After about 90 minutes intensive effort, Nieman's tests on athletes show, to emphasize up, muscle breaks, hormones and inflammation go kicks cm "there is a window of a half-day or day where viruses to higher interest rate can increase because defenses are down," he says.

Marathoners are not alone in this: the key, he says any high intensity exercise is relentless."It is also also considered difficult to drive for three hours, three days in a row and then have high infection rates.""" People manual work have done for centuries, and this is what the body, used,"says Nieman.""It is only a recent phenomenon we go all out started."

Is there hope for endurance athletes race to beat colds?Nieman and colleagues get to develop funds from the U.S. Army, immune-boosting supplements for soldiers engagiert.Er is a phytochemischen in heavy, long fighting most of Quercetin, optimistic and antioxidant found in a number of fruit and vegetables.In a study 2009 Nieman cyclists were Quercetin 1000 mg per day (plus a few other additions) for two weeks before the race.Significantly fewer diseases had those athletes after the race than those on a placebo.

At the end of the three month study, the researchers found that the more participants exercised less reported sick.Those who experienced five days a week for 20 minutes or more exercised set 40 percent of fewer days of disease compared to those in less than a day a week of activity.

"It takes getting out most days of the week to see a real advantage," says Nieman.

Another study pursued Research Center in Seattle at the Fred Hutchinson Cancer, what happens when older, seated women start the week, and it found walking five days similar benefits.

Researchers how exercise may help prevent colds, but Nieman theorized are unsure that aerobic helps activity a number of important immune cells to recruit normally "in different parts of the body such as the spleen, lymph nodes, bone marrow camping,".

"" With practice, these cells come and start through the body at a higher rate, reproduce"Nieman says.""Are like the Marine Corps or special forces, get out there and poke holes in cells that may have virus in you."

"Researchers are not all convinced by Nieman's study.""Not that I would want someone from exercising hold," says Turner, of the University of Virginia.Aber he says it can play other reasons that some of us more vulnerable to sind.Gene for the common cold, for example, an important role.

Stress and sleep play a role

Studies show a few other factors prominently in cold virus vulnerability can pay.

Part of the story seems found that when people sleep poorly, you are much more common to catch a cold to schlafen.Eine comprehensive study of Carnegie Mellon University researchers.

"People who slept less than 7 hours 2.9 times more likely than people sick to 8 or more sleep", says Sheldon Cohen, a Professor of Psychology at Carnegie Mellon.

The risk of getting the cold also seems to emphasize bound werden.Keiner we can liberate us from all life little stressors, but research suggests the length stress wear us down.

"Chronic, ongoing chronic problems, as for example in a bad marriage, after a lousy job with greater risk linked," says Cohen.

But if exercise, less stress and more sleep can cut your risk – even a bit - you might be three more advantages of striving for a healthy lifestyle.
