In his article on Times, David Nieman, Ph.D., talks about how you can slash your risk of developing diseases during this season. He conducted numerous studies on the best ways to turbo-charge the body’s ability to ward off illness.

Of these, he learned that being physically active was one of the best ways to cut your risk of falling victim to cold or flu. Dr. Nieman highlights, “If you look at all the lifestyle factors that decrease the number of days you suffer from common cold, being a physically active and fit person is the most important.”

How long should you exercise for an improved immunity?

The stronger your immunity is, the more resistant you are to developing infections. Subsequently, you are able to safeguard yourself against common cold and flu symptoms and escape the winter season unscathed.

The significance of physical activity in this regard is undeniable. So, if you are thinking about escaping a day at the gym, think again. You need to be physically active, however, that does not mean that you over-work yourself.

Dr. Nieman explains that there is a sweet spot, which makes effective. To this end, he suggests 30-60 minutes of light aerobic exercise every day. This will help to increase the circulation of your white blood cells and other flu-fighting cells in the body.

There’s one concern though, you need to keep active throughout the day to keep your immune system active. After three hours of your light aerobic exercise, the blood circulation of white blood cells goes back to its original levels that were before the workout.

Therefore, you will need to move around more to keep the white blood cells in healthy circulation. This means that you may have to walk instead of taking a ride in a cab.

Don’t tune into the lazy mode no matter how cold the weather gets. After all, you have got to develop strong defenses against disease-causing agents of the cold.
