Walking Away From Colds

  It might seem difficult to believe, but walking in autumn and winter plays a major role in reducing colds. We all sit nicely inside with a cup of hot tea and a warm blanket. But believe me, it will not protect you from colds in the winter, since the first moment when your weak immune system comes into contact with a virus, common cold will not bypass. In fact, going outside and walking can help you avoid colds.


Recently, a group of scientists who worked on this subject received surprising results. It was a group of 50 women divided into 2 groups, one group was hiking 5 days a week for 45 minutes with moderate speed, and the other had no exercise. Those who walked, had 2 times less colds the following winter, compared to other-control group. The women who walked also increased the percentage of so-called natural killer-cells, which are actually cells of the immune system which attack bacteria and viruses. Also, people which go to the gym at least 2 times a week, have 5 days to less with colds than those who do not practice this activity.

  Contrary to traditional ideas of sitting at home, away from the cold air, walking at low temperatures strengthens immunity, improves the heart and makes you healthier. To this add the extra calories burned, and you have a winning combination. The body has a natural response to the lower temperature, and in order to keep the body warm, works with higher metabolic rate, hence burns more calories.

  The trick is in moderate activity. Those who exercise daily with a very strong effort, have a different goal. But others who simply want to protect their health, they will do just fine with walking 2-3 times a week for 30 to 60 minutes. Note that excessive activity that causes sweating a lot doesn't go well with the low temperatures outside. So walk moderate and often, and warm up afterwards with hot drinks or soup.
  Good things is life are simple - Walk away from colds!
