Water in Winter…How important is it?  In spite of the sometimes frigid weather, walking during the winter does have some advantages.  The cold keeps your body temperature from rising and your body from sweating to compensate.  Does this in turn mean that can put your water bottle away with your summer walking equipment and don’t need to drink as much water?    Not quite.  While the loss of moisture through perspiration decreases, the rate of moisture lost through respiration/ breathing actually increases.

You lose moisture as you breathe.  Moisture from you lungs is absorbed by air during the breathing process.  As the air is exhaled the moisture present  leaves your body for the great outdoors .  Since cold air tends to be dryer than warm air, the moisture loss is significantly higher in winter than in summer. When engaged in normal everyday activity an individual will lose between one and two quarts of water a day through the simple act of breathing.  When engaged in moderate to strenuous physical activity the rate jumps to ½ to 1 ½ quarts per hour.   Another fact that enters into consideration is that the body can only absorbed about a quart of water an hour.  So with a simple bit of math you can readily see that the body can quickly deplete its’ water supply if proper precautions are not taken.  There is the potential for dehydration during exercise walking in the winter months and those precautions should be taken seriously.   (Seasonal celebrations also put some added stress and strain on our body’s water supply).

As is the case in summer, dehydration in winter can have some serious consequences.  Dehydration can accelerate hypothermia, frostbite and fatigue.  So you’ll want to consider these walking health and safety issues.

So what procedures should we follow to insure that we stay hydrated and healthy?  Basically it’s the same ones you should be following during the summer months. 

• Drink a bit of water an hour or so before you head out on your walking excursion.  Probably about ½ to 1 quart, depending on your walking style and pace.

• Periodically sip a bit of water throughout you walk.  Don’t rely on your thirst level to tell you when to drink.  It’s not always a reliable indicator of your body’s hydration levels.  How much water?  Again that depends on your exertion level, time and distance but a minimum amount should be 12 ounces.

• Drink water after you’ve concluded your routine.  Perhaps as much as another quart if you’ve really exerted yourself.

Psychologically it’s often times difficult to get into a routine of drinking water when you’re not thirsty or when it’s cold outside.   So it’s important that you develop a year round standard routine surrounding your water consumption while walking.  Get into a habit of drinking water before, during and after your walk.  Keep the amounts the same in winter and in summer so that it becomes second nature and you don’t have to constantly call it to mind.  It’s important to stay physically active and engaged during the winter months so pull that water bottle back out of you summer walking equipment.  Remember to stay hydrated and stay healthy.
