Healthy Myths vs. Facts

Warm Weather vs. Cold Weather
Myth: When engaging in outdoor recreation, you only need to worry about drinking enough water only during warm weather sports and activities.
Fact: Outdoor winter activities require at least as much water as outdoor activities during the rest of the year. Your body loses fluids when inhaling cold winter air, particularly during days when humidity is low and air is crisp and dry.

What about Fruit Juice?
Myth: Drinking fruit juice is a good way to meet the majority of your body’s fluid requirements as long as it is 100% juice.
Fact: While it’s true that fruit juice has high water content, the calories can add up quickly making it poor choice as a hydrating beverage. Try diluting a few ounces of your favorite fruit juice plenty of water or making a spritzer by adding a few ounces of fruit juice or nectar to a tall glass of seltzer.

Bottled Water Safety
Myth: Bottled water is safer than tap water.
Fact: Most bottled waters are safe, but it depends on where the water comes from, how it’s treated and whether or not it is tainted. In fact, an estimated 25% or more of bottled water is really just tap water in a bottle – sometimes treated, sometimes not. A recent survey by the Natural Resources Defense Council found that out of 103 brands of water tested, one-third contained significant contamination. If you’re buying bottled water, choose a major brand from a store that sells a lot of water. Once you drink from a bottle, refrigerate it, and finish it within one or two days.

Reusing Water Bottles
Myth: There’s nothing wrong with rinsing out and reusing plastic water bottles.
Fact: Reusing and refilling empty water bottles seems like a responsible practice since it helps reduce wasteful discarding of plastic. However, according to the International Bottled Water Association, these bottles, made from polyethylene terephthalate (PET), are intended for onetime use. Over time, the plastic loses its integrity and develop cracks of leaks. In addition, they are difficult to wash and dry due to a narrow neck. If not properly sanitized, they could harbor bacteria. It’s true that water is not the most likely environment for bacteria to grow in, but since water bottles come in contact with the mouth, particles of food mixed with saliva could flow back into the bottle where-under the right conditions, such as warm temperatures or even room temperature-bacteria could thrive. If you want to be environmentally conscious, purchase a reusable water bottle sold in bike shop or outdoors/sporting goods stores.
