Great Idea for Preventing Frozen Water Bottles

Monday, December 12, 2011

Last week I presented some tips for preventing water bottles from freezing solid while hiking in cold weather.

In the posting I mentioned that if you’re storing water bottles in your backpack on a very cold day, you may need to insulate them to prevent them from freezing. Using an old wool sock will work. I also mentioned that you may want to turn the bottle upside down to prevent the water from freezing at the neck.

A couple of days after publishing this blog I learned of another trick. This comes courtesy of Christian Vande Velde, the pro cyclist and Tour de France veteran. Vande Velde told the Wall Street Journal that he spends part of his off-season training in his hometown of Chicago - in the dead of winter. Vande Velde said that he combats frozen water bottles by adding a half shot of Grand Marnier to the bottle before leaving his house.

I think he might be on to something!

Study Confirms BPA Linked to Heart Disease

Tuesday, January 19, 2010

National Geographic News is reporting that Bisphenol-A, or BPA - a common, human-made chemical that enters most of our bodies everyday - has been linked to heart disease according to a new study.

The study comes as the U.S. Food and Drug Administration - which has until now maintained that BPA is safe at low levels - announced this past Friday that the FDA has some concerns about the impacts of BPA on developing fetuses, infants, and children. The agency is also urging consumers to reduce their exposure to the chemical until further studies are completed.

BPA is commonly used in consumer plastics, particularly polycarbonate plastic items such as many sunglasses, reusable bottles, food packaging, and baby bottles. It also lines the inside of food cans.

It's probably a good idea that you check all of the water bottles/containers that you use for hiking, cycling and gym exercise just to be safe. You can look at the recycling code on the bottle (usually on the bottom) to determine if it contains BPA. #7 is the type that may contain BPA (and the code may look like the image on the right). Most store-bought water bottles are not #7. It's typically the hard polycarbonate plastics that contain this type of plastic.

You can read the full story by clicking here.

However, I should note that the American Council on Science and Health is stating on their website that:

“Contrary to the authors' press release, they can't make a cause and effect link based on this because it's a cross-sectional (one-time) study, the farthest thing from a controlled trial. Further, the number of participants was tiny. And no one has addressed the absence of any biological basis for this ostensible link: if BPA is an 'estrogen mimicker' as these authors believe, why would tiny amounts of it 'cause heart disease'? The whole thing is overblown, and the media that trumpet this story are just hitching their wagon to anti-BPA activist groups.”

“Here we have the FDA teetering on their latest decision about BPA, and they see all these articles talking about heart disease and other bogus connections,” says Dr. Whelan. “They are under a lot of pressure from junk science on this.”

There's no denying that many medical and scientific studies have proven to be false over the years. However, with something like this, it's just too easy to be safe rather than sorry. I just threw out the one bottle with a #7 we had in the house.

Trail Tested: Hiking Hydration Options

Monday, September 1, 2008

No comments
One of the most important things while hiking is staying properly hydrated. Hiking in any type of weather depletes your body of liquids. To replace those lost fluids you need to drink frequently. If you wait until you feel thirsty you’re more than likely already dehydrated. The more dehydrated you become, the less efficient your body is at cooling itself down. Your endurance decreases and your body becomes less efficient at walking as well. Dehydration can cause muscle cramps, headaches, fatigue, heat exhaustion, heat stroke and even acute mountain sickness. Obviously, dehydration is something you want to avoid.

If you’re hiking for less than an hour under normal conditions, more than likely you’ll only need a standard water bottle for your hydration needs. If you’re hiking for more than an hour, or it’s very hot, or if there’s a lot of climbing involved, you have a couple of choices. You can carry multiple water bottles in your backpack, or you could use Nalgene Bottles, a Platypus, or a Camelbak hydration pack. Each option has its pros and cons.

When I first started hiking, I used Nalgene Bottles to carry extra liquids. Nalgene Bottles are an extremely efficient way to store extra water for hiking. The wide mouth makes it easy to fill, as well as re-filling your drinking bottle. The wide mouth also makes it easy to add ice cubes to your drink.

Nalgenes are also extremely durable. With the possible exception of the loop, which keeps the lid attached to the bottle, it would be very hard to break this product. One additional benefit of Nalgene Bottles is that they dry quickly after use. This is important because you don’t want to trap any liquids in your container while you’re storing it or it will get moldy and smell.

My only complaint with Nalgenes is that they continue to occupy a lot of space in your pack after you’ve used the contents. This really isn’t a big deal, just a personal preference. Because of this, however, I made a switch several years ago to the Platypus. I especially liked this option because the container collapses as you consume your liquids. Once finished, the Platypus takes up virtually no room in your pack.

Although the Platypus is made with a flexible plastic, it’s still very tough. I have two Platypuses that I have stored folded and they still are working fine after several years of uasge. The Platypus can also be frozen or boiled. Furthermore, I have never had a problem with water tasting like plastic.

There are two downsides to using the Platypus. Again, neither of these are big issues. One, it takes two or three days for the container to completely air dry before storing. The second thing to think about is that it takes two hands to pour your water from the Platypus into a water bottle.

Interestingly, Platypus has recently introduced a “Hoser” system, which is very similar to the Camelbak hydration pack, a very popular choice among mountain bikers. The Hoser Hydration System allows hikers to stuff a Platypus in their pack, attach a hose, and create a hands free system. A bite valve allows you to drink without ever having to touch a water bottle. This is an excellent choice if you’ve had problems staying hydrated on hot days because you just don’t drink frequently enough.

The final hydration option is the Camelbak. My wife uses her Camelbak from time to time. The Camelbak company provides you with the option of purchasing a reservoir and tube system that you can stuff in your pack, or a backpack with the Camelbak system already installed within the pack. My wife likes her Camelbak because it holds all the water she needs, and she finds it easier to drink, thus keeping her properly hydrated.

Her biggest complaint is that sometimes the system has the taste of plastic. Also, on hot days, the water that sits in the hose tends to get hot if exposed to the sun. It can also be a challenge keeping the drinking valve clean while out on the trail. Finally, it can also be a challenge getting the reservoir dry after usage.
