If it is clean, fresh snow, it is safe to drink. This is basically drinking rain water. It hasn't had time to pick up pollutants when it is newly fallen. I live in New England, and kids do this all the time. You get taught early to only do this with white snow. Make sure that the snow is actually clean: the longer it sits, and the more urbanized an area is, ...

Pee on it. To keep the water drinkable, you'd want to have the liquids separated but still have good thermal transfer between them. A well equipped traveller will pick his/her thermos bottle and a condom, pee in the condom (ladies would probably do it the other way around), tie the condom and put in the bottle, fill the rest with snow, cap, wait and drink. ...

The best way to melt snow is to put it in a bottle inside your jacket under your mid layers while you're on the move and let your body heat melt it. Do not place it against the skin, leave a layer or two between you and the bottle. It's advisable to always leave your bottle in your jacket in subzero temperatures where it can freeze if left in your bag. ...

From a water purity point of view the same rules apply for drinking water. What is important though is the temperature. If you drink large amounts of snow at a low temperature (i.e. you don't heat it adequately and just drink it as it melts in your hand) then you may need to be careful. Basically if the temperature is low enough and you're ingesting large ...

Stay hydrated. Dehydration prolongs the time it takes to recover from exertion. Eat. Make sure you bring enough and the right kind of food for the trip to adequately fuel your body. Sleep. Make sure you didn't skimp on sleep, just to get that extra early start. Prepare your body. Go on long hikes or runs back to back in the weeks/months leading up to your ...

As already explained in the other questions, the primary concern is possible contamination. For fresh snow and far from civilization this is very easy to identify: White is good: yellow, brown, ... not so :) Close to roads/industry there might be a non-visible contamination but unlikely to be harmful for occasional consumption (at least in countries with ...

Your goals should be to: Recuperate as fast as possible and prevent injury Replenish your energy reserves as best you can Rest So stretch and stretch well (even if your exhausted). I recently did a long distance walk and I was too tired to stretch in the evening. Worst decision I've ever made. I woke up after about an hour of sleep, I thought I'd torn my ...

Physically there are two ways for you to heat up the snow: by heat conduction and by heat radiation. Conduction means you place it somewhere close to your body. It does not matter whether this is directly in your mouth or on your belly, you will lose the same amount of energy. The only option to heat it up without losing additional energy is by radiation, ...

Very simply: if you eat snow, all the energy that would be melt the snow is energy currently in your body. Lots of heat loss direct from your body. If you put snow in an outer layer of your clothes, then much of the energy that would melt the snow is energy that was in the process of escaping to the outside air. Effectively the snow is capturing some of ...

You are experiencing a strain of the LCL, the Lateral Collateral Ligament that connects your femur to your fibula with IT Band syndrome. The mechanics of going downhill when hiking are significantly different than up. When taking a step down from a height of more than 6 inches, the femur tends to stay perpendicular to the ground, under the hip joint while ...

I have low blood pressure, 90/60 read to me just one week prior to going mountain hiking in Palm Springs California (8,500 ft. elevation). I did not experience the tiredness or lack of oxygen I thought that I would. I seemed to have the same energy as I usually have without any adverse symptoms associated to what many would complain as thinner air at that ...
