How to buy outdoor sports water equipment 1 1, kettles and water bags can be used all year round.
If it is not an insulated kettle, it is better to use it in spring, summer and autumn. Kettles sold in the market generally have good sealing performance. If it is used in winter, the water in the kettle will expand a lot when it freezes at a very low temperature, which will easily make the kettle expand and deform, thus losing its due role. Therefore, in winter or high altitude cold areas, we should choose a kettle with thermal insulation performance. Of course, for short-term outdoor activities in cold weather, it is still possible to add a heat preservation cover outside the kettle, but once the water in the water vessel is found to be frozen, the water in the bottle should be emptied immediately.
2. Water vessels can only hold cold water.
For the kettle with general plastic liner, it is opposed to filling boiling water, because the plastic liner will make the filled boiling water have a strange smell of plastic; For metal kettles without liner coating, boiling water and cold water can be filled; For the top-grade kettle with anti-corrosion coating, the manufacturer introduced that boiling water would damage the coating, but in our actual measurement, it was found that the inner coating was not obviously damaged when hot water was poured into the coated kettle repeatedly.
Leather water bags are actually wrapped in leather, which is wrapped in edible plastic. It is not recommended to let go of water. As for the high-grade plastic water bag specially designed for outdoor use, it can hold boiled water without any peculiar smell.
3. Water vessels can only hold water.
Some kettles are coated with antiseptic and can be filled with carbonated drinks or fruit juice. Anticorrosive coating can not only prevent the fruit juice from deteriorating, but also prevent the sugar in the beverage or fruit juice from corroding the kettle. However, we don't recommend that you often use a kettle to fill carbonated drinks or fruit juice, so that the inner container of the kettle will slowly leave a layer of attachments, which is more difficult to clean. It strongly opposes putting tea or coffee in the kettle. The dirt left behind is very stubborn, which is extremely troublesome to clean. If you are not careful, it will damage the coating on the inner wall of the kettle.
Kettle is more suitable for outdoor sports lovers than water bag.
The material used to make the kettle is generally hard, so it won't be damaged or leaked when bumping. However, the size of the kettle is fixed, and a large kettle will occupy a space that is not very rich in your backpack, and it is not particularly convenient to carry.
The advanced plastic water bag is second to none in convenience. You can put the water bag in the backpack behind you, and you can drink it directly by winding the drinking port around the front through a special soft drinking pipe. However, a fatal weakness of this kind of water bag is fear of pricking, so don't forget to buy a matching water bag cover at the same time when you buy it.
5. All kettles have anticorrosive coating.
Only the inner coating of some high-grade kettles has anti-corrosion function. At present, there are mainly two kinds of kettle coating processes on the market: one is hot melt spraying, that is, the coating material is heated and melted, and then sprayed on the inner wall of the kettle by electrostatic spraying; The second method is solvent method, that is, the paint is dissolved in chemical solvent first, and then brushed on the inner wall of the pot, just like painting. The former is slightly better than the latter.
6. A good kettle can prevent the water in it from deteriorating.
Generally speaking, the advertisements of high-end kettle manufacturers claim that the water in the bottle can be stored for seven days without any odor, but they avoid "what kind of water is this?" According to our actual measurement, if it is pure water in the water dispenser, it does not smell after seven days. For the flowing stream in the wild, put it in the bottle for three days after boiling, and there is no odor, but there is some precipitation in the water; Wild flow, put directly into the bottle, will precipitate in less than two days, and there is a faint smell. Therefore, no matter how good the kettle is, it should be filled with pure water or boiled fresh water as much as possible. The fresh water that has been kept in the bottle for a long time should be replaced at the place where water is supplied.
How to choose and buy outdoor sports equipment 2 questions about drinking water methods
Store water before exercise.
Drinking enough water before exercise and storing some water in the body can reduce the temperature rise during exercise and reduce the risk of dehydration. You can drink 300-500 ml of water (about a bottle of mineral water) one or two hours before exercise. If it is outdoor sports with hot weather and plenty of sunshine, or special sports such as high-temperature yoga, it is best to drink 200-300 ml more. But drink it in small quantities and many times. If you drink too much at one time, you will feel upset and nauseous, and you will soon want to go to the toilet, so the water will not stay.
Replenish water at any time during exercise.
Drink water at any time during exercise to supplement consumption. According to the degree of sweating, drink it once every 10-20 minutes, and each time is about 150-300 ml (two gulps are almost 150ml). Drinking water like this is a slow tonic, the internal environment is relatively stable, the blood volume will not change much, and it will not increase the burden on the heart and gastrointestinal tract.
Drink enough water after exercise.
Replenishing enough water after exercise will help the body recover from fatigue as soon as possible. But it needs to be used several times, because the water absorbed by the gastrointestinal tract is at most 800ml per hour. Drinking a lot of water at a time will dilute the blood, increase the blood volume at once and increase the burden on the heart. And it will increase the amount of urine. With urine, it will increase the discharge of water and sodium. Drink 300-500ml water slowly for about an hour.
General principles of scientific drinking water
Drink a small amount of water many times at any time.
Don't wait until you are thirsty to drink water. When the weather is hot and you sweat a lot, you should increase your drinking water by 300-500ml. When exercising, you should slowly replenish the water your body needs three times before, during and after exercise. The most taboo is: drink a lot of water at a time after being hot and thirsty!
Another thing to note is that the temperature of water should be as good as room temperature, otherwise it will be very irritating to the gastrointestinal tract. It's too hot. If you like to drink cold food, you should not drink it below 15℃, and you should not drink too much at once. Too cold water entering the body will cause the blood vessels in the gastrointestinal tract to contract sharply, which may cause spasm and pain in the stomach, and cause discomfort in many body organs.
