You can't play your best when you're thinking about how thirsty you are! If you're going to sports practice, a game, or just working out or playing hard, drink water before, during, and after playing. Be sure to drink some extra water when you're out in warm weather, especially while playing sports or exercising. But if you're sick, or it's warm out or you're exercising, you'll need more. Usually, kids drink something with meals and should definitely drink when they're thirsty. ![]() The amount kids need depends on their age, body size, health, and activity level, plus the weather (temperature and humidity levels). There is no magic amount of water that kids need to drink every day. How Much Is Enough?īecause water is so important, you might wonder if you're drinking enough. Vegetables also contain a lot of water - think of slicing into a fat tomato or crunching into a crisp stalk of celery. Fruit contains quite a bit of water, which you could probably tell if you've ever bitten into a peach or plum and felt the juices dripping down your chin. Any fluid you drink will contain water, but water and milk are the best choices. Your body doesn't get water only from drinking water. And you can bet that water is the main ingredient in perspiration, also called sweat.īesides being an important part of the fluids in your body, water is needed by each cell to work. Water is needed for digestive juices, urine (pee), and poop. You need water to digest your food and get rid of waste. Water is also in lymph (say: limf), a fluid that is part of your immune system, which helps you fight off illness. Water helps keep your temperature normal. Without oxygen, those tiny cells would die and your body would stop working. For instance, your blood, which contains a lot of water, carries oxygen to all the cells of your body. Why? Your body has lots of important jobs and it needs water to do many of them. Water makes up more than half of your body weight, and a person can't survive for more than a few days without it. Without water, your body would stop working properly. All living things must have water to survive, whether they get it from a water fountain, a rain cloud, or a little bottle attached to the side of a hamster cage. The name pufferfish suggests these marine cuties are full of air.īut pufferfish inflate by swallowing water, says Adam Summers of the University of Washington via email.What do you, the trees, and a hamster have in common? Give up? You all need water. This gives the female toad more leeway in choosing her mate. ![]() ![]() (See " Wild Romance: Weird Animal Courtship and Mating Rituals.") Not all this self-aggrandizement is a form of attraction-female cane toads, for instance, go to great lengths to avoid romance.Īccording to a 2010 study in Biology Letters, male cane toads have a tougher time grasping a female who inflates her body. The males most likely inflate the dulaa by diverting air from their respiratory passages, according to a 2006 study in the Journal of the British Veterinary Association. Male Arabian camels sport a dulaa, a part of the soft palate that the animals inflate during mating season to call to and impress females. ![]() Male hooded seals, native to the Arctic and North Atlantic Oceans, have two inflatables: A flap of skin they inflate with their nostrils, which covers their head and a pinkish red balloon blown through one nostril, which attracts females and warns off other males.įor male hooded seals looking for a mate, nothing's manlier than flailing around a hot-pink balloon. The resulting look of this inflated esophagus, though, shares an uncanny resemblance with Santa's beard. (Also see " Unlike Footballs, These Animals Are Meant to Deflate.") The heaviest of all flying birds, kori bustards gulp air to inflate their throats and make their “percussive, booming call-probably useful for communicating across long distances in its typical flat, open habitat in Africa,” Marc Devokaitis, of the Cornell Lab of Ornithology, says via email. Some critters puff up to impress the ladies, like the male kori bustard. I took the author’s prerogative at Saturday’s Weird Animal Question of the Week to ask “How and why do some animals inflate themselves?” For some animals, it takes a couple of seconds. For humans, bulking up takes months at the gym.
