Water Keeps Things Cool
People's bodies like to be at about 98.6 degrees Fahrenheit (37 degrees Celsius). But if you're out running around or exercising in warm weather, you can feel pretty hot. And sometimes you don't even need to be exercising - if the weather's warm enough, you can feel hot just sitting still.
And that's where water comes in, by cooling you down with sweat. When your body generates a lot of heat, water comes up through your skin as sweat, and it evaporates into the air. (Evaporation happens when a liquid changes into a vapor - like when water boils and turns into steam.)
As the sweat evaporates, it cools down your skin, which cools down your blood. When your blood is cooler, your insides become cooler, and your whole body cools down. It's like your body's own personal air conditioner!
Replace That Water!
As you can see, water works hard in your body every day. That's why it's important to give your body the water it needs to carry out all its different jobs. On a regular day, your body loses 2 to 3 quarts of water - enough to fill a 2-liter soda bottle. You probably guessed that water is lost when you pee, have bowel movements, and sweat - especially on a hot day.
But your body also loses water in an almost invisible way - evaporation. Water escapes from your body through your skin and in your breath. How? Your breath contains droplets of water that are usually too tiny to see. They become visible for a quick second in the cold when you can "see your breath." But water evaporates this way all year round.
Your skin also contains water, which escapes in tiny droplets that go into the air. If you set a wet sponge on the kitchen counter, after a while, the sponge will dry out as the water evaporates. Likewise, the water in your skin evaporates into the air, but fortunately, your body can replace the water it loses so your skin doesn't dry out.
Eating and drinking is one way to replace the water your body loses. Most foods have a lot of water in them, especially fruits and vegetables. Grapes, watermelon, oranges, and cantaloupe are delicious and full of water. On the veggie side, lettuce, cucumbers, and celery also are full of water.
But you can't rely on food alone to get that water back, and that's why it's also a good idea to drink water every day. You might have heard someone say that people need to drink 6 to 8 cups (1.4 to 1.9 liters) of water each day. Depending on how much water you're getting from foods and other liquids, 6 to 8 cups (1.4 to 1.9 liters) might not be necessary. If you're eating a lot of fruits and veggies, or you like to eat soup every day, you'll be getting some of the water your body needs.
But drinking water is a healthful thing to do - and although you might not need 6 to 8 cups (1.4 to 1.9 liters), water contains no calories, no matter how much you drink.
And what about using other liquids that you like to help you get that water back? Low-fat milk is a good bet, or you can mix seltzer water with juice to make a tasty, sparkling drink. Try mixing half water and half juice for a delicious water-juice combination. Soda and iced tea are OK every once in a while, but you shouldn't drink them too often because they usually come with lots of sugar and caffeine.
Caffeine is a diuretic (say: dye-yuh-reh-tik), which means it makes you urinate more. It's not helpful to be losing water when you're trying to replace it. Calories are another concern in caffeinated drinks, such as soda. Too much of almost any drink - besides water or no-calorie diet drinks - can give you too many calories.
If you're exercising and sweating, drinking water is doubly important (cold water is better). When you sweat a lot, your body loses even more water than normal. The more you exercise and the more you sweat, the more water you'll need to drink. When it's hot or humid, it's even more important to drink water, because you are at a higher risk for heat exhaustion. Here are some guidelines for the amounts of water you should drink before, during, and after exercising:
* 1 to 2 hours before exercising: 10 to 14 ounces of cold water (about a cup and a half, or 295 to 414 milliliters)
* 10 to 15 minutes before exercising: 10 ounces of cold water (about a cup and a quarter, or 295 milliliters)
* While exercising: 3 to 4 ounces of cold water every 15 minutes (about a half of a cup, or 89 to 118 milliliters)
* After exercising: 2 cups (about half a liter) of cold water for every pound of weight loss through sweat and evaporation (this means about a cup or 2 for most kids; if it's a hot day you may feel thirsty enough to drink even more)
When you're exercising, don't wait until you're thirsty to drink up. Did you ever get a very dry mouth and suddenly feel very thirsty? That's because your body already needed water and was trying to tell you by keeping water from going to the salivary glands (these glands make saliva, or spit, which is made from water, remember?). So your mouth felt all dried out, and you had a drink.
But when it's hot or you're exercising a lot, it's much better for you to drink even when you're not thirsty. You'll feel better and have more energy.
Water is great - it helps every cell in our bodies, keeps things moving the way they should, and even cools us down when we need it! Keep your body healthy by drinking enough liquids all the time and especially when you're exercising. With water working for you, you're sure to feel H20-so-cool!

Wrongs could be distinctive between cultures and can exchange over the years. some cultures have confidence that particular nutrients ought to be arranged in a definite way and that's faulty to do in any different case. that faulty my have developed before refrigeration became obtainable and so would now no longer be ideal. nevertheless, there'll be some who carry on with the custom basically with the aid of fact it labored for previous generations. for individuals who believed interior the will for racial purity some human beings it became incorrect to have integrated colleges, shared eating places and lavatories. for individuals who believed in male superiority, it was incorrect for women to anticipate equivalent pay. For populations that have been demise with the aid of fact of affliction or death in conflict and organic disaster, you may think of that homosexuality became discouraged with the aid of fact it diverted sexual ability from reproduction. i think that in case you examine the ten Commandments you will locate that each and each became defined to deter strikes that tended to have undesirable consequences for those societies at that element and probable nonetheless does. in many circumstances, basically as you have defined and to the developed international of the twenty first century, those undesirable consequences look fairly logical. In Biblical cases, in basic terms some understood the logic or had the understanding. Moses became very clever certainly and knew that the long suffering Tribes might never have believed he ought to in my opinion have such understanding yet whilst he defined those with the aid of fact the words of God, properly . . . . . .
