In one sentence, describe what the following article is about: An important step to staying well-hydrated is to know what your water intake needs are. Keep in mind that the basic recommendation of 8 eight ounce glasses of water per day is flexible. You will need to drink more on top of this depending upon the following factors:  How much you exercise. You will need into increase your water consumption when you work out. Your environment. Hotter temperatures, such as during hot weather, in a sauna, or even humidified air indoors, require greater water consumption. Your altitude. Higher altitudes are more dehydrating. Pregnancy and breast-feeding, both of which increase your water needs. For an average workout, you will need 1.5 to 2.5 cups of additional water (on top of the 8 eight ounce glasses of water per day that are already recommended). You may need even more than this if the duration of your workout is over an hour, or if it is a workout of particularly high intensity.  Note that, for workouts that are very intense or longer than one hour in length, an electrolyte sports beverage is preferable to water to maintain your hydration. This is because intense exercise causes you to lose a lot of salt through sweat. Without adequate salt, regardless of how much water you drink you will be unable to effectively absorb it through your digestive tract. Therefore, to compensate for lost salt, the electrolytes in the sports drink (such as Gatorade or Powerade) are key, and will help you to absorb the water you are drinking more efficiently. It is important to know that illnesses - particularly ones that involve diarrhea and/or vomiting - require exceptional efforts to stay hydrated. If you only vomit once or a couple of times, such as during a food poisoning attack, it is less worrisome than an ongoing illness of three to five days with consistent diarrhea and/or vomiting (such as the Norwalk virus or other gastrointestinal illnesses).  If you have a gastrointestinal flu, you will need to make a big effort to stay hydrated at this time. Your best bet is an electrolyte sports drink rather than pure water because, similar to intense endurance exercise, you will be losing a lot of salt through diarrhea and/or vomiting. Take small sips frequently throughout the day. If you cannot keep the fluids down or if you are continuing to have diarrhea and vomiting despite efforts to hydrate yourself, then you will need to go to a clinic or urgent care setting for intravenous hydration. In order to adequately hydrate yourself when there is salt loss involved, you will need to replace not only the water, but also the electrolytes (hence why Gatorade, Powerade, or another sports drink is your ideal option). If you have an illness of this nature, sip on fluids consistently throughout the day and consume as much as you are able to. It is better to sip slowly and often than to drink a lot at once, as consuming too much at one time may trigger further nausea and/or vomiting. Note that, in very severe illnesses, you may require IV fluids in a hospital setting to maintain hydration. See your doctor if you are concerned as it is better to be safe than sorry. Other medical and health conditions may also affect your hydration status, though seldom as severely as a gastrointestinal flu. Speak to your doctor if you would like further information as to how your health conditions (such as kidney disease or other chronic diseases) may have an impact on your water consumption and hydration status. If your child is sick, he or she may become dehydrated much faster than an adult and may need to be seen by a physician sooner than an adult would. If your child becomes listless and hard to wake, then emergency medical attention is necessary. If your child has no tears when crying, take her in for an evaluation. Other symptoms of dehydration in children include:  not urinating or urinating less than is usual (an infant might have dry diapers for three hours or more) dry skin feeling dizzy or lightheaded constipation sunken eyes and/or sunken fontanels rapid breathing and/or rapid heart rate The recommended water intake for pregnant women is 10 cups per day (as opposed to the usual 8 cups per day for non-pregnant women). For nursing women, the recommended water intake is 13 cups per day. In both of these cases, you will need additional fluids to support your growing baby, and/or to aid in milk production which uses a significant amount of water.
Summary: Be aware of factors that will affect how much water you need. Drink more when you exercise. Recognize the impact of illnesses on your hydration status. Keep in mind that children can become dehydrated quickly. Consume more fluids when you are pregnant or breastfeeding.

Problem: Article: Is it a word problem? Fraction? Quadratic equation? Determine what categorization best fits your math problem before you move forward. Taking the time to identify your problem type is essential to finding the best way to solve the problem. Even if the problem seems simple, read it very carefully. Don't just skim the problem and attempt to solve it. If the problem is complex, you may need to reread the problem multiple times before you fully understand it. Just take your time and don’t move on until you feel confident that you know what the problem is asking you to do. To help wrap your mind around the problem that you are facing, it may help you to say or write it out into your own words. You can simply say it or write it out if you in a situation where you cannot speak out loud, such as during a test. Check what you have said or written against the original problem to make sure that you are representing the problem accurately. If you think it will help with the type of problem you are facing, create a visual representation of the problem to help determine what you need to do next. The drawing does not have to be elaborate, it can simply be a shape or shapes with numbers. Consult the problem as you draw and check your drawing against the problem after you have finished. Ask yourself, “Does my drawing accurately represent the problem?” If it does, then you can move forward. If not, start over by rereading the problem.  Draw a Venn diagram. A Venn diagram shows the relationships among the numbers in your problem. Venn diagrams can be especially helpful with word problems.   Draw a graph or chart.   Arrange the components of the problem on a line.   Draw simple shapes to represent more complex features of the problem. Sometimes you can identify a pattern or patterns in a math problem simply by reading the problem carefully. You can also create a table to help you identify a pattern or patterns in the problem. Take notes on any patterns that you identify in the problem. These patterns can help you to solve the problem and may even lead you directly to the answer. Check what you have written down against the problem to make sure that you have accurately copied the numbers and other information. Don't go on to the planning stage until you are certain that you have all of the required information and that you fully understand the problem. If you don't understand the problem, take a moment to look at some examples in your textbook or online. Looking at how other people have correctly solved similar problems may help you to understand what this problem is asking you to do.
Summary:
Identify the type of problem. Read the problem carefully. Paraphrase the problem. Draw the problem. Look for patterns. Review your information.
