There are also certain times when people may need more water than usual, whether it is a health condition, or an environmental concern.
We should take more water:
--- When on a high protein dietDid you know that uric acid in meat could cause gout? That said, people on a high protein diet require more water than a regular eater, as the water will flush out things like uric acid, caused by the extra protein. Another risk of high protein diets that can be combated with water is that, if you're not eating carbohydrates, your body breaks down fat cells and then produces a buildup of toxic chemical compounds, called ketones in your blood. When there are too many ketones in your blood, your body eliminates them in your urine. Eliminate too many ketones, and you also eliminate too much water. Without replacing it, you can suffer severe dehydration and the risk of abnormal heart rhythms
---- When on a high fiber dietConstipation can be an uncomfortable side effect of high fiber intake. That is because fiber, although good for your health, can absorb fluid from your intestines. Drinking fluids help prevent constipation in those who are eating high fiber.
--- Having an illness that causes vomiting or diarrheaVomiting and diarrhea are signs of dehydration. Drinking more water will keep the body hydrated during this illness, and also prevent that vomiting and diarrhea that goes along with it. It is suggested that someone with these symptoms, most likely from the flu or another virus, to drink 2-3 quarts of water per day.
--- Being more physically activeThe more active someone is, the more they will perspire. When you exercise, your body builds up heat, and sweat brings your body temperature back to normal. As sweat evaporates from your skin, your body cools. But, through the cooling process, can lose four cups of water every hour during exercise. As a result, more water is lost. Drinking more fluids will combat that water loss by replenishing the body. Whether this activity is during a workout or during work, keep drinking.
--- Exposed to warm or hot conditionsAs people are exposed to warmer conditions, their body temperatures will rise as a reaction to cool the body, resulting in more perspiration. This can happen whether they are being active or not. Without proper fluid intake, this change in climate could leave people having the uncomfortable effects of dehydration. That is not something someone on a vacation wants to experience! Carry around a water bottle while in warmer conditions. Also, warmer conditions could be in a workplace. If that is the case, always make sure that you are paying a visit to the water cooler, or have a water bottle at your workstation.
