Introduction
People wonder how much water to drink every day in order to stay healthy; the answer may not be exactly simple, according to nutrition experts. Read the article to know the current nutritional recommendations for drinking water based on different age groups and how to prevent dehydration.
What Are the Metabolic Functions of Water?
Your body comprises more water than any other element, that is—almost around 55 percent to 60 percent of your total body weight would be attributed to water alone, depending on your gender as well. Water primarily helps regulate not just your body temperature or is essential to the mechanism of homeostasis, but it also helps in the transport of nutrients, providing a medium to eliminate all the toxic waste from the blood. Every day you would be losing water in different ways, even as you breathe, sweat, urinate, or even defecate
These amounts of water that are lost from your body need to be replenished to prevent you from being dehydrated. Current scientific research further shows that the link between aging and dehydration is becoming more evident in medical literature because as Individuals age, especially the geriatric population groups - they would be more easily prone to dehydration because of the lowered metabolic rate. Though water intoxication that leads to dangerous or life-threatening states like hyponatremia is indeed a possibility in individuals who drink water excessively during the day (beyond the upper limit of 8 to12 ounces of water), it is still rare because most of the individuals do not tend to drink water beyond the usual requirements.
Now let us explore in this article the exact hydration requirements that have been recommended by nutrition experts to ensure that you are drinking enough water.
What Are the Water Requirements for Different Age Groups?
Diet and nutrition have a major role to play in fulfilling your daily hydration requirements. Almost a whopping 20 percent of your water intake is derived from the daily foods that you consume and not alone from the water you drink. The remaining water intake which is almost 80 percent tends to be derived from other beverages, water, or any other liquid product that you may be consuming, like juice, coffee, tea, milk, etc. According to the information given by the Institute of Medicine of the National Academy, after extensive reviews and years of research, the scientific evidence on adequate water intake has established certain recommendations for healthy individuals to fulfill their course of "total daily water intake" (including food and beverages). It is important to always consult your registered healthcare professional or nutritionist for personalized advice because your dietary and hydration needs may vary depending on your individual medical history and mainly the physical activity levels regularly. As you may know, women's breastmilk is mostly water. Women will need to drink extra water during this dynamic phase of nursing life or incorporate more liquid or healthy beverages while they are breastfeeding. The Institute of Medicine recommends that all breastfeeding women consume at least 13 cups of fluids in a single day. Pregnant women also need at least 12 to 13 cups of fluids daily (10 cups from normal water and other beverages), according to the current recommendations by the Institute of Medicine for sustaining a healthy pregnancy and maternal health.
Some people would be afraid during the pregnancy phase to drink adequate water because of misconceptions linked in nutrition to the fact of retaining extra fluid during pregnancy or water accumulation that can lead to some swelling, but these are nutrition myths because when you stay well hydrated during this dynamic phase as suggested by your registered healthcare professional, you are also likely to ensure both maternal and fetal health.
-
Children (1 to 3 Years): Five to six cups per day of water, around four cups of water from total beverages.
-
Children (4 to 8 Years): Around seven cups per day of total water, with at least five cups as total beverages, inclusive of drinking water.
-
Girls (9 to 13 Years): Nine cups per day of total water, with seven cups as total beverages, inclusive of drinking water.
-
Girls (14 to 18 Years): Ten cups per day of total water, from eight cups as total beverages, inclusive of drinking water.
-
Boys (9 to 13 Years):Ten cups per day of total water, with approximately eight cups as total beverages, inclusive of drinking water.
-
Boys (14 to 18 Years): 14 cups per day of total water, with 11 cups as total beverages, inclusive of drinking water.
-

Why Athletes Require More Hydration?
It is important to note that individuals who are into a more active lifestyle or who are more physically active, such as athletes/sports players, fitness enthusiasts or bodybuilders, etc will have increased physical activity and more energy expenditure, because of which exercise or manual labor can increase the amount of fluid that is lost as sweat. Your hydration requirements would then definitely be increased. Nutrition experts currently recommend that it is best to drink 2 to 3 cups of water before you start your sports or physical workouts before the activity begins, and you can also continue to hydrate while you are active or in the midst of your physical activity. In fact, you might need an additional cup of water or more every 15 minutes or so if you have been working out or exercising or you are playing sports in places with extreme temperatures.
What Are the Dehydration Symptoms?
It is important for Individuals to primarily recognize the clinical symptoms of dehydration including the following:
-
Excessive sweating (that is caused commonly by exercising in hot weather conditions).
-
Pyrexia/fever.
-
Vomiting or diarrhea.
-
Frequent urination or even excess urination (caused by systemic conditions like diabetes or certain medications like diuretic drugs).
Conclusion
To conclude, goal-setting of hydration is important for individuals of all groups, and it is better to follow the general rule of thumb, that is to drink at least eight-ounce glasses of water per day, and then make up for the remaining amounts of water you drink through a preference for low-calorie beverages, unsweetened fruit or vegetable juices, teas, or electrolytes. It is important to balance your hydration requirements overall to sustain your systemic health and follow your body cues to relieve the feeling of thirst.
