Importance of Hydration and Tips for Staying Hydrated

Published On September 16, 2013 | By Hannah Ellsbury | News

Why is it so important to stay hydrated?

Your body depends on water for survival. Did you know that water makes up more than half of your body weight? Every cell, tissue and organ in your body needs water to function correctly. For example, your body uses water to maintain its temperature, remove waste and lubricate joints. Water is essential for good health.

How does my body lose water?

You lose water each day when you go to the bathroom, sweat, and even when you breathe. You lose water even faster when the weather is really hot, when you exercise, or if you have a fever. Vomiting and diarrhea can also lead to rapid fluid loss. If you don’t replace the water you lose, you can become dehydrated.

How do I know if I’m dehydrated?

Symptoms of dehydration include:

  • Little or no urine, or urine that is darker than usual
  • Dry mouth
  • Sleepiness or fatigue
  • Extreme thirst
  • Headache
  • Confusion
  • Feeling dizzy or lightheaded
  • No tears when crying

Don’t wait until you notice symptoms of dehydration to act. It can be hard to recognize when you’re dehydrated, especially as you age. Actively prevent dehydration by drinking plenty of water.

How much water should I drink each day?

There are different recommendations for water intake each day. Most people have been told they should be drinking 6 to 8 8-ounce glasses of water each day, which is a reasonable goal. However, different people need different amounts of water to stay hydrated. Most healthy people can stay well hydrated by drinking water and other fluids whenever they feel thirsty. For some people, fewer than 8 glasses may be enough. Other people may need more than 8 glasses each day.

Some people are at higher risk of dehydration, including those who exercise often, have certain medical conditions, are sick, or are not able to get enough fluids during the course of the day. Older adults are also at higher risk. As you age, your brain may be unable to sense dehydration and send the signals for thirst.

If you are concerned that you may not be drinking enough water, check your urine. If your urine is consistently colorless or light yellow, you are most likely staying well hydrated.

You may need to increase the amount of water you are drinking if you:

  • Have certain medical conditions, such as kidney stones or bladder infection
  • Are pregnant or breastfeeding
  • Are going to be outside during hot weather
  • Are going to be exercising
  • Have a fever, or have been vomiting or have diarrhea
  • Are trying to lose weight

Besides water, what else can I consume to stay well hydrated?

Water is the best option for staying hydrated. There are other drinks and foods that can help provide the water you need, but some may add extra calories from sugar to your diet.

Drinks like fruit and vegetable juices, milk and herbal teas can contribute to the amount of water you should get each day. Even caffeinated drinks, such as coffee, tea and soda, count toward your daily water intake – up to a point. But it’s best to limit these since caffeine may cause some people to urinate more frequently, or feel anxious or jittery. A moderate amount of caffeine, 200 to 300 milligrams (about the amount in 2 to 4 8-ounce cups of coffee), is not harmful for most people.

Water can also be found in fruits and vegetables, such as watermelon, tomatoes and lettuce, and in soup broths.

Tips for staying hydrated

  • Keep a bottle of water with you during the day. Consider carrying a reusable water bottle and filling it from the tap rather than purchasing bottled water, which is expensive and creates plastic bottle waste.
  • If plain water doesn’t interest you, try adding a slice of lemon or lime to your drink.
  • If you’re going to be exercising, make sure you drink water before, during and after your workout.
  • Start and end your day with a glass of water.
  • When you’re feeling hungry, drink water. The sensation of thirst is often confused with hunger. True hunger will not be satisfied by drinking water. Drinking water may also contribute to a healthy weight loss plan, as some research suggests drinking water will help you feel full.
  • Drink on a schedule if you have trouble remembering to drink water. For example, drink water when you wake up; at breakfast, lunch and dinner; and when you go to bed. Or drink a small glass of water at the top of each hour.
  • Drink water when you go to a restaurant. Not only does it keep you hydrated, but it’s free!
