Drinking water is an important key to staying hydrated and healthy. While individual needs vary, such as sex and lifestyle, the Institute of Medicine recommends women (aged 19-50) drink 2.7 liters (91 oz.) per day and men (aged 19-50) drink 3.7 liters (125 oz.) per day. [1] It can be challenging to reach that goal, but spreading out your water consumption through the day and finding alternative sources of hydration will help you increase your daily fluid intake.

Drinking Enough Water

  • Drink water periodically throughout the day.
  • Carry a water bottle so you always have water nearby.
  • Flavor your water for some variety.
  • Drink water in small sips to hydrate yourself more efficiently.

Spreading out Water Consumption through the Day

  1. Drinking water right when you wake up will help jumpstart your metabolism as well as rehydrate you after going all night without any liquids. [2] Keep a glass beside your bed or leave a note on your alarm clock to remind yourself.
  2. Have a glass of water with each meal. This will aid in digestion by helping to break food down so that your body can absorb nutrients. Water also softens stool and helps prevent constipation. [3] Remember to drink water along with any snacks you have during the day as well.
    • If you're hoping to lose weight, drink water before you begin eating in order to feel full sooner.

  3. If you work in an office, keep a bottle on your desk and sip from it throughout the day. Set reminders on your computer if you have trouble remembering. If you work a more physical job, try to find a spot to keep a water bottle where you can access it regularly or just carry it with you. [4]
    • For more precise water intake tracking, find a bottle that has measurements marked along the side.
    • Try a bottle with special features like insulation to keep the water cold, a built-in filter, or a separate cylinder inside for infusing your water with fruit.
  4. An additional 1-2 cups (.25-.5 liters) of water is sufficient following moderate exercise, but intense exercise with excessive sweating may require a sports drink, such as Gatorade or Powerade. These beverages contain sodium, electrolytes, and carbohydrates, which will help replace what you lost through sweat. [5]
  5. There are several apps available on your smartphone to help you remember to drink more water. The WaterLogged app allows you to track your daily water intake. Others, like OasisPlaces and WeTap, help you find nearby water fountains where you can refill your water bottle for free. [6]
  6. Every individual needs a different amount of water to stay healthy. But the “8 by 8” rule (8 ounces, 8 times a day) is easy to remember and can help you easily track your water intake each day.
    • Outside the US, this translates to about .25 liters 8 times a day.

    Drinking enough water is essential for optimal health. Water helps to regulate body temperature, transport nutrients, and remove waste. It also plays a key role in maintaining healthy skin, hair, and nails.

Finding Alternative Sources of Hydration

  1. Many people believe liquids with caffeine will dehydrate you, but this is not true when they are consumed in moderate amounts. Water is best, but if you prefer other beverages, such as fruit juice or caffeinated coffee and tea, continue drinking those to reach your daily liquid requirements. [7]
    • Limit your daily caffeine intake to 2-4 cups of coffee or tea daily. Beyond that, you may experience insomnia, irritability, headaches, or other side effects. Children should avoid caffeine altogether. [8]
    • Caffeinated beverages may not be a good source of hydration for those who do not have a developed tolerance to the effects of caffeine. It can be a weak diuretic in the early few days of drinking coffee, but soon tolerance is developed when consumed regularly for 4-5 days, and the diuretic effect disappears. [9]
  2. About 20% of your daily water intake comes from food. [10] Watermelon, celery, cucumbers, and lettuce are good, healthy diet choices that help with hydration. Soups and broths are also a good way to sneak more water into your diet.
  3. If you dislike drinking plain water, a variety of products exist that add flavor or sweetness to a glass of tap water. Some are available as powders while others are liquid additives.
    • Be sure to read the ingredients of these products. Some contain thickening agents like propylene glycol that are considered controversial. [11]
    • If you would prefer something more natural, try cutting up strawberries, lemons, or cucumbers and putting them into your water to infuse it with those flavors.

    Expert Answer
    Generally, no it's not harmful to drink too much water. It in fact, helps you stay healthy and fit. However, if taken in excess, it can lead to hyponatremia, in which the salts, especially sodium, in your body become diluted. This is generally only a concern when combined with intensive exercise.
