Water is perhaps the most important nutrient necessary for human survival. After all, our bodies are made up of almost 60% water. The importance of staying hydrated cannot be understated, as it facilitates everything from maintaining body temperature to transporting nutrients. But how much water should we be drinking each day? In this article, we will explore the various guidelines, recommendations, and factors that affect water intake. We will also discuss the importance of moderation and suggest methods for tracking hydration. By the end, you will have all the information you need to stay hydrated and healthy.

The standard recommendation

You’ve probably heard the old adage about drinking “eight glasses of water a day.” But where does this recommendation come from? And is there any science behind it?

The truth is that there is no hard and fast rule for how much water we should all be drinking each day. However, this recommendation is widely accepted and has been for decades. It is thought to have originated from a 1945 report from the National Research Council, which suggested 1 milliliter of water for every calorie consumed. This equates to roughly 8 cups a day for the average person.

Despite its popularity, the “8 glasses a day” recommendation has been subject to criticism and controversy. Some argue that it is too simplistic and doesn’t take into account individual needs and differences.

Factors that affect water intake

Not everyone needs to drink the same amount of water each day. In fact, individual needs can vary greatly depending on factors such as age, weight, activity level, and climate.

For instance, athletes and those who engage in physical activity may need more water to compensate for fluid loss through sweat and respiration. As we age, our sense of thirst may diminish, making it easy to become dehydrated without realizing it. Those in hot and humid environments will also need to drink more water to maintain hydration levels.

So how much water should you be drinking each day? Here are some general guidelines:

  • Children aged 4-8: 5 cups per day
  • Children aged 9-13: 7-8 cups per day
  • Girls aged 14-18: 8 cups per day
  • Boys aged 14-18: 11 cups per day
  • Women aged 19+: 8-11 cups per day
  • Men aged 19+: 12-16 cups per day

It’s important to note that these are just general recommendations. Your individual needs may vary, so it’s best to pay attention to your body and drink when you’re thirsty.

Staying hydrated through food and beverages

While drinking water is important, it’s not the only way to stay hydrated. In fact, we can get up to 20% of our daily water intake from food alone!

Foods that are high in water content are great for hydration. These include fruits like watermelon, strawberries, and oranges, as well as veggies like cucumber, celery, and lettuce. Soups, smoothies, and teas are also great for hydration.

In terms of beverages, of course, water is the best option. But if you’re not a fan of plain water, try infusing it with fruits or herbs for added flavor. Coconut water is another great option, as it’s high in potassium and electrolytes.

Dehydration warning signs

Dehydration can have serious consequences, including everything from headaches to heat exhaustion. Knowing the warning signs of dehydration can help prevent more serious complications. These include:

  • Thirst
  • Dry mouth and throat
  • Dark yellow urine
  • Dizziness or lightheadedness
  • Headache
  • Fatigue

If you’re experiencing any of these symptoms, it’s important to slow down and drink some water. Avoid sugary drinks or caffeine, as they can actually dehydrate you further.

Water tracking methods

One way to ensure you’re getting enough water each day is to track your intake. There are several methods for doing this, including using smartphone apps, using water bottles with measurement markers, or simply setting reminders throughout the day.

Some popular hydration tracking apps include WaterMinder, MyWaterBalance, and Plant Nanny. These apps allow you to input your daily water goal and track your progress throughout the day.

If you prefer a more analog option, investing in a water bottle with measurements on the side can be helpful. This way, you can easily see how much you’ve already drunk and how much you have left to go.

Setting reminders on your phone or computer can also be helpful. You can set alarms to go off every hour or so to remind you to drink some water.

While tracking your water intake can be a helpful tool, it’s important not to become too obsessed with it. The goal is to establish healthy habits and stay hydrated, not to stress yourself out over hitting a certain number.

The importance of moderation

While staying hydrated is important, it’s possible to overdo it. Drinking too much water can lead to a condition called hyponatremia, which is when the sodium levels in the blood become too diluted. This can cause symptoms like headaches, nausea, and confusion.

To avoid overhydration, it’s important to take a balanced approach to water consumption. Drink water when you’re thirsty, but don’t force yourself to drink more than your body needs.


Staying hydrated is one of the most important things you can do for your overall health and wellbeing. By paying attention to your individual needs and staying mindful of hydration throughout the day, you can establish healthy habits that will keep you feeling your best.
