Water - How Much Do I Really Need to Drink?

 

Water is essential for life. You can only survive a few days without it. And being hydrated is essential for health. I could argue that water is the most essential nutrient of them all. Water is required for every cell and function in your body.

 

It is a huge component of your blood; it cushions your joints and aids digestion. It helps stabilize your blood pressure and heart beat. Water helps to regulate your body temperature and maintains electrolyte (mineral) balance. And that's just a few of its roles.

 

Dehydration can impair mood and concentration, and contribute to headaches and dizziness. It can reduce your physical endurance, and increase the risk for kidney stones and constipation. Extreme dehydration can cause heat stroke.

 

So, water is critical for life and health.

 

But, just as way too little water is life-threatening, so is way too much. As with most things in health and wellness, there is a healthy balance to be reached.

 

But, there are conflicting opinions as to how much water to drink. Is there a magic number for everyone? What counts toward water intake?

 

Let’s dive right in.

 

How much water do I need?

 

Once upon a time, there was a magic number called "8x8." This was the recommendation to drink eight-8 oz glasses of water every day; that's about 2 liters of water.

 

Over time, we've realized that imposing this external "one size fits all" rule may not be the best approach. Now, many health professionals recommend drinking according to thirst. You don’t need to go overboard forcing down glasses of water when you’re not thirsty. Just pay attention to your thirst mechanism. We have complex hormonal and neurological processes that are constantly monitoring how hydrated we are. And for healthy adults, this system is very reliable.

 

Besides thirst, pay attention to how dark and concentrated your urine is. The darker your urine, the more effort your body is making to hold on to the water it has. Urine is still getting rid of the waste, but in a smaller volume of water, so it looks darker.

 

There are a few other things to consider when evaluating your hydration status. If you’re sweating a lot, or are in a hot/humid climate drink more. Also, remember to replenish your electrolytes as well! Simply drinking coconut water is the easiest way to do this. Breastfeeding moms, elderly people, and people at risk of kidney stones need to drink more water too. So do people who experience vomiting and/or diarrhea, as both can quickly dehydrate our bodies.

 

So, ditch the “one size fits all” external rule, and pay more attention to your body’s subtle cues for water.

 

What counts toward my water intake?

 

All fluids and foods containing water contribute to your daily needs.

 

Water is usually the best choice. If you're not drinking pure water, consider the effects that the other ingredients have on your body. Drinks containing sugar, alcohol, and caffeine will have effects besides hydration. Sugar can mess with your blood sugar balance. Alcohol can make you feel "buzzed." And caffeine can keep you awake. Let's talk a bit more about caffeine for a second.

 

Caffeine is the infamous "dehydrator," right? Well, not so much. If you take high dose caffeine pills, then sure, they cause fluid loss. But the idea that coffee and tea don't count toward your water intake is an old myth. While caffeine may make you have to go to the bathroom more, that effect isn't strong enough to negate the hydrating effects of its water. Plus, if you're tolerant to it (i.e., regularly drink it) then the effect is even smaller. So, you don’t need to counteract your daily cup(s) of coffee and/or tea. So your morning latte is safe! J Or in the case of the June/July heat streak, your iced coffee!

 

Also, many foods contain significant amounts of water. Especially fruits and vegetables like cabbage, cantaloupe, watermelon, strawberries, celery, spinach, lettuce, apples, pears, oranges, grapes, carrots, and pineapple. These foods are over 80% water, so they are good sources of hydration. There is nothing like watermelon slices on a hot summer’s day!

 

So, you don’t need to count your plain water intake as your only source of hydration. All fluids and foods with water count.

 

Conclusion

 

There is no magic number of the amount of water you need. Everyone is different. Children, pregnant women and elderly people require more.  Episodes of vomiting or diarrhea will also increase your short-term need for more water.  The most important thing is to pay attention to your thirst. Other signs you need more water are dark urine, sweating, constipation, and kidney stones.

 

Water is your best source of fluids. But other liquids, including caffeinated ones, help too. Just consider the effects the other ingredients have on your health as well. And many fruits and vegetables are over 80% water so don't forget about them.
