Optimal Water Intake

For years, the 8 glasses of water a day has been the benchmark for water intake. However, has this claim been backed by science or is it just a made up number? In today's article, I'll be diving into what the research has to say about the optimal water intake.


The human body is approximately made of 60 percent water. So, keeping hydrated is pretty important when it comes to a person's health. Even a 1 percent loss of fluid can impair a person's mood and also negatively affect their workout performance. When it comes to the 8 glasses a day recommendation, it is just an arbitrary number that has no backing in science. There actually is no optimal water intake due to the fact that each person's body is so different. However, our bodies are pretty smart at preventing dehydration. Our bodies have a thirst mechanism, whenever our body senses a lack of water, thirst kicks in. It's as simple as that. So, an easy way to make sure you're drinking enough water is to drink water when you're thirsty and stop drinking when your thirst stops. Also, make sure to replenish the water you lose while working out. That's all a person needs to do. There is no set number for water consumption. Also, the one gallon a day thing for many people is over kill. Just make sure to be in tune with your body and thirst levels and you will be fine. Don't ignore your body's thirst mechanism.


Lastly, water can be consumed from various sources such as juice, coffee, milk etc. It doesn't just have to be water. Just make sure it isn't alcohol as that is an extremely easy way to get dehydrated. In conclusion, drink when you're thirsty and stop when you aren't.
