🚰 The Importance of Hydration

Water is the foundation of life, making up a significant portion of our bodies.

It plays a crucial role in various bodily functions, such as regulating body temperature, aiding digestion, transporting nutrients, and flushing out toxins.

Since water is so vital for the body to function properly, when we don’t drink enough water we may have a variety of dehydration symptoms.

Dehydration can lead to fatigue, dizziness, headaches, and even more serious health complications if left untreated.

💧 Daily Water Intake Recommendations

While staying properly hydrated is important for many reasons, drinking a gallon of water per day is not necessary for everyone. In fact, daily water intake recommendations vary from individual to individual.

Water intake will vary from person to person depending on gender, age, climate, physical activity level, various health conditions, illness (diarrhea, vomiting, elevated body temperature), and whether you are pregnant or breastfeeding.

It is important to recognize if you are physically active or sick this likely will require increased fluid intake.

For the most part, if you drink 8 to 12 cups of water per day, this should be enough to meet daily hydration needs. It’s important to recognize that a large portion of adults do not drink enough water daily.

🤔 Should You Drink A Gallon of Water a Day?

As mentioned above daily fluid intake is essential to many body processes, however not everyone needs to drink a gallon of water per day to maintain proper hydration. With this said, for most healthy individuals even though it may not enhance your hydration, drinking a gallon of water per day will not do any harm.

However, for most individuals, it can be challenging enough to hit the 8-12 cups of water per day.

The “WUT” Rule

The best practical ways to make sure you are maintaining hydration is paying attention to your body weight, urine and thirst AKA “WUT”. If you urinate infrequently or your urine color is dark, this indicates you aren’t staying hydrated and likely need more.

However, if you urinate several times throughout the day and it’s a pale yellow, you are likely staying well hydrated and additional water intake wouldn’t provide any additional benefit.

Also paying attention to your weight before and after exercise can be a great way for you to know how much water was lost through perspiration and performance. If you’re thirsty this is also your body’s natural way of letting you know – “I need more water”.
