I know it may seem annoyingly basic, but trust me – based on working with patients (and the statistics we have), most people could use this reminder, so don’t click away.
When it comes to making lifestyle changes, it’s easy to feel overwhelmed by where to begin. But one of the simplest and most impactful places to start is hydration if it’s not something already in your routine.
If you caught my recent Instagram video from the “If You Don’t Know Where to Start” series (watch it here), you’ll know that optimizing your water intake is a low-barrier, high-impact habit that supports almost every aspect of your health.
Why Hydration Matters (More Than You Think)
Water is essential for human life—comprising approximately 50–70% of body weight depending on age, sex, and body composition. Maintaining optimal hydration supports:
- Cellular metabolism and nutrient transport
- Temperature regulation through sweating and heat dissipation
- Joint lubrication and tissue protection
- Cognitive function and mood stabilization
- Cardiovascular health by supporting adequate blood volume and circulation
Even mild dehydration—as little as 1–2% loss of body weight—can impair:
- Mental performance
- Concentration
- Physical endurance
- Anxiety and tension
Chronic low-grade dehydration has been associated with:
- Headaches
- Fatigue
- Chronic mood disturbances
- Constipation
- Increased risk of kidney stones and urinary tract infections
How Much Water Do You Really Need?
There’s no universally perfect number because hydration needs are dynamic. Influencing factors include:
- Ambient temperature and humidity (the more you sweat, the more water you need)
- Physical activity (see the sweat comment above)
- Dietary intake (high-salt or high-protein diets can increase water requirements while high fruit and vegetable intake can decrease requirements)
- Health conditions (such as kidney disease, heart failure, or certain medications)
General Recommendations:
- For healthy adults, the U.S. National Academies of Sciences suggests about 2.7 liters (91 oz) per day for women and 3.7 liters (125 oz) per day for men. This is from all fluids and foods combined (not just water intake).
- For purely water intake – the average adult can aim for 2 to 3.5 liters per day (about 64-100 oz)
- The numbers above come from subtracting about 20% of your fluid intake needs because many get that percentage from food (especially fruits and vegetables).
- Urine color is a practical biomarker – you want to aim for pale yellow, not completely clear or dark yellow/amber.
Some notes:
- Individuals with heart, kidney, or liver conditions should always follow hydration recommendations specific to their clinical care team
- Urine color may be altered by supplements/medications and is therefore not a good marker for all
Practical Ways to Build a Hydration Habit
I can’t emphasize this enough, creating genuine habits is KEY for sustainable lifestyle changes. I’m talking about doing stuff without even having to think about it because it’s so ingrained in your routine. We all have a lot going on – and the easiest way to be healthy, is by prioritizing this.
- Prepare the night before: Have a bottle ready at night and start your morning with a glass of water before coffee or breakfast.
- Keep water visible and accessible: A reusable bottle at your desk, bedside, or bag acts as a visual cue.
- Flavor strategically: Adding citrus slices, cucumber, mint, or berries can make hydration more appealing without added sugars.
- Pair water with daily habits: Already have habits in place? Pair drinking water with one you already have. Examples include drinking water before brushing teeth, while you prepare breakfast/coffee, or on the drive to work.
For those who struggle with water intake alone, including hydrating foods such as cucumbers, watermelon, oranges, and soups can contribute meaningfully to total hydration.
Final Thoughts
Proper hydration is fundamental—not just for athletic performance or skin health, but for systemic health across organ systems. It’s a behavior that supports your body’s resilience and daily function.
If you’re focusing on your health and don’t know where to start, hydration is an excellent first step—both simple and scientifically sound.
