How to Use the EUHHAC Tool to Promote Healthy Drinking Habits

This article is based on the EUHHAC Tool, developed by the European Federation of the Associations of Dietitians (EFAD) in collaboration with Danone Nutricia Research. The tool was designed to help dietitians turn hydration science into practical advice for clients and the general public.

Did you know that 1 in 2 people worldwide don’t drink enough water each day? Staying hydrated is not just about avoiding thirst—it’s directly tied to your mood, brain function, kidney health, digestion, and overall well-being. That’s why EFAD and Danone Nutricia Research developed the European Healthy Hydration Campaign (EUHHAC) Tool: to translate science into action and support dietitians and individuals alike.

Let’s break down how you can use this tool to boost your hydration awareness and empower healthier daily habits.

Step 1: Understand Hydration’s True Impact

Water plays a vital role in:

• Cognition and mental focus

• Mood regulation

• Kidney function and preventing urinary tract infections

• Supporting your gut microbiota

It’s also important to watch out for sugary drinks! The tool shows that typical beverages like soda, flavored milk, and fruit juice can contain up to 3g of sugar per 100ml—contributing to weight gain and chronic disease risk. The WHO recommends keeping free sugars under 10% of your daily energy intake.

 Step 2: Spot the Signs of Dehydration

The guide details early symptoms you might be ignoring:

• Dry mouth and skin

• Fatigue or headaches

• Dark-colored urine

• Dizziness or irritability

In severe cases, dehydration can lead to low blood pressure, rapid heartbeat, and even delirium. Recognizing the signs early helps you act before things get serious.

Step 3: Use Urine Color to Monitor Hydration

Yes, your pee is trying to tell you something! The EUHHAC urine color chart is a simple and effective way to check your hydration status at home.

• Pale yellow = well hydrated

• Dark orange or strong yellow = drink more water, ASAP!

Step 4: Assess Your Fluid Intake

Choose one of the 3 methods:

• Fluid Record (3-7 days) – for detailed tracking

• 24-hour Recall – for quicker insights

• Drink List + Visuals – great for quick consults or self-reflection

The printable drink visuals (cups, glasses, mugs) are also super helpful for clients!

Step 5: Personalize Recommendations

Fluid needs vary by:

• Age & gender

• Pregnancy & breastfeeding

• Physical activity

• Environmental temperature

Adults generally need 2–2.5L of fluids per day, and even more during hot weather or intense activity. The tool offers clear guidelines based on EFSA recommendations.

 Step 6: Consultation & Follow-Up

The tool includes tips for dietitians on how to:

• Ask the right questions during consultations

• Identify barriers (like forgetting to drink or disliking water)

• Offer realistic solutions, like adding fruit slices to water or creating a drink reminder routine 

 Why This Tool Is a Game-Changer

Whether you’re a healthcare provider or just someone trying to stay healthy, this tool simplifies hydration science into doable daily practices. As a dietitian, I use it in my clinic to help patients make small changes with big impacts.
