5 June 2025

Hello Ziddis! Have you ever felt hungry at odd hours or even when you have had your meal? As strange as it might feel, we give in to the hunger and grab ourselves a snack. But hold on! It is not really the hunger. It is symptoms of dehydration calling out to you. This is an often misinterpreted sign of our body’s call for help that we end up ignoring because we don’t know how to differentiate! Let us understand it better.

Hunger vs Dehydration

It is common to get a sudden urge to grab a snack, only to wonder if it’s because you are actually hungry or bored! But well, there is a secret third reason too! The signals for hunger and thirst often overlap in our brain, making it difficult to tell them apart. While hunger is our body’s ask for nutrition and nourishment to fuel itself, dehydration is like an alarm asking for fluids, but the symptoms of both and strangely similar.

Symptoms of Dehydration That Mimic Hunger

Dehydration is often the most misunderstood sign of our body. It doesn’t just make you feel thirsty, it also tricks your body into thinking it needs more food and is hungry. Here are some signs that are common to dehydration and hunger:

Mild headache
Fatigue
Growling stomach
Feeling of an empty stomach
Irritability
Low mood
“Hangry” feeling
Lightheadedness or feeling dizzy
Sudden food cravings, mainly for salty or sugary snacks

It is normal to misinterpret these signs, as they sound more like hunger and less like dehydration. But it is not food, it is water that your body needs at this moment. There could be instances where this could be a hunger sign, but it is always a great idea to have a glass of water first to understand the signs of your body better.

Tips to Distinguish Between Hunger and Thirst

Next time you spot these signs and feel like grabbing yourself a snack, try a quick self-check!

Drink a glass of water first and observe if the feeling goes away in 10 minutes. If so, it was likely thirst
Check the time of your last meal. If it is more than 3 to 4 hours, then this could be a call for hunger
Notice what you are craving. If it is some salty or juicy food specifically, it is most likely just dehydration because real hunger is more flexible and not bound by your taste buds and cravings.
Assess your energy levels. If you feel tired, sluggish or foggy, that must be hunger fatigue with low blood sugar levels.

Signs of Dehydration That Lead to Cravings

When your body is low on fluids, it can create cravings to trick you into getting some hydration from food. Think of it as spotting an oasis in a desert. There are signs of dehydration that eventually lead to a craving mindset. Let’s check those out!

Unusual cravings for salty snacks
Wanting to have more soda, juices or shakes
Muscle cramps
Headaches
Dry mouth or lips
Dark yellow urine
Dry skin or lack of sweat
Irritability
Hanger pangs

Your body needs water more often than not to regulate everything from digestion to body temperature control, so if you are not hydrated, these cravings can intensify and push you towards snacking on food with water content. You don’t need calories, you just need moisture!

Takeaway

So next time you have an intense craving or stomach growling moment, check on yourself before reaching out for that snack. Ask yourself, “Is this really hunger or am I just dehydrated?” A glass of water could be all you need to curb these untimely and unnecessary cravings. Help your body stay balanced by carrying a water bottle around, especially in warmer months or during your most active hours. You can start having some creatine too if you work out to balance the hydration levels for your muscles, and if it is just one of those warmer months, you can add some electrolytes to your water to get more benefits out of it.
