5 Early Signs You’re Dehydrated

Why hydration isn't just about water?

1. Headaches

When your body lacks fluids, the volume of blood plasma decreases — reducing oxygen flow to the brain. That can cause headaches, especially in your temples or the back of your head.

Studies show that dehydration can trigger headaches similar to migraines — and rehydrating with electrolytes often reduces the symptoms².*

2. Fatigue (Even After Resting)

If you’re feeling sluggish despite sleeping well, dehydration could be the reason. It can lower blood pressure and oxygen delivery, leaving your cells running on low power.

Fun fact: Even mild dehydration reduces cardiac output and increases your resting heart rate³.

3. Trouble Focusing

Even slight dehydration — as little as 1% of body weight — can impair attention, memory, and mood.

A 2012 study from The Journal of Nutrition found that dehydrated women had slower reaction times and increased mental fatigue⁴.

4. Muscle Cramps and Twitching

Cramping after a workout or in the heat? It’s not just fatigue — it’s often a lack of electrolytes. Sodium, potassium, and especially magnesium are essential for normal nerve and muscle function.

Magnesium helps regulate muscle contractions and nerve signals — and a deficiency can cause random twitches or tightness⁵.

5. Dry Skin and Lips

If your lips are cracking and your skin feels tight or itchy, your body might be rationing fluids. Less saliva, less sweat = visible signs of dehydration.

Studies suggest that skin hydration reflects overall hydration status — especially in hot or dry climates⁶.*

How to rehydrate effectively

Drinking plain water isn’t always enough — especially if you’re sweating, traveling, or training. Electrolytes help your body absorb and retain water, preventing that “in-one-end-out-the-other” effect.

Recap: Don't wait until you're thirsty

By the time you feel thirsty, dehydration has already started. If you notice fatigue, poor focus, dry lips, or muscle cramps, your body might be missing both water and key minerals.

Hydration = Energy, Clarity, Recovery.  

Start with water, level up with electrolytes.
