Electrolytes & How Your Body Feels
A simple guide to what your tissues might be telling you about your electrolyte balance. You don't need blood tests to start paying attention — your tissues, energy, and recovery often give you early clues, dietary adjustments are the gold standard for managing your electrolytes.
Sodium — puffy outside, dry inside
When sodium is high, water shifts outside your cells. You can feel both "puffy" and "dehydrated" at the same time.
How it can feel
- Puffy fingers or face, especially in the morning
- Thirst that doesn't go away easily
- Heavy legs or arms during movement
- Headaches after salty meals or snacks
Tissue feel
- Skin feels slightly spongy or boggy
- Muscles feel full but not strong
- Fascia feels sticky or slow to glide
Potassium — flat battery tissues
Potassium pulls water into your cells and helps muscles fire smoothly. Low potassium often feels like a "flat battery".
How it can feel
- Weakness or low power despite training
- Twitching or cramping during or after exercise
- "Tired but wired" — fatigued but unable to fully relax
- Feeling dehydrated even when drinking enough
Tissue feel
- Muscles feel dry, stringy, or ropey
- Stretching feels sharp instead of smooth
- Fascia feels sticky or resistant between layers
Magnesium — tight but tired
Magnesium helps muscles and the nervous system relax. Low levels often feel like tension that won't switch off.
How it can feel
- Persistent tightness in neck, shoulders, or calves
- Restless legs at night
- Trouble relaxing into sleep
- Feeling on edge or more sensitive to stress
Tissue feel
- Muscles feel tight but not truly strong
- Trigger points that keep coming back
- Fascia feels rigid or guarded under pressure
Calcium — snappy and reactive
Calcium drives muscle contraction. When calcium handling is off, tissues can feel jumpy or "snappy".
How it can feel
- Sudden cramps, especially with movement or stretching
- Tingling around the mouth or fingertips
- Muscles that "jump" when you stretch them
Tissue feel
- Muscles feel spring-loaded and quick to guard
- Fascia tightens quickly when you move into a stretch
Chloride — washed out
Chloride works with sodium to help manage fluid balance and blood pressure.
How it can feel
- Lightheaded when standing up
- Feeling washed out or flat
- Poor tolerance to heat or hot environments
Tissue feel
- Muscles feel weak rather than tight
- Fascia feels thin or under-hydrated
Phosphate — low power output
Phosphate is essential for energy (ATP) production.
How it can feel
- Heavy legs early in a session
- Struggling to produce power, even when motivated
- Breathlessness that feels out of proportion to effort
Tissue feel
- Muscles feel soft or underpowered
- Fascia feels dull rather than springy
Bicarbonate — buffering acid load
Bicarbonate helps your body buffer acid build-up during higher intensity work.
How it can feel
- Burning legs early in exercise
- Feeling "acidic" or inflamed after hard sessions
- Breathlessness during high-intensity efforts
Tissue feel
- Muscles feel hot or irritated under load
- Fascia feels reactive when pressed or stretched
Using This Guide
This isn't a diagnostic tool, and it doesn't replace medical advice. It's a way to pay attention to patterns in how your body feels over time.
Across a week, notice:
- Tissue feel: dry, puffy, tight, weak, reactive?
- Movement: smooth, stiff, twitchy, heavy?
- Recovery: fast, slow, or incomplete?
- Load tolerance: stable, fragile, or inconsistent?
If symptoms are persistent, worsening, or worrying, speak with a qualified health professional. From there, we can work together on load, recovery, and tissue quality in the clinic.
