What Is HRV and Why Should You Care?
Your body’s hidden signal for health, recovery, and resilience
Imagine two animals in the wild:
A cheetah, fast and deadly — but resting calmly under a tree.
A gazelle, hyper-alert, muscles tense, scanning for danger.
Both are strong in their own ways.
But only one is recovering. Only one is adaptable.
That difference? It’s what scientists call Heart Rate Variability, or HRV.
💓 So… What Is HRV?
HRV stands for Heart Rate Variability — the variation in time between each heartbeat.
If your heart beats 60 times per minute, it’s not beating once every second.
Instead, there might be 0.9 seconds between one beat, then 1.1 seconds before the next.
That variability is a good thing.
In fact, it’s a key sign that your nervous system is flexible, adaptable, and ready for anything.
⚖️ Why HRV Matters for Your Health
HRV reflects the balance between two sides of your autonomic nervous system:
Sympathetic (fight-or-flight) — gas pedal
Parasympathetic (rest and digest) — brake pedal
A high HRV means your body can easily shift between stress and recovery.
A low HRV means your system is stuck — often in survival mode — and has trouble adapting.
🚨 What Low HRV Can Feel Like
If your HRV is consistently low, you might notice:
Trouble recovering from workouts
Poor sleep, even when you're “in bed”
Frequent colds, illnesses, or flare-ups
Chronic pain or lingering soreness
Feeling exhausted but wired
Sound familiar? You’re not alone.
🧘♀️ The Cheetah Is Calm. You Can Be Too.
That cheetah under the tree isn’t weak — it’s strategically recovering.
At SB Physio, we believe your health isn’t just about fixing pain. It’s about building resilience — the ability to move, heal, and perform no matter what life throws your way.
That’s why we teach movement, breath, and recovery in everything we do — because these are the tools that raise HRV and shift your body out of chronic stress.
