तणाव ही साठवलेली जैविक ऊर्जा आहे — व्यायाम ती बाहेर टाकतो

Even reading a stressful email can trigger billions of neurons in your brain to fire electrical signals. The human brain contains about 86 billion neurons. Each uses tiny electrical voltages of around 70 millivolts. Together, these signals create measurable electrical activity that scientists can observe using brain scans.

When stress arrives, your body prepares for action: heart rate increases, muscles tighten, breathing changes, glucose enters the blood, and muscles store extra energy molecules called ATP — the fuel for every muscle movement.

The problem is this: your body prepares to move, but modern stress usually keeps you sitting still. You stay in a chair, car, or meeting while the stress chemicals remain active. The prepared energy does not get fully used. Your jaw stays tight. Shoulders become stiff. Chest feels heavy. Mind keeps racing. Scientists call this a "chronic stress state."

When stress continues for weeks or months, neurons become overactive and "leaky." They become too sensitive and struggle to fully relax. This is linked with anxiety, burnout, poor sleep, panic feelings, and constant tension.

This is why simply lying down or watching television does not always remove stress. Rest can quiet the mind temporarily, but the body still holds much of the unused stress energy.

Exercise changes this physically. When you walk, run, cycle, stretch, or lift weights, muscles finally use the stored ATP, glucose gets burned, adrenaline decreases, breathing deepens — and the nervous system receives an important signal: "The danger is over. We survived."

Stress is not only an emotion — it is stored biological energy. Movement gives the body a safe and natural way to release it.
