Resting Pulse Reading

Your resting heart rate is a simple window into your nervous-system tone. Sit quietly for a minute first, then measure.

How to read your pulse — two ways:

By hand (radial): Turn one palm up. Place the index & middle finger of your other hand on the thumb-side of the wrist, just below the crease. Press gently until you feel the beat. (You can also use the carotid pulse on the side of the neck.)
Pulse oximeter: Clip it on your fingertip, stay still, and read the PR / heart-rate number (beats per minute) once it settles.

Using your hand? Press Start Pulse Timer — you get a 2-second "get ready" pause, then count the beats for 15 seconds. We multiply by 4 to get your beats-per-minute.

Press start, wait for "GO", then count every beat until the timer stops.

Breath-Hold Test (Control Pause / Kumbhaka)

This measures your body's CO₂ tolerance and the calm-tone of your nervous system — a core Siddha and pranayama marker.

How to do the Control Pause:

Breathe normally. Take a normal, small breath in, then a normal breath out.
After the exhale, pinch your nose and press Start.
Press Stop at the first natural urge to breathe (the first swallow or tightening) — not when you are gasping.

Safety first: This is a gentle first-urge measure, never a forced maximum hold. Do not strain. Skip or stop this test if you are pregnant, or have heart, blood-pressure, respiratory or fainting conditions. Never do breath-holds in or near water.

Breathing Rhythm Optional

Extra breath-capacity markers. These refine your reading but are not required — leave blank to skip.

Slow inhale length

Slow exhale length

Tip: press the button as you begin, and again when you finish that single slow inhale (or exhale). A calm, even rhythm usually shows a longer, smoother exhale than inhale.

Your Body Constitution

Your dominant Siddha constitution (Mukkuttram) shapes which foods and herbs suit you best.

You need at least your constitution. Pulse and breath-hold make the report far more personal.
