Brief Summary
This study investigate the potential impact of low power laser (LPL), an non-invasive physical therapy, on the cardiovascular system by focusing on its effect on heart rate and autonomic tone. Study will recruit healthy volunteers and non-invasively monitor their electrocardiogram and digital pulse in response to LPL. In addition, the potential involvement of autonomic tone will be clarify by topically applying gel (2% lidocaine gel)

Outcome Measures
Primary Outcomes (1)
heart rate
the heart rate before, during, and after low power LASER
Continuous heart rate (HR) recording will start when it is stable after a brief resting (10 min); maintained during stimulation (30 min), and lasted for a period until the HR recovers.
Study Arms (1)
test effect
EXPERIMENTALControl, experiment, and recovery data will be acquired for each volunteer
Interventions
Low power laser with an intensity for pain relieving will be applied to volunteers
