This group will consist of 30 post menopausal women, who will receive placebo High power laser acupuncture and paced respiration exercise for 15 minutes /sessions, 3 times/ week for 4 weeks.

Participants will lie supine while receiving high-power laser therapy (1064 nm wavelength, 150 mJ max pulse energy, 6 W average power, 760 mJ/cm² frequency, <150 ms pulse duration). A pulsed waveform (5000 W/cm², 1 W output, 0.2 cm² spot size) will be applied perpendicularly to acupuncture points for 30 s (×3), totaling 15 min/session. Sessions: 3×/week for 4 weeks. Paced respiration exercises will also be performed for 15 min/session over the same period.
