A: The application of localized heat therapy stimulates blood circulation across sore or tense areas, which helps dilate blood vessels and relax target uterine or skeletal muscles. This natural, drug-free dilation mitigates throbbing period cramps, joint stiffness, and chronic low back strain effectively. Q: What are the core safety instructions for filling a rubber hot water bag? A: Always allow boiling water to cool down slightly before pouring, and never fill the bottle past two-thirds of its maximum load capacity. Gently squeeze out residual air from the upper neck section before securing the anti-leak screw stopper tightly to prevent scaling accidents.
