How do different massage functions of the KY1081 massager work together to enhance the effect? Is there any scientific basis for this?

Air pressure simulates the kneading of professional masseurs, quickly relaxing muscle knots; red light (630nm wavelength) penetrates the epidermis by 3-5mm, promoting collagen production and inflammation reduction; heat therapy dilates blood vessels and accelerates the excretion of metabolic waste; vibration deeply stimulates the fascia layer. The combination of these four functions has been clinically tested to increase relaxation efficiency by 40% compared to a single function (data from a third-party testing institution).
