A process for subjecting a surface of the skin or of the hair to an abrasive and/or stimulating action, including projecting onto the surface a flow of at least one composition including a vector liquid and solid particles, the flow being generated from the collision of at least two jets generated by at least two nozzles of a dispensing device, the nozzles oriented such that their jets encounter one another, and at least one nozzle being supplied with a pressure of at least 4 bar and with a vector-liquid flow rate of less than or equal to 10 L/min.

A system and a method for applying a gradient of external compressive forces on the body of a person, in a manner analogous to how water exerts hydrostatic forces on the body of person immersed in water. The system may be a chair or a suit, comprising at least one of the following: one compression unit holding fluid around the person to exert a gradient of hydrostatic forces, at least one rigid or semi-rigid frame or a shell supporting the body and the compression units to support the pressure and off-loaded weight of the person and transfer the weight to an external support such as floor. Additionally, the system may contain additional means to reduce the frictional forces on the body surface and between various moving parts, and a means to modify pressure on the body of the person. The system and method is applicable for effecting physiological changes in the body such as increased diuresis and/or amniotic fluid levels, treat preeclampsia in pregnant women, reduce hypertension, shift fluids from interstitial space into intravascular compartment, increase venous return from lower extremities, reduce sympathetic tone and total peripheral resistance, reduce work load on the heart, reduce motion sickness and the like.

The disclosure describes a system and a method for applying a gradient of external compressive forces on the body of a person, in a manner analogous to how water exerts hydrostatic forces on the body of a person immersed in water. According to an embodiment, the system may be a chair or a suit and is applicable for effecting physiological changes in the body such as increased diuresis and/or amniotic fluid levels, preeclampsia treatment in pregnant women, reduced hypertension, shift in fluids from interstitial space into intravascular compartment, increased venous return from lower extremities, reduced sympathetic tone and total peripheral resistance, reduced work load on the heart, reduced motion sickness, and the like.
