Both body massage and bodily exercise of the musculature induce various physical pressures on the venous blood vessels throughout the circulatory system. The human body simultaneously exploits these induced pressures and protects the circulation of the blood using one-way flow valves in the blood vessels which close each time the blood vessel is sufficiently compressed, ensuring that all such pressures contribute to blood-flow in the same uniform direction as the heart's pumping action. Although a person can intentionally pump his or her musculature at various points of the body to take a modicum of load off the heart muscles and attain a sense of well-being similar to that resulting from massage, technology with wearable electronics can now achieve similar but more sustained results with greater efficacy even when the garment wearer is otherwise engaged in other activities. A garment into which this technology is integrated is here dubbed a Valentine garment.

For medical purposes, such technology can benefit cardiac care patients, geriatric patients, obesity patients, cancer patients, and sufferers of mental health conditions. For non-medical purposes, the same technology can benefit ordinary health buffs, athletes, weight loss program participants, long-distance commuters, and even exercise-averse individuals who nevertheless recognize that the technology can lower especially their unique health risks.

Integrated into the Valentine garments, small electrodes on skin-contact pads (called PULSATILEs) under the control of parallel processors in a central processing unit stimulate muscles to contract in sustained rhythmic pulsations that work hand-in-glove with the natural circulatory system without calling undue attention to their actions for the wearer, particularly after the wearer has grown accustomed to them. The device simply electrically elicits action potentials in nerve fibers within the muscles, triggering muscular contractions. For the medical variant of the device, the device will also monitor, via skin-contact electrodes, electrophysiological signals. A garment of this kind can be operated at gentler, more intense, or alternating back and forth between upper and lower intensity levels, as well as focus wave cascades in particular regions of the body for medical, psychiatric, or other purposes.

Non-invasive pulsations of the device can be set by user, physician, or manufacturer to:

• Pulsate in proportion to stress as monitored by cell phone app;
• Pulsate in synch with walking, music, or exercise;
• Pulsate alternately between intense and gentle;

This device is wearable and can be combined with clothes fashions and worn underneath outer garments. This technology can readily be integrated with VR tech and virtual social media. Within IoT this device can fit into the Internet of Wearable Things (IoWT).

One of the most interesting case uses is for wearers who either drive long distances or are passengers in a vehicle during long drives. Studies of such individuals show the hazards of long, sedentary travel on the cardiovascular system. The Valentine garments can offset these hazards and reduce the incidence of unfavorable health outcomes including stroke and myocardial infarction.
