What a nice and innovative idea! Although I don’t know the specific application method, I feel that applying physical factors to health care would be a good choice.
First of all, harmonious music can mobilize people's emotions and promote blood circulation. It is widely used in square dancing, yoga, and health exercises. For people suffering from insomnia and anxiety, quiet and soft music can also relax the mood and promote sleep.
Secondly, the physical applications of light are very wide. People nowadays focus on whitening, but ignore the positive effects of ultraviolet rays on the human body. Some optical technologies have already been applied to clinical medicine, and I believe they will also be applied to health care in the near future. This requires certain research results as theoretical support. For example, will light be effective for people who often work three shifts?
Electricity can be applied to click massage. It can also promote blood circulation and help muscle exercise. Human nerve reflex is essentially a bioelectrical reflex.
