Massaging apparatus and massage method

A massage method comprising:

• obtaining detection results, outputted by skin condition sensors, indicating retention levels of lymph under a part of a skin of a user, a sheet including an area having subareas, the sheet being attachable to the skin including the part, the area corresponding to the part, and the skin condition sensors being included in the area;
• applying an operation to discharge the lymph using piezoelectric elements included in the subareas;
• determining the operation, based on the detection results and first information stored in a memory;
• and
• causing the piezoelectric elements to perform the operation,
• wherein the piezoelectric elements include a first piezoelectric element, a second piezoelectric element, and a third piezoelectric element,
• wherein the first information includes information indicating that the first piezoelectric element is activated during a first period, the second piezoelectric element is activated during a second period, and the third piezoelectric element is activated during a third period,
• wherein the subareas includes a first subarea including the first piezoelectric element, a second subarea including the second piezoelectric element, and a third subarea including the third piezoelectric element,
• wherein the second subarea is provided between the first subarea and the third subarea, the first subarea touches the second subarea, the third subarea touches the second subarea, the first subarea and the second subarea having no overlap, the first subarea and the third subarea having no overlap, and the second subarea and the third subarea having no overlap,
• wherein the lymph is adapted to be discharged from a portion under the first subarea to a portion under the third subarea through a portion under the second subarea,
• wherein the first period is a continuous time, the second period is a continuous time, and the third period is a continuous time,
• wherein a start time of the first period precedes a start time of the second period, a start time of the second period precedes a start time of the third period, an end time of the first period precedes an end time of the second period, and an end time of the second period precedes an end time of the third period,
• wherein the sheet has a three-dimensional shape and configured to cover an entire face of the user except for openings for eyes and nostrils of the user,
• wherein the sheet has elasticity and flexibility,
• wherein the sheet is configured to maintain a contact with a skin surface of the entire face except for the openings for the eyes and the nostrils of the user due to a surface tension of the sheet, and
• wherein a massage pattern of the piezoelectric elements is determined based on an outside temperature and an outside humidity.
