The aim of the project implemented by the Health Sanatorium “At the Tężnia” is to adapt its infrastructure to the needs of the elderly and with disabilities. Reduce the entire coastline of the reconstructed rehabilitation pool by 20 cm, which will ensure greater safety for elderly and disabled people during treatments. The construction of a new swimming pool will make it possible for more patients of the Health Sanatorium “At the Rainbow” to benefit from treatment of cardiovascular, musculoskeletal, musculoskeletal and respiratory diseases. This investment will allow the use of medical treatments for a large group of people. The construction of a new water drinker, in view of the positive effects on immune and immune systems, will improve the effective treatment of older people and with disabilities and contribute to the return of people with disabilities to the labour market.
