Treatise
Objective To investigate and study the application and evaluation of natural convalescent factors in the rehabilitation institutions of health resorts in China,in order to provide scientific basis for the scientific planning,rational development,utilization,and protection of medical natural resources in the rehabilitation institutions of health resorts.Methods The random cluster sampling method was adopted to conduct a survey on 70 rehabilitation institutions across the country from May to August 2024.68 valid institution samples were collected.SPSS AU 27.0 software was used to analyze and evaluate the nature of different natural convalescent factors and the application and suitability of medical natural resources.Results The evaluation of 34 sea bathing beaches showed that 70.6% had clear water,while 29.4% had turbid water;58.8% were safe without any danger,and 38.3% had a slight danger;58.8% had slightly turbid seawater color;73.5% of the 1.5-meter-deep water area (distance from the coastline) was >30.5 meters;73.5% of the beaches had good conditions.The evaluation of 30 sunbathing beaches showed that 80.0% of the beaches had an area per person >4.5 m2,60.0% of the beaches free from intense sun exposure throughout the year were >80%,76.7% of the beaches had backland cover and trees,and 86.7% of the beaches had waste and natural hazard substances.The evaluation of 23 mineral water resources showed that 47.8% of the mineral water had an outlet temperature ≥50 ℃ and <70 ℃;52.1% contained two or more trace elements,gases,and radioactive elements,and had a mineralization degree ≥1 g/L;95.7% of the mineral water met the GB 8537 standard,and only one health resort did not meet the sewage comprehensive discharge standard;56.6% of the mineral water had daily hygiene routine tests and had full-time testing personnel;52.1% of the mineral water was applied in medical fields.The evaluation of 9 mud therapy resources showed 44.4% of the mineral salts was ≤10%,and 55.6% had temperatures ≥42 ℃ and <55 ℃;44.5% of the application methods (full-body immersion,local wrapping,mud paste,adding Chinese medicine,electricity,wax,etc.) involved more than 3 types;Only 2 of the health resorts failed to meet the mud quality and microbial indicators standards;44.4% of the health resorts were used for medical and health care.The evaluation of 29 forest bathing resources showed 89.6% located more than 20 km away from industrial areas or urban noisy zones,being mountain forests with convenient transportation,fresh air and no noise;82.8% of the forest land had trails,with more than 2 types of design,and the forest was comfortable for walking and activities;62.1% had an area of over 670 hectares;93.1% had a vegetation quantity that maintained green landscapes and seasonal changes;79.3% had certain tree species that could volatilize a large number of aromatic substances.Conclusion It is necessary to regularly assess the quantity,quality,distribution of natural convalescent factors in the health resorts,and analyse its convalescent value,strictly follow the ecological environment safety and health care parameters.Relying on policy-driven and international certification standards,it is to promote the scientific application and sustainable development of natural convalescent factors in the rehabilitation institutions of health resorts,and contribute to Healthy China.
