Can Sanfu patches improve sleep quality?
Generally, the Sanfu Patch (Three伏贴) has a certain auxiliary effect on improving sleep quality, but its effectiveness varies from person to person, and sleep problems shouldn't be addressed solely relying on the Sanfu Patch. Detailed analysis is as follows:

For light sleep and frequent waking caused by insufficient yang energy and blocked meridians, the Sanfu Patch can help improve sleep by stimulating acupoints with warming herbs, thereby unblocking meridians, harmonizing qi and blood, and improving overall physical condition. To achieve better results, appropriate acupoints should be selected and the treatment should be followed consistently over a course of time.
If sleep problems are caused by mental stress, emotional anxiety, or other medical conditions, it is difficult to effectively improve sleep with the Sanfu Patch alone. In such cases, additional approaches such as emotional regulation and lifestyle adjustments are necessary. Furthermore, individuals with a heat-prone constitution may experience worsened sleep due to increased internal heat after using the Sanfu Patch, making it unsuitable for improving sleep in these individuals.
In daily life, improving sleep quality requires developing regular sleep habits, avoiding staying up late, and reducing the use of electronic devices before bedtime. Creating a quiet and comfortable sleeping environment, soaking feet before bed, and avoiding overeating or consuming strong tea and coffee before sleep are also helpful. A comprehensive approach to lifestyle and dietary adjustments can significantly enhance sleep quality.
