I'll share with you a huge benefit of using vibration massagers most people don't consider. There have been a lot of clinical trials where massages have helped with health issues such as improving sleeping, improving psychological states and even reducing blood pressure. We have a table summary in our article Massage for health and wellness .
The main problem though is to get these great results they needed to use very regular massages such as weekly or three times a week. If using professional therapists this would be beyond most people, but is something you could easily do using self massage with a vibration massager.
