Spa centers are a kind of clinic, a medical center that offers various treatments and medical massages for human health.
Since the spa is considered a healing holiday, health resort offers facilities such as sauna and Jacuzzi and massages for body healing (such as lymphatic massage, deep tissue massage, massage, sports, etc.).
This "clinic", which incorporates concepts and techniques from the medical world, also incorporates alternative medicine that includes acupuncture among me, aromatherapy oils, etc.
Today there are many people who prefer alternative medicine than the conventional ones, and it is no wonder that they choose to go to a spa center to take care of their bodies. What is more, alternative medicine (as well as the spa) treats the soul, not just the body itself.
In these places you can see the medical aspect of the workshops and treatments offered: Reiki, yoga, shiatsu, Bach flowers, etc. - because through the treatment of our souls the body is physically healed.
In short, the spa is among the entertainment centers that incorporates so much of the world of medicine and is therefore considered a healing holiday.
