While massages are meant to help people feel relaxed, they can cause side effects. In a study conducted by the National Institutes of Health Sciences, it was found that massages can cause muscles soreness, fatigue, headaches and even bruising.
Massages are thought to cause side effects because they release toxins and reduce inflammation in the body. In doing so, these toxins can make a person feel ill until they are flushed out of the system.
For many people, the positive effects outweigh the negative feelings. Massages have been shown to help improve mood and overall well-being and have even been linked to improving respiratory and digestive function. Massages are often recommended for patients with cancer or pregnant women as a treatment option to reduce negative symptoms.
