Researchers have found that practicing yoga twice a week for 75 minutes can help reduce the risk of cancer spreading or returning. In the study published by the American Society of Clinical Oncology 502 cancer survivors (2-60 months post treatment) were randomised to take part in either 2 x 75 minute yoga sessions per week or 2 x 75min standard survivorship health education sessions. After four weeks, serum inflammation markers were analysed which showed significantly lower overall inflammation in the yoga group compared to standard health education group. Inflammation is known to play a key role in the development and progression of cancer, thus targeting inflammation through treatment protocols is important to minimise the risk of cancer spreading or recurring.
Yoga has also been shown to improve sleep quality in cancer survivors experiencing sleep disruption post-treatment. Cancer survivors randomised to standard care plus yoga for four weeks demonstrated greater improvements in sleep quality and daytime dysfunction as well as reduction in use of sleep medication compared with standard care alone group.
There is a growing evidence-base for the prescription of yoga as an adjunct therapy for cancer patients. Current American Society of Clinical Oncology guidelines for the use of integrative medicine in cancer care recommend yoga for helping to reduce anxiety and depression symptoms (15-20% of cancer patients take medication for anxiety and depression), improving quality of life, mood, fatigue and sleep quality.
The yoga intervention developed for these studies combines gentle and restorative yoga incorporating physical postures (asana), breathing (pranayama) and mindfulness exercises (meditation and awareness).
Yoga, as a non-pharmacological intervention, is a safe practice which can be modified for participants’ physical capacity and level of ability, making it highly accessible to cancer survivors.
