The short answer is Yes!
The 2018 research, "Therapeutic Role of Yoga in Type 2 Diabetes", reviewed the numerous benefits for people living with this chronic condition. They found that the many perks of yoga worked by affecting psychology (thoughts and emotions), neurology (brain and nervous system), immunity, and hormones.
If you are a Type2 reading this and thinking "I cant go to a yoga class; I'm not flexible; I'm not a pretzel!", it is worth knowing that yoga is not just postures. Yoga can include mindfulness, proper breathing, gentle mobility and stretching movements, intentional visualisation, relaxation, and making sounds (even humming produces a beneficial change to the nervous system and blood pressure!). You just seek out the right teacher for you; they will be teaching a gentle class (called gentle, yin, or restorative), offer purely breathing/mindfulness classes, or when you contact them to ask, they will will be able to offer you something appropriate or refer you elsewhere.
Here are the benefits of yoga for people living with T2 diabetes (and those diagnosed with 'pre-diabetes').
The image below is from the published research and shows even more benefits, including better mood :)
