Yoga is a type of exercise that reduces an individual's stress levels. There is circumstantial evidence that increased stress can lead to thyroid problems in the human body. A study in 2017 found out that yoga reduces stress levels and improves the well-being of a person. Certain yoga asanas are considered to balance out hyperthyroidism and hypothyroidism.
A small study was conducted in 2014, and a conclusion was drawn that yoga leads to improved thyroid functions.
Yet another study conducted in the year 2016 proved that six months of yoga leads to improved cholesterol levels and TSH (Thyroid Stimulating Hormones) levels. Hence, the need for thyroid replacement therapy for women suffering from hypothyroidism reduced considerably.
