Cinnamon bark is made from the bark of trees in the Cinnamomum family and is used in a variety of applications, including cooking and baking, traditional medicine, and as a natural fragrance in cosmetics and personal care products. Cinnamon bark has been used for centuries for its potential health benefits and is believed to have several potential benefits, including blood sugar control, heart health, brain function, and antioxidant properties.
Cinnamon bark can be beneficial for sleep, and studies have suggested that it may have a positive effect on sleep quality and duration.
Studies have found that people who took a cinnamon supplement experienced a significant improvement in sleep quality, as measured by the Pittsburgh Sleep Quality Index. Another study found that cinnamon improved sleep quality and duration in people with sleep disorders, including insomnia.
