Can Blue Light Damage The Thyroid Gland?

Some studies suggest a link between exposure to blue light at night, such as working the night shift, to thyroid, diabetes, heart disease, and obesity. Excessive exposure to blue light in night results in disruption in melatonin hormones. This can result in bad sleep. Many studies are proving now that direct exposure of blue light can also affect the conversion of T4 to T3 which is the active hormone.
