4. Increased sensitivity to heat
Graves’s disease can cause eye problems and sensitivity to the light, but you may also find that you feel greater sensitivity to heat as well. Since one of the main functions of the thyroid gland is regulation of the metabolism, the way the body deals with heat can be affected by the thyroid. When the thyroid and metabolism are working well, it helps maintain the basal metabolic rate.
Hypothyroidism may cause people to feel overly sensitive to the cold. However, hyperthyroidism caused by conditions such as Graves disease can hinder the body from dealing with heat normally. This heat sensitivity can be dealt with by treating the hormonal issues created by Graves’s disease. However, to keep you comfortable until the symptoms disappear, drink plenty of cold beverages, especially water, stay in the shade and use electric fans to stay cool. Carry a spray bottle and cool off by spraying your face with cold water.
