If you find it’s always difficult to drag yourself out of bed for that 5 AM session at the gym, it may not be that you’re lazy. Having a hard time waking up, especially if you have gotten 7-8 hours of sleep is a typical symptom of an under-active thyroid gland. Other signs are: feeling cold all of the time or having cold hands and feet, foggy thinking, as well as dry skin especially on the heels and/or elbows. The most common complaint I hear is putting weight on easily and then having a great deal of trouble taking it off despite hours of cardio and dieting.
