These types of hot flashes that you describe are often associated with hypothyroidism; hot flashes are commonly characterized by intense heat, sweating
in the upper part of the body, along with an accelerated heart rate. The duration of a hot flash can vary between individuals and usually begins with a sensation of heat in the face or chest that spreads through body.
The hot flashes occur due to hormonal imbalances associated with thyroid issues that can alter the body’s ability to regulate temperature effectively.
Thyroid hormones also affect parts of the brain that help regulate mood and depression is often characteristic of hypothyroidism. There is a wealth of research published suggesting that thyroid patients have a higher incidence of depression and anxiety
disorders than the average general public. You are correct in identifying the feeling as ‘physical’ as hormone imbalances are exactly that.
I would recommend speaking to your physician regarding the treatment of your thyroid in order to determine your thyroxine levels and the effectiveness of any treatment. It is important that the link between your depression and thyroid problem is identified and that any medication prescribed is actually effective.
As I am sure you are already aware a healthy diet and regular exercise will also have a positive effect on your mood.
