One reason for our ears to turn red is that at times our sympathetic nervous system kicks in on its own and causes our bodies to release adrenalin and noradrenalin. Noradrenalin is the chemical responsible for relaxing the smooth muscle in the walls of the blood vessels. When the smooth muscle in the blood vessels relaxes the diameter of the vessel increases and the volume of blood passing through the blood vessel also increases. This is referred to as vasodilatation. When this happens the skin feels warm and may have a pink or red colour.
This usually happens when we feel nervous or stressed and is part of the "fight or flight" mechanism, even though the only "threat" may be social. However, in some people the sympathetic nervous sytem is overactive. This can be caused by inherited genes. We have no conscious control over the sympathetic nervous system so it kicks in without our decision to be "embarassed."
The sympathetic nervous system is part of the autonomic nervous system (ANS), the control system for the body that keeps all our internal organs functioning properly. These maintenance activities are primarily performed without conscious control or sensation, The nerves report directly back to the brain stem and can keep functioning even when the conscious mind is no longer working, hence the ability of some brain-dead patients to continue to breathe. The ANS controls heart rate, digestion, respiration rate, salivation, perspiration, diameter of the pupils, micturition (the discharge of urine), blushing, sweating, and erection.
Uncontrollable blushing is also called Idiopathic Craniofacial Erythema. Treatments include anti-anxiety medications, clonidine (inhibits the action of noradrenaline), beta-blockers, hypnosis, psychotherapy, and as a last resort, surgery.
Sweating is also controlled by the ANS and the cause of hyperhidrosis has been traced to overactivity in the sympathetic component, as opposed to the parasympathetic component, of the ANS.
There are other causes of flushing and sweating. Some people sweat excessively because they are obese or they may be suffering from an overactive thyroid gland. Menopause is another obvious cause of both flushing and sweating. Flushing and sweating can also be prominent physical symptoms associated with the mental health condition known as social phobia. Flushing is almost never due to a serious medical condition with one notable exception, which is the rare condition known as carcinoid syndrome.
Medication may also give rise to flushing. The list of possible culprits includes various hormonal treatments for prostate cancer; gylceryl trinitrate, which is used in the treatment of angina; tamoxifen, which is used in the treatment of breast cancer; raloxifene, which is used for treating osteoporosis; calcium channel blockers, which are used to treat high blood pressure and chlorpropamide, which is used for treating Diabetes and can cause flushing if the person takes alcohol concurrently.
