- An Endocrine disorder (which is often missed) or a brain injury or disorder, or the process of dying in which all organ function ceases, related to specific internal mechanisms of the human body. Including those listed below. External sources are numerous.
- Temperature is regulated by the thermoregulatory mechanism by nervous system.The Hypothalamus in our brain is responsible for the temperature and thirst drive.Whenever the the person is exposed to severe cold,the hypothalamus in the central nervous system is stimulated and it leads to constriction of blood vessels to maintain the body in optimal temperature and prevent the excessive loss of heat. Whenever these mechanism is disturbed by head injuries, the person may have the chance of getting cold stroke and paralysis of body.
- As our body temperature increases ,to control it skin excretes sweat so that temperature controls. A reason for low body temperature can be an under-active thyroid. While we cite 98.6F as "normal" body temperature (taken orally), the truth is that normal body temperature varies from one healthy person to another, and temperatures as low as 98.0F are not uncommon. The second most common cause is reduced surface temperature resulting in hypothermia -- the patient has recently been exposed to a cold environment. At rest, an uninsulated patient in temperatures as high as 60F (roughly) in air may show reduced body temperature. Hypothyroidism and other metabolic disorders may also manifest as chronic low body temperature.
- My wife and I visited the doctor yesterday. She clocked in at 97.4F. I asked the doc about it -- he said no big deal. It's not a pathology; only a personal variance.
- The most common cause of (temporary) hypothermia is submersion in cold water. Heat is lost much faster in water than in air.
- The next most common cause of (temporary) hypothermia is extremely cold air. Heat is lost both through the skin and through the lungs.
Answer: I have suffered for years feeling cold all the time and having a low body temperature. That's normal for me but what my Endocrinologist did find out was I had an underactive thyroid issue. So I am on a very small dosage of levothyroxine which seems to keep me from always feeling so cold and has regulated my thyroid levels. My body temp is still low because that's just the way it is, but the medication has helpd me overall .
