body temperature in fibromyalgia

Body temperature in fibromyalgia, a puzzle that patients suffering from pain of the emergency or fatigue with fibromyalgia and / or chronic fatigue syndrome of myalgic encephalomyelitis. This may be the drops in response to symptoms of fever temperature and at normal temperatures. The explanation for these symptoms the patient has fibromyalgia is called as a broken thermostat and match everything.

Norepinephrine vasoconstriction in fibromyalgia and chronic fatigue syndrome

New Zealand Dr. LO Simpson researcher hypothesis that CFS is a result of “insufficient oxygen availability due to poor capillary circulation. “Simpson assigns capillary flow capillaries are weakened less than usual, and the presence of abnormal red blood cells.


When the body temperature is less than about 37 degrees Celsius, starts mechanisms to retain heat that is already in the body, and other mechanisms to increase the heat generating rates.

One of the first effects is intense vasoconstriction of the vessels in the skin on the entire body. The rear hypothalamus strongly activate sympathetic nerve signals to the blood vessels in the skin and intense vasoconstriction occurs throughout the body.

body heat loss

This vasoconstriction obviously prevents heat conduction internal parts of the body to the skin. Therefore, with a maximum vasoconstriction the only heat that can leave the body can be driven directly by the insulating layer of the skin. This effect keeps the heat in the body. ( “Human physiology and disease mechanisms,” Guyton, pg.554)

pulses are transmitted to the adrenal medulla sympathetic while they are transferred to all blood vessels. These pulses cause bone secretes epinephrine and norepinephrine into the blood stream. These two hormones are carried by the blood to all parts of the body, where they act directly on the blood vessels, usually to cause vasoconstriction. (Ibid, pg.166)


Norepinephrine vasoconstrictor effects in all vascular beds close to the body and the adrenaline has similar effects in most, but not all. (Ibid, pg.167)

According to the results of a study, fibromyalgia, pain is induced by norepinephrine. noradrenaline adrenal hormone could be responsible for body pain associated with fibromyalgia. Completion: FM patients have pain caused by norepinephrine. This finding supports the hypothesis that FM may be a sympathetically maintained pain syndrome.

Another study – skin microcirculation and abnormal temperature of tender points in fibromyalgia patients – showed that there is a vasoconstriction of the skin of tender points of fibromyalgia patients, supporting the hypothesis that fibromyalgia is related to local hypoxia skin of sensitive points.

This makes sense, norepinephrine causes vasoconstriction is probably responsible for pain associated with trigger point of fibromyalgia.

How it affects drop in body temperature fibromialgia

temperature of exercise and the body in fibromyalgia

Some studies have shown that exercise the person with fibromyalgia and chronic fatigue syndrome / MS actually experience drop in body temperature. When the opposite response is expected.body temperature in fibromyalgiaor oxygen in the brain – the opposite of what happens in normal people. The lack of oxygen in brain persisted for several days even after a short activity “- Ismael Mena,” Study of cerebral perfusion in patients NeuroSPECT with chronic fatigue syndrome ”

Reply to exercise a healthy person

In a healthy person exercise increases blood flow and oxygen supply to the cells. The cells produce ATP, is widely used to produce heat in the body. With the increase in body temperature more increase metabolism, energy production and heat. The metabolic rate increases by 15% for every degree Celsius of body temperature.

abnormal responses in fibromyalgia and CFS / ME

In the case of a person with CFS / FM, causes of exercise increases blood flow to the extremities.

But because of blockages that prevent mitochondrial energy production is less ATP generated. ATP generated is used as fuel for the activity of the year is relatively small, it is available for heating. Much of the ATP is generated by the anaerobic process of glycolysis. The accumulation of a byproduct of glycolysis, pyruvic acid, causes becomes more acid in tissues, indirectly blocking mitochondrial energy production.

As blood is pumped out of the bodies and tissues do not generate much heat,    the net effect is that the blood is cooled, thereby lowering the body temperature   . That would explain the findings in the study of the effects of exercise and CFS.

You can probably deduce that massage can also have a similar effect to lower body temperature.

One goal of the massage increases blood circulation in the tissue. This is the opposite of one of the objectives of vasoconstriction in the tissues, it is to retain body heat. The increased blood circulation in the tissue by the thermal massage tissue.

The consequences of the increase in   noradrenaline

But at what cost? Going down the body temperature? And how your body will react? Probably the adrenal glands secrete norepinephrine for more blood flow and conserve heat. With    the increase in norepinephrine can also be an increase in pain   .

Summary; Because locks of energy production mitochondrial ATP, the body is able to maintain the desired operating temperature of 37 degrees. To conserve heat, blood flow to the extremities decreases vasoconstriction of the hormone norepinephrine. High levels of norepinephrine in the blood contributes to physical pain. Exercise has the effect of reducing body temperature more in people with chronic fatigue syndrome and fibromyalgia.

more noradrenaline secreted to conserve heat, resulting in more pain.

tips and tricks

Exercise is good. But be careful not to overdo it. You have to dress well to minimize heat loss. If the outdoor air temperature is cold or cool, put on a hat and gloves more warm clothes. Most body heat escapes made head.

Walking is probably one of the best exercises you can do. If you are not able to do, stretching, gradually increase the amount of exercise you can tolerate.

If you have a sauna, finish the workout with some time in the sauna and drink a couple of glasses of water. This will help move some metabolic acid waste your body.

If you massage, find a / therapist first warm up your body before massaging you. There are massage therapists now use saunas. heat massage before and after the other in thermal FIR. Drink a glass of water before and after contributing to release the body of metabolic waste.
