The human brain is responsible for the regulation of body temperature, and this can be achieved through the help of the skin, blood vessels and sweat gland. You can’t regulate body temperature without them. For warm-blooded animals such as humans, the internal body temperature ranges around 37 °C (98.6 °F) when measured by mouth, and ranges around 38 °C (100.4 °F) when measured through the rectum. Although external temperatures fluctuate greatly, the body temperature is maintained if the body functions well.
The body temperature is regulated by balancing heat gain and heat loss. The body gains heat through metabolism (converting food into energy) and through muscles' work during activities. Heat loss is achieved through:
The body temperature can also be cooled through convection such as taking a bath and through conduction like lying on cold ground.
It is extremely difficult for you to regulate your body temperature if you suffer from either of these conditions. A well functional thyroid hormone helps the body to make 65% energy and 35% heat through the burning of calories for fuel. The thyroid hormone is responsible for regulating basal metabolic rate, and it also helps to speed up the rate of energy production, which is important to maintain your body warm. A poor thyroid function either leads to hypothyroidism (a condition whereby you feel too cold) or hyperthyroidism (a condition whereby you feel too hot).
This is a two-way thing. Anxiety can lead to change in body temperature in several ways, and it is also possible for a sudden change of a normal body temperature to cause anxiety. Some issues that can cause anxiety to affect the regulation of body temperature include:
Other than these issues, there are other factors that can cause anxiety to affect our body temperatures: Goosebumps can be created by anxiety, which may keep the body cool; hyperventilation can also cool the body system; anxiousness can make you move, thus causing you to feel hot.
Constant fluctuation of body temperature can be detrimental to the body as a whole. Other causes of temperature fluctuations include deficiency in vitamin C, diabetes, and autoimmune diseases such as sjorgern’s syndrome or lupus.
Fluctuation in body temperature can be caused by underlying diseases listed above. Your system can’t regulate body temperature with these diseases in place. Therefore, it is important to seek medical help if you have difficulties in regulating your body temperatures.
Hypothyroidism can be corrected by the use of the synthetic hormone levothyroxine like synthroid and levothroid, etc. It can also be corrected by using natural extract gotten from the thyroid gland of pigs. These extracts contain thyroid hormone that helps to reverse this condition.
This condition can be corrected by using antithyroid medications which help prevent the production of excess thyroid hormones. These medications are mainly methimazole and propylthiouracil, but the latter is only suitable for women in their early stage of pregnancy. Radioactive iodine treatment can also be used in correcting this condition. What's more, surgery could be carried out in some rare cases where people don’t respond to other options. Other forms of treatment such as beta-blockers may also be prescribed to you by your doctor.
As anxiety is one of the main reason why you can't regulate body temperature, you should try to deal with it.
