Our internal body temperature is regulated by a part of our brain called the hypothalamus. The hypothalamus checks our current temperature and compares it with the normal temperature of about 37°C. If our temperature is too low, the hypothalamus makes sure that the body generates and maintains heat.
What causes your body to not regulate temperature?
One of the most common causes of heat intolerance is medication. Allergy, blood pressure, and decongestant medications are among the most common. Allergy medications can inhibit your body's ability to cool itself by preventing sweating.
Is it possible to regulate your temperature?
Summary: Scientists have shown, for the first time, that it is possible for core body temperature to be controlled by the brain.
