Some people have a naturally hotter body temperature than others. The human body temperature is defined as 37.5°C which is an average and people’s natural body temperature falls in a small range around this figure.
The fluctuation is very small and any body temperature over 38°C is considered a fever. However, naturally warm people may find it harder to cool down to a comfortable temperature when sleeping, increasing the chances of night sweats.
Part of heat regulation is done by the thyroid gland which generates and responds to hormones. When there is a hormonal imbalance in the body, it can disrupt the body’s thermoregulation patterns and lead to overheating.
Changes in hormones can be caused by medications, endocrine disorders such as hyperthyroidism or external factors such as stress.
Hormonal changes can also be caused by natural bodily changes. The menstrual cycle causes a fluctuation of hormones that can lead to overheating and body sweats.
The changes in hormone levels during pregnancy and the menopause are also a source of hormonal overheating. These occur as oestrogen levels drop and the brain responds by increasing body temperature.
Overheating is a potential symptom of a huge range of conditions that an individual may be dealing with. This can include various viruses such as HIV, cancers, infections, autoimmune disorders, neuronal conditions and psychological disorders.
Various medications can have heat increasing side effects. These range from common blood pressure drugs to antipsychotics and antidepressants. There are also many drugs that affect hormone levels which can in turn lead to overheating.
