Doctors Explain Why You ‘Run Hot’ Or ‘Run Cold’

Have you ever wondered why some people are more prone to feeling warm while others seem to be forever reaching for an extra layer? The phenomenon of feeling either “run hot” or “run cold” is more than just a personal preference; it’s deeply rooted in the complex workings of our bodies. We asked medical experts to explain the reasons behind these temperature variations.

Metabolism Matters: The Core Engine

One of the primary factors influencing whether you tend to run hot or cold is your metabolism. Metabolism refers to the countless chemical processes that sustain life within our cells and the rate at which these processes occur. Individuals with a higher metabolic rate tend to produce more heat, making them feel warmer. On the other hand, those with a slower metabolism may find themselves reaching for a blanket more often.

Blood Circulation: The Heat Distribution


How efficiently our bodies circulate blood also plays a pivotal role in temperature regulation. Blood carries heat throughout the body, ensuring a balanced distribution. People who run hot usually have excellent blood circulation, efficiently delivering warmth to all body parts. Conversely, those who run cold may have slightly compromised circulation, leading to cooler extremities.

Thyroid Troubles: A Common Culprit

The thyroid gland in the neck plays a vital role in regulating body temperature and metabolism. An overactive thyroid (hyperthyroidism) can rev up the body’s heat production, causing individuals to feel warmer than usual. Conversely, an underactive thyroid (hypothyroidism) can slow metabolism, leading to feeling cold more often.

Gender Differences: The Battle Of The


It’s no secret that men and women often have different temperature experiences. Studies have shown that women generally have a higher core body temperature than men. Hormonal fluctuations throughout the menstrual cycle can also impact how warm or cold a woman feels at different times of the month.

Body Composition: Muscle Vs. Fat

Muscle and fat play contrasting roles in temperature regulation. Muscle generates more heat than fat, so individuals with a higher proportion of muscle mass are likely to feel warmer. Conversely, those with more body fat may feel colder since fat does not produce heat as efficiently as muscle.

Environmental Influences: Weather And


Apart from individual factors, external conditions also influence our perception of temperature. Exposure to cold weather or being in chilly environments can make anyone feel colder, regardless of their natural temperature tendencies. Similarly, hot weather or a well-heated room can make even the warmest individuals feel hot and sweaty.
