Women have higher core body temperatures than men. A study done by the University of Maryland School of Medicine published in the JAMA Network found that while body temperature does vary from person to person, day to day, women's body temperatures were consistently higher than their male counterparts'.
The hormones oestrogen and progesterone, found in large quantities in women, contribute to the core body and skin temperatures. Oestrogen dilates blood vessels at the extremities.
Although men and women maintain an internal body temperature of 98.6 degrees, men typically have more muscle mass and generate more heat by using more calories to fuel those extra muscles.
The warmest parts of the human body are the head, chest and armpits. Conversely, the coldest parts are the feet and toes, which are farthest from the warm-blood-pumping heart.
The armpit (35.9℃) is the coldest part of our body that is usually measured. Here are four other factors that affect our body temperature – and may be the reason behind why some people always feel cold.
Most healthy humans have an inner body temperature that hovers around 98.6 degrees F. But a University of Utah study published in the journal Lancet found that women's core body temperatures can actually run 0.4 degrees F higher than men's on average.
A slower metabolism causes women to produce less heat so they tend to feel colder. “It's simple physics,” says Boris Kingma, PhD, a thermophysiologist, at The Netherlands Institute for Applied Science (TNO). “If you lose more heat than your body produces, your body temperature will go down and you will sense that.”
Even at rest, your muscles produce around 25% of your body's normal temperature, so more muscle mass means a greater heat production.
The warmest parts of the human body are the head, chest and armpits. Conversely, the coldest parts are the feet and toes, which are farthest from the warm-blood-pumping heart.
Given that escape testing revealed a greater sensitivity of males to heat but a greater sensitivity of females to cold, it follows that a similar sex difference should be observed for thermal preference testing.
The average normal body temperature is generally accepted as 98.6°F (37°C). Some studies have shown that the "normal" body temperature can have a wide range, from 97°F (36.1°C) to 99°F (37.2°C). A temperature over 100.4°F (38°C) most often means you have a fever caused by an infection or illness.
Females of most vertebrate species exhibit recurring periods of heightened sexual activity in which they are sexually attractive, proceptive and receptive to males. In mammalian females (except Old World monkeys, apes and humans), this periodic sex appeal is referred to as 'heat' or 'estrus'.

Cold intolerance is a frequent complaint among those who have lost a considerable amount of weight. The body's core has lost a significant part of its protection against heat loss. The problem is usually worse for those who become very thin, especially small women.
Researchers found that not only do subcutaneous fat reserves act as a layer of insulation, hindering heat exchange and therefore the cooling process, but that overweight people produce more heat.
Humans with obesity cool less rapidly and have to elevate their metabolism less significantly than lean individuals when immersed in water. Although obesity provides an advantage in cold conditions it conversely impedes heat loss and makes obese people susceptible to heat stress more than lean individuals.
For starters, men tend to run hotter than women as a result of having more muscle mass, which generates more heat than fat. "Body temperature is a reflection of metabolic rate — if somebody pushes a lot of weights they will push their basal metabolic rate up and run hot," Professor Dawson told 9Honey Coach.
Women are more likely to feel cold all the time, in part because they have a lower resting metabolic rate. This means they naturally generate less energy, or body heat. A small 2015 study also suggests that women may have a lower tolerance for cold sensations in the hands.
Environmental and lifestyle factors, medications, age, hormones, and certain emotional states can all affect body temperature. However, a persistent feeling of being hot sometimes signals an underlying health condition. Depending on the cause, a person who feels hot may sweat excessively or not sweat at all.
It's not clear exactly how hormonal changes cause hot flashes. But most research suggests that hot flashes occur when decreased estrogen levels cause your body's thermostat (hypothalamus) to become more sensitive to slight changes in body temperature.
According to a new study published in the journal Evolution and Human Behavior, women with a 'low waist-to-hip ratio (WHRs)' – commonly known as an 'hourglass figure' – are seen to have the most attractive bodies.
In general, women feel colder than men do at the same air temperature. They prefer rooms at 77 degrees Fahrenheit, while men prefer 72. Body size and fat-to-muscle ratios are largely to blame for that discrepancy.
