Men often prefer cooler rooms because they generally produce more body heat due to higher muscle mass and metabolic rates, making them feel warmer, while women tend to feel colder due to less muscle, different fat distribution, and lower metabolism, plus factors like circulation and hormones. This difference means the standard office temperature (often based on older male-centric studies) is often too cool for many women, but comfortable or even too warm for men, who can also perform better in cooler conditions.
Some studies have shown that while men feel comfortable in rooms with the thermostat set at 72 degrees, women tend to feel comfortable in rooms with the thermostat set at 77.
You get a natural melatonin boost.
Cooler environments support melatonin production. This hormone doesn't just regulate sleep—it also plays a role in mood and helps reduce oxidative stress, which can affect how you feel and function during the day.
The air conditioning in most office buildings was actually determined by a several decades old study that only took into account the metabolic rates of men to calculate ideal room temperature for work performance. On average, women prefer the thermostat set several degrees warmer than men.
A comfortable room temperature for most people is usually between 18-20 °C, however it largely depends on the individual. Whatever the season, it is recommended that you use a thermostat to monitor how the temperature fluctuates throughout the day.
What Is the Ideal Room Temperature in Winter and Summer? In general, the ideal room temperature and your home for both efficiency and comfort fall somewhere between 68° and 76°F.
Sleeping in a cold room may help sleep quality and reduce diabetes risk. Sleep is key for overall health and wellbeing—and research suggests that sleeping in cooler temperatures around 65 to 68 degrees Fahrenheit may support your health even more.
Women feel significantly colder than men in cold environments. Women have significantly lower mean skin temperature than men in cold environments. Women have significantly higher body core temperature than men. Menstruation, pregnancy, and menopause affect women's thermal assessment.
However, as you age, you start to lose your extra muscle mass, thought to be at a rate of around 10% for each decade after the age of 50. This is one of the reasons that older people often feel the cold more later in life.
This may vary by a few degrees from person to person, but most doctors recommend keeping the thermostat set between 65 to 68 degrees Fahrenheit (15.6 to 20 degrees Celsius) for the most comfortable sleep.
So sleeping in a cold bedroom is better for sleep, because overheating interrupts not just one but two crucial sleep phases; Deep Sleep and REM sleep. A lot goes on in the Deep Sleep and REM stages of our sleep cycle.
Are you a chionophile? If you are loving this cold weather, then you might just be!
Men typically have a higher percentage of muscle mass compared to women, and muscle generates more heat than fat. This means that not only do men produce more heat, but they also retain it longer, making them feel warmer during sleep.
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. And women's hands can be significantly colder — 82.7 degrees F on average, compared with 90 degrees F for men.
In the women and men, the highest Tmean temperatures were found on the trunk. The warmest were the chest and upper back, then the lower back and abdomen. The lowest Tmean were found in the distal parts of the body, especially on the lower limbs.
Less Insulation From Body Fat
Fat cells also release energy when they sense cold temperatures, which helps keep you warm. When body fat drops too low, you lose insulation, causing you to feel more sensitive to a dip in temperature.
The researchers described 39 years old as this "inevitable" age that people reach in which they start to feel more disconnected with what is currently "cool," or when respondents "generally expect to feel out of touch."
These findings indicate that females are more sensitive to emotional expressions in real interpersonal interactions, which is manifested in both early motivational salience detection and late conscious cognitive appraisal stages of feedback processing.
Studies of experimentally induced pain have produced a very consistent pattern of results, with women exhibiting greater pain sensitivity, enhanced pain facilitation and reduced pain inhibition compared with men, though the magnitude of these sex differences varies across studies.
However, recent studies have shown that females are more sensitive to affective touch, as well as to discriminative aspects of touch. In fact, females rated affective touch and non-affective touch stimuli as more pleasant and had higher tactile acuity than males.
In Japan, it is standard practice to heat only the living room, rather than heating the entire apartment or house, as seen in Europe and America. It is not common to heat the bedroom in Japan. As a result, average bedroom temperatures are much lower in Japan.
"If the temperature of your bedroom drops too low, it can cause muscle stiffness, restlessness, or general discomfort, particularly for children or the elderly," he says. "People with asthma or respiratory conditions may also find that overly cold, dry air irritates their airways."
The best room temperature for sleep is between 66 to 72°F. Your skin should ideally be between 88 to 95°F during sleep. The temperature under your bed covers should be around 90 to 93°F with 40% to 60% humidity.
