Whether a man loves you or not, you'll know with just one cold snap

The biggest fear in winter is not low temperature warning, but the sudden "cooling mode" of the object - even though they are wrapped in the same blanket, their side is as warm as spring, and your hands and feet are cold. This temperature difference is often used to test emotional concentration, but you may not know that differences in the body's response to cold contain more complex physiological codes than love. Why are some people born like small stoves?

1. Differences in basal metabolic rate

Male muscle mass is generally 15% -20% higher than that of females, and the daily calorie consumption per kilogram of muscle in a resting state is three times that of fat. This is like two air conditioners, one in energy-saving mode and the other always on with strong heating.

2. Hidden thermostat of hormones

Testosterone promotes red blood cell production and vascular constriction, while estrogen tends to dilate subcutaneous blood vessels. When the cold wind blows, the blood flow on the surface of male skin may be 30% less than yours, just like automatically turning on the "insulation mode".

2. Cold hands and feet may not necessarily be a warning of love

1. Individual differences in peripheral circulation

The temperature of fingers and toes reflects the microcirculation status more. Some people have naturally thinner capillaries, like the pipes in an old house, and it takes longer for hot water to reach the end when it's cold.

2. Sensitivity of the Temperature Regulating Center

The hypothalamus is like the body's intelligent temperature control system. Some people have particularly sensitive sensors, and when the ambient temperature drops by 1 ℃, the warming mechanism will be activated. However, people who are slow may only react when the temperature drops by 5 ℃.

3. A Warmth Plan More Important than Measuring Love

1. Dynamic Warming Techniques

Actions such as shaking legs and rubbing hands are actually scientifically effective. Rapid muscle contraction can generate heat, but it is more recommended to do several sets of squats or high leg lifts, just like installing a mini generator inside the body.

2. Dietary regulation strategies

Iron rich foods can enhance hematopoietic function, just like recharging the blood. At the same time, avoid catching a cold on an empty stomach, as the digestive process itself can cause a 0.5-1 ℃ increase in body temperature.

Emotional thermometers should not only look at physiological reactions, true lasting warmth comes from mutual understanding. When you stick your ice feet against it, whether the other person avoids or holds onto it may be more indicative than the ability to maintain a constant temperature. This winter, let's use knowledge instead of probing, and communication instead of suspicion.
