Why are you hungry in winter?

It's really easier to get hungry in winter. Cold can accelerate gastric emptying and increase the body's metabolic rate, so it is easier to get hungry.

First of all, the weather is cold in winter, and cold will stimulate gastrointestinal peristalsis and accelerate gastric emptying. Secondly, the metabolic rate of the body will increase in winter, and the body needs to increase the metabolic rate to resist the cold outside, so the energy consumption rate is faster, so it is easier to be hungry in winter. Attention should be paid to protecting the gastrointestinal tract in winter, which is susceptible to many factors, mainly physical, chemical and biological factors. Physical factors mean that the ambient temperature and food temperature are too high or too low, chemical factors mean that food is too irritating, and biological factors mean that food is contaminated by microorganisms.

In winter, we should pay attention to the maintenance of diet and environmental temperature to avoid the stimulation of gastrointestinal tract by too low temperature. Diets should be supplemented with thermogenic nutrients, such as carbohydrate, fat and protein, to improve the body's tolerance to low temperature.
