Generally speaking, when the temperature drops below 10℃, you will feel cold. Cold is an animal's perception of temperature. Cold weather is often accompanied by weather phenomena such as rain, wind and snow, although cold and heat are opposite. However, feeling cold and feeling hot are indeed relative.

Warm keeping measures in cold weather

1, warm neck: can avoid vasoconstriction.

The neck connects the head and trunk, which is a fortress of the human body. Cold in the neck will make local blood vessels contract, reduce blood flow speed, and even induce dizziness, insufficient blood supply to the brain and other discomfort.

Measures: Be sure to bring a warm scarf when you go out in winter, which can resist the cold and prevent colds.

It should be reminded that many people are used to covering their necks and mouths together when wearing scarves, which is not good for their health. Because scarf fibers are easy to fall off, absorb dust and germs, and easily enter the body with breathing, causing diseases.

2, keep the stomach warm: can avoid stomach pain.

In winter, due to the stimulation of cold, the digestive function of gastrointestinal tract is weak in cold weather, and food is easy to catch cold at low temperature.

This makes patients with gastric ulcer, duodenal ulcer, chronic gastritis and other diseases prone to stomach pain, diarrhea and other symptoms, and even aggravate the condition. Even people who don't have stomach problems are prone to stomach pains if their immunity is low at this time.

Measures: Do a good job in cold prevention and warmth, especially in the upper abdomen, such as wearing a cotton vest or cotton belly to avoid catching cold in the stomach. Go out against the cold wind and don't walk against the wind.

Avoid excessive consumption of highly irritating foods, such as mutton and dog meat, especially wild animals, as well as fried foods, peppers, strong coffee, strong tea, spirits and other foods that are easy to damage the gastric mucosa.
