Supplementing foods rich in calcium and iron

People's fear of cold is related to their lack of intake of certain minerals. For example, the content of calcium in human body can directly affect the elasticity and excitability of myocardium, blood vessels and muscles; Iron deficiency in blood is an important cause of iron deficiency anemia, which is often characterized by low fever and hypothermia. Therefore, supplementing foods rich in calcium and iron can improve the body's ability to keep out the cold. Calcium-containing foods mainly include milk, bean products, kelp, seaweed, shells, oysters, sardines, shrimp and so on. Iron-containing foods are mainly animal blood, egg yolk, pig liver, soybeans, sesame seeds, black fungus and red dates.

Keep warm in snowy days

1

Keep your feet warm.

All diseases start from the feet, and all cold starts from the legs. Compared with other parts of the human body, feet are the most vulnerable to cold. Once the feet are cold, it will have a certain impact on the whole body. The most common is that it will lead to a drop in body temperature and disturb the normal physiological functions of various parts. Especially for the upper respiratory tract, it can generally cause colds, arthritis, indigestion and gynecological diseases.

Therefore, in snowy days, we should pay attention to keep our feet warm. If you have stepped on snow (not before frostbite), you'd better soak your feet with hot water. If, in the sleet or blizzard weather environment, or the snow melts, even if you wear warm shoes, you will get wet quickly, and as a result, your feet will be easily frostbitten. At this time, an inconspicuous plastic bag can help you solve big problems. You can try to put a plastic bag over your socks and put on your shoes, which will keep you warm and insulated.

The correct way to keep out the cold is to wear clothes.

In winter, we should pay attention to the "microclimate" in which clothes are in direct contact with the human body. It is not that the thicker clothes are, the warmer they are.

Winter clothing rule 1: Choose warm and comfortable clothes.

There should be a certain number of clothes and a suitable thickness in winter. Down jacket has a certain thickness, and the pores of wool fabric are not straight through, which can bring people a suitable clothing microclimate. Leather clothing can almost block the air convection in clothes, and wear leather clothing to keep warm when going out in winter.

Winter dressing rule 2: dress according to room temperature control.

In winter, the indoor temperature should not be too high, and the temperature difference between indoor and outdoor is too large, so it is easy for the human body to induce diseases such as colds because it is difficult to adapt. According to experts' research, there is a comfortable air temperature range. If the temperature is too high, it will not only cause physical discomfort, easily lead to diseases, but also affect higher nervous activity's and autonomic nerve functions, resulting in people's inattention, poor accuracy and coordination, and reduced reaction speed.

Winter dress code 3: avoid wearing a collar that is too high and too tight.

Too tight collar will compress the blood vessels in the neck, reduce the nutrients delivered to the brain and eyes, and then affect the vision, and also affect the normal activities of the cervical spine, which may easily lead to cervical spondylosis.

Some people who wear high-necked clothes turn their heads too fast, which will induce bradycardia, even cardiac arrest and hypotension, leading to reduced blood flow in the brain and temporary interruption. In severe cases, syncope, pallor and unconsciousness may occur.

Rule 4: Wear a mask for a long time.

Many people wear masks to keep out the cold. In fact, this will reduce people's ability to keep out the cold and make them more likely to catch a cold. Because there are abundant capillaries in the nasal mucosa, its function is to heat and humidify the cold air entering the nasal cavity.

Pathology of snowy days

A fall prevention: in snowy days, anti-skid, anti-fall and anti-collision are the most important for the elderly. Old people with osteoporosis are advised not to go out in snowy days.

Prevention of stroke: For people with poor vascular elasticity, the sharp change of temperature will bring blood pressure fluctuation, raise blood pressure and promote cerebral hemorrhage. Attention should be paid to finding the precursors of stroke, such as sudden dizziness, severe headache, blurred vision and numbness of limbs.

Three kinds of heart diseases: including angina pectoris and myocardial infarction. Cold can increase the content of fibrinogen in blood, which is easy to cause thrombosis and block coronary blood vessels. The diseased coronary artery contracts when it is cold, blocking blood vessels, leading to myocardial ischemia and hypoxia and inducing angina pectoris.

Prevention of digestive tract ulcer: under the reflex action of parasympathetic nerve, the stomach produces spasmodic contraction, which leads to ischemia and hypoxia of the stomach itself and the recurrence of gastric disease.

Prevention of respiratory diseases: including colds, coughs and pneumonia.

Prevention of gas poisoning: taking a bath with gas or heating with a coal stove may cause carbon monoxide poisoning.
