Winter's cold weather affects the body's physiological functions and appetite, among other things. Therefore, adjusting one's diet appropriately to ensure sufficient intake of essential nutrients is crucial for improving cold resistance and immune function, enabling one to safely and smoothly get through the winter. Below are some suggestions on health and dietary knowledge for winter care, for your reference only.

　　Methods/Steps

　　First and foremost, it's essential to ensure adequate energy intake. This is common sense. The cold winter weather affects the body's endocrine system, increasing the secretion of hormones like thyroid hormones and adrenaline. This promotes and accelerates the breakdown of the three major energy-generating nutrients—protein, fat, and carbohydrates—to enhance the body's ability to withstand the cold. However, this also leads to excessive heat loss. Therefore, winter nutrition should focus on increasing energy intake, with a moderate increase in foods rich in carbohydrates and fats. For the elderly, fat intake should be limited to avoid triggering other health problems, but sufficient protein intake is crucial. Increased protein metabolism can lead to a negative nitrogen balance. Protein intake should ideally account for 15-17% of total calories, primarily from sources like lean meat, eggs, fish, dairy products, beans, and their derivatives. These foods contain proteins that are easily digested and absorbed, are rich in essential amino acids, and have high nutritional value, enhancing the body's cold resistance and disease resistance.

　　What to do when you have mouth ulcers in winter? If you have blisters in your mouth, chew a few slices of ginger; this can help the blisters gradually disappear. Before bed, wash your face and apply some eye ointment to the painful area of ​​your lips; the pain will lessen the next day. Continue applying for a few days until the pain disappears. For nasal congestion: If your left nostril is blocked, lie face down or on your right side. Support your right neck with your right hand, palm near your earlobe, lifting your head to the right, and extend your elbow upwards and to the right as far as possible. Due to the stretching effect of the meridians, the nostril should clear in a few seconds to several tens of seconds. If your right nostril is blocked, do the opposite. If both nostrils are blocked simultaneously, alternate the movements.

　　Winter Dietary Tips: What to Eat in Winter? Winter is the off-season for vegetables, with fewer and less varied options, especially in northern China. As a result, many people experience vitamin deficiencies after winter, such as a lack of vitamin C, leading to symptoms like mouth ulcers, swollen and bleeding gums, and constipation in the elderly. Prevention methods include expanding food sources. Since leafy green vegetables are relatively scarce in winter, it's good to eat more root vegetables like sweet potatoes and potatoes. These are rich in vitamins C and B, especially vitamin A. Red sweet potatoes also contain a lot of carotene and have a cooling effect. In addition to Chinese cabbage, other common winter vegetables include round cabbage, red radishes, white radishes, carrots, soybean sprouts, mung bean sprouts, and rapeseed. These vegetables are all rich in vitamins. By regularly changing the types of vegetables and combining them appropriately, you can supplement your body's vitamin needs. The cold winter weather can also affect the body's metabolism, increasing the consumption of various nutrients. Due to metabolic factors affecting digestion and absorption, older adults often lack elements such as potassium, calcium, sodium, and iron. Furthermore, increased urination in winter leads to a greater excretion of these minerals. Therefore, timely replenishment is essential. Consuming foods rich in calcium, iron, sodium, and potassium, such as dried shrimp, shrimp shells, sesame paste, pork liver, and bananas, is beneficial. For those with low sodium levels, slightly increasing the salt content in cooking can help.

　　What to eat to relieve internal heat in winter? With the arrival of winter, many people experience internal heat due to the combined effects of heating and dry environments. Symptoms include dry, hoarse throat, sore throat, and mouth ulcers. What can you do to stay refreshed and comfortable during winter? For dry, hoarse throat: drink lightly salted water; take pear syrup; drink tangerine peel and sugar tea. For sore throat: eating raw pears can prevent and treat mouth ulcers and sore throat; gargling with equal parts vinegar and water can relieve pain; gargling frequently with the juice of mashed tender loofah; for a sore throat, gargling with a spoonful of soy sauce for about one minute, repeating 3-4 times, is effective .
