What to do if your knees hurt due to cold

The knees are relatively fragile and prone to sports injuries and the effects of wind and cold. If the knees catch cold, it can easily lead to arthritis, which can cause difficulty in movement and pain and swelling when walking. When pain is caused by wind and cold, you should strengthen your diet. If the condition is serious, you should go to the hospital for examination in time. Certain physical therapy can also be very effective.

What to do if your knees hurt due to cold

1. High calcium diet:

This is a fundamental measure to prevent calcium deficiency and is also an economical and safe method of calcium supplementation. The WHO specifies that the preventive dose of calcium is 500 mg per person per day, and the therapeutic dose is 1000 mg per person per day. Usually the absorption rate of calcium in food is only 30%. Milk and soy products are good sources of calcium. Other foods high in calcium include dried shrimp skin, kelp, seaweed, oysters, seaweed, sesame paste, etc. Animal bone soup is also rich in calcium, but you need to add some vinegar during the cooking process to promote the dissolution of calcium and facilitate calcium absorption.

2. Appropriate amount of protein:

It is best to choose high-quality protein, such as eggs, lean meat, fish, shrimp, chicken, soy products and other foods. However, excessive protein will produce acidic substances during metabolism in the body, which will increase the excretion of urinary calcium and lead to increased calcium loss in the body.

3. Eat more foods rich in vitamin C:

For example, fresh vegetables and fruits can promote calcium absorption and are beneficial to the formation of bone matrix. However, it should be noted that some vegetables (such as spinach, water spinach, wild rice stem, winter bamboo shoots, etc.) contain more oxalic acid, which can combine with calcium to form insoluble calcium oxalate, affecting and preventing the body's absorption of calcium. Therefore, middle-aged and elderly people should boil these vegetables in water before eating them to remove the oxalic acid in the vegetables.

4. Low phosphorus diet:

When blood phosphorus increases, blood calcium decreases, and calcium absorption from the intestine is also poor. Therefore, you should eat less high-phosphorus foods, such as cola.

5. Low salt and low sugar diet:

Develop a good lifestyle and habits, quit smoking, limit alcohol, and drink less coffee to eliminate obstacles in the calcium absorption process.

6. Exercise appropriately:

Reduced exercise can easily cause calcium to be removed from the bones, leading to loss of bone mass and causing osteoporosis. Therefore, middle-aged and elderly people should regularly participate in physical exercise, such as walking, swimming, and Tai Chi, to increase bone toughness, increase bone mass, and improve the ability to resist fractures.

It is not recommended that children and middle-aged and elderly people receive more sunlight exposure, which can promote the synthesis of vitamin D3 and thus increase the absorption of calcium from the small intestine. Since ultraviolet rays cannot pass through glass, clothes, dust, smoke, etc. can block the passage of ultraviolet rays. Therefore, when sunbathing, you should try to make your skin directly contact with the sunlight. Do not sunbathe through glass. Only in this way can you get good results.
