Seasonal change is the law of nature, alternating seasons, year after year. Spring is born, summer grows, fall harvests, winter hides, so are crops and so are people. Winter is an “eventful season” for tumor patients, and if they do not pay attention to their health care in winter, it is easy to aggravate the disease. So how to maintain health scientifically in winter? Do the following points, help you safe winter: First, winter weather is dry, hydration is the focus of health, an adult drinking water every day at a minimum of 1,500 ml, dry winter drinking more than 2,000 ml of water every day in order to maintain the lubrication of the airways. People eat every day in the food already contains a lot of water (vegetable water content of 90%, fruit water content of 80%, fish, meat water content of 70%), after deducting these, the daily water intake in 1500 milliliters is about the same, excessive drinking water may also cause “water intoxication”, endangering the health of human beings. How to determine whether you are dehydrated or not? Urine is an important basis for judging whether you need to drink water or not. Several reasonable drinking water time points are: 1, get up; 2, 10:00 am and 3:00 pm or so; 3, half an hour to an hour before meals; 4, half an hour to an hour before going to bed; 5, tumor patients also need to drink more water during chemotherapy, which can reduce the drug’s nephrotoxicity. Secondly, the cold weather does not mean that the virus and bacteria spread slowly, on the contrary, tumor patients due to anti-tumor treatment, resistance to decline, is a variety of infectious diseases susceptible population, so special attention should be paid to: 1, keep warm while paying attention to open windows and ventilation; 2, more vitamin-rich fruits and vegetables 3, to avoid frequent entry and exit of crowded and confined public places; 4, but never remember to make appointments with the doctor for review and treatment should not be delayed! The treatment can not be delayed Oh! Third, it is often said that the big dream of three lives, no disease, no yo, Chinese medicine believes that: winter in March, lie down early and get up late, must wait for daylight, the way to raise Tibetan also. For the tumor cells full of “negative energy”, maintaining a positive and healthy mindset, more communication with family members, good sleep and energy is a powerful weapon to defeat the tumor. Tumor patients are often accompanied by emotional depression, often manifested as lack of energy, easy to fatigue, depressed, unwilling to communicate, sunbathing is a very good way to maintain a happy mood, but also increase the body’s vitamin D, delay aging! At the same time, the moderate extension of sleep time and the improvement of sleep quality can play a multiplier effect. Fourth, after tumor patients’ surgery, the surface of the body usually leaves a long surgical scar. Scar is formed when the skin tissue of human body is traumatized and the skin fibrous connective tissue proliferates to fill, connect, support and protect the surrounding normal tissues. In other words, scar formation is the body’s normal biological repair process. The hot and cold changes in winter weather can also cause the scar to contract and relax, triggering pain, itching and other abnormal sensations. At this time, vitamin E ointment can be applied to the skin to nourish and moisturize the skin, and at the same time with the local massage of the scar, to promote the blood circulation of the scar and reduce the symptoms.
