The hot summer has come, which is a challenge for everyone, and for lung cancer patients, the hot summer adds to the pain of the disease. Because of the disease itself, many patients’ lung function is already in a state of loss of compensation, and they will have symptoms of cough, chest tightness and shortness of breath, and the low air pressure and poor air circulation in summer add to the burden of lungs, which brings great pain to patients. So, how should lung cancer patients spend summer safely and comfortably? 1.Environment As the temperature is high in summer, it is very important to maintain a cold and ventilated environment. Patients’ rooms should pay attention to ventilation to keep indoor air fresh and avoid heat stroke. At the same time, do not make the indoor temperature too low or temperature change too much, so as not to cause cold and induce a cold. 2. Diet The hot summer weather makes it easy to sweat a lot, resulting in loss of water and electrolytes in the body, which can cause symptoms such as weakness, loss of appetite and poor mental health. Therefore, in the hot summer, patients should maintain a fixed daily water intake, and maintain an appropriate amount of salt intake. Do not drink large amounts of cold beverages as this may affect the digestive function and lower the resistance. Diet should include light, nutritious and easily digestible foods, such as lean meat, eggs and fish, which can promote wound healing and improve the immune function of patients after surgery. In hot summer, lung cancer patients should pay attention to rest and ensure sufficient sleep to improve their resistance, and also pay attention to proper exercise to promote body blood circulation and increase body immunity. Prof. Chen Jun of the Department of Pulmonary Oncology Surgery of Tianjin Medical University General Hospital said: Summer is a challenge for lung cancer patients, and for postoperative lung cancer patients, they should pay attention to postoperative wound care to avoid wound infection. Therefore, it is important to keep the surgical incision sterile outside the hospital. As for lung cancer chemotherapy, summer cold is another serious challenge. During chemotherapy, patients will suffer from bone marrow suppression, which is a period of low immunity, and a cold at this time will easily cause lung infection and increase the burden on heart and lungs, which may even be life-threatening in serious cases. Therefore, patients should be careful not to stay in the air-conditioned room for a long time and avoid cross-infection with others. If they already have symptoms of cold and fever, they should come to the hospital in time.
