The sun is shining, the green trees are rich, the melons and fruits are fragrant; the enthusiasm is spirited and purgatory-like flowing fire, the breeze gently caresses the maiden-like graceful moonlit lotus pond; gorgeous and colorful, thunderous, no season comes more romantic, charming and changing than summer. The state of mind swings with the poet’s pen from time to time, but the doctor’s profession, landing on the thought more than anything else is to let oncology patients enjoy life and happiness have the summer they can look forward to. Sunshine. The world is wonderful without sunlight, but too strong sunlight exposure will weaken the body’s immune system, which may add to the already damaged immune system of cancer patients. Patients during treatment have more sensitive skin to sunlight exposure. Many chemotherapeutic drugs, such as fluorouracil, are associated with an increased incidence and severity of drug-related skin reactions, in addition to skin burning, after sun exposure. In radiotherapy patients, the skin in the radiotherapy area is even more prone to severe damage and should be absolutely protected from direct sunlight. It is best to avoid going out and arrange outdoor activities in the morning and evening, as 10:00 a.m. to 4:00 p.m. is the most intense time of the day. Apply sunscreen. Choose a product with an SPF of 15 or higher, and reapply if necessary. After heavy sweating, bathing or swimming, sunscreen will come off and need to be reapplied. Note: Sunscreen may irritate the skin and product selection should be done in consultation with the treating physician to avoid additional damage to the skin. Physical facilities shield the skin in the treatment area. Dark and dense textile fabrics are better for protection than light colored thin and loose fabrics Head and face protection. More attention should be paid to surgical scar protection for people with hair loss. Especially new scars are prone to injury and darkening after sun exposure. High temperature and dehydration. The side effects of treatment such as nausea, vomiting, diarrhea, and anorexia often lead to decreased intake and increased loss of water and sodium chloride, and high temperatures increase this loss; therefore, oncology patients under treatment in summer are prone to dehydration, or heat deficit. Measures to prevent this include: Drink water before you get thirsty. Drink at least 6-10 glasses of water a day, and even more often when you are out or in the heat. If you cannot drink water, make sure to replenish it through intravenous or other means. You can drink iced water, or drinks with ice, to quench your thirst and cool you down quickly.

Try not to use synthetic fibers, rayon, etc. Apply continuous ice to rash-prone areas. Reduce the temperature of air conditioners and use fans. Take a shower before going to bed. If you are physically able to exercise, consider swimming. Beverages containing alcohol or coffee can increase the occurrence of rashes Exercise. Summer is a good time to exercise, and exercise can make you better able to cope with the adverse effects of treatment. However, consultation with your primary care physician is recommended for the development of a specific plan. Wigs.
