Sun exposure can be beneficial for psoriasis, but it should not be for excessively long periods. When you have psoriasis, you should choose the right time for sun exposure. In winter, when the sunlight is gentler, it is appropriate to sunbathe, and you can also sunbathe indoors behind glass. In the summer, it is important to choose the right time, such as early morning or evening when the sunlight is not too intense, to enhance the skin's tolerance in psoriasis patients, allowing for normal sun exposure.

Additionally, it is important for individuals with psoriasis to engage in appropriate exercise to boost immune function. During bouts of psoriasis, attention must also be paid to diet, avoiding spicy and irritating foods, avoiding staying up late, and following a doctor's guidance in using Chinese herbal medicine, Western medicine, or a combination of both, which typically yields a relatively ideal treatment outcome.
