For people living with psoriatic arthritis (PsA), the comfort of a good night's sleep may feel out of reach for many. Psoriatic arthritis is associated with a number of sleep problems, including trouble falling and staying asleep, poor-quality sleep and feeling sleepy during the day. Clinical observations have suggested that the higher the PsA disease activity, the worse the sleep quality may be, although even those with minimal psoriatic arthritis symptoms may have difficulty sleeping.
