Obstructive sleep apnoea is a condition in which breathing repeatedly stops or becomes shallow during sleep, and it is closely linked to high blood pressure. Although CPAP helps treat sleep apnoea, it usually lowers blood pressure only a little, so additional non-drug strategies may be useful. The study will compare two situations in the same participants: one session of wall squat exercise and one non-exercise control session. Each participant will take part in both sessions, but the order will be random. This design helps the researchers compare blood pressure changes more fairly within the same person. Participants will first attend a familiarization session, where the study procedures wil
