<P> Generally speaking , the body suspends homeostasis during paradoxical sleep . Heart rate , cardiac pressure , cardiac output , arterial pressure , and breathing rate quickly become irregular when the body moves into REM sleep . In general , respiratory reflexes such as response to hypoxia diminish . Overall , the brain exerts less control over breathing ; electrical stimulation of respiration - linked brain areas does not influence the lungs , as it does during non-REM sleep and in waking . The fluctuations of heart rate and arterial pressure tend to coincide with PGO waves and rapid eye movements , twitches , or sudden changes in breathing . </P>
