What effects do opioids have on sleep?

What effects do opioids have on sleep?

• A. REM, SWS, TST, SE
• B. N1 and wakefulness
• C. REM latency only
• D. N2 only

Answer: (A)

Opioids broadly alter sleep architecture, not just one aspect. They tend to suppress both rapid eye movement (REM) sleep and slow-wave sleep (deep sleep), while also increasing light sleep and causing more frequent awakenings. This combination reduces overall sleep time and lowers sleep efficiency because you spend more time awake or in lighter stages despite being in bed. So, opioids impact REM, SWS, total sleep time, and sleep efficiency all at once, making the option that includes REM, SWS, total sleep time, and sleep efficiency the best description. Looking at the other possibilities, they point to changes in only a single stage or metric (for example, a change in a single sleep stage or only one aspect like REM latency), which doesn’t reflect the broad effect opioids have on sleep.
