Sleep paralysis often occurs when waking directly from REM sleep, which is highly likely during naps longer than 45 minutes. To prevent this, the most effective step is limiting afternoon naps to 20?30 minutes so you do not enter deep sleep cycles. Additionally, maintain a consistent nighttime sleep schedule, as sleep deprivation is a major trigger, and avoid sleeping on your back. While medications like selective serotonin reuptake inhibitors (SSRIs) can suppress REM sleep and reduce episodes, they are typically reserved for severe cases. I highly recommend consulting a sleep specialist to evaluate your symptoms and rule out underlying conditions like narcolepsy.
