“Hitting the snooze button is one of the worst things you can do because it prolongs morning grogginess and associates the bed with being awake,” (see article)

“...fragmented sleep can be problematic because it disrupts the natural sleep-wake cycle, leading to sleep inertia, which is the groggy and disoriented feeling experienced upon waking...” (see article)

“The more alarms you have, the harder it's going to be for you to wake up in the morning” (see article)

"Hitting snooze, especially when it’s multiple alarms in a short period of time, prevents you from re-entering a restorative sleep phase, so you’re unlikely to get more quality sleep." (see article)

“It's satisfying in the moment to hit the snooze and delay getting out of bed and starting the day, but it does actually fragment and undermine that sleep quality.” (see article)

“Hitting snooze can be harmful, because the sleep you get between alarms is usually fragmented and low-quality...which can make you feel even groggier when you finally get up" (see article)

“Using a snooze alarm prolongs sleep inertia compared to a single alarm, possibly because snooze alarms induce repeated forced awakenings.” (see article)
