Bedtime stacking is linked to disrupted sleep and morning burnout, experts say

Experts describe 'bedtime stacking'—doing tasks from bed before sleep—as a growing Gen Z trend that can weaken the bed-sleep association, delay sleep onset, and contribute to night awakenings and worsened insomnia for some people.

Bedtime stacking has become a popular trend on social platforms, especially among Gen Z, and refers to completing tasks from the comfort of bed before trying to sleep. Sleep doctors and psychologists report concern that this habit can change how the brain associates bed with sleep and can delay usual bedtimes. Clinicians also note links between the practice and more frequent night awakenings, including reports of 3 a.m. wakeups. Several experts described short limits and low-stimulation choices as ways clinicians discuss the practice, rather than long nightly multitasking. Key points about bedtime stacking: - Definition: Bedtime stacking describes turning the bed into a multifunctional command center for activities such as work, snacking, watching shows, or planning, rather than using it only for sleep. - Effect on bedtime: Experts say the habit can delay usual sleep times and reduce the bed's association with rest, making it harder for the brain to switch off. - Night awakenings and insomnia: Clinicians report that heightened cognitive or emotional arousal and elevated baseline stress hormones can be associated with night awakenings and may worsen insomnia in vulnerable people. - Clinician observations: Reported recommendations from clinicians include favoring lower-stimulation activities if done occasionally, setting limits on the duration of in-bed activities, and avoiding making the practice nightly. Summary: Experts warn the trend of bedtime stacking may increase sleep disruption for some individuals by changing how the bed is used and by prolonging cognitive stimulation before sleep. Clinicians discussed limits and lower-stimulation choices as ways they frame the practice; longer-term effects of the trend on population sleep health are undetermined at this time.
