Bedtime procrastination is the act of delaying getting into bed. While-in-bed procrastination is when someone is already in bed, but delays the act of sleeping. The latter is often associated with rising rates of electronic device use in bed. Insufficient sleep degrades thinking, memory, and decision-making. It leads to less productive days due to daytime sleepiness. A lack of sleep has also been linked to mental health disorders including depression and anxiety.
