Yes, that's a real terminology. As true as it gets. Believe it or not, most of us have been doing it on a frequent basis without realizing the truth behind the term.
What is it?
In simpler words, revenge bedtime procrastination is sort of a "me time" moment, where you squeeze in a bit of entertainment or relaxation before going to bed.
This often happens when you spend a bulk of your daytime immersed in work (or even parenting). So when the work is done and kids are finally asleep, that's when you indulge in personal relaxation (this usually involves being on your phone or tablet).
The thing about this habit is that you can spend up to a few hours doing this, disturbing your sleep cycle. So when your bedtime is delayed, that's when sleep deprivation kicks in.
How to Opt For A Better Relaxation Method?
Gradually reduce the duration you spend on your phone. Instead, read a book or meditate as a way to ease yourself into sleeping.
While this may be hard at first, you'll thank yourself later once you notice how improved your mood, energy and productivity are.
