Why can't you take a nap right now?
And even if you can, "Naps throw off the sleep cycle", not everyone finds them worthwhile.
1. I have things to do.
2. Naps throw off my sleep cycle
3. 6 hours isn't the end of the world.
The self-care advice on this website is bullshit.
Psychorigid and neurotic attitudes towards sleep do not promote good sleep. You can not "catch up" on lost sleep by napping. Instead, you risk throwing off your sleep for that night and perpetuating a pattern of sleeplessness. Afternoon naps are bad sleep hygiene. They are something you unlearn in treatment for insomnia and many other sleep disorders.
