I remember reading a manga about some girl that really enjoyed sleeping. There was a chapter where some guy (maybe her brother?) was studying and falling asleep, so she suggested that he take a nap. She then explained the benefits of taking a short nap?

Sounds like it might be Saeki-san wa Nemutteru

Saeki-san is cute but not the one I'm looking for. Thank you for the recommendation :)
