It should go without saying, but healthier = more dateable.
When you sleep, your brain and body get to recover from a hard day's work. Not getting enough snooze time will leave you cranky, irritable, and will totally mess with your grip on reality. You can bet this BS is going to impact your romantic relationships. No one wants to date a miserable, tired mess.
Which brings me to my next point!
No sleep means no sex
That's right. If you aren't getting enough sleep, your sex life will suffer dramatically. It's not just your cranky attitude that will put your partner off of doing the no-no-cha-cha -- a lack of sleep can also mess up your ability to, well, get it up.
"Poor sleep quantity and quality decreases our ability to recognize other people's emotions, decreases our ability to deal with stress, increases our anxiety, and decreases our sex drive," Dr. Oexman says.
