This is the most common cause of a miserable sex life

If you see more starfish in bed than you like and you want to feel dizzy again from a wild sex party; a dull sex life can have a clear cause.

If the passion is nowhere to be found and you yourself are absolutely not up for any action in the bedroom, it could be due to your sleep pattern. Because what turns out? Women who sleep less than 7 hours and 22 minutes have, on average, a lot less desire for a bit of fiddling and messing around the next day. You really don't have to sleep in until lunch break to boost your sex life. No, an extra hour of sleep does the trick for many. Then the chance that you'll get lucky suddenly increases by 14 percent (compared to when you sleep less than those 7 hours and 22 minutes). In short: dive into that bed a bit earlier, sleep an hour longer on the weekend, and lo and behold, you'll see it. Suddenly, you'll be in the mood without any problem.

If you sleep longer sleep, you feel rested. Yeah, that's logical. But that's not only good for your mood and your body, but also for your self-confidence. Women find themselves a lot prettier after a good night's sleep. The same goes for men: men who sleep poorly may produce up to 15 percent less testosterone than men who are snoring away in dreamland. So yes, they also do well to get that rest. Otherwise, they don't feel like a real man, so to speak.

Ah, now that it's already getting dark around half past three in the afternoon, it's no problemo to dive into that bed. No time for sports, dinners, drinks, and overtime, no. You must sleep. You're welcome.

FACTS

• Giraffes nap the shortest of all animals: just 1.9 hours per day. A 5-minute nap already perks them up. Koalas sleep the most in the animal kingdom: up to 22 hours a day.
• Men dream 70 percent of the time about other men.
