Why Can't I Sleep In On Weekends Anymore?

Sleeping in is one of the best parts of the weekend. After a long, exhausting work week, sometimes all you want to do is sleep. On Friday night, you slide under the covers, smiling in anticipation. Now you can finally catch up on your sleep.

Except you can’t. When you open your eyes Saturday morning, it’s still early. If this were a weekday, you’d be up before your alarm. So what’s the deal? 

We hate to break it to you, but you’ve pretty much done this to yourself. Your body is very good at recognizing patterns and adjusting accordingly. If you’ve got a 9-to-5 job, you’re getting up early five days a week. This effectively sets your body clock to wake you at a certain time each day.

Waking up may feel instantaneous, but it’s actually a pretty gradual process. About an hour before you wake, your blood pressure and body temperature rise, as do levels of stress hormones like cortisol. Minute by minute, you become more alert until you’re completely awake. You can shut off your alarm clock, but your body clock will just keep ticking.

There’s another reason that you probably don’t want to think about: You’re just not as young as you used to be. We need less sleep as we get older. Babies need between 16 and 20 hours. Teenagers should (but often don’t) get nine hours a night. Younger and middle-aged adults need about eight hours of sleep a night. In general, the older you get, the harder it is to snooze the day away. 

Even if you do manage to sleep in, you may never fully catch up on your sleep. If your body needs eight hours every night and you only get six or seven from Monday to Friday, you’d have to sleep an extra five to ten hours on Saturday to make it up. And experts say even that may not be enough

The bottom line: Sleep when you can, and enjoy those extra weekend morning hours. Who doesn’t want a longer weekend?

Why Do Female Spotted Hyenas Give Birth Through Their Pseudo-Penises?

At the zoo, you can sometimes tell the difference between male and female animals by noting their physical size, their behavior, and yes, their nether regions. Hyenas, however, flip the script: Not only are lady spotted hyenas bigger and meaner than their male counterparts, ruling the pack with an iron paw, they also sport what appear to be penises—shaft, scrotum, and all.

"Appear" is the key word here: These 7-inch-long phalluses don't produce sperm, so they're technically really long clitorises in disguise. But why do female hyenas have them? And do they actually have to (gulp) give birth through them? Wouldn't that hurt … a lot?

The short answers to these questions are, respectively, "We don't know," "Yes," and "OW." Longer answers can be found in this MinuteEarth video, which provides the full lowdown on hyena sex. Don't say we didn't warn you.

Are Sex, Drugs, and Rock 'n' Roll Really Linked? Researchers Investigate

Around the world, sex, drugs, and rock 'n' roll are said to go hand-in-hand. But do they? As PsyPost reports, a pair of Pennsylvania psychologists recently dove into the empirical evidence tying the three together, asking college students to talk about their drug use, sex lives, and music preferences and talents to suss out whether people who play and enjoy rock music really do have more active sex lives and drug use.

Published in the journal Human Ethnology Bulletin, the study [PDF] of 467 students relied on self-reporting, which isn't typically the most reliable evidence—people are wont to exaggerate how often they've had sex, for instance—but the survey also asked them about their desires, posing questions like "If you could, how frequently would you have sex?" It also asked about how often the students drank and what drugs they had tried in their lifetimes. They also described their musical experience and what kind of music they listened to.

The results were mixed, but the researchers identified a relationship between liking faster, "harder" music and having more sex and doing more drugs. Acoustic indie rock aficionados weren't getting quite as wild as heavy metal fans. High-tempo-music lovers were more likely to have taken hallucinogenic drugs like LSD, for example, and tended to have had more sexual partners in the previous year than people who favored slower types of music. According to the study, previous research has found that attention-seeking people are more likely to enjoy "hard" music.

The study didn't have a diverse enough group either in age or in ethnicity to really begin to make sweeping generalizations about humans, especially since college students (the participants were between 18 and 25) tend to engage in more risky behaviors in general. But this could lay the groundwork for future research into the topic. Until then, it might be more accurate to change the phrase to "sex, drugs, and heavy metal."
