A new scientific study confirms what we should all already know.

A while ago, science revealed that the ultimate key to blissful and happy relationships is getting more sleep, probably because we’re all assholes when we’re tired.

And now, a brand spanking new study suggests the secret to an amazing night’s sleep is mind-blowing sex, meaning sex and sleep totally go hand-in-hand, and are basically the answers to all of our problems.

For the study, Australian sleep researcher Dr. Michele Lastella surveyed 460 participants between the ages of 18 and 70, and found that people who indulged in a little nocturnal nookie slept waaay better than those who kept it in their pants.

“What we found was 64 percent of our respondents indicated they slept better when sex was with a partner and it involves an orgasm,” he told Adelaide Now.

“There’s strong evidence to suggest substituting screen time for play time,” he added, encouraging everyone to put their phones and laptops away, and get frisky.

“When you’re engaging in sex, you’re not thinking about what to do the next day, you’re not going through your phones. It distracts you.”

So distracted.

Moreover, a similar study from Oxford Economics and the National Centre for Social Research discovered that the ultimate equation for true happiness is sex + sleep, so it would appear that in order to live a pleasurable and fulfilling life, you should have sex every night, and then drift off to the land of golden slumbers for a solid eight hours.

For the study, researchers used the Living Well Index to survey 8,250 participants on their lives and emotional fulfillment, and found that the happiest people were those who spend lots of time in bed, both sleeping and bumping uglies.

“Sleep was the strongest indicator of a broader sense of well being, controlling for other factors. The majority of those with the highest Living Well scores reported feeling well rested most of the time (60 percent), whilst over half of those in the bottom 20 percent of the Index said that they rarely, or never, felt well rested,” the authors wrote.

“Across the population as a whole, just over a third (35 percent) said they were fairly or very satisfied with their sex lives. Once again, these individuals were disproportionately likely to be found at the top of the Living Well Index – with almost two thirds (63 percent) of those at the top saying that they were satisfied with their sex life, twice the national average.”

Well, now that you know this valuable information, I highly recommend applying it to your own life, because having sex, sleeping, then waking up happy is a pretty stellar deal.
