Do you know what a sleeping great white shark looks like? It’s never been seen before. Until now. A robotic submersible captured the first-ever footage of a great white taking a nap, and you can see it innocently catch some zzzs with its mouth hanging wide open. It looks maybe seven percent less frightening than a great white that’s awake.
One of the best approaches I have seen for achieving a dream is to focus on being 1 percent better.
It’s no secret that adults aren’t getting enough sleep, and that’s a problem since more research is confirming that poor sleep can have lasting effects on health, including things like obesity and heart disease.
When you’re counting sheep jumping over a fence to help you fall asleep, you’re inevitably going to leave some behind. You can’t count them all! You need to sleep! But those poor imaginary leftover sheep never get to clear the fence and be free. What will happen to them? Katelyn Hagen shows the plight of the sheep never counted in this short animation, which imagines what lengths they might go to jump the line.
As a college professor, I am regularly surrounded by sleep-deprived young adults who sometimes wear their chronic lack of sleep as a badge of honor, comparing notes on who got less shut-eye before a big exam.
The brain is by far our most precious organ–others are good, too, but they all pale in comparison to the mighty brain. Because the brain works so hard around the clock (even while we’re sleeping), it uses an extraordinary amount of energy, and requires a certain amount of nutritional support to keep it going. It’s high-maintenance, in other words. But there may be misconceptions about what keeps a brain healthy–for instance, there’s little evidence that omega-3 supplements or green smoothies would do anything above and beyond generally good nutrition. So what does science actually tell us can help our brains? Here’s what we know as of now.
