Why Daylight Saving Time Is Bad For You

According to Popular Science –

The annual switch to daylight saving time (DST) is the hour that launched a thousand angry articles. And honestly, this is one of the few events that actually warrants them. DST, in addition to not actually being invented by America’s favorite founding father Benjamin Franklin, is mostly a terrible idea.

Glow – A Light That Seems To Be A Bright Idea

According to TechCrunch –

The basic use of the Glow is pretty straightforward. You turn it on by flipping it over, and it fills your room with warm LED light. The light then dims to darkness over a 45-minute period — as Chief Product Officer Jeff Chapin put it, it’s “mimicking the setting of the sun and it helps you get sleepier as it dims into lower and lower amplitudes.”

How Do Dolphins Sleep Without Drowning?

Bottlenose-sAccording to Mental_floss –

First of all, dolphins don’t sleep in one long chunk like humans or other mammals. Instead, they take 15 to 20 minute naps throughout the day and night. But the biggest factor in dolphin sleep is their brain doesn’t rest all at once like humans’ do. “Scientists have discovered that instead of ‘falling asleep’ and entering an unconscious state like humans, a dolphin rests one hemisphere of its brain at a time,” Belden explains. “So while one hemisphere is resting, the other is still active so that the dolphin can be sure to open its blowhole above the water.” Whichever brain hemisphere is active, the opposite eye will remain open. This is good for both swimming to the surface to breathe and for keeping a look out for predators. As Belden puts it, “Dolphins literally sleep with one eye open.” It’s impossible to know what sleeping with just half your brain at a time would feel like, and dolphins can’t exactly explain it to us. But Belden says that scientists speculate it might be sort of like daydreaming or meditating.

Seems quite reasonable. I know several people who can spend the entire day in such a state.

Night Owls Are Smarter – This Explains A Lot

The Winnipeg FreePress reported –

People with higher IQ’s are more apt to be nocturnal night-owls. Those with lower IQ’s tend to restrict their activities primarily to daytime. People who prefer to go to bed early, and who are early-risers, demonstrate “morningness,” whereas those whose sleep patterns are shifted later demonstrate “eveningness.” Researchers say eveningness tends to be a characteristic of those with higher IQ’s. According to Kanazawa, ancestral humans were typically diurnal, and that a shift towards more nocturnal activities is an “evolutionarily novel preference” of the type normally found in more intelligent individuals, demonstrating “a higher level of cognitive complexity” in the practitioners.
