25 Napping Facts Every College Student Should Know

1. It makes you smarter
   According to Dr. Matthew Walker of the University of California, napping for as little as one hour resets your short-term memory and helps you learn facts more easily after you wake up.
2. Abandon all-nighters
   Foregoing sleep by cramming all night reduces your ability to retain information by up to 40%. If you can, mix in a nap somewhere to refresh your hippocampus.
3. It doesn’t mean what you think
   If you know you have to pull an all-nighter, try a “prophylactic nap.” It’s a short nap in advance of expected sleep deprivation that will help you stay alert for up to 10 hours afterwards.
4. You can’t avoid that down period after lunch by not eating
   Human bodies naturally go through two phases of deep tiredness, one between 2-4 a.m. and between 1-3 p.m. Skipping lunch won’t help this period of diminished alertness and coordination.
5. Pick the right time
   After lunch in the early afternoon your body naturally gets tired. This is the best time to take a brief nap, as it’s early enough to not mess with your nighttime sleep.
6. Hour naps are great
   A 60-minute nap improves alertness for 10 hours, although with naps over 45 minutes you risk what’s known as “sleep inertia,” that groggy feeling that may last for half an hour or more.
7. But short naps are best
   For healthy young adults, naps as short as 20, 10, or even 2 minutes can be all you need to get the mental benefits of sleep, without risking grogginess.
8. Drink coffee first
   The way this works is you drink a cup of coffee right before taking your 20-minute or half-hour nap, which is precisely how long caffeine takes to kick in. That way when you wake up, you’re not only refreshed, but ready to go.
9. The NASA nap
   A little group called NASA discovered that just a 26-minute nap increases performance by 34% and alertness by 54%. Pilots take advantage of NASA naps while planes are on autopilot.
10. Can’t sleep? Don’t stress
    Even if you can’t fall asleep for a nap, just laying down and resting has benefits. Studies have found resting results in lowered blood pressure, which even some college kids have to worry about if they are genetically predisposed to high blood pressure.
11. Napping may save your life
    A multi-year Greek study found napping at least three times per week for at least 30 minutes resulted in a 37% lower death rate due to heart problems.
12. More nap benefits for the brain
    Not only will napping improve your alertness, it will also help your decision-making, creativity, and sensory perception.
13. But wait, there’s more
    Studies have found napping raises your stamina 11%, increases ability to stay asleep all night by 12%, and lowers the time required to fall asleep by 14%.
14. The ultimate nap
    According to Dr. Sara Mednick, the best nap occurs when REM sleep is in proportion to slow-wave sleep. Use her patented Take A Nap Nap Wheel to calculate what time of day you can nap to the max.
15. Fight the Freshman 15
    Research shows that women who sleep five hours at night are 32% more likely to experience major weight gain than those sleeping seven hours. A two-hour nap isn’t feasible for many, but napping is a good way to make up for at least some lost night sleep.
16. If it was good enough for them…
    Presidents JFK and Bill Clinton used to nap every day to help ease the heavy burden of ruling the free world. Of course, they also had other relaxation methods, but we won’t get into those.
17. Do like the Romans do
    In ancient Rome, everyone, including children, retreated for a 2 or 3-hour nap after lunch. No doubt this is the reason the Roman empire lasted over 1,000 years
18. Don’t wait too long
    The latest you want to wake up from a nap is five hours before bedtime, otherwise you risk not being able to fall asleep at night.
19. Sugar is not a good substitute for a nap
    When we are tired, we instinctively reach for foods with a high glycemic index, but after the initial energy wears off, we’re left more tired than we were before.
20. It’s a good way to catch up
    If it takes you less than five minutes to fall asleep at night, you are sleep deprived. If you never can seem to get to bed earlier at night, a mid-day nap is a great way to catch up on sleep.
21. Underclassmen need more sleep
    Freshmen and sophomores who are still in your teens: you need up to 10 hours of sleep to feel rested. So odds are, you are sleep-deprived.
22. You’ll have to leave the party sooner
    After one school-week of not getting enough sleep, three alcoholic drinks will affect you the same way six would when you are fully rested.
23. Don’t drive drowsy
    Don’t be afraid to take advantage of an “emergency nap” on the side of the road in your car. Every year, as many as 100,000 traffic fatalities are caused by sleepy people behind the wheel.
24. The Einstein Method
    If you are concerned about sleeping too long, do what Albert Einstein regularly did: hold a pencil while you’re drifting off, so when you fall asleep, the pencil dropping will wake you up. (We do not guarantee you will wake up with a 180 IQ.)
25. Missing sleep is worse at your age
    For people ages 18 to 24, sleep deprivation impairs performance more significantly than in other age brackets.

Reblogging this for my college friends because I care about you guys! <3 Haha.

I need to get 10 hours of sleep because I’m a teenager? no wonder I’m always tired. 

Reblogging for future reference.

I tried to tell my mom that I wasn’t weird for taking afternoon naps after school everyday…..

A Diamond in the Flame

The candle was invented over 2,000 years ago in China, but for a long time no one quite understood what secrets the flames held—scientists knew that hydrocarbon molecules exist at the base of the flame, and are converted into carbon dioxide by the time they reach the top, but they didn’t understand the exact process. ‘You have the glittering beauty of gold and silver, and the still higher lustre of jewels, like the ruby and diamond,’ Michael Faraday wrote in 1860, addressing light, ‘but none of these rival the brilliancy and beauty of flame. What diamond can shine like flame?’ Well, according to research at the University of St Andrews, a flame actually shines like a diamond. Professor of Chemistry Wuzong Zhou recently discovered that a burning candle flame creates diamond nanoparticles at a rate of 1.5 million per second. Dr Zhou used a sampling technique he invented himself to remove particles from the centre of the flame, and upon analysis, he found the flame contained all four known forms of carbons. This was strange, since each of them are usually created under different conditions, but he realised this meant something amazing: the hydrocarbon molecules were being turned into tiny diamonds. The diamonds burn up in the process and are released as carbon dioxide, and there are currently no ways to extract them, but Zhou’s research could prove useful for future research into green, economic diamond production. It’s a tantalising discovery—light a candle, and you can watch millions and millions of tiny, glittering diamonds wink in and out of existence.

Space Shot of the Day: Cathedral to Massive Stars

The Hubble Space Telescope took this spellbinding image of Pismis 24 (shown center above), one of the most massive and luminous star clusters known, glimmering above the NGC 6357 nebula that is approximately 8150 light-years away. According to NASA’s estimates, the brightest star of Pismis 24 cluster is over 200 times the mass of our Sun.

Space Shot of the Day is a feature series following the latest developments in planetary science, astrophotography, space exploration, future plans for colonization and all things related to outer space.

StarTalk is awesome and this is brilliant.
