Take a Coffee Nap: It's Better than a Coffee or a Nap Alone
If you're feeling a bit sleepy, a coffee nap could be just the thing. Half coffee, half nap, having a caffeine drink just before a nap gives you a little shuteye followed by the full benefits of caffeine.
If you're feeling a bit sleepy, a coffee nap could be just the thing. Half coffee, half nap, having a caffeine drink just before a nap gives you a little shuteye followed by the full benefits of caffeine. By happy coincidence, the amount of time it takes caffeine to affect the brain--about 20 minutes--makes for a nap that recharges your batteries without carrying you over into deep sleep, risking grogginess as a result of what scientists call "sleep inertia".
Studies in the UK and Japan have found that individuals who take a coffee nap perform better on cognitive exercises and memory tests than those who take naps or drink caffeine alone. Recent advances in neuroscience help explain why. When caffeine hits the brain, it competes for space on neuro-receptors with similarly-shaped molecules called adenosine. A byproduct of brain activity, adenosine accumulates throughout the day and eventually makes you feel tired. Thus taking a nap can clear receptors of some adenosine, preparing the way for a fuller caffeine effect.
Because there is a small window of time to rest during coffee naps, concentrated caffeine is recommended, such as espresso or iced coffee. And despite decades of attempts to find something inherently bad about caffeine, humans metabolize it such that, for adults, there are no real problems, says NYU professor of nutrition Marion Nestle:

For Damien Echols, tattoos are part of his existential armor.
- In prison Damien Echols was known by his number SK931, not his name, and had his hair sheared off. Stripped of his identity, the only thing he had left was his skin.
- This is why he began tattooing things that are meaningful to him — to carry a "suit of armor" made up the images of the people and things that have significance to him, from his friends to talismans.
- Echols believes that all places are imbued with divinity: "If you interact with New York City as if there's an intelligence behind... then it will behave towards you the same way.".
She met mere mortals with and without the Vatican's approval.
- For centuries, the Virgin Mary has appeared to the faithful, requesting devotion and promising comfort.
- These maps show the geography of Marian apparitions – the handful approved by the Vatican, and many others.
- Historically, Europe is where most apparitions have been reported, but the U.S. is pretty fertile ground too.
Even some teachers suffer from anxiety about math.
I teach people how to teach math, and I've been working in this field for 30 years. Across those decades, I've met many people who suffer from varying degrees of math trauma – a form of debilitating mental shutdown when it comes to doing mathematics.
