Sleep Cycle Alarm Clock

Here is a pretty sweet alarm app for the iPhone.  You place the phone in your bed and set a time range in which you would like to be woken up.  Once you've done that you place the phone in your bed.

Now here is the cool part.  When you sleep, your body passes through various stages or cycles.  When you wake up durring a cycle of deep sleep, you will feel less rested. The phone measures your movements in bed and from there determines which sleep cycle you are experiencing.  It then will wake you up during the preset window but will do it at the time you are likely to feel most rested.  While measuring sleep cycles with precision is much more complicated, this is the first time people have been able to purchase such technology for 99 cents.

Bed for Dreams

If your looking for a place to have sweet dreams, I can't think of a better one than this bed designed by Joseph Walsh... Unless of course you've consumed a lot of caffeine to block the [Sleepy Parts of Your Brain].

What Caffeine Actually Does to Your Brain

The following is an excerpt taken from a post at Lifehacker.  The full article can be read here.

Caffeine Doesn't Actually Get You Wired

Right off the bat, it's worth stating again: the human brain, and caffeine, are nowhere near totally understood and easily explained by modern science. That said, there is a consensus on how a compound found all over nature, caffeine, affects the mind.

Every moment that you're awake, the neurons in your brain are firing away. As those neurons fire, they produce adenosine as a byproduct, but adenosine is far from excrement. Your nervous system is actively monitoring adenosine levels through [Sleepy Parts]. Normally, when adenosine levels reach a certain point in the [sleepy parts of your] brain and spinal cord, your body will start nudging you toward sleep, or at least taking it easy. There are actually a few different [Sleepy Parts] throughout the body, but the one caffeine seems to interact with most directly is the A1 [Sleepy Part]. More on that later.

Enter caffeine. It occurs in all kinds of plants, and chemical relatives of caffeine are found in your own body. But taken in substantial amounts—the semi-standard 100mg that comes from a strong eight-ounce coffee, for instance—it functions as a supremely talented adenosine impersonator. It heads right for the [Sleepy Parts] in your system and, because of its similarities to adenosine, it's accepted by your body as the real thing and gets into the receptors.
