The Apple Watch and Microsoft Band use optical sensors to measure heart rate. The Jawbone Up3.

You can focus on things that are barriers or you can focus on scaling the wall or redefining the problem. Steve Jobs

The Apple Watch and Microsoft Band use optical sensors to measure heart rate. The Jawbone Up3, which instead tracks your resting heart rate,  uses bioimpedance sensors and several electrodes to measure your skin’s resistance to a small amount of electrical current.

Chasing the blonde dragon is still a genuine plight, because the grass is always. There’s a misguided notion that natural beauty products just don’t do the job as well as conventional creams and cleansers. While that may be the case for some, i’ve found that many natural products are even better than the drugstore brands.

You’re just about ready to drift off, and suddenly the air conditioner kicks on. Or a car alarm screeches through the night air. Or your partner sneezes. Suddenly, you’re wide-awake again. Your brain responds to noises when you’re awake and asleep. But if the interruptions wake you up, that can keep you from getting the restful shuteye that you need.

When ambient noise is disrupting your sleep, white (or pink) noise can help to smooth out the rough edges. Imagine sitting next to a person who is loudly chewing gum in a library. Then imagine sitting next to that same person in a crowded bar. It’s the same chomping gum, but underneath the drone of a crowded place, you can’t even hear it anymore. White noise, whether it’s from a sound machine, a simple fan, or crowd noise helps to mask noise-related disruptions by creating a constant ambient sound that makes a “peak” noise, like a door slamming, less of a contrast. And that makes you less likely to be startled awake.
