How smartphone light affects your brain and body

How smartphone light affects your brain and body

It may be hard to stop, but looking at your phone at night is a terrible idea.
Smartphone screens emit bright blue light so you can see them even at the sunniest times of day.
But at night, your brain gets confused by that light, as it mimics the brightness of the sun. This causes the brain to stop producing melatonin, a hormone that gives your body the "time to sleep" cues. Because of this, smartphone light can disrupt your sleep cycle, making it harder to fall and stay asleep — and potentially causing serious health problems along the way.
Here's how it works:

Why I Wake Up Early (And 9 Reasons You Should Do So Too)

Here are 9 reasons why I say this: 1. Get a head start When you wake up at 5am, you start your day earlier than 99.9% of the world — hence giving you a head start in your day. This creates a feel-good factor, which, while psychological, creates a host of positive effects (especially for reasons #2 and #3 in the list). After all, a good start is half the battle won. It will motivate you to stay ahead so you can maintain or even widen the lead. For example, my modus operandi when I wake up early is to work on the high-impact tasks right away, as opposed to the small, easy but unimportant tasks. I will also think and work effectively, and strive to end my day earlier so that I can have an early sleep, wake up early the next day, and continue my “head start.” On the whole, I’d say that I’m more forward thinking and proactive in managing my tasks — since I have a head start in my day, I naturally think about how I can be ahead in my work too. On the other hand, when I wake up ...

NASA unveils seasonal dust storm pattern on Mars Improving the ability to predict large-scale, potentially hazardous dust storms on Mars would have safety benefits for planning robotic and human missions to the planet's surface. NASA's Mars orbiters have unveiled a pattern of large regional dust storms occurring at about the same times each year, an advance that may help predict these hazardous events during future robotic and human missions to the red planet. After decades of research to discern seasonal patterns in Martian dust storms from images showing the dust, but the clearest pattern appears to be captured by measuring the temperature of the red planet's atmosphere. For six recent Martian years, temperature records from NASA Mars orbiters reveal a pattern of three types of large regional dust storms occurring in sequence at about the same times each year during the southern hemisphere spring and summer. Each Martian year lasts about two Ea...
