How a simple shift in your morning routine can improve your sleep and energize you all day
The good news is this 'biohack' requires almost no willpower.

Going outside and facing the sun every morning can be life-changing.
Most of us have a desire to improve our health, sleep more soundly, have more energy and just generally feel better in our daily lives. And yet those things feel elusive to many of us, so we're always on the hunt for hacks that can help us—and if those hacks don't require a huge change in lifestyle or herculean feats of willpower, all the better.
Thankfully, there's one small change you can make to your morning routine that can make a big difference in how you feel, think and sleep, and it's refreshingly simple.
In a nutshell: Go outside and face the sun. More specifically, go outside as soon as possible after waking, but definitely within the hour, and look toward the sun for 2 to 10 minutes if it's a bright, sunny day and a little longer on a cloudy one.
Most of us know we get vitamin D from sun exposure on our skin, but that's really not what getting morning sunlight is about. It's about the sun's light energy hitting our eyes.
As Dr. Andrew Huberman, Stanford University neuroscience professor and opthamologist, explains, "This is not some 'woo' biological thing. This is grounded in the core of our physiology. There are literally hundreds if not thousands of quality peer-reviewed papers showing that light viewing early in the day is the most powerful stimulus for wakefulness throughout the day and it has a powerful positive impact on your ability to fall and stay asleep at night."
Huberman calls it a "power tool" for getting a great night's sleep and lists it as one of the six pillars people should invest in every day—morning sunlight, daily movement, quality nutrition, stress control, healthy relationships and deep sleep.
While the advice to look toward the sun flies in the face of all the times we've been warned not to look at the sun, in the early morning, the sun is less intense and you don't need to look directly at it to get the benefits of its light rays. The photons still enter your eyes through indirect light, triggering the cortisol spike that sets your circadian rhythm in order.
"Getting sunlight in your eyes first thing in the morning is absolutely vital to mental and physical health," Huberman says. "It is perhaps the most important thing that any and all of us can and should do in order to promote metabolic well-being, promote the positive functioning of your hormone system, get your mental health steering in the right direction."
He explains that artificial lights aren't the same and won't have the same impact. Conversely, artificial light can mess up your circadian rhythm if you look at them too late at night or when you should be sleeping.
"There's this asymmetry in our retinal, in our eye biology and our brain's biology, whereby early in the day, right around waking, you need a lot of light, a lot of photons, a lot of light energy," he says on his podcast. "And artificial lights generally won't accomplish what you need them to accomplish. But at night, even a little bit of artificial light can really mess up your so-called circadian, your 24-hour clocks, and all these mechanisms we're talking about."
The good news is that stepping out your front door and standing in the sun doesn't require a whole lot of willpower—at least not like exercise or resisting screens in the evening does. Simply go outside and stand there (though walking is even better). Give it a try and see if it makes a difference for you.
And you can also see Dr. Huberman go a lot more in depth about the benefits of sunlight and light therapies of all kinds here.

An Irish woman went to the doctor for a routine eye exam. She left with bright neon green eyes.
It's not easy seeing green.
Did she get superpowers?
Going to the eye doctor can be a hassle and a pain. It's not just the routine issues and inconveniences that come along when making a doctor appointment, but sometimes the various devices being used to check your eyes' health feel invasive and uncomfortable. But at least at the end of the appointment, most of us don't look like we're turning into The Incredible Hulk. That wasn't the case for one Irish woman.
Photographer Margerita B. Wargola was just going in for a routine eye exam at the hospital but ended up leaving with her eyes a shocking, bright neon green.
At the doctor's office, the nurse practitioner was prepping Wargola for a test with a machine that Wargola had experienced before. Before the test started, Wargola presumed the nurse had dropped some saline into her eyes, as they were feeling dry. After she blinked, everything went yellow.
Wargola and the nurse initially panicked. Neither knew what was going on as Wargola suddenly had yellow vision and radioactive-looking green eyes. After the initial shock, both realized the issue: the nurse forgot to ask Wargola to remove her contact lenses before putting contrast drops in her eyes for the exam. Wargola and the nurse quickly removed the lenses from her eyes and washed them thoroughly with saline. Fortunately, Wargola's eyes were unharmed. Unfortunately, her contacts were permanently stained and she didn't bring a spare pair.

Since she has poor vision, Wargola was forced to drive herself home after the eye exam wearing the neon-green contact lenses that make her look like a member of the Green Lantern Corps. She couldn't help but laugh at her predicament and recorded a video explaining it all on social media. Since then, her video has sparked a couple Reddit threads and collected a bunch of comments on Instagram:
“But the REAL question is: do you now have X-Ray vision?”
“You can just say you're a superhero.”
“I would make a few stops on the way home just to freak some people out!”
“I would have lived it up! Grab a coffee, do grocery shopping, walk around a shopping center.”
“This one would pair well with that girl who ate something with turmeric with her invisalign on and walked around Paris smiling at people with seemingly BRIGHT YELLOW TEETH.”
“I would save those for fancy special occasions! WOW!”
“Every time I'd stop I'd turn slowly and stare at the person in the car next to me.”
“Keep them. Tell people what to do. They’ll do your bidding.”
In a follow-up Instagram video, Wargola showed her followers that she was safe at home with normal eyes, showing that the damaged contact lenses were so stained that they turned the saline solution in her contacts case into a bright Gatorade yellow. She wasn't mad at the nurse and, in fact, plans on keeping the lenses to wear on St. Patrick's Day or some other special occasion.
While no harm was done and a good laugh was had, it's still best for doctors, nurses, and patients alike to double-check and ask or tell if contact lenses are being worn before each eye test. If not, there might be more than ultra-green eyes to worry about.
