And that’s not just because we’re in quarantine. It’s because the spectrum of visible light we see stimulates us. And some of that is blue light. Even though blue light seems to be getting a bad rap these days, it’s actually essential for good health. The blue light we get from the sun boosts alertness, helps support memory and cognitive function, and elevates our mood. It also regulates our circadian rhythm\u2014the body’s natural wake and sleep cycle. So, exposure to blue light during the day is great.Get rid of blue light at nightWhen we have an issue with blue light is at night. How do we get blue light at night, you might ask? Our devices. Normally, the pineal gland in our brain begins to release melatonin a couple of hours before bedtime. But the pineal gland is also hooked up with our optic nerves. So, when we get blue light from our devices, that blue light tells the pineal gland not to release melatonin. That’s why watching movies on our tablet or scrolling through our phone in bed may make it harder to fall asleep and makes us wake up feeling sleepier\u2014even after eight hours of good shuteye.If you want good sleep, it\u2019s important to restrict blue light at night. And while there’s a lot of hype around blue light glasses, there\u2019s no great consensus they\u2019re helpful. It’s simple. If it\u2019s dark, the pineal gland will start to work and do its job. If you get blue light, it will shut off.How to counteract blue lightUse blackout curtains. Your room should be pitch-black dark so your pineal gland starts working, releasing the melatonin you need to sleep better. Ever notice every good hotel has blackout curtains? It’s so you sleep better.Put your laptop, tablet, phone, etc. away before you go to bed. It will take some practice, but trust me, it will be worth it.If needed consider taking a long-acting, slow-release melatonin. If the goal is to improve the release of melatonin in your body, you can take a melatonin supplement. Melatonin can also be important to help regulate time zone changes. But it\u2019s always best to take a long-acting, slow-release melatonin. If you take a short acting, it will peak and be gone. Melatonin is also a very powerful antioxidant, helping refresh the body and the immune system, so when you wake up, you feel refreshed.Supplements for your eyesIf you’re worried about eye strain on top of the blue light absorption, we know the cells in our eyes are full of long-chain healthy fat, DHA Omega-3. Taking a DHA supplement will help support the overall health of the retinal cells. Most people also don\u2019t get enough Omega-3, so Persona’s DHA supplement is a great add on for all those Omega-3 DHA fatty acids, essential for eye and brain health.","protected":false},"excerpt":{"rendered":"
