0:00.0	Welcome to this on-air with Ella minisode. A little bite-sized boost to your day. Always quick,
0:05.8	always thought-provoking, and always under 10 minutes. Let's go. Tell me, what is blue light?
0:15.3	What are we even talking about? I mean, the sun emits blue light, right? And so do light bulbs. But we are exposed to more blue light than ever, and perhaps more than we were designed to, because of the obvious widespread use of LED devices, computers and laptops, flat screen TV, cell phones, tablets.
0:36.2	They all emit high and I would say unnatural amounts
0:42.4	of blue light. Is that fair? Yeah, so let's go into this a bit deeper. So if we look at
0:46.7	380 to 450 nanometers, right, that harmful blue light is a blue light that impacts our eyes.
0:52.6	So that cumulative exposure, it causes visual stress
0:55.4	on our visual system, which leads to eye strain, fatigue and headaches. Now, blue light from
0:59.6	450 to 470 nanometers, the blue light that impacts our sleep. And that's because that blue light
1:04.8	suppresses melatonin, which is the hormone, which tells our body it's now time to go to bed, right?
1:10.3	Now, the sun, as you rightly said, is a big emitter of blue light, and it's now time to go to bed right now the sun as you rightly said is a big
1:13.2	emitter of blue light and it's probably the biggest emitter on blue light but what the problem
1:17.0	here is is we're looking at screens directly it's not indirect lighting whereas lighting around us
1:23.1	and the sunlight is indirect unless you're someone that looks right into the sun and then that's a
1:27.9	different story. But for the rest of us, you know, work from screens, that's eight hours a day,
1:34.1	you play, you connect with family or friends, you know, on a screen again, a few hours and evening,
1:40.0	we are increasing our time on screens and therefore increasing our direct exposure to blue light.
1:47.0	So that's that cumulative exposure that we should be concerned about.
1:50.4	Talk to me about what this is doing to our retinas, to our eyes.
1:56.3	Yeah, sure.
1:56.9	So, you know, there's numerous studies out there that have been done that are in vitro studies,
2:01.5	which are, you know, in the lab, looking at cells in mice or animals.
