CAN SUNLIGHT SAVE YOUR EYES? · Your Daily Dose

• 0:00
  Speaker 1: Afternoon, everybody. It is August fourteenth, twenty twenty sixth day.
• 0:04
  Speaker 1: We're going to talk about your eyes. Your eyes can
• 0:08
  Speaker 1: reveal signs of disease throughout your body. Did you know
• 0:10
  Speaker 1: that do you go more than once a year to
• 0:14
  Speaker 1: see the eye doctor. We're going to share some insight
• 0:17
  Speaker 1: with you. Stay tuned, hi, and welcome to Health Talk
• 0:20
  Speaker 1: with Doctor Lynn. Your daily dose. The information you hear
• 0:23
  Speaker 1: on the show is informational. It's not meant to diagnose
• 0:26
  Speaker 1: or treat any disease. Any kind of complete health conditions
• 0:31
  Speaker 1: must be checked out and discussed with your primary care physicians.
• 0:36
  Speaker 1: Get ready for the good news of the day. God
• 0:39
  Speaker 1: bless you, folks, and here is doctor Lynn. Our daily
• 0:43
  Speaker 1: devotional today comes from the Book of Revelation, Chapter one.
• 0:46
  Speaker 1: I am yours for all eternity. I am the Alpha,
• 0:49
  Speaker 1: the omega, the one that is, and was and is
• 0:53
  Speaker 1: to come. The world you inhabit is a place of
• 0:56
  Speaker 1: constant changes, more than your mind can absorb without going
• 0:59
  Speaker 1: into shop. Even the body you inhabit is changing relentlessly,
• 1:03
  Speaker 1: in spite of modern science's attempt to prolong youth and
• 1:06
  Speaker 1: life indefinitely, I, however, am the same yesterday and today
• 1:12
  Speaker 1: and forever. Because I never changed. Your relationship with me
• 1:15
  Speaker 1: provides a rock solid foundation for your life. I will
• 1:18
  Speaker 1: never leave your side when you move on from this
• 1:21
  Speaker 1: life to the next, My presence besides, you will shine
• 1:24
  Speaker 1: brighter with each step. You have nothing to fear because
• 1:27
  Speaker 1: I am with you for all time and throughout all eternity.
• 1:31
  Speaker 1: Stay tuned seven nine six four five to reach me
• 2:51
  Speaker 1: off air. Glenn Jeffrey has studied the human eyes for decades.
• 2:55
  Speaker 1: He has published top tier medical journals, advised governments, and
• 2:58
  Speaker 1: trained a generation of visions. Jeffrey practices what he preaches.
• 3:03
  Speaker 1: He even commutes to work by bike because of what
• 3:07
  Speaker 1: sunlight does for his retina. Wait a minute, I thought
• 3:11
  Speaker 1: we were supposed to wear dark glasses in the sun. Jeffrey,
• 3:15
  Speaker 1: and neuroscience professor at the University College London, has discovered
• 3:19
  Speaker 1: that brief daily exposure to daylight as little as thirty
• 3:23
  Speaker 1: minutes is one of the most powerful habits for long
• 3:26
  Speaker 1: term eye health at any age. Without a doubt, the
• 3:30
  Speaker 1: best kind of light for your vision is daylight. Most
• 3:35
  Speaker 1: of us are starved of one critical component of natural light,
• 3:38
  Speaker 1: infrared wavelengths. Two factors are driving this deficit. We spend
• 3:43
  Speaker 1: far less time outdoors, and most indoor lights are light
• 3:46
  Speaker 1: emitting diodes or LED bulbs designed for energy efficacy, not
• 3:51
  Speaker 1: eye health. They admit visible light but strip out infrared
• 3:54
  Speaker 1: almost entirely. Infrared light does something no other wavelength does effectively.
• 4:00
  Speaker 1: It penetrates the skin and boosts mitochondrial functioning, which in
• 4:04
  Speaker 1: turn increases energy. A dentisen triphosphate production ATP in the eye.
• 4:11
  Speaker 1: ATP helps to regulate eye pressure, maintain your lenses, protect
• 4:15
  Speaker 1: against retinal cell damage, and downstream effect is meaningful protection
• 4:19
  Speaker 1: against galla coma, cataracts, and macular degeneration. The retina contains
• 4:24
  Speaker 1: exceptionally dense packed mitochondria in a high metabolic rate, which
• 4:29
  Speaker 1: makes it particularly prone to decline with age. Infrared wavelengths
• 4:32
  Speaker 1: can help to recharge it. One of Jeffrey's studies, published
• 4:36
  Speaker 1: in the Science Tific Reports, found that infrared lighte applied
• 4:40
  Speaker 1: for fifteen minutes to the chest, even when specifically not
• 4:43
  Speaker 1: allowed into the eyes, significantly improved kellor contrast sensitivity. Kellor
• 4:50
  Speaker 1: contrast sensitivity, a measure of the retinal function that's nearly
• 4:54
  Speaker 1: as important as visual acuity, allows us to distinguish objects
• 4:58
  Speaker 1: from the background to help us with driving, reading, and
• 5:01
  Speaker 1: other daily activities. In a follow up study, office workers
• 5:06
  Speaker 1: were given broad spectrum incandescent lamps that included infrare delight
• 5:10
  Speaker 1: and showed significant improvement in Kellor contrast sensitivity that lasted
• 5:14
  Speaker 1: two months. Researchers believe light improves mitochondric performance as measured
• 5:20
  Speaker 1: through Keller contrast sensitivity, and in fact, a simple and
• 5:24
  Speaker 1: highly economical intervention such as using a small incandescent lamp nearby,
• 5:32
  Speaker 1: could dramatically mitigate age related to clines in ATP production.
• 5:38
  Speaker 1: It can make it sound really impressive and high tech,
• 5:41
  Speaker 1: but it's not, Jeffrey said. Jeffrey studies on the superiority
• 5:46
  Speaker 1: of incandescent lighting over led or a nod to the
• 5:49
  Speaker 1: original light source, the sun. Incandescent light has the same
• 5:53
  Speaker 1: wavelength as sunlight, but sunlight has a greater intensity and
• 5:57
  Speaker 1: balance even on cloudy days. It more powerful even when
• 6:01
  Speaker 1: it seems to be barely there. The journey to better
• 6:04
  Speaker 1: site with sunlight beginning childhood. With the prevention of myopia
• 6:08
  Speaker 1: or near sightedness more than just an opt out of
• 6:11
  Speaker 1: proportion refractive air. Myopia is a medical condition that increases
• 6:16
  Speaker 1: the lifetime risk of complications such as retinal detachment or glaucoma.
• 6:21
  Speaker 1: Sunlight is the primary strategy to avoid myopia, and it's
• 6:24
  Speaker 1: powerful enough to mitigate cases of strong genetics. According to Dawn,
• 6:29
  Speaker 1: beauty and optometry professor at Ohio State, children with two
• 6:35
  Speaker 1: near sighted parents have about a sixty percent chance of
• 6:38
  Speaker 1: also being near sighted. Spending fourteen hours a week outside, however,
• 6:42
  Speaker 1: can cut their risk to twenty percent from sixty. Sunlight
• 6:46
  Speaker 1: exposure can't stop myopia that's already developing in children. The
• 6:50
  Speaker 1: mechanism appears to involve dopamine. Right light triggers the release
• 6:54
  Speaker 1: of dopamine for retinal cells, which is believed to stop
• 6:57
  Speaker 1: the eyeball from growing too long. Forty percent of Americans
• 7:01
  Speaker 1: have myopia, a number rising rapidly. I would put the
• 7:06
  Speaker 1: blame on being indoors, which is just more fun than
• 7:08
  Speaker 1: it ever used to be with screens and video games
• 7:10
  Speaker 1: and entertainment officers. But we don't rely on infrared lights
• 7:15
  Speaker 1: to fulfill our goal of more light. Most of what
• 7:17
  Speaker 1: he's reviewed is far more powerful. Energy levels vary widely
• 7:21
  Speaker 1: across products, so exposure time matters, but there's little regulation.
• 7:26
  Speaker 1: Manufacturers chase what selves stronger, brighter, more intense, even if
• 7:30
  Speaker 1: the research hasn't caught up. Bottom line practical implications more
• 7:35
  Speaker 1: manageable than they might see. Outdoors, you don't need direct
• 7:38
  Speaker 1: sun exposure. You could still protect your eyes from ultraviolet
• 7:41
  Speaker 1: light by wearing sunglasses or a hat, or by sitting
• 7:44
  Speaker 1: in the shade. Jeffrey current recommendations at least thirty minutes
• 7:48
  Speaker 1: of outdoor time daily, though the guidance would evolve as
• 7:52
  Speaker 1: researchers accelerate. If you're inside, Jeffrey recommends adding a single
• 7:56
  Speaker 1: incandescent or halogen bulb, both of which include infrared wavelengths,
• 8:01
  Speaker 1: in an area of home where you spend time in
• 8:03
  Speaker 1: the morning. Morning light exposure is best, he said, whether
• 8:07
  Speaker 1: outdoor or with artificial lights, because your mitochondrier are more
• 8:10
  Speaker 1: sensitive right after waking. Jeffrey's hoping to change conventional thinking
• 8:16
  Speaker 1: and laws that limit in cadescent light by sharing his
• 8:18
  Speaker 1: research on human health with policymakers and leaders in the
• 8:22
  Speaker 1: architecture industry. I'm not saying that it's got a lot
• 8:25
  Speaker 1: to do with light, but I think we should start
• 8:26
  Speaker 1: paying attention to light now. You want to accentuate things
• 8:31
  Speaker 1: even more. Nutritional Frontiers has a product called twenty twenty
• 8:35
  Speaker 1: which is amazingly powerful for protecting the workings of the
• 8:38
  Speaker 1: eyes A simple once a day check it out at

• 8:46
  Speaker 1: for the day.
