Sunlight Is Important for the Prevention of Blindness

When Sunlight enters our eyes, it not only goes to your visual centers enabling you to see, it also goes to your brain’s hypothalamus where it impacts the entire body.

The hypothalamus controls body temperature, hunger and thirst, water balance and blood pressure. It also controls the body’s master gland, the pituitary, which secretes many essential hormones, including those that influence your mood.

Our body clock  is also housed in tiny centers located in the hypothalamus, controlling thee body’s circadian rhythm. This light-sensitive rhythm is dependent on natural cycles of light and darkness, to function optimally.

Consequently, anything that disrupts these rhythms, like inadequate sunlight exposure to the body or chronic exposure to unopposed blue light from artificial lights, has a far-reaching impact on your body’s ability to function.

Some experts even believe that mal-illumination to light is what mal-nutrition is to food.

The best way to get exposure to healthy full-spectrum light aka Sunlight is to do it the way nature intended, by going outside, exposing your bare skin and bare eyes to the Sun daily.

Full-spectrum light such as Sunlight is also a significant factor in blindness and optimal health.

The widespread use of energy efficient light-emitting diodes (LEDs) may be setting the stage for an avalanche of sight problems in coming decades. The reason for this is because LED lighting has no near-infrared light, emitting primarily blue light, and this has biological consequences that impair vision over time.

The heat generated by incandescent light bulbs is actually highly beneficial to your health, and hence worth the extra energy cost.

In our eyes, the near-infrared light range primes the cells in your retina for repair and regeneration from the damage blue light causes in the retina, and LEDs, which have virtually no infrared and an excess of blue light, generates reactive oxygen species (ROS) instead.

We need some blue light, especially in the morning for melatonin production, but we need it to be balanced with the healing and repairing red and near-infrared frequencies, like it is in natural sunlight.

This explains why LEDs are so harmful for our eyes and overall health.

The same applies to electronic screens such as TVs, computers, tablets and smartphones. They all emit primarily blue light, and the excess ROS generation may have a great deal to do with the deterioration of vision. The blue light is also deleterious for your circadian rhythm. Electronic screens should be avoided at least a couple of hours before bedtime to avoid suppressing melatonin production.

The research shows that infrared light exposure may even reverse AMD. Even more remarkable, infrared light over the thyroid area has been shown to reverse hypothyroidism.

It seems the more we learn about light, the more importantant it appears to be for biological functioning and optimal health. It’s important to realize that light is actually a significant part of the equation for biological energy production, specifically at the mitochondrial ATP level.

Light affects our overall health, not just oour eyes.

Importantly, full-spectrum light, meaning light that includes the near-infrared spectrum (750 to 1400 nm) generates structured water in our cells, which plays an important role in biological functioning, including our cardiovascular function.

In Summary

To protect our eyesight and overall health, be sure to get bright Sun exposure especially in the early part of the day and, when indoors, use clear incandescent light bulbs in areas where you spend most of the time.

Candles can also be used, especially at night, and are even better and healthier than incandescents.

Experts say that it is imperative to use blue-blocking glasses after sunset, unless the only light exposure you have is candles. Once you have your glasses on, it does not matter what kind of light bulbs you use.

When it comes to computer screens, it is important to reduce the correlated color temperature down to 2,700 K, even during the day, not just at night. It is  better to set it below 2000K or even 1000K.

Many use f.lux to do this, and there is an alternative called Iris. It is free, but you will want to pay the $2.00 and reward him with the donation. You can purchase the $2 Iris mini software here.

Iris is better because it has 3 levels of blue blocking below f.lux: dim incandescent, candle and ember.

It is important not to expose the retina to the damaging effects of blue light after sunset.

    God bless you for telling the truth about sunlight. Recent research has shown that sun deprivation is contributing to the deaths of 336,000 people per year.

    Here are a few more scientifically-documented healthful effects of sun exposure:

    •A 20-year Swedish study shows that sun avoidance is as bad for the health as cigarette smoking.
    •A Spanish study shows that women who seek the sun have one-eleventh the hip fracture risk as those who avoid sun.
    •Men who work outdoors have half the risk of melanoma as those who work indoors.
    •Women who totally avoid the sun have 10-times the risk of breast cancer as those who embrace the sun.
    •Women who sunbathe regularly have half the risk of death during a 20-year period compared to those who stay indoors.
    •Sun exposure increases nitric oxide production, which leads to a decrease in heart attack risk.
    •Vitamin D, the sunshine vitamin, is essential to human survival, and sun exposure is the only natural way to obtain it. Sunbathing can produce 20,000 units of vitamin D in 20 minutes of whole-body exposure.
    •Sun exposure dramatically improves mood through the production of serotonin and endorphin.
    •Beyond vitamin D, sun exposure also stimulates the production of endorphin, nitric oxide and BDNF, all of which are vital to human health.
    •Regular sun exposure also reduces high blood pressure, heart disease, psoriasis and multiple sclerosis (MS).
    •As sunscreen use has increased dramatically, melanoma has INCREASED exponentially.
