Too much of this makes you look old

We’ve always lived with blue light from the sun. Now we’re getting it from our electronic screens too. So we’re exposed to a lot more blue light than we used be.

And it’s crazy how much time people are spending on their phones these days! Depending on which poll you read, people are averaging anywhere from 3.25 hours to 5.7 hours each day on their smartphones…every day.

Do the math and that adds up to between 53 and 86 days a year on their phones.

You already know it’s bad for your eyes. You can tell that by the eye fatigue and strain you experience.

But did you know it’s also secretly aging you?

Just think about it. When you’re on your smartphone, tablet or computer the blue light is shining directly on your face and neck. It’s up close and personal. Even the flashes from taking selfies can accelerate skin aging.

This blue light can drill all the way down to your dermis. That’s where your collagen and elastin are. They are what make up your skin. They keep it firm and elastic. But when blue light penetrates the dermis, it starts breaking them down.

Your skin loses its elasticity and firmness. It starts sagging. Wrinkles begin to show. Age spots and hyperpigmentation make their presence known.

What’s interesting is this…

You can Repair Blue Light Skin Damage

If you sprayed some copper directly onto your skin, or increased your oral intake of copper, you would help repair your skin.

That’s because copper aids in the cross-linking of elastin and collagen to repair connective tissues and make new skin. It is also vital to the melanin that maintains the pigmentation of your skin. (Copper also plays a role in maintaining your natural hair color.)

There are several brands of copper facial sprays available on the internet. I haven’t tried one yet, but If you decide to give one of them a try, look for one that doesn’t contain a lot of extra ingredients. The more names you can pronounce and the shorter the ingredient list, the better off you are.

Eating the right kinds of foods can also help repair and ward off damage from blue light.

In general, a diet high in vegetables, fruits, olive oil, nuts, legumes and fish is going to offer protection against skin aging.

A diet high in meat, dairy, sugars, processed foods and fried foods is going to have the opposite effect.

It’s as simple as that.

What about Your Eyes?

I protect my eyes at work with a blue blocker. These are regular glasses that have the lenses that block blue light. I get awful headaches and blurred vision without them.

And here’s an interesting tidbit.

These types of lenses started with the NASA space program. As you can imagine, the astronauts needed some pretty strong protection for their eyes while up in space, where ultraviolet rays are a lot stronger than they are down here.

You also have a few other protective options besides light blocking glasses.

A lot of smartphones have a blue light filter setting on them these days. Even if your phone doesn’t have one, there are plenty of apps for them that you can download.

For your larger devices, a blue light blocking screen protector might be a good option. (You can probably find these for more popular smartphones too, like Samsung Galaxy and iPhone.)

Regardless of which option you choose, it’s always a good idea to protect your skin and eyes from blue light as much as possible – whether at your computer or outdoors in the sun.

I recently made a visit to my dermatologist. Sitting in the exam room, she remarked, “Oh, you’ve got some color there.”

“Yeah,” I replied with a grin. “I’m working on my tan.”

What came next was a lecture on the dangers of spending too much time in the sun. Continue reading

Why the Term “Safe Sunscreen” is a Hoax

By David Blyweiss, M.D., Advanced Natural Wellness

June 5, 2019

There is a formidable document that has been sitting on my desk for a couple of months now. Today, I finally took the time to read it in full.

It’s a much needed FDA proposal for updated sunscreen regulation. And with summer nearly upon us, I think it’s important that you know the facts. (This is one of the few times the FDA – which usually works at cross-purposes – is in agreement with my viewpoint.)

In the past, I have been very vocal about the potential harms of certain sunscreen ingredients. And a lot of patients scoff at my concerns. Continue reading

#1 Anti-Cancer Vitamin

  • Vitamin D: The anti-cancer vitamin
  • 77% of cancer patients have low levels of the sunshine vitamin
  • Here’s how to bring your vitamin D levels up to par

You’ve been told to stay out of the sun… that it will give you skin cancer. But that advice is only partially true. It is intense, intermittent exposure (like that from tanning beds and a full day on the beach once in a while) and the burning that subsequently occurs that increases the risk of skin cancer, specifically melanoma.

As a result of this constant advice to avoid sun exposure, vitamin D deficiency is running rampant here in the U.S. As a matter of fact, it’s estimated that as many as three out of every four people have vitamin D insufficiency.

This means you only have about a 25% chance of having adequate levels of vitamin D. And guess what happens when you your vitamin D levels run low? Continue reading

Are You Using the Wrong Sunscreen?

By David Blyweiss, M.D., Advanced Natural Wellness

  • Don’t let sunburn ruin your summer fun
  • The trouble with most sunscreens
  • Always do this before applying sun blockers

It’s that time of year again… hot, sunny days that beg for an outdoor barbecue, picnic or a day at the pool or beach.

These are all great summer activities. But the fun can disappear pretty quickly if you wake up the next morning with a blistering sunburn.

Red, peeling and raw skin isn’t just painful. It’s also an indication that the DNA in your skin cells has been damaged. When this type of damage occurs, it causes DNA mutations that increase your chances of skin cancer.

This makes it very important to choose the right sunscreen and apply it every hour or two throughout the day.

But is all sunscreen safe? Continue reading

Why Some Sunscreens are Worse for You than the Sun

By David Blyweiss, M.D., Advanced Natural Wellness

  • Exposed! Not all sunscreens are created equal
  • Is your sunscreen robbing you of vitamin D… or giving you cancer?
  • The only kind of sun blocker you should ever buy

You would think that vitamin D deficiency would be unheard of down here in South Florida. After all, this is the sunshine state. And where there is plenty of sunshine, there should be plenty of vitamin D.

Still, vitamin D insufficiency is just as common down here as it is in any other state. I’ll place that blame squarely on the shoulders of our fear of the sun – and over reliance on sunscreen protection. Continue reading

How to Moisturize from the Inside Out

  • Does dry skin have you itching and scratching?
  • How to moisturize from the inside out
  • Winter skin begs for more of the sunshine vitamin

If you live in a cold or dry climate, you know how harsh it can be on your skin. This kind of weather can give you skin that’s dry, itchy, flaking, cracking, bumpy and downright annoying.

The problem begins when you start losing the natural oils your skin cells make to keep water trapped inside your body. These oils are what keep your skin feeling soft and supple.

But during the winter months, indoor heat sucks the moisture right out of your skin. And if you’re like most people, you probably start overcompensating to correct the problem. Continue reading

5 Personal Care Products Lurking in Your Bathroom

•    What’s hiding in your shampoo, deodorant, soap and shaving cream?
•    Watch out for these common estrogen mimics
•    How to keep hormone-busting chemicals out of your personal care products

When it comes to your health, your bathroom is one of the most dangerous rooms in your house. And it’s not the germs from your toilet bowl that I’m talking about.

Rather, it’s all of those personal care products you have in your hiding in your medicine cabinet, filling your shower rack and littering your bathroom counter. Soaps, shampoos, deodorants, lotions, shaving cream… they all present a bigger threat to your health than you would imagine.

Sure, all of that stuff makes you smell great and look good. But have you ever read the labels on some of those products?

If so, I’ll bet you found a lot of words you can’t pronounce, let alone spell. And many of those long, tongue-twisting ingredients come with horrible side effects.

  • Psoriasis cures your doctor won’t think to try

Growing up, it seemed like one kid every year always bore the brunt of teasing – usually for being noticeably different in some way. In third grade, it was the girl with scaly skin. Who always wore turtlenecks and long sleeves, in every kind of weather. And who was still tugging at her sleeves so they would cover her red, scaly wrists and hands. Continue reading
