Our face is daily exposed to light waves which can damage and age the skin. But it’s not just the sun causing problems – now some scientists are claiming light from laptops and smartphones can be dangerous too. Electronic devices emit high energy visible (HEV) blue light, which some studies have shown to be as harmful as UVA and UVB rays, penetrating deeply into the skin.
One study has suggested exposure to blue light could affect the skin’s ability to heal – a key factor in speeding up the ageing process, and they’ve created a product to help combat it. Holding a device like a smartphone on a sunny day could increase the skin’s exposure to UV light by up to 75%.
While sunscreen may help protect against UV rays, it won’t protect the skin from blue light. HEV (high-energy visible) light, which is emitted from our phone and computer screens, is as damaging if not more so than UV light from the sun, penetrating more deeply than UV light and has a negative impact on the DNA within the cells as well as causing oxidative stress and inflammation. This all accelerates skin ageing.”
Is it really bad?
Blue light might interfere with the body’s circadian rhythm – which regulates sleep – and it’s when we sleep that our bodies take the opportunity to repair cellular damage.
“Anything which interferes with sleep affects the body’s ability to heal,” he said. “In skin, this means it affects its ability to repair itself which leads to accelerated ageing.”
What to do?
If you’re worried about your levels of blue light exposure you can try a specialist cream designed to block HEV light. Also use an antioxidant serum for protection, a serum at night to stimulate collagen production and stabilize the melanocytes which cause pigmentation. Wearing a good SPF sunscreen will also help limit the effects from reflected UVA and UVB rays.
But experts agree the best prevention is to avoid using your phone for long periods outside.
There are many factors in your daily habits that are accelerating biological age. The good news is that there are ways to reduce and prevent premature aging.
Biological age measures how your body is functioning relative to your actual calendar age. The actual chronological age of a 50 year old with an active and healthy lifestyle can have a biological age of a 40 year old. Taking control of your life reducing bad habits will have beneficial results in the long run.
Extended sun Exposure
The number one cause for premature aging is not applying sunblock. Sunlight delivers a daily dose of beneficial Vitamin D but extreme exposure to sunlight can harm your skin if you don’t wear sunblock. Limit the exposure sun rays to can be harmful after 1hr of exposure and lead to wrinkles and cancer in the long run. Wear sunscreen with at least 15 SPF plus and reapply every hour depending on the activities. The sun in mid afternoon is the strongest and is best to avoid direct exposure. Wear hats, sunglasses and protective UPF clothing, when you have to be outdoors for a while.
Lack of Sleep
Not sleeping well can cause circles under your eyes to appear or become more prominent. The lack of sleep cause the blood vessels under the thin skin of the eyes to dilate, creating a dark tint.Sleeping is important for overall mental and physical health. Lack of sleep can take toll on your daytime energy, productivity, and even your weight. Balancing your daytime routine and bedtime habits increase the quality of deep sleep, increases awareness, balance emotions, and energized.
At night, these cells work to repair damage caused by sunlight, pollution and more. when the skin is unable to complete the repair process it will lead to premature aging.
Smoking kills cells that produce collagen reducing the suppleness and elasticity of your skin. Also deteriorates your lungs in the long run.
