Exposure to Blue light and how it's effect on your wellbeing

Blue light exposure effects us more unkonwingly than sunlight. We take precausions when we are outside with sunscreen but what about when we are inside?

We have been all under the impression we only needed to protect our skin from the sun.

Well, this has changed.

We’ve come to understand the environment has harsh pollutants which are accelerating the signs of aging.

You have it worse if you live in the big city centers, car fumes, factories and cigarette smoke.

Here, living in the country, we are possibly more fortunate in those regards, but guaranteed we spend a lot of time gardening or outside farming.

But, there’s yet another factor from our everyday lives from which harmful particles are also emitted: our screens.

Facebook time, computer time, TV’s, phones and other electronic devices.

They all emit wavelengths of high energy visible light (HEV light), known as blue light.

HEV light is blue/violet band of visible sunlight spectrum and unlike sunlight, HEV light can be seen.

So, the sun emits HEV light but being in front of our screens for long periods exposes us to more HEV light. The average adult spends up to 9.5 hours in front of a screen.  The pandemic has increased that time.

What isn’t certain is if blue light affects us because we spend more time exposed to it or because we spend closer time near our screens.

Blue Light and Sleep

Another issue of blue light is that blue light at night time throws our circadian rhythm off leading to disrupted sleep. Good sleep is necessary to skin health and wellbeing.

Blue light, isn’t associated with sunburn or skin cancer as UV light is. HEV accelerates the aging process. It increases the likelihood of dark spots (hyperpigmentation) and age spots in addition to wrinkles and fine lines.

HEV encourages free radicals to develop, these are unstable molecules that can harm healthy cells. Simply this damages the fibres that help keep skin looking firm and smooth.

Blue light operates on the basal layers, it penetrates deeper into the dermis where it reaches collagen and elastin.

The effects from HEV light show up slower than UV light, where we see sunburn and the result quickly.

“So, it’s unclear at what point blue light begins to cause damage,” explains Dr. Tailor. It’s believed it happens overtime.

What we need to do:

Firstly, blue light is unavoidable. However, there are some things you can do to reduce your exposure.

Sunscreen.

Not all sunscreen is equal. Most sunscreens protect against UVA and UVB not, HEV light. So, find a sunscreen that specifically targets this and use it when you’re indoors and reapply regularly.

Antioxidants.

These natural compounds are brilliant in helping fight and protect against free radicals. Get them into your skincare routine, which will assist in undoing previous damage.

Hyaluronic Acid.

So, tuck this one into your arsenal. It helps hydrate the skin and reduce the fine lines and wrinkles.

Exfoliate.

You don’t always need to use scrubs to exfoliate. Use a face mit to gently buff away dead skin cells. This will help renew the skin cells underneath to regenerate quickly making your skin look healthier and less dry.
