Blue Lights (from digital products)
There are many sources of blue light in our lives; the main source being sunlight; then of course comes all our digital products: computers, iPads, smart phones; fluorescent lights, flat screen TVs...
Believe it or not we need blue light for our health such as helping regulate our circadian rhythms (wake - sleep cycle) and increasing our memory and alertness. However, too much exposure, especially in the dark, can reverse all these benefits. A recent article in ‘The Times’ newspaper stated that this blue light from our digital products can go through the top layers of the skin, destroying collagen, damaging the skin, increasing hyper pigmentation, causing skin ageing, inflammation and oxidative stress. ‘A week in front of the computer can have the same impact on our skin as 25 minutes in the midday sun without sun creams’. It also reduces our melatonin levels, the hormone responsible for our sleep patterns, and increases our stress hormones.
The negative effects do not stop on the skin. This blue light can damage our eyes, causing eye strain, damaging retinal cells even causing age related macular degeneration!
Thankfully there are some simple ways to protect our well being from the blue light:
- Reducing our screen time
- Turning all digital products off at night
- increasing our antioxidants in our diet and skin products
- Watching TV with yellow tinted glasses
- Getting blue light protecting shields for our digital products
Me?? I am very worried about my eyes so I try all of the above!
