Danni da luce blu, come proteggersi. Prevenzione sanitaria

A study by researchers at Oregon State University was published in the journal Frontiers in Aging with research on the damage that excessive exposure to blue light from computers, smartphones, and TVs can cause, not only eye problems but also accelerated aging.

In fact, they observed that with exposure to blue light, the level of glutamate, an important neurotransmitter, suddenly drops, and the levels of succinate, essential for the growth of every cell, increase.

Blue light is a component of solar radiation and is not harmful in itself, but the abnormal exposure from our devices could create problems.

Considering that about 60% of the population would spend on average six hours a day in front of a monitor...

Such prolonged exposure would lead to oxidative stress, inflammation (increase in free radicals), dehydration, alterations of keratinocytes and therefore, in the long term, wrinkles, skin sagging, and hyperpigmentation.

How to protect yourself?

Antioxidants are a great ally not only against blue light and can be taken through diet, supplements, herbal teas.

Replace standard LED bulbs with versions that emit less blue light.

Mineral sunscreens with iron oxides.

Blink frequently a very simple action that allows you to moisten your eyes, preventing dryness and redness.

When possible use screen filters, slightly lower the brightness of your devices.

If in the evening you notice swelling and/or redness in your eyes, contact your ophthalmologist who may recommend the most suitable glasses, with blue light filter or anti-reflective, etc.
