" Blue light emitted from digital screens and lights suppresses the melatonin secretion in our body."
In this current digital era, we are spoiled with the affordability of high-tech gadgets such as smart phones, computers, TVs and tablets. Almost everyone uses smart phone, TV and computer everyday. Without a doubt, life is much easier with these products. Be it at or off of work, digital devices have become a huge part of our life. In fact, for many of us, nothing can separate us from our smart phones.
How healthy is our obsession with digital devices? What are the impacts from using these gadgets intensively on our health and wellbeing?
Digital Devices Emit Blue Light
According to Prevent Blindness, digital devices are less likely to cause cataract compared to the sun. Nevertheless, digital devices emit certain amount of blue light. It is significantly weaker than the amount of blue light emitted by the sun. Nevertheless, considering how close our body from these gadgets and how long we expose ourselves to blue light emitted by digital screens everyday; do these devices affect our health and wellbeing?
A recent study showed that children's eyes absorb more blue light than adults's eyes. According to World Health Organization (WHO), retinopathy of prematurity (*) is the main cause of vision impairment among children in high-income countries. Can the long term and intensive exposure to blue light from digital devices be the reason?
(*) Retinopathy is a damage to the retina caused by abnormal blood flow.

Exposure To Blue Light At Night Suppresses The Melatonin Secretion
A research study by Harvard Medical School showed that the exposure to blue light emitted from digital screens and lights at night suppresses the melatonin secretion in our body. Melatonin is the hormone which regulates the body clock. This hormone is very crucial to our health and wellbeing. Melatonin helps us to fall asleep at night. The decreasing amount of Melatonin can negatively impact the normal functioning of our body. However, we all should be aware that the exposure to blue light during the day will not suppress the melatonin secretion in our body. In fact, the exposure to blue light from the sun can be good for our health and wellbeing.
If you often find it difficult to fall asleep at night, avoid watching TV, using mobile phone or computer at least few hours before going to bed. Unless for something urgent, reduce your exposure to digital devices to a minimum at night.
Digital Devices and Eye Strain
Looking at a digital screen for a long period of time may cause eye strain due to fatigue or dry eyes. A study published in the British Journal of Ophthalmology suggested that the proportion of people in high-income countries who suffer from eye impairment is on the rise. Whether or not this has anything to do with the increased exposure to blue light emitted from digital devices is still a question to be answered.
As an anti-ageing scientist, I often work in front of the digital screens on and off for as long as 14 hours a day. It can be very tiring for the eyes. If you work in front of computer all day, rest your eyes frequently to reduce the risk for eye strain. The skin around the eyes is much thinner and more fragile than those on the other parts of your face and body. It is lacking of sebaceous glands, collagen and elastin fibres; hence, it is prone to dryness and environmental damage. To protect the skin around the eyes from premature signs of ageing, apply Anti Dark Circles and Puffiness. This brightening anti-ageing eye serum has been formulated with niacinamide, ferulic acid, caffeine and centella asiatica plant extract to diminish dark circles, puffiness, wrinkles and other signs of ageing.
