In this digital age, the harmful effects of excessive exposure to artificial light during at night are often overlooked health concern. Sure, blue light has a good effect as it sends a signal to our body to stay awake, boost our energy and can elevate our mood during the day. However, many people are unaware that the blue light exposure after the sun goes down have multiple impacts on human health most especially, the eyes. Also, too much exposure to blue light has a negative impact on circadian rhythm – the human body’s natural sleep and wake cycles, resulting in a lack of sleep that can cause hypertension.

What is Blue Light?
Blue light is a color in the visible light spectrum which is believed to have a very short wavelength, hence, produces a higher amount of energy. Scientific studies suggest that blue light exposure over time can cause long-term damage to our eyes such as blindness. As mentioned, exposure to blue light during the day has many health benefits as well. It keeps us active during the day and sends a signal to our body when it is time to sleep during the night.
Ideally, we should not be exposed to blue light after sunset. This is the time we should be winding down and prepare for a good night sleep. But this is not the case in today’s world full of digitalization wherein most people are still awake at night staring at a digital screen of television, smartphones and computers. Not to mention the other artificial lighting like LED and fluorescent light.
