What is blue light and where does it come from?
Blue light is a type of light that has a short wavelength and high energy, which can be found in sunlight as well as electronic devices such as smartphones, tablets, and computers.
How does blue light affect our sleep?
Exposure to blue light, especially in the evening and night, can interfere with our body’s production of melatonin, a hormone that regulates sleep. This can lead to difficulty falling asleep and disrupted sleep patterns.
What are the health effects of prolonged exposure to blue light?
Long-term exposure to blue light has been linked to eye strain, headaches, and digital eye fatigue. It may also contribute to an increased risk of macular degeneration, a serious eye condition that can lead to vision loss.
How can we protect ourselves from the harmful effects of blue light?
To reduce exposure to blue light, you can use blue light blocking glasses, adjust the settings on your electronic devices to reduce blue light emissions, and limit screen time before bedtime. You can also try to spend more time outdoors in natural sunlight to balance out your exposure to artificial blue light.
