L is for Light

Updated: Apr 7

When considering light, you might not immediately connect it to your mental and physical well-being, perhaps dismissing it as pseudoscience. However, the impact of light on our health is significant. Light plays a crucial role in regulating our circadian rhythm, also known as our sleep-wake cycle. The abundance of artificial blue light today is linked not only to neurodegenerative diseases but also to mood disorders like Seasonal Affective Disorder (SAD). During the winter months, people who feel low mood and energy often have a deficiency of sunlight.

The sun's full spectrum interacts with our skin and eyes, stimulating serotonin production, a neurotransmitter that regulates mood. In the absence of blue light at night, melatonin is produced, promoting sleep. So, if you're lacking sunlight due to prolonged screen exposure and artificial lighting, you disrupt the hormone balance. Therefore, it's no wonder you can't sleep and feel low in energy.

Do you recall when your parents used to advise you to step away from your screen and go outside? They were actually onto something. Even on cloudy days, the natural light outdoors provides more energy than indoor sources. So, the next time, remember this: if people can take a smoke break, why not consider taking a “light” break for your well-being? Do you want to learn more about light?
