Artificial light is all around us – from our phones and laptops to the streetlights outside our windows.
While it may be convenient and necessary for modern life, recent research has suggested that exposure to too much artificial light may be contributing to weight gain.
What is Artificial Light?
Artificial light refers to any type of light that is produced by human-made sources. These can include incandescent light bulbs, fluorescent lights, LED lights, and even the blue light emitted by electronic devices.
Why Does Artificial Light Affect Weight?
Studies have shown that exposure to artificial light can disrupt our body’s natural circadian rhythm. This can lead to a range of health problems, including weight gain.
There are several ways in which exposure to artificial light can contribute to weight gain.
Artificial Light and Sleep
One of the main ways that exposure to artificial light can lead to weight gain is by disrupting our sleep patterns.
Exposure to blue light – the type of light emitted by electronic devices – has been shown to suppress melatonin production, making it harder for us to fall asleep at night. This can lead to fatigue, irritability, and overeating.
Artificial Light and Appetite
Studies have shown that exposure to bright light, particularly in the evening, can increase appetite and disrupt our body’s natural food intake signals.
This can lead to overeating and a higher calorie intake, both of which can contribute to weight gain.
The Connection between Artificial Light and Hormones
Artificial light can also disrupt hormone levels in the body, which can contribute to weight gain. Exposure to blue light has been shown to increase levels of the stress hormone cortisol, which can lead to increased fat storage and weight gain.
Additionally, exposure to artificial light has been linked to lower levels of the hormone leptin, which is responsible for regulating appetite and metabolism.
How to Reduce Your Exposure to Artificial Light
Reducing your exposure to artificial light can be a challenge in today’s world, but there are steps you can take to minimize your exposure and promote better sleep, appetite regulation, and overall health.
Some tips for reducing your exposure to artificial light include:.
- Using dimmer light bulbs in your home
- Limiting screen time before bed
- Using blue light blocking glasses or apps on electronic devices
- Keeping your bedroom dark and cool
Conclusion
While artificial light may be a necessary part of modern life, it can also have negative effects on our health, including contributing to weight gain.
By taking small steps to reduce our exposure to artificial light, we can promote better sleep, appetite regulation, and overall health.
