How Artificial Light Affects Your Circadian Rhythm – And What You Can Do About It
In today’s world, artificial light is everywhere – from our homes to our devices, and even in the glow of our cities. But new research by Dr. Seizer, highlighted on NPR, reveals that exposure to bright artificial light, especially at night, disrupts our natural sleep-wake cycles, or circadian rhythms, and may even impact long-term health. Let’s dive into what circadian rhythms are, why they’re so important, and how artificial light could be affecting your body’s natural balance.
What Are Circadian Rhythms?
Circadian rhythms are like your body’s internal clock, guiding essential processes such as sleep, metabolism, and even mood. These rhythms follow a 24-hour cycle and are deeply influenced by natural light and darkness. When the sun rises, our body gets a cue to wake up and stay alert; as night falls, darkness signals the release of melatonin, a hormone that prepares us for sleep. This natural cycle is essential for optimal health.
The Impact of Artificial Light at Night
Dr. Seizer’s study brings to light the hidden health risks of artificial nighttime illumination. Artificial Light at Night (ALAN) has been found to interfere with melatonin production, which can disrupt sleep quality and throw off the body's natural rhythm. According to the study, this disruption doesn’t just lead to groggy mornings but may also have deeper health implications.
Here’s what happens when circadian rhythms are out of sync due to artificial light:
- Increased Cardiovascular Risks: ALAN exposure has been linked to a higher risk of hypertension and cardiovascular problems. The body's normal day-night cardiovascular rhythm can be suppressed, potentially leading to long-term issues.
- Metabolic Disruptions: Circadian misalignment can slow metabolism and may contribute to weight gain and an increased risk of type 2 diabetes. When our sleep and meal cycles are off, so is our metabolism.
- Mental Health Concerns: Sleep disruptions due to ALAN are also associated with mental health challenges, including heightened risks for depression and anxiety.
Tips for Reducing the Impact of Artificial Light
While our exposure to artificial light may seem unavoidable, small adjustments can help align your natural rhythms. Here’s how to reduce the effects of nighttime light and support better sleep:
- Dim Your Lights in the Evening: Opt for warm-colored, dim lights in the evening to ease the transition to sleep. Avoid bright overhead lights and try not to use screens at least an hour before bed.
- Keep a Regular Sleep Schedule: Going to bed and waking up at the same time every day helps your body maintain a strong circadian rhythm, even when life gets busy.
- Get Plenty of Natural Light During the Day: Exposure to natural sunlight during the day reinforces your body’s internal clock. Spending even a few minutes outdoors each day can strengthen your circadian alignment.
