Sleep is essential for our health and well-being, yet modern habits and technology often disrupt the natural rhythms that regulate it. A key player in our sleep-wake cycle is the circadian rhythm.
The Circadian Rhythm and Sleep Cycle
The circadian rhythm is a natural, internal process that regulates the sleep-wake cycle, repeating roughly every 24 hours. This rhythm is influenced by environmental factors, especially light exposure. Natural daylight signals our brain to stay alert and awake, while the absence of light triggers the production of melatonin, a hormone that promotes sleep.
In today’s world, we all use artificial lights in our homes at night, and many of us even fall asleep with the TV on or a phone in hand. These devices emit blue light, which makes things even worse by disrupting our natural sleep patterns and making it harder to fall asleep.
How Blue Light Affects Sleep
Blue light, emitted by smartphones, tablets, computers, and LED lights, has a short wavelength and high energy. While blue light during the day can boost alertness, excessive exposure at night suppresses melatonin production, delaying the onset of sleep. Over time, this disruption can contribute to insomnia, fatigue, and other health issues.
How Blue Light Blocking Lenses Can Help
Blue light blocking lenses filter out the blue light spectrum, reducing its impact on the eyes and brain. By wearing these lenses, especially in the evening, you can:
- Reduce digital eye strain and fatigue.
- Support melatonin production by minimizing blue light exposure.
- Improve the quality and duration of your sleep.
These lenses are designed to everyone. You don't need to have a prescription to use them.
Additional Habits to Improve Sleep
-
Limit Screen Time Before Bed
Avoid using digital devices at least two hours before bedtime. Instead, opt for relaxing activities like reading a book (not work-related, just a novel or something relaxing), meditating, or listening to soothing music. -
Create a Sleep-Friendly Environment
Ensure your bedroom is dark, quiet, and cool. Keep in mind the darkest the better to create a restful atmosphere. -
Follow a Consistent Sleep Schedule
Go to bed and wake up at the same time every day, even on weekends. Consistency reinforces your circadian rhythm. -
Get Morning Sunlight
Expose yourself to natural light in the morning to regulate your sleep-wake cycle and boost daytime alertness. -
Avoid Caffeine and Heavy Meals
Limit caffeine intake in the afternoon, your last coffee might be taken at 2 pm and avoid large meals close to bedtime. Both can interfere with your ability to fall asleep. -
Practice Relaxation Techniques
Incorporate calming activities like yoga, deep breathing, or just a warm bath to ease stress and prepare your body for sleep.
