It’s no secret that blue light is beneficial to cognitive function. Recent studies have shown that exposure to blue light can improve task performance, reaction time, and vigilance. But what about safety? Are there any risks associated with it? In this blog post, we’ll explore the safety of blue light and discuss how it can be used as a safe nootropic. Stay tuned!
Is blue light safe to use for everyone?
It is safe for use by everyone, with the exception of those who suffer from specific eye conditions. It is a type of visible light that comes from the sun and electronic devices such as smartphones, laptops, and televisions. It is also present in fluorescent and LED lighting.
It plays an important role in our daily lives. It helps us stay alert and focused, and it regulates our natural sleep-wake cycle known as circadian rhythm. However, when we are exposed to too much blue light, it can have negative effects on our health. Too much blue light can cause eyestrain, headaches, fatigue, and problems with sleeping.
What Is Blue Light?
It is light that has a short wavelength and is therefore high in energy. It is one of the colors in the visible spectrum.
It has many uses, including helping us see things in the dark, regulating our circadian rhythm, and treating seasonal affective disorder (SAD). Too much exposure to it can be harmful, however, and can cause eye strain, headaches, and sleep problems. To protect ourselves from the negative effects of blue light, we can use glasses or filters that block it or reduce its intensity.
What Are the Benefits of Blue Light?
The human body has evolved to utilize blue light (480nm) as a signal that it is daytime. It is a key regulator of our circadian rhythm and wakefulness. Blue light, in addition to suppressing melatonin levels, increases our metabolism and alertness. It appears to have significant cognitive effects when consumed. Bright blue light has been found to improve attention, working memory, verbal memory, and mood in randomized controlled trials. This light in combination with caffeine improved alertness and mood more than caffeine alone. Surprisingly, blue light in the day actually improves sleep quality.
There are many benefits, including:
1. Increases wakefulness and productivity.
2. Enhances cognitive function and memory formation.
3. Improves mood and decreases symptoms of depression.
4. Boosts alertness and vigilance.
5. Regulates the body’s natural circadian rhythm (sleep-wake cycle).
It is known as a “neurotrophic” light because it helps to protect and stimulate nerve cells. Neurotrophic factors are proteins or peptides that promote the growth, survival, and differentiation of neurons. The neurotrophic effects of it occur through the activation of adenosine triphosphate-sensitive potassium (ATP-K) channels. When these channels are activated, they cause an influx of potassium ions into the nerve cell, which results in the production of nitric oxide (NO). Nitric oxide is a potent neuroprotective agent that helps to protect nerve cells from damage or death.
Conclusion
It has been shown that our brain activity, cognition, attention and sleep quality are improved by blue light. It is a nootropic supplement for your mind!
