Your nervous system runs on communication. Nerves send signals from the brain and spinal cord out to the rest of the body, and back again. Myelin is the protective, fatty coating wrapped around many nerve fibers. Think of it as insulation around wiring: it helps signals travel faster, more clearly, and with less electrical leakage. ¹

Myelin is also part of a bigger support system. In the central nervous system (the brain and spinal cord), specialized cells called oligodendrocytes help build and maintain myelin. These cells do not just wrap nerves; they also support neurons structurally and metabolically, helping the nervous system meet energy demands over time.

At Natural Eye Care, we want to keep our readers informed about new developments in health and wellness. Sometimes that means looking at breakthrough medical research, such as promising new cancer treatment technology or new findings about inflammation and Alzheimer’s disease. It also means helping you better understand how inflammation may affect eye health and sharing natural ways to support overall wellness. In this article, we bring these topics together to highlight how ongoing research and whole-body health can both contribute to long-term well-being.

Reading at night is recommended for health and improved sleep, compared with staring at electronic screens. Studies show that nighttime reading can improve sleep quality, lower stress, and reduce exposure to blue light, which can disrupt melatonin.¹ Using phones, laptops, tablets, and televisions close to bedtime can make it tougher to drift off. The blue-leaning light they emit can interfere with your body’s natural “time to sleep” signals.²

A large body of scientific research backs up the claim that astaxanthin is great for your body. As a potent antioxidant, astaxanthin scavenges free radicals that cause cellular damage. This benefits many parts of the body, including your skin, eyes, and brain. What is astaxanthin? Where does it come from? And what does the latest research say about its benefits?

Astaxanthin is a Pigment that Makes Seafood Pink

Astaxanthin is a marine xanthophyll carotenoid primarily produced by microalgae like Haematococcus pluvialis. Dietary astaxanthin can be obtained through seafood, including salmon, trout, shrimp, and krill.

The kidneys play a crucial role in supporting brain health and maintaining optimal vision. In this article, we will examine the flow of vital energy in Traditional Chinese Medicine and look at the latest findings on Parkinson’s Disease. Find out how the intricate relationships between the kidneys, brain, and eyes can help you stay healthier as you age.

Traditional Chinese Medicine Meridians

According to Traditional Chinese Medicine, meridians run throughout the body, with many going to the eyes. Therefore, healthy meridian flow is essential for helping maintain and support healthy vision and overall health.

Artificial sweeteners have long been marketed as a “healthier” alternative to sugar, especially for those managing diabetes, obesity, or simply aiming to cut calories. But as we explored in a previous article, mounting research suggests these sugar substitutes may come with hidden health risks that cannot be ignored.

Now, new evidence is shining a spotlight on erythritol—a sugar alcohol commonly found in low-calorie snacks, drinks, and specialty foods. While erythritol is often promoted as a safe, natural option, recent studies suggest it may have unexpected and serious effects on our health, particularly when it comes to brain and cardiovascular function. In this article, we’ll unpack the latest research, explore how artificial sweeteners could affect not just your body but also your vision, and share safe, natural alternatives for those seeking a genuinely healthy way to satisfy their sweet tooth.

Did you know your brain is capable of growing new cells and forging fresh connections, even as you age? The science of neurogenesis is reshaping our understanding of brain and eye health. Neuroplasticity isn’t just for kids! About 30 years ago, scientists began to acknowledge the brain’s amazing ability to adapt in all stages of life. In this article, we will discuss the science of neuroplasticity and how it impacts both the brain and the eyes. Also, we will talk about how neurogenesis regrows brain and eye tissue, and how it could improve eye conditions such as glaucoma. And, we will recommend nutrients that can help your brain build new connections and neurons.

Retinitis Pigmentosa is a progressive eye disease that has long been associated with gradual vision loss and limited treatment options. Affecting about one in every 4,000 people, Retinitis Pigmentosa (RP) is marked by the degeneration of the retina’s photoreceptor cells—first the rods, which are responsible for night vision, and then the cones, which enable us to see in daylight and color. While the genetic complexity and slow progression of RP have posed challenges for patients and researchers alike, recent discoveries are offering new hope. Exciting new research reveals that the retina may have an unexpected ability to adapt: certain retinal cells can rewire themselves in response to degeneration, potentially helping to preserve vision even as the disease advances.

A new study has found a link between vascular diseases, specifically high blood pressure, diabetes, and increased risk for dementia. Vascular risk factors were higher in both female and Black participants, as well as non-carriers of the APOE ε4 gene, which is linked with an increased risk of Alzheimer’s.¹

The statistical results of this cohort study suggest that between 22% and 44% of incident dementia cases by 80 years old were attributed to midlife and late-life vascular risk factors.
