Modern medicine has continually advanced through groundbreaking research that overturns old notions. One such study focuses on the relationship between the skin and the brain. Research suggests that the skin can affect brain function, leading to the notion of skin being termed as the “third brain.”
Relationship Between Skin and Brain
The skin is the largest organ in our body, weighing about 5kg and covering an area of approximately 20,000㎠. Recent studies have shown that the skin is not just a protective barrier but also an important organ that communicates with the brain. Research published in the 2000s indicates that patients with chronic dermatitis scored lower on language memory and attention tests compared to healthy individuals, suggesting that skin condition can influence cognitive functions.
Recent studies have found that the cognitive functions of the elderly improve when they consistently use moisturizing lotions. The diligent application of moisturizing cream has shown to delay cognitive impairment in the elderly. This indicates that skin moisturization can reduce inflammation markers related to aging and enhance cognitive functions.
UV Exposure and Cognitive Decline
There is also research indicating that excessive UV exposure can cause brain cell damage and cognitive decline. A research team at Seoul National University Hospital proved that UV rays negatively affect brain function through the skin. Experiments showed that mice exposed to UV rays exhibited decreased memory and reduced synaptic activity. This research demonstrates that UV rays impact not only the skin but also the brain.
Importance of Skin Care
The skin, being the largest organ, is not just for aesthetics. It is directly connected to the brain, implying that skin health can lead to brain health. Therefore, taking good care of the skin is key to staying young and sharp. As we age, it is essential to combat skin dryness and consistently use sunscreen and moisturizers.
Conclusion
The reason for calling the skin the “third brain” is now clear. Recognizing that skin health is directly linked to brain health and practicing this in daily life is crucial. Apply moisturizer daily and use sunscreen to protect your skin. This will have benefits beyond just looking young. Protecting the skin also protects the brain. Proper skin care can help you live young and smart even as you age.
