Skin is our body’s largest organ, but how much do we know about the role it plays in our health?
Changes in the skin can reveal a lot about our health. Our skin does a big job for us. Each inch of our skin is made up of 19 million skin cells, 650 sweat glands, 20 blood vessels, and 1000 nerve endings. It is our first line of defense against the outside world which includes allergens and irritants. Maintaining a healthy skin barrier is important. Our skin is more like an immune organ than a protective organ.
Respect your skin with smart skin care habits that will help you keep it healthy. Knowing these cool facts will help you care for your skin.
Your Skin is hiding a Secret
Even if you are diligent about applying a broad-spectrum sunscreen daily now, there may have been a time when you were not so careful. Those habits might catch up to you. You may not be able to see it in the mirror but UV photos can reveal the sun damage simmering beneath your skin. Use a retinoid at night also with using products with SPF daily, to slow and reverse these effects. Retinoid is skincare products that help treat acne, combat early signs of aging, and help heal sun-damaged skin.
Skin Plays an Important Role in Regulating Our Body Temperature
Not only does our skin play a role in our immune function but it also acts as a personal thermostat through a process known as thermoregulation.
Sweating is a body function that helps regulate our body temperature. Our skin has around two to four million sweat glands. Sweating isn’t the only way of keeping you cool, our skin helps cool us down via vasodilatation also. It occurs when blood vessels just below the surface of our skin dilate, allowing for increased blood flow and heat dissipation.
Dry Skin in the Winter Isn’t Only Uncomfortable – It May Be Harmful Too
When the temperature begins to dip in the winter, harsh wind and indoor heating systems can suck the moisture out of our skin. The skin needs to be a healthier barrier to prevent infection. But the dry skin is a cracked and broken barrier. Many people think dry skin is cosmetic, but it can also increase our risk of infection.
Our Skin Renews Itself Every 28 Days
The epidermis is the thin outer layer of our skin, which contains dead skin cells. It is this epidermis that turns over every 28 days. New skin cells generate at the bottom of the epidermis and it takes them about a month to reach the surface as dead cells naturally sough off. We can also help clear these dead cells away and keep our skin looking bright by exfoliating our skin regularly.
Our Skin Can Respond Negatively to Stress
Stress triggers a high level of cortical and inflammatory molecules called cytokines that spread throughout the body. This leads to a rise in inflammatory markers that trigger matrix metalloproteinase, enzymes that break down collagen molecules in the skin. Collagen is a protein that gives skin its youthful, bouncy elasticity. Major illness or events that have the power to trigger chronic stress could affect our skin.
