Humans with dark skin pigmentation have skin naturally rich in melanin, especially eumelanin, and have more melanosomes which provide superior protection against the deleterious effects of ultraviolet radiation. This helps the body to retain its folate reserves and protects against damage to DNA.
Dark or tanned skin often has higher melanin content, which provides better natural protection against UV radiation, reducing the risk of sunburn and skin cancer. Additionally, darker skin may have advantages in certain environments, as it can help retain moisture and reduce signs of aging.
The preference for more golden or 'yellow-toned' skin as healthier might be explained by the 'carotenoid pigments' that we get from the fruit and vegetables in our diet. These plant pigments are powerful antioxidants that soak up dangerous compounds produced when the body combats disease.
Black skin typically has more melanin, providing more protection from UV rays but also making it more prone to hyperpigmentation. White skin has less melanin, making it more susceptible to sun damage but less prone to certain types of pigmentation issues. Skincare needs can vary based on these differences.
The primary benefits of dark skin over light are better resistance to aging and much less risk of skin cancer in comparison with lighter-skinned people. These benefits stem from the fact that dark skin has more melanin – a compound which protects skin by acting as a natural sunscreen.
According to a study called “Shades of beauty,” light brown skin tones are often the most physically attractive skin color (Frisby et al., 2006). They used four models for that study. They did not change the skin tone, but they imaged each model to three different skin tones: light, medium, and dark.
Sleeping in a dark room has a number of benefits not only to your sleep quality but your overall health including, but not limited to, promoting a faster metabolism, lessening the chances of developing type II diabetes, and enhancing your mental focus by allowing you to complete your sleep cycles.
Skin barrier function is reportedly stronger in darker skin tones (the stratum corneum is the skin barrier). Asian skin is reported to have similarities with Caucasian skin in terms of water loss and has the weakest barrier function.
The fact that darker skin ages at a much slower rate has actually been demonstrated: signs of skin aging become visible around 10 years later compared to lighter skinned people of Northern European or North American ancestry.
Dark-skinned people living in low sunlight environments have been recorded to be very susceptible to vitamin D deficiency due to reduced vitamin D synthesis. A dark-skinned person requires about six times as much UVB than lightly pigmented persons.
Discolored skin
Color changes to the skin can sometimes indicate underlying illness. "Skin sometimes looks gray, sallower, in people with underlying chronic illness," says Dr. Brod. Yellowish- or orangish-looking skin can be a sign of kidney or liver disease.
Normal skin: The best of all, it is balanced, not too oily or dry, with smooth skin texture. Sensitive skin: Gets easily irritated, and prone to redness, burning, or itching.
In some cultures, lighter skin has been associated with privilege, power, and social status, creating a bias towards individuals with paler complexions. This bias is deeply rooted in historical constructs of colonialism, where lighter-skinned individuals were often viewed as superior or more desirable.
The preference for more golden or 'yellow-toned' skin as healthier might be explained by the 'carotenoid pigments' that we get from the fruit and vegetables in our diet. These plant pigments are powerful antioxidants that soak up dangerous compounds produced when the body combats disease.
Blue-eyed, fair-skinned people show more aging skin changes than people with darker, more heavily pigmented skin. With aging, the outer skin layer (epidermis) thins, even though the number of cell layers remains unchanged. The number of pigment-containing cells (melanocytes) decreases.
Findings indicated that non-Hispanic Blacks and Hispanics have accelerated aging, and non-Hispanic Whites have decelerated aging.
While dark skin is better protected from ultraviolet radiation, it does absorb more of the energy in visible light than light skin. But most of the sun's heat comes in invisible infrared radiation. Dark and light skin are the same color in that range. Dark skin absorbs no more heat than light skin does.
Abstract. Traditionally, Asians have been thought to age more gracefully than Caucasians. The resistance to aging in the Asian patient was credited to the thicker dermis of Asian skin that contains greater collagen and the darker pigment that protects against photoaging.
Whites are usually taken as the standard against which other groups are compared, but they are not necessarily in the best health. Hispanics appear to be healthier than whites on a number of measures, though not all. Asians are generally in better health than any other group (Hummer et al., 2004).
Golden skin tones are medium skin tones. This skin tone is usually seen in people of Asian and Southern European ethnic descent. It can also be referred to as olive skin. This skin tone has a balanced neutral beige hue.
Darkness stimulates the pineal gland located deep in the brain to produce melatonin, which is a serotonin-derived hormone that promotes sleepiness. Light exposure inhibits that process, thus blocking melatonin production and providing another barrier between us and sound sleep.
Firstly, for some people, darkness is a source of comfort. It allows them to relax and feel safe. This is especially true for those who suffer from anxiety or have experienced trauma.
While some research supports sleeping in a cold bedroom, other research supports a slightly warmer sleep environment. The World Health Organization (WHO) recommends a minimum temperature of 64.4 degrees Fahrenheit (18 degrees Celsius), and the European standard recommends 68 degrees Fahrenheit (20 degrees Celsius).
