How Vitamin D Helps Protect Your Skin And Lower Cancer Risks Naturally

Vitamin D and the role in health, skin cancer prevention

Known as the "sunshine vitamin," Vitamin D is essential to healthy skin, but one aspect of vitamin D's association with skin cancer is somewhat intriguing. Although some level of sun exposure is necessary for your body to make vitamin D naturally, it's informative to understand the balance of these benefits with the increased risk of skin cancer due to excessive UV radiation. 

Here's how vitamin D supports your skin and how it may impact the risk of skin cancer:

<strong>1. Skin Barrier Protection</strong> 

Vitamin D is useful for the creation and proper functioning of outermost skin layer cells called keratinocytes. It acts as a protective shield against excessive loss of water; otherwise, the body would become too dry, and it protects the body from harmful environmental pollutants and pathogens. 

It obviously helps minimize risks of catching infections and eczema or psoriasis. More importantly, this barrier function is crucial to maintain the integrity of the skin, and thus might lower the risk of developing some types of skin cancers by minimizing damage through environmental stressors.

<strong>2. Immune System Modulation</strong>

Vitamin D has a critical role in regulating the immune system, which is an important factor for the prevention of skin cancer. The immune system is always on the lookout for abnormal growth of cells or other potentially cancerous changes. Vitamin D enhances the activity of these immune cells: macrophages, monocytes, and T cells; which are essentially required in the body's defense systems. 

It enables a potential, proper immune response to identify and destroy precancerous cells prior to full-blown skin cancer like basal cell carcinoma or squamous cell carcinoma.

<strong>3. Antimicrobial Activity and Inhibition of Skin Cancers</strong>

Vitamin D has antimicrobial effects, contributing to its protection of the skin from infection. Though infections have not traditionally been associated with skin cancer, chronic inflammation and continuous infection resulting from repeated or neglected infections are facilitating to carcinogenesis. 

Vitamin D can ensure that the skin is more resistant to chronic inflammation and infection, which could thereby reduce its risk for cancer.

<strong>4. Regulation of Sebaceous Gland</strong>

Vitamin D controls the functioning of the sebaceous glands because they produce sebum. This biological oil feeds the skin by keeping the skin hydrated and at the same time protects it from environmental factors. Adequate rate of sebum's production, which vitamin D helps maintain, can thus prevent acne and may later cause damage to the skin. 

Even though the relationship between vitamin D and acne is complex, keeping in view the general maintenance of skin health by proper oil regulation will prevent the skin from becoming more susceptible to cancerous changes that result from chronic irritation or inflammation.

<strong>5. Wound Healing and Skin Cancer Recovery</strong>

Vitamin D is crucial for wound healing, an essential element in recovery after injury to the skin, which can include surgical removals of lesions with skin cancer. Vitamin D promotes the expression of cathelicidin, an antimicrobial peptide, which is essential for tissue repair and regeneration of the cutaneous barrier. 

Vitamin D status supports the recovery from antitumor therapies, such as surgery or radiation, by enabling rapid skin regeneration and reconstitution.

<h2>Ayurvedic Perspective on Vitamin D and Skin Health</h2>

In Ayurveda, the vitamin D level is associated with a state of equilibrium of the doshas of Vata, Pitta, and Kapha in the human system. An Ayurvedic concept toward health suggests prevention of diseases by exposing one's body to both natural sunlight and nutritional food containing this utmost requirement. 

While it is always stated that the primary source of vitamin D is the sun, Ayurveda advises the taking of foods like fatty fish, egg yolks, and fortified dairy products so as to complement this natural balance for healthy skin. Ayurvedic practices, for example, also advocate lifestyle changes to achieve optimal vitamin D levels in relation to doshic requirements of an individual, which not only aids general well-being but could reduce the chances of skin diseases such as cancer of skin.

<h2>Lifestyle Practices for Optimal Vitamin D Levels and Skin Cancer Prevention</h2>

Some of these lifestyle changes to get full benefits from vitamin D while ensuring minimum hazards to the skin or risk of causation of skin cancer include

<strong>- Moderate Sun Exposure:</strong> This is about 10 to 15 minutes of sun exposure a couple of times a week, not exposing your skin to too much UV radiation that could increase your risk of developing skin cancers. The bottom line is, about striking a balance between getting enough sunlight to stimulate vitamin D production without causing skin cells to break down.

<strong>- Vitamin D Rich Diet Intake:</strong> Consume vitamin D-rich food. This includes eating salmon, mackerel, and egg yolks and even the various fortified dairy products. All those listed provide help in maintaining the right amount of vitamin D for healthy skin and proper immune actions.

<strong>- Supplements When Needed: </strong>If you cannot obtain enough vitamin D through your diet or sun exposure, supplements will be necessary. A healthy vitamin D level is important for your overall health and sun defense, especially if you live in an area that does not offer much in the way of direct sun exposure or have diseases that impair the absorption of vitamin D.

<strong>- Balancing Sun Exposure with Skin Cancer Prevention: </strong>Sunlight is an excellent natural source of vitamin D, but high exposure to UV may increase the chances of skin cancer, specifically melanoma, basal cell carcinoma, and squamous cell carcinoma. The balance has to be achieved in obtaining enough sun for the production of vitamin D without having a lot of risk of UV. 

In achieving this goal, one may benefit by sun while simultaneously reducing risk from skin cancer through application of sunscreen, protective clothing, and shaded places during the peak times of sun exposure.

Worried About The New And Dominant COVID Variant XEC? 3 Things You Must Know

worried about the new and dominant covid variant xec? 3 things you must know

Human papillomavirus (<span>HPV</span>) is a virus that affects every sexually active person at some point of their life, even if there are no symptoms. The <span>World Health Organization</span> explains that it can affect the skin, genital area, and throat. While preventative measures do help, they cannot totally protect themselves from transmission. Despite the contagious nature of the virus, these infections go away without treatment. However, there are some likely scenarios where they can cause abnormal cells to develop, which later on become cancer. 

What deters many people from getting themselves checked out is the general stigma surrounding sexually transmitted infections or diseases. So, when at home tests became available, the rates screenings improved a lot! 

A new study suggests that women are much more likely to get screened for HPV (human papillomavirus) if they can do the test themselves at home in private. This is a big deal because almost all cervical cancers are caused by HPV. Researchers found that when women were offered a mail-in test kit, the number of women getting screened more than doubled. 

<h2>Why <span rel="noindex">At-Home Testing is a Game-Changer</span> </h2>

Around 11,500 women are diagnosed with cervical cancer each year in the U.S. Sadly, more than half of these women have either rarely or never been screened for HPV. Traditional screening often involves a pelvic exam at a clinic, which can be uncomfortable or distressing for some women. It also requires them to take time off and travel to the clinic. 

The good news is that the first at-home screening test for cervical cancer recently got approved for use in the U.S. and should be available very soon. This new option could make a huge difference in how many women get screened. 

To see how at-home testing would work in real life, researchers studied nearly 2,500 women aged 30 to 65. They divided the women into three groups: 

<ul><li>One group received a phone call reminding them to go to a clinic for screening.</li><li>Another group was mailed an at-home self-collection test kit.</li><li>The third group received an at-home kit and also got a follow-up call if they didn't return their kit quickly.</li></ul>

The results were clear: women who were offered an at-home test kit were more than twice as likely to get screened. About 41% of those who received a kit participated, compared to only 17% who just got a phone reminder to go to a clinic. When women who received a kit also got follow-up reminders, participation jumped even higher, to 47%. Interestingly, over 80% of the women in the test kit groups who participated chose to mail in their kit for analysis, rather than going to a clinic. 

<h2>Making At-Home Tests Accessible </h2>

The study also found that about 13% of the women who returned a kit tested positive for a high-risk type of HPV. As these self-collection tests become more widely available, it's crucial to ensure they are offered in clinics and health centers, especially for people who face bigger challenges in accessing healthcare. By removing these hurdles, experts hope to increase screening rates and significantly reduce the burden of preventable cervical cancer. 

Researchers now plan to investigate how to best use these HPV self-collection tests in different healthcare settings. While at-home HPV testing offers great promise, the next challenge is to make sure it's adopted safely and effectively into regular medical practice. This includes figuring out how healthcare providers can best follow up with women who have abnormal test results.

Hay Fever Is Worse Than Ever This Year- Avoid These 3 Everyday Triggers

hay fever is worse than ever this year- avoid these 3 everyday triggers

As per the American Society of Cataract and Refractive Surgery, June is the <span>cataract awareness month</span>. This has been designated as a month to spread awareness around cataract and educate the public about it. This is also the leading cause of <span>vision loss</span> worldwide. This month-long observance also highlights the importance of early detection and treatment of cataracts, and emphasizes that prompt intervention can significantly preserve vision. 

<h4>Why Is It Declared As The <span rel="noindex">Cataract Month</span>?</h4>

As per the International Agency for the Prevention of <span>Blindness</span> (IAPB), this has been done to provide patients and professionals with free educational resources on cataract, which is the clouding of eye's lens. According to the Centers for Disease Control and Prevention (CDC), cataract is the leading cause of blindness worldwide and the leading cause of vision loss in the United States. An estimated 20.5 million Americans aged 40 year and older have cataract in one or both eyes. 

It is the clouding of eye's natural lens, which sits just behind the iris. In a healthy eye, this lens focuses light onto the retina, allowing us to see clearly. Over time, due to aging or other factors, this lens may become cloudy, leading to blurred or dimmed vision. 

As per the World Health Organization (WHO), cataracts account for nearly 51% of world blindness and affects over 65 million people. 

<h4>History Of Cataract Awareness Month </h4>

Prevent Blindness declared the month of June as Cataract Awareness Month and it has been joined by other organizations, including the American Academy of Ophthalmology (AAO), and UNC Ophthalmology. This month spotlights an ocular disease. 

The earliest documented case of cataract was reported to be in a museum in Cairo that houses a small statue from the 5th dynasty. The wooden statue is of a priest reader who has a white patch carved into the pupil of the left eye. It is thought to represent a cataract. 

The earliest procedure of cataract removal is couching. Several illustrations too have been found inside Egyptian temples and tombs depict surgical instruments that indicate the use of couching, a procedure that involved dislodging the eye lens to clear the cataract. 

<h4>How Does Cataract Affect Vision?</h4>

<ul><li>Blurred or foggy vision</li><li>Increased sensitivity to light or glare</li><li>Difficulty seeing at night</li><li>Colors appear faded or yellow</li><li>Frequent changes in glasses prescription</li><li>Seeing halos around lights</li></ul>

Cataract are caused by various factors, some of which include diabetes, prolonged exposure to UV rays, smoking and alcohol consumption, long-term use of corticosteroids, and eye injuries. 

The best way to prevent them is to wear UV-protective sunglasses, manage systemic conditions like diabetes and also go for regular eye exams, especially after the age of 40. It is also important to focus on your diet and other lifestyle habits, and consume more green leafy vegetables, and fruits.

Nature is filled with amazing flora and fauna, all with different sets of abilities and unique features. While considered impossible for humans, there are many animals that can <span>regenerate</span> part of their bodies. Sea creatures like starfish and octopuses can regenerate their limbs in case they get hurt or have to decapitate themselves to escape from a difficult situation. Living in the wild, these creatures evolved to adapt to the harsh nature of their surroundings. 

This is not the case for humans. Many people have to live without their limbs or organs, whether it is due to being born that way or being hurt/experiencing an accident. However, taking inspiration from one such animal, researchers are looking into human limb regeneration. 

Axolotls, with their unique smiles and frilly gills, have become very popular. But these friendly salamanders are more than just cute faces. Scientists are studying them because they might help us solve a big medical mystery: Can people someday grow back lost body parts, like an arm or a leg? 

<h2>Why Did Researchers Pick Axolotls? </h2>

In a groundbreaking <span>study</span> published on June 10 in Nature Communications, Monaghan's team utilized genetically engineered axolotls that glow in the dark to better understand this astonishing process. What makes axolotls so special? They have an incredible ability to regrow any part of their body, no matter how old they are. If they lose a leg, they can grow it right back. 

Even if their heart, lungs, or brain gets hurt, they can fix themselves! This amazing ability makes them champions among animals for their extreme healing powers. One of the long-standing questions in limb regrowth has been how cells "know" precisely which part of the limb to rebuild. For instance, if an axolotl loses its upper arm, it regenerates the entire arm. However, if the injury occurs further down the limb, only the lower arm and hand regrow. 

The key to this mystery appears to be a small molecule called retinoic acid, a compound related to vitamin A and commonly found in skincare products under the name retinol. This molecule acts like a GPS, providing cells with crucial positional information, guiding them on where they are on the body and what specific part needs to be rebuilt. 

<h2>How Retinoic Acid Directs Regrowth </h2>

The study's findings were compelling. When axolotls were given a drug that prevented the breakdown of retinoic acid, their limbs regenerated incorrectly, with an upper arm forming where a lower arm should have been. In contrast, axolotls not given the drug regrew their limbs normally. This strongly suggests that retinoic acid precisely instructs cells about their location and what structure to grow. 

While we are still a long way from growing human limbs, this study is a big step in that direction. The scientists believe this research could eventually help people. We all have the same basic genetic instructions for building limbs that we used when we were developing as babies. The challenge now is to figure out how to turn those same instructions back on later in life, which axolotls can do but humans can't yet. This is one of the oldest and most exciting questions in biology. Thanks to the growing interest in axolotls, especially among kids, these unique animals are helping to advance amazing scientific discoveries. It's quite surprising how popular axolotls have become, showing up everywhere from airports to toy stores.
