Many people believe that the modern-day skincare trends are a scam made by the big pharma companies who wish to make more money. This is a recent trend of ‘Anti-Aging’ skincare that keeps yourself on toes for the innate need for women to stay ‘young’ if they wish to be desirable. The beauty industry, in a way, feeds on such societal-made insecurities. But the recent rise in the trend has taken a different turn. While before people did it before to look prettier or fairer, now people are looking at this skincare routine as a way of taking care of themselves rather than doing to match someone else's beauty standards. This is why, this trend has resurfaced in the skin care community. This is the blue light routine.

In today's digital age, where we spend countless hours looking at screens, from phones and tablets to laptops. This constant screen time exposes us to blue light, which research suggests can have negative effects on our skin. It also leads to premature aging and dark spots. The screens also leads to stress, which could further cause harm to skin. While ditching our devices isn't realistic, a growing number of skincare products claim to protect against blue light. But do these products actually work?

What is Blue Light Skincare?

You can find many skincare products that say they protect against blue light, like sprays, creams, gels, and sunscreens. Some promise to undo the damage blue light might cause, while others try to prevent it in the first place. Blue light sunscreens are special because they protect against both the sun's UV rays and blue light. This is what regular sunscreens don't do very well. Regular sunscreens, whether they use chemicals or minerals, don't block blue light as effectively.

However, tinted sunscreens are different. Tinted sunscreens with SPF 30 or higher can protect your skin from blue light, as well as UVA and UVB rays from the sun. This is because of the coloring in the tint. Some newer sunscreens also have special ingredients that help protect against visible light, including blue light. While scientists are still learning about how blue light affects skin, many skin doctors have found it to be helpful for skin.

What is Blue Light and Why Might It Be a Problem?

Blue light comes from screens, TVs, and even the sun. While we used to worry mostly about how it affects our eyes and sleep, now we're learning it might also affect our skin. Some studies show that too much blue light can damage skin cells and speed up aging, leading to wrinkles and uneven skin tone. It can also cause dark spots on the skin. This happens because blue light can cause something called "oxidative stress" in the skin, which is linked to aging. It leads to dead skin cells. Blue light goes deeper into the skin than the sun's UV rays and can make skin cells produce more pigment, causing dark spots. It's important to know that not all blue light is bad. There is a difference between the blue light that comes out of the screens and the blue light that is used from a certain blue light wavelength as a therapy. The latter is used by doctors to treat acne and some skin cancers.

The US Food and Drug Administration approved leucovorin for cerebral folate deficiency in the receptor 1 gene, a rare genetic condition. However, last year, in September, this drug was noted as the possible and potential treatment for children with autism. The Trump administration noted that Tylenol may be triggering autism in children when is consumed by pregnant mothers. The same conference touted this drug as a potential treatment, while not enough scientific evidence was there to support the claim. Yet, many parents looked for the prescription to support their children.

Health and Me also reported a story of a mother who looked for the drug for her three-year-old son. Another case of four-year-old Jose Morales-Ortiz, who struggled to speak even two-word sentences. As per a CNN report, he was diagnosed with severe autism and rarely responded when someone called his name.

However, something changed, in early summers, he began telling his guardian Keith Joyce about the conversation with his classmates and answering follow-up questions. For Keith, it was a moment of joy. It was also the first time Keith had a conversation with him.

Joyce believes the change began after Jose started taking leucovorin, a medication originally approved to reduce the side effects of certain chemotherapy drugs. Now, researchers are investigating whether the drug may help some children with autism—particularly those with a condition known as cerebral folate deficiency.

However, scientists caution that while early studies are promising, the evidence is still limited and the treatment remains controversial.

What Is Leucovorin?

Leucovorin, also known as folinic acid, is a biologically active form of vitamin B9 or folate. Unlike standard folic acid supplements, it does not require the body to convert it into an active form before it can be used. Due to this very feature, it can bypass certain metabolic steps and deliver folate more directly to the cells.

It is a high-dose B vitamin, which is commonly used as a treatment to counteract the side effects of chemotherapy. It has been approved by the FDA for cerebral folate deficiency in the receptor 1 gene. The disease is rare and fewer than 50 cases have been identified worldwide. FDA Commissioner Dr Marty Makary called this approval "a significant milestone" for patients with the condition.

Doctors have used the drug for several purposes, which also include:

• Reducing toxic side effects of chemotherapy
• Enhancing the effectiveness of certain cancer treatments
• Treating folate deficiency caused by medications or disease

Recently, scientists began exploring whether leucovorin could also help certain neurological conditions.

What Role Does Folate Play In Brain Development?

Folate is essential for brain development and neural function.

It helps in:

• DNA synthesis and repair
• Formation of neurotransmitters
• Development of neural connections
• Cell growth in the developing brain

During pregnancy, folate is so critical that many countries fortify foods with folic acid to prevent birth defects such as neural tube defects.

However, in some children, the issue may not be a lack of folate in the diet—but a problem with how folate reaches the brain.

What Happens In Cerebral Folate Deficiency?

In 2005, researchers discovered an unusual phenomenon in some children with developmental disorders.

Although their blood folate levels were normal, their brain folate levels were extremely low.

The reason appeared to be autoantibodies—immune proteins that mistakenly attack the body’s own tissues. In this case, the antibodies targeted folate receptor alpha, the protein responsible for transporting folate across the blood-brain barrier.

When these receptors are blocked:

• Folate cannot enter the brain efficiently
• Neural development may be affected
• Symptoms similar to autism may appear

This condition is called cerebral folate deficiency.

Researchers also developed a diagnostic blood test called the Folate Receptor Autoantibody Test (FRAT) to detect these antibodies.

How Does Leucovorin Work?

It could work in such a case because it is able to bypass the blocked folate receptors. It does not rely on the usual transport system and is able to enter the brain through alternative transport pathways, which allow neurons to access the folate they need. Scientists also believe that this could improve neurotransmitter production, support neural communication, and enhance brain metabolism in certain children.

Some clinical studies have suggested that leucovorin may improve language and communication skills in certain children with autism.

In small trials:

• Some children showed improvements in expressive speech
• Others improved in receptive language and social communication
• Benefits appeared strongest in children with folate receptor antibodies

However, the results have been mixed.

Some studies have found only modest improvements, and large placebo-controlled trials—considered the gold standard in medical research—are still lacking.

Because autism is a complex spectrum condition with many biological pathways involved, researchers emphasize that no single medication is likely to work for every child.

The growing interest in leucovorin reflects a broader shift in autism research: looking for biological subtypes of the condition that might respond to targeted treatments.

If cerebral folate deficiency proves to be one of those subtypes, leucovorin could become an important therapy for a specific group of children.

But scientists emphasize that autism is highly complex. “There’s no autism pill,” many researchers say.

California made it news for a disease that has no vaccination. This is the human metapneumovirus or the HMPV. While some of the symptoms of this virus are similar to that of any common cold or influenza like cough, fever, nasal congestion or shortness of breath, there are several symptoms that are unique to the disease.

Unique Symptoms Of HMPV - The Virus Without Vaccine

Unlike mild common colds, HMPV often presents with a high-grade fever, particularly in children. Some of the other symptoms also include persistent coughing, including dry or productive and may persist for a long duration.

Furthermore, it could cause wheezing, difficulty in breathing, which could also lead to severe lower respiratory tract illness like bronchiolitis or pneumonia. In children and older adults, it could also cause severe or often fatal bronchiolitis or rapid-onset pneumonia.

In infants, it could also exhibit irritability, poor feeding, or dehydration.

Other symptoms, which could resemble common cold like symptoms are:

• cough
• fever
• sore throat
• runny or stuffy nose
• body ache
• headache

What Is Happening In California?

As per the public database WasterwaterScan Dashboard, high levels of HMPV were detected across Northern California cities. The highest levels were reported in Redwood City, whereas elevated levels were found in San Francisco Bay Area and Napa's Wine Country. What's more dangerous is that this virus is without a vaccine.

The good news is that in other parts of country HMPV remains lower. However, the Centers for Disease Control and Prevention (CDC) noted that data from October 2025 shows the cases are trending up, especially during winter and spring.

Dr. Matthew Binnicker, director of the Clinical Virology Laboratory at Mayo Clinic, as reported by The Independent said, "In the late winter, early spring, it can account for five percent to 10 percent of all the respiratory infections that we diagnose in the United States. So it's definitely out there." Experts explain that other viruses like HMPV or influenza get a chance when COVID is quieter.

What Is HMPV - The Virus Without Vaccine?

HMPV was first discovered in 2001 and is part of the Pneumoviridae family along with the Respiratory syncytial virus (RSV).

HMPV most likely spreads from an infected person to others through:

• the air by coughing and sneezing
• close personal contact, such as touching or shaking hands
• touching objects or surfaces that have the viruses on them, then touching the mouth, nose, or eyes

In the US, HMPV circulates in predictable patterns each year, typically beginning in winter and lasting through spring.

Who Are At Risk Of HMPV?

People at risk include:

• elderly people
• children
• people with comorbidities

"The HMPV is not deadly, and there is no evidence of mortality or a severe transmission rate," former Indian Council of Medical Research (ICMR) scientist, Dr. Raman Gangakhedkar, told IANS, during the virus's outbreak in India in 2025.

“The virus may cause pneumonitis-like illness, but the mortality rates are almost unknown so far. HMPV has a global prevalence of about 4 per cent,” he added.

Smoking has been long recognized as one of the worst habits a person can have, and Dr Jeremy London agrees with this statement. Dr. London, a cardiovascular surgeon, in a recent interview with Mel Robbins revealed that his number one advice as a heart doctor is to avoid smoking.

“I cannot come up with one single thing that does as much damage to every organ in the body as smoking cigarettes. And look, it's incredibly addictive and I know that and I pass no judgment because I know how difficult it is.”

He explained that in his practice he has dealt with chronic smokers for years and still believed that it is the single most dangerous thing one can do to themselves.

How Does Smoking Affect Other Organs?

Emphasizing how this one habit affects all organs in our body, Dr London mentioned the well-known link between lung cancer and smoking.

However, there are many more chronic diseases associated with the rest of the body that can develop due to smoking apart from lung conditions, according to the American Lung Association.
