Teen Health 2 - 11 hours 30 min ago
A sweeping review from NYU Langone Health reveals that everyday exposure to plastics—especially during childhood—poses lasting risks for heart disease, infertility, asthma, and even brain development issues. These chemicals, found in packaging, cosmetics, and common household items, can disrupt hormones, ignite chronic inflammation, and lower IQ.

The Rise of the “Crunchy” Teen: Wellness Goes Viral

Teen Health & Wellness - 12 hours 29 min ago
More high schoolers are ditching soda and fast food in favor of “clean” eating, red light therapy, and fluoride-free toothpaste—and they’re documenting it all online. Self-described “crunchy” teen influencers are gaining tens of thousands of followers by promoting wellness routines and health advice aimed at their peers.

But health experts are worried. While some teens say these habits help them feel better, doctors and dietitians warn that unverified advice and obsession with “clean living” can trigger anxiety, shame, and even eating disorders. Bottom line: If you’re into health trends, stay curious—but don’t let sensational posts replace real science.

Smoking’s hidden gut bacteria trick may lead to new colitis treatments

Teen Health 2 - Fri, 2025-09-19 18:28
For decades, scientists have puzzled over why smoking makes Crohn’s disease worse but seems to protect people from ulcerative colitis. Now, researchers at RIKEN have discovered that smoking creates metabolites like hydroquinone that allow mouth bacteria—especially Streptococcus mitis—to settle in the gut. These bacteria spark an immune response that reduces inflammation in colitis but worsens Crohn’s. The findings open the door to new therapies using probiotics or targeted compounds that mimic smoking’s protective effects without its deadly risks.

Study Finds Teens Can Thrive After Bullying with the Right Support

Teen Health & Wellness - Mon, 2025-09-08 07:15
A new study from Lurie Children’s Hospital found that bullying during the teen years has a stronger link to anxiety and depression than when it happens in childhood. But it also showed that teens who feel supported and connected at school are more likely to recover emotionally.

That means your relationships—with friends, classmates, and trusted adults—really matter. Even if you’ve been through bullying, you have the power to heal and grow, especially when you surround yourself with people who truly see and support you.

One number at age 7 could predict how long you live

Teen Health 2 - Sun, 2025-09-07 16:51
Children with higher blood pressure as young as age 7 face a sharply increased risk of dying from cardiovascular disease by their mid-50s, according to a massive decades-long study. Researchers found that even moderately elevated readings, not just full hypertension, raised the danger, with risks climbing as much as 40–50%.

Cells “vomit” waste in a hidden healing shortcut that could also fuel cancer

Teen Health 2 - Sat, 2025-08-30 04:56
Scientists have uncovered a surprising new healing mechanism in injured cells called cathartocytosis, in which cells "vomit" out their internal machinery to revert more quickly to a stem cell-like state. While this messy shortcut helps tissues regenerate faster, it also leaves behind debris that can fuel inflammation and even cancer.

Progress in Orally Administered GLP-1 Diet Drugs

Teen Health & Wellness - Sat, 2025-08-23 09:42
The overwhelming popularity of glucagon-like peptide-1 (GLP-1) drugs such as Wegovy, Mounjaro, and Saxenda for weight loss has always been undercut by the fact that, with a single exception (Rybelsus, a diabetes drug taken orally), they’re only available in injectable form.

Now, drug manufacturer Eli Lily and Company has announced promising findings with its experimental GLP-1 pill orforglipron. In an 18-month clinical trial, around 60 percent of participants lost at least 10 percent of their body weight when taking orforglipron on a daily basis, and an average weight reduction of more than 12 percent of body weight occurred in people with obesity. The pill is intended to be an alternative to the company’s popular Zepbound weekly injectable.

Can a diet really ease lipoedema? Sunniva’s journey to pain relief and weight loss

Teen Health 2 - Sat, 2025-08-09 23:57
Sunniva Kwapeng struggled with lipoedema, a painful condition causing disproportionate fat accumulation, until finally being diagnosed in her 40s. An NTNU study found that a low-carb diet helped alleviate pain and resulted in more weight loss than a low-fat diet. Though compression garments provided relief, the overall treatment options for this poorly understood condition remain scarce.

Alarming New Data Shows That 1 in 3 Teens Has Prediabetes

Teen Health & Wellness - Mon, 2025-08-04 07:04
According to data from the U.S. Centers for Disease Control and Prevention’s most recent National Health and Nutrition Examination Survey, an estimated 1 in 3 teens between the ages of 12 and 17 had prediabetes in 2023. This is approximately 8.4 million, or 32.7 percent, of American adolescents, and a significant rise from 1 in 5 teens reported in 2020.

Prediabetes is when your blood sugar (glucose) levels are elevated beyond 70 to 99 milligrams per deciliter (mg/dL), but aren’t high enough for a diagnosis of type 2 diabetes, when levels are typically 200 mg/dL or higher. Prediabetes increases your risk not just for diabetes but other health conditions as well, including heart disease and stroke, so it’s essential to take steps to get prediabetes under control. Increasing your physical activity and losing a small amount of weight are both good ways to get started.

As AI Social Companions Grow in Popularity, Experts Advise Caution

Teen Health & Wellness - Mon, 2025-07-21 06:56
Teens are increasingly using customizable social companion apps like Replika, CHAI, and Character.AI to duplicate the experience of having a close platonic friend or even a romantic partner. According to recent research by Common Sense Media, 72 percent of survey participants between the ages of 13 and 17 have used an AI companion at least once, and more than 50 percent use them a few times a month. These apps have become so popular that investment firm ARK Invest projects that the AI social companion market may reach as much as $150 billion in revenue by the end of the decade.

But while AI social companions can serve a similar function as mental-health chatbots, providing support and encouraging reflection, their emphasis on unwavering validation runs the risk of doing so at the expense of a nuanced understanding of human relationships. As Dr. Jodi Halpern, a psychiatrist and professor at the UC Berkeley School of Public Health, notes, “We don’t want a perfectly smooth, frictionless thing as a relationship.” Despite some AI social companion apps being marketed to people as young as 13, the researchers at Common Sense Media recommend that teens avoid the apps until after they turn 18.

Three-person DNA IVF stops inherited disease—eight healthy babies born in UK first

Teen Health 2 - Fri, 2025-07-18 08:05
In a groundbreaking UK first, eight healthy babies have been born using an IVF technique that includes DNA from three people—two parents and a female donor. The process, known as pronuclear transfer, was designed to prevent the inheritance of devastating mitochondrial diseases passed down through the mother’s DNA. The early results are highly promising: all the babies are developing normally, and the disease-causing mutations are undetectable or present at levels too low to cause harm. For families once haunted by genetic risk, this science offers more than treatment—it offers transformation.
