Kids who consume energy drinks are more prone to mental health disorders, study finds
Energy drinks could pose a risk to young brains, according to new research.
Those who consumed energy drinks — which are intended to boost energy through the use of caffeine or other stimulants — were shown to have a higher risk of mental health issues, including attention-deficit hyperactivity disorder (ADHD), depression, anxiety and suicidal thoughts.
These findings stem from a review by Fuse, the Centre for Translational Research in Public Health at Teesside University and Newcastle University in the U.K.
CAFFEINE, THE WONDER DRUG? STUDY SUGGESTS MORE COFFEE COULD LOWER BODY FAT AND PREVENT TYPE 2 DIABETES
In the review, published in the journal Public Health, researchers looked at data from 57 studies of over 1.2 million children and young people from more than 21 countries who consumed energy drinks.
The researchers conducted this review as a follow-up to an initial review in 2016.

“We have found an even greater list of mental and physical health outcomes associated with children and young people consuming energy drinks,” lead author Amelia Lake, professor of public health nutrition at Teesside University, told Fox News Digital.
THESE ARE THE WORST DRINKS FOR YOUR HEALTH, ACCORDING TO NUTRITIONISTS
“We repeated [the review] only to find an ever-growing evident space that suggests the consumption of these drinks is associated with negative health outcomes.”
The caffeine content of energy drinks ranges from 50 mg to 505 mg per serving, compared to 90 mg in 8.45 ounces of coffee, 50 mg in 8.45 ounces of tea and 34 mg in 16.9 ounces of soda, the researchers noted.

Based on the findings, the researchers and other U.K. health organizations are calling for the government to ban sales of energy drinks to children under age 16.
“This evidence suggests that energy drinks have no place in the diets of children and young people,” said Lake.
“Policymakers should follow the example from countries that have placed age restrictions on their sales to children.”
Experts weigh in
Erin Palinski-Wade, a New Jersey-based registered dietitian, was not involved in the new research but said its findings did not surprise her.
“Energy drinks are not a safe choice for children and no safe guidelines have been established for caffeine consumption in those under the age of 18,” she told Fox News Digital.
“This evidence suggests that energy drinks have no place in the diets of children and young people.”
Caffeine has a half-life of six to eight hours, she noted — which means it takes that long for it to leave the system.
“Even small amounts of caffeine can impact quality and quantity of sleep, and poor sleep is directly correlated with a decline in both mental and physical health — in adults as well as children,” Palinski-Wade noted.

“A lack of quality sleep can lead to impaired cognitive functions such as decision-making, conflict resolution, working memory and learning, along with changes in behavior, mood and an increased risk of depression.”
Insufficient sleep can also negatively impact a child’s brain development, she added, which can lead to learning problems and more frequent negative emotions.
“A lack of sleep can also impact memory and concentration, making it harder to perform academically, especially if sleep is chronically interrupted,” the expert said.
COFFEE VS. TEA: WHICH DRINK IS ‘BETTER’ FOR YOU?
Even in healthy adults, daily caffeine intake should not exceed 400 mg per day, according to the U.S. Food and Drug Administration.
“With an average energy drink containing 200 mg of caffeine or more, it can be easy to exceed this intake, even as an adult,” said Palinski-Wade. “For children, these drinks are best avoided.”

Dr. Alex Dimitriu, a psychiatrist and sleep doctor who is also the founder of Menlo Park Psychiatry & Sleep Medicine in California, was not involved in the study but offered his expert input.
“The concern with any exogenous substance in children under the age of 21 is that the human brain is not done forming until people are about the age of 26,” Dimitriu told Fox News Digital.
“For this reason, substance use, including energy drinks, can markedly alter development, and certainly build patterns that resemble drug-seeking behavior as children look to external ‘fixes,’ for possible mood, focus or energy symptoms.”
DRINKING COFFEE ON A DAILY BASIS CAN EXTEND YOUR LIFE: NEW STUDY
The impact of energy drinks on sleep is particularly concerning, as the effect can be “bidirectional,” noted Dimitriu.
“Poor sleep may lead kids to use energy drinks, and energy drinks can lead to poor sleep,” he said.
“Because sleep is essential for brain development, anything that diminishes sleep quality can affect cognitive and emotional performance, both in the long and short term.”

Many people with undiagnosed ADHD also tend to gravitate toward stimulants, energy drinks and caffeine, Dimitriu pointed out — “so it is essential to also understand what the motivation is for children using these substances, and to treat underlying causes.”
“Lack of sleep is a huge cause of emotional and cognitive disturbance, for both adults and children in the U.S.,” he added.
Potential limitations
The review did have some limitations, the researchers acknowledged.
Some of the included studies were lacking in quality and design, while others did not clearly define the ages of the participants. They also do not prove that energy drinks cause the observed health issues, the journal entry stated.

“We accept the evidence is from mostly cross-sectional studies, exploring association rather than causation,” Lake told Fox News Digital.
“Experimental studies to establish causation have both ethical and feasibility issues.”
Industry associations and regulators react
In response to the study, a spokesperson from the American Beverage Association (ABA) provided a statement to Fox News Digital.
“It’s important to note that neither study found that energy drinks cause sleep problems or any health issues and that the authors acknowledge there may be other reasons for their findings,” the American Beverage Association said in a statement to Fox News Digital. (iStock)
“Energy drinks have been enjoyed by billions of people around the world for more than 30 years and are recognized by government food safety agencies worldwide, including the U.S. Food and Drug Administration, Health Canada and the European Food Safety Authority, as safe for consumption,” the group said.
“It’s important to note that neither study found that energy drinks cause sleep problems or any health issues — and that the authors acknowledge there may be other reasons for their findings.”

The ABA spokesperson also noted that a mainstream energy drink contains 80mg of caffeine per 8 oz. serving — “which is approximately half the amount of caffeine found in a similar-sized serving of coffeehouse coffee.”
The association added, “America’s leading energy drink manufacturers voluntarily go beyond all federal requirements when it comes to responsible labeling and marketing practices, including displaying total caffeine content from all sources and to not promote excessive or unduly rapid consumption of their drinks.”
“The FDA is reviewing the findings of the paper,” the agency told Fox News Digital in a statement. (iStock)
When contacted for comment, the U.K. Food Standards Agency (FDA) directed Fox News Digital to its guidelines for caffeine consumption by children and teens, as specified below.
“Single doses of caffeine up to 3mg/kg body weight (bw) and daily intakes of caffeine up to 3mg/kg bw do not raise safety concerns. For a 10-year-old child weighing 30kg, this would work out to around 90mg of caffeine. Even a small can of energy drink can contain up to 200mg of caffeine and exceed the recommended daily intake for a child.”

Fox News Digital also reached out to the U.S. Food and Drug Administration (FDA) requesting comment.
“In general, the FDA does not comment on specific studies, but evaluates them as part of the body of evidence to further our understanding about a particular issue and assist in our mission to protect public health,” an agency spokesperson said. “The FDA is reviewing the findings of the paper.”

Major cannabis study finds little proof for popular medical claims, flags big dangers
NEWYou can now listen to Fox News articles!
Cannabis has been linked to some significant medical benefits, but recent research calls those into question.
A major new analysis published in JAMA examined more than 2,500 scientific papers from the last 15 years, including other reviews, clinical trials and guidelines focused on medical marijuana.
“While many people turn to cannabis seeking relief, our review highlights significant gaps between public perception and scientific evidence regarding its effectiveness for most medical conditions,” Dr. Michael Hsu of University of California – Los Angeles (UCLA) Health Sciences, author of the study, said in a press release.
Many medical claims about cannabis are not supported by strong scientific evidence, according to a comprehensive review published in JAMA. (iStock)
The researchers — led by UCLA with contributions from Harvard, UC San Francisco, Washington University School of Medicine and New York University — set out to determine how strong the research is on the effectiveness of medical cannabis and to offer evidence-based clinical guidance.
MYSTERIOUS MARIJUANA-LINKED VOMITING DISORDER GETS OFFICIAL WHO CODE AS ER CASES JUMP
The review found that evidence supporting most medical uses of cannabis or cannabinoids is limited or insufficient, the release stated.
“Whenever a substance is widely used, there is likely to be a very wide set of outcomes,” Alex Dimitriu, MD, double board-certified in Psychiatry and Sleep Medicine and founder of Menlo Park Psychiatry & Sleep Medicine, told Fox News Digital.
“Cannabis is now used by about 15 to 25% of U.S. adults in the past year, for various reasons ranging from recreational to medicinal. This study points to the reality that this widely used substance is not a panacea,” said Dimitriu, who was not involved in the study.
There are very few conditions for which cannabinoid therapies have clear, well-established benefits backed by high-quality clinical data, according to the researchers.
HEAVY DRINKERS CUT ALCOHOL USE BY NEARLY 30% AFTER ADOPTING ONE NEW HABIT, STUDY FINDS
The strongest evidence supports FDA-approved cannabinoid medications for treating specific conditions, including HIV/AIDS-related appetite loss, chemotherapy-induced nausea and vomiting, and certain severe pediatric seizure disorders.
The review identified significant safety concerns, with high-potency cannabis use among young people linked to higher rates of mental health issues. (iStock)
For many other conditions that are commonly treated with cannabis — such as chronic pain, insomnia, anxiety or post-traumatic stress disorder — evidence from randomized trials did not support meaningful benefit.

The analysis also examined safety concerns — in particular, how young people using high-potency cannabis may be more likely to suffer higher rates of psychotic symptoms and anxiety disorder.
Daily inhaled cannabis use was also linked to increased risks of coronary heart disease, myocardial infarction (heart attack) and stroke when compared with non-daily use.

Based on these findings, the review emphasizes that clinicians should weigh potential benefits against known risks when discussing cannabis with patients.

The authors suggest that clinicians screen patients for cardiovascular risk, evaluate mental health history, check for possible drug interactions and consider conditions where risks may outweigh benefits.

They recommend open, realistic conversations and caution against assuming that cannabis is broadly effective for medical conditions.

“Patients deserve honest conversations about what the science does and doesn’t tell us about medical cannabis,” Hsu said.
This article is a narrative review rather than a systematic review, so it did not use the strict, standardized methods that help reduce bias in how studies are selected and evaluated, the researchers noted.

The review notes further limitations, including that some evidence comes from observational research rather than randomized trials, which means it cannot establish cause and effect.
The trial results also may not apply to all populations, products or doses.

Always running late? The real cost to your relationships may surprise you
NEWYou can now listen to Fox News articles!
Chronic lateness is known to be a common annoyance, often leading to strain within relationships, experts have confirmed.
And for some people who struggle to be on time, the reasons may go far beyond poor planning.
Psychotherapist and author Jonathan Alpert told Fox News Digital that chronic lateness often stems from a combination of psychological patterns and neurobiological factors that people may not realize are influencing them.
ALWAYS RUNNING LATE? A MENTAL HEALTH CONDITION COULD BE TO BLAME, EXPERTS SAY
“For some people, it’s personality-driven. They’re distractible, optimistic about how long things take, or simply not tuned into the impact on others,” the New York-based expert said.
For others, the issue stems from neurobiological differences that affect how the brain manages time.

That can make it harder to estimate how long tasks take or to transition from one activity to the next, leading to chronic lateness, according to Alpert.
Impact on relationships
In addition to disrupting schedules, chronic lateness may also strain relationships and create tension.
“Lateness erodes trust. Over time, it sends the message that someone else’s time is less important, even if that’s not the intent,” Alpert noted.
7 SIGNS YOU MIGHT HAVE ADHD AND WHAT STEPS TO TAKE
Lateness can also become an issue in the workplace, where repeated delays can undermine teamwork and harm a person’s reputation.
These patterns are common among people with ADHD, who often experience what is known as “time blindness,” making it difficult to recognize how quickly minutes pass or how long tasks truly take.
“Adding 10 to 15 minutes of buffer between activities reduces the frantic rushing that leads to chronic lateness.”
ADHD is strongly associated with executive-function difficulties, which are the skills needed to stay organized, plan ahead and focus on essential details, according to the Attention Deficit Disorder Association.
When these abilities are weaker, it becomes more challenging to gauge time, follow a schedule and meet deadlines, which can impact personal and professional relationships, experts agree.

Underlying patterns
Anxiety, avoidance and perfectionism are patterns that Alpert most often sees in people who tend to run late, he noted.
“Many chronically late individuals don’t intend to be disrespectful. They’re overwhelmed, anxious or trying to squeeze too much into too little time,” he said.

These emotional patterns often show up in different ways. For some, anxiety can make it difficult to begin even simple tasks, pushing everything behind schedule before the day has even started, according to Alpert.
For others, the struggle happens in the in-between moments. Shifting from one activity to another can feel surprisingly uncomfortable, so they linger longer than intended and lose time without noticing.
Anxiety is a major factor behind why some people have trouble being on time, according to experts. (iStock)
Others may get caught up in the details, as perfectionism keeps them adjusting or “fixing one more thing” as the minutes slip away, Alpert said.

Another major factor, the expert shared, is that many people simply misjudge how long tasks take. Their internal sense of time is often inaccurate, which leads them to assume they can fit far more into a day than is realistically possible.
‘Time audit’
Alpert often recommends that his clients perform a simple “time audit,” where they track how long they think a routine task will take and then time it in real life. This can help them rebuild a more accurate internal clock, he said.

“Adding 10 to 15 minutes of buffer between activities reduces the frantic rushing that leads to chronic lateness,” he said.

Despite the challenges lateness can create, Alpert said people don’t have to be stuck with these habits forever. With the right support and consistent strategies, meaningful change is possible.

“Strong routines, alarms, checklists and accurate time estimates compensate for traits that don’t naturally disappear,” he added.
People who find that lateness is affecting their everyday life and relationships may benefit from discussing their concerns with a healthcare provider or mental health professional.

Holiday heart attacks rise as doctors share hidden triggers, prevention tips
NEWYou can now listen to Fox News articles!
The holidays are known to be a source of stress, between traveling, preparing for family gatherings and indulging in lots of food and drinks.
The uptick of activity can actually put a strain on the heart, a phenomenon known as “holiday heart syndrome.”
Cardiothoracic surgeon Dr. Jeremy London addressed this elevated risk in a recent Instagram post, sharing how heart attacks consistently rise around the holidays.
TREATING GUM DISEASE COULD REDUCE RISK OF HEART ATTACKS AND STROKES, STUDY SUGGESTS
“Every year, like clockwork, we see a spike in heart attacks around Christmas and New Year’s,” the South Carolina-based surgeon said. “In fact, Christmas Eve is the highest-risk day of the year.”
This is due to a shift in behavior, specifically drinking and eating too much, moving less and being stressed out, according to London. “Emotional stress, financial stress, the increased pace of the holidays, increased obligations,” he listed.
Cold weather also causes vasoconstriction (narrowing of blood vessels), according to London, which increases the risk of plaque rupture and the potential for heart attack.
CUTTING OUT ALCOHOL AND MEDICATING SOONER COULD PREVENT ‘SILENT KILLER,’ EXPERTS SAY
Dr. Glenn Hirsch, chief of the division of cardiology at National Jewish Health in New York, noted in an interview with Fox News Digital that holiday heart syndrome typically refers to the onset of an abnormal heart rhythm, or atrial fibrillation.
This can happen after an episode of binge-drinking alcohol, Hirsch said, which can be exacerbated by holiday celebrations.
Binge-drinking at any time can drive atrial fibrillation, a cardiologist cautioned. (iStock)
“It’s often a combination of overdoing the alcohol intake along with high salt intake and large meals that can trigger it,” he said. “Adding travel, stress and less sleep, and it lowers the threshold to go into that rhythm.”
The biggest risk related to atrial fibrillation, according to Hirsch, is stroke and other complications from blood clots. Untreated atrial fibrillation can lead to heart failure after a long period of time.

“The risk of atrial fibrillation increases with age, but also underlying cardiovascular disease risk factors increase the risk, such as high blood pressure, obesity, diabetes, sleep apnea and chronic kidney disease,” he added.

The expert recommends avoiding binge-drinking, overeating (especially salty foods) and dehydration, while managing stress levels and prioritizing adequate sleep.
“Don’t forget to exercise,” he added. “Even getting in at least 5,000 to 10,000 steps during the holiday can help lower risk, [while] also burning some of the additional calories we are often consuming around the holidays.”

London agreed, stating in his video that “movement is medicine” and encouraging people to get out and move every day.

“Prioritize sleep and mindfulness,” he added. “Take care of yourself during this stressful time.”
London also warned that many people delay having certain health concerns checked out until after the holidays, further worsening these conditions.
