Published on Leave a comment on Morning Coffee or Tea Improves A Person’s Mood

Many of us absolutely desire and need a caffeine containing beverage such as coffee or tea in the morning, and find it difficult to function without it. So, findings from a recent study shouldn't surprise us: morning coffee or other caffeinated drink boosts a person's mood .

Also not surprising: the improved mood was strongest in the first 2 1/2 hours after awakening. They also confirmed that a person can have caffeine withdrawal symptoms, which go away after drinking caffeinated beverages such as coffee or tea.

Duh...of course. Every person that drinks coffee or tea in the morning knows this. But at least a study has now confirmed this.

From Medical Xpress: Morning coffee boosts mood significantly, study finds

People who regularly consume caffeine are usually in a better mood after a cup of coffee or another caffeinated drink—an effect that is much more pronounced in the morning than later in the day. This finding comes from a new study by researchers at Bielefeld University and the University of Warwick, published in the journal Scientific Reports. Participants reported feeling significantly happier and more enthusiastic on those mornings compared with other days at the same hour when they had not yet had coffee. ...continue reading "Morning Coffee or Tea Improves A Person’s Mood"

Published on Leave a comment on Effects of Stopping Weight Loss Drugs

Weight loss drugs (e.g., Ozempic) are very, very popular these days. But what happens when you stop taking the prescription drugs? A recent review of 11 global studies found that the drugs work well while being used, and led to significant weight loss. But within 2 months of stopping the medications, significant regaining of weight starts.

The researchers noted that the studies found that regaining of weight started by 8 weeks after the medications were stopped, and that weight gains tended to plateau about 20 weeks later, but continued as long as the studies lasted (even 1 year later). Yikes!

From Science Daily: What really happens to your body when you stop weight loss drugs like Ozempic

Patients prescribed drugs to help them lose weight may experience a rebound in weight gain after halting their prescription, finds a meta-analysis published in BMC Medicine. The study, which analyses data for patients receiving weight loss drugs across 11 randomised trials, suggests that while the amount of weight regain varies depending on the specific drug, there is a broad trend in associated weight regain after the course of medication concluded. ...continue reading "Effects of Stopping Weight Loss Drugs"

Published on Leave a comment on Lifestyle Changes That Benefit the Aging Brain

As people age, they frequently start wondering what they can do to prevent memory and thinking problems, and especially dementia. The good news is that several large studies found that there are a number of lifestyle changes that one can do to have a healthier (memory! thinking!) brain in later years. Even if you are already in your 60s and 70s.

The evidence points to diet (e.g., Mediterranean style diet, ), exercise, and socializing being all important for brain health. In fact, it can result in keeping brains several years "younger" than in those with unhealthy lifestyles. Also, studies find that challenging your brain by learning something new, such as learning a new language or musical instrument or online cognitive training, is beneficial for the brain.

Adopting a lifestyle that promotes brain health is so very important, because it is NORMAL that as we age, there are brain changes, including brain shrinkage (volume of the brain). Therefore you want to slow down or delay these age related changes as much as possible. Researchers feel that adopting these lifestyle changes are so effective that they should be medically prescribed.

Excerpts from NPR: Trying to keep your brain young? A big new study finds these lifestyle changes help

Scientists have unveiled the strongest evidence yet that a combination of diet, exercise and brain training can improve thinking and memory in older Americans.

A study of more than 2,100 sedentary people in their 60s and 70s found that those who spent two years on the intensive regimen not only improved their mental abilities but appeared to reduce the usual declines associated with aging. ...continue reading "Lifestyle Changes That Benefit the Aging Brain"

Published on Leave a comment on The Erasing Of Climate Science

Going forward, will we even know what is going on in the atmosphere regarding carbon dioxide and other greenhouse gases? Will there be any data collected and scientific evidence regarding climate change? As you may have heard, all climate change research and knowledge is being eliminated and erased. The words climate change and greenhouse gases  are not to be spoken or written according to the US government.

But even so, what is shocking to scientists is that 4 prestigious observatories operated by the US for decades, and which were instrumental in documenting the increase in greenhouse gases, are to be closed down by the US government. The Mauna Loa Observatory in Hawaii has been measuring CO2 levels in the air for over 65 years!

And yup, it has been documenting the steady increase, year after year, of CO2. Due to burning of oil, gas, and coal. In 65 years CO2 levels have increased from 316 ppm to more than 430 parts per million. This is a huge increase!

An article in The Conversation explains why carbon dioxide is so important - how it's needed for a habitable Earth, but too much carbon dioxide is bad.

"The reason carbon dioxide is so important is that this molecule has special properties. Its ability to trap heat alongside other greenhouse gases means Earth isn’t a frozen rock. If there were no greenhouse gases, Earth would have an average temperature of -18°C, rather than the balmy 14°C under which human civilisation emerged.

The greenhouse effect is essential to life. But if there are too many gases, the planet becomes dangerously hot. That’s what’s happening now – a very sharp increase in gases exceptionally good at trapping heat even at low concentrations."

From NY Times: After 7 Decades of Measurements From a Peak in Hawaii, Trump’s Budget Would End Them

More than 11,100 feet above sea level, surrounded by nothing but black rocks, white clouds and blue sky, the Mauna Loa Observatory is in a Goldilocks spot for studying the atmosphere.

The air that swirls around the isolated outpost located on a Hawaiian volcano is a mix from all over the Northern Hemisphere. That makes it one of the best places to measure greenhouse gases in the atmosphere. It is indispensable to scientists around the world. ...continue reading "The Erasing Of Climate Science"

Published on Leave a comment on A Walk In the Woods Is Good For Us

After the recent incredibly hot and steamy week, it is nice to read something positive about nature. A recent review of studies found that taking a walk in a forest is good for us in a number of ways: reduces stress, improves our mood, and good for our physical health (e.g., lowers blood pressure, benefits immune system). It shouldn't be a surprise that walking in nature is soothing.

A recent presentation at the American Psychiatry Association (APA) annual meeting discussed a review of 15 studies looking at the health benefits of walking in a forest. While the length of time varied in each study, it was generally 2 walks per week, 2 hours at a time. The health benefits were so clear that the researchers said such walks are therapeutic and could be viewed as forest therapy.

While most of us call it a walk in nature or a walk in the woods, the Japanese refer to it as shinrin yoku, which translates as forest bathing. They have long-recognized the health benefits of shinrin yoku, and doctors prescribe forest bathing to stressed people to "recharge and recover". Some doctors in the US also recommend prescribing walks in nature (nature prescribed) - Park Rx America

From Medscape: Growing Evidence for the Healing Power of ‘Forest Therapy’

Spending time in a forest — an experience known as Shinrin-Yoku, or “forest bathing,” in Japan where the practice originated — can lift mood, reduce stress, and promote physical health, a new literature review suggested.

Most of the studies included in the review reported moderate to strong effect sizes, using validated measures such as the Profile of Mood States (POMS) and physiological indicators like blood pressure. ...continue reading "A Walk In the Woods Is Good For Us"

Published on Leave a comment on New Cookware That Falsely Advertises As Nontoxic

Some companies advertise so-called "nontoxic cookware" and "nontoxic nonstick cookware", with "new and improved" finishes, or coatings, or materials used. But are the ads truthful?

The Guardian published an investigation into the the matter. Uh-oh. They found evidence of toxic chemicals used (lead, mercury, titanium dioxide, etc.) by companies advertising their products as "nontoxic". Some of the cookware advertises itself as a nontoxic ceramic cookware, but it's actually "quasi-ceramic" and containing hidden ingredients (which the companies call proprietary ingredients).

Also, keep in mind that there are no actual regulations or legal definitions of what "nontoxic" or "ceramic" means. Some of the cookware contains lead, yet there are no federal limits for lead in ceramic cookware. The problems go on and on.

In other words, buyer beware. A safer alternative is to use traditional stainless steel, glass (e.g., Pyrex), and cast iron cookware

Excerpts from The Guardian: Toxic truth? The cookware craze redefining 'ceramic' and 'nontoxic'

The cookware industry has entered a golden age, largely driven by the wild success of a new generation of “nontoxic” and “nonstick” designer ceramic pans backed by stars including Selena Gomez, Stanley Tucci and Oprah Winfrey.

But the pans are probably not “nontoxic” some independent testing and research suggests. Nor are they even “ceramic” – at least not in the way the public broadly thinks of ceramics. Now, regulators are investigating some of the pan sellers’ claims. ...continue reading "New Cookware That Falsely Advertises As Nontoxic"

Published on Leave a comment on Heat Is A Bigger Killer Than Other Weather Disasters

We are saddened when hearing about persons dying in floods, tornadoes, and other natural weather disasters. The numbers seem so high. But...it turns out the biggest killer each year is heat. Extreme heat kills more people most years than hurricanes, floods, and tornadoes combined.

Extreme heat events are on the rise globally (yup, climate change) and so the number of people dying are increasing. For example, the recent heat wave across Europe, when temperatures surged higher than 100 degrees Fahrenheit, is thought to have killed thousands of people. Especially since in many of the areas hit by the extreme heat people don't have air conditioning in their homes.

A quick analysis of heat-related deaths by researchers at the Imperial College London found that human-induced climate change intensified the European heatwave between June 23 and July 2, 2025 and tripled the number of heat-related deaths. They found that about 2300 people may have died from the extreme heat over the 10 day period across the 12 European cities they looked at, but that over all Europe there could have been tens of thousands of deaths. People over 65 accounted for a majority (88%) of the deaths.

Each year in the US, heat kills more people than any other type of extreme weather.

The following article was written last year, but it still applies since each year is getting hotter. Note that 2024 was hotter than 2023, which was the final year of the heat-related death analysis. NY Times: Heat Deaths Have Doubled in the U.S. in Recent Decades, Study Finds

As dangerous heat bears down on the central and eastern United States this week, a new study shows heat-related deaths across the country are on the rise. ...continue reading "Heat Is A Bigger Killer Than Other Weather Disasters"

Published on Leave a comment on Chemicals of Concern Found In the Bodies of Young Children

Once again, those wondering about the chemicals lurking inside us have bad news. In a long-running study, researchers tested 201 young children (aged 2 to 4 years old) and found that all of them have many dangerous chemicals ("chemicals of concern") in their bodies. Some of the chemicals were in higher levels in the children than in their mothers during pregnancy.

In this study pregnant women from 4 states had their urine analyzed, and later the urine of their children when they were 2 to 4 years old. The testing of blood and urine from a person and looking for certain chemicals is called biomonitoring.

The researchers only looked for  111 chemicals and found that at least 5 children had 96 of them detected in their urine. Over 50% of the children had 48 chemicals detected. Thirty four of the chemicals were detected in over 90% of the children. But keep in mind that they only looked for a limited number of chemicals. Some of the chemicals found are not being monitored in adult biomonitoring. Many chemicals we are routinely exposed to, such as the common pesticide glyphosate (found in many non-organic foods) were not looked at.

One trend the researchers found is that levels of 2,4-D (pesticide used as a herbicide or weed-killer) are trending upwards over time. This is because 2,4-D is commonly used as a weed-killer on lawns (including Feed and Weed) and elsewhere, but it is also used on genetically modified crops.

The 111 chemicals tested for are from the foods and beverages children (and adults) ingest, personal care products (e.g., soap, lotion), the chemicals used in the home (e.g., pesticides, cleaning products) or chemicals outgassing from products used in the home (e.g., from non-stain synthetic rugs, plastic toys, vinyl floors). Children are exposed to the chemicals when they breathe indoor and outdoor air, eat food, touch surfaces or objects - both indoors and outdoors.

Bottom line: Eat as many organic foods as possible (pesticides such as 2,4-D and glyphosate are not allowed in organic food production). Additional tips: Lifestyle tips for avoiding harmful chemicals.

Excerpts from Science Daily: Researchers tested 200 toddlers — 96 chemicals were lurking in their bodies

A national study published in Environmental Science & Technology finds children aged 2 to 4 years in the United States are routinely exposed to a broad range of potentially harmful chemicals. Many of the chemicals the researchers identified are not routinely monitored and may pose health risks. ...continue reading "Chemicals of Concern Found In the Bodies of Young Children"

Published on Leave a comment on Diabetes and Artificial Sweeteners

For years I heard health care providers recommend to persons worried about or with type 2 diabetes to only consume water, unsweetened coffee or tea, or zero calorie artificially sweetened beverages, including soda. Well, it turns out that artificial sweeteners have all sorts of harmful health effects, with different sweeteners (e.g., erythritol) having different effects.

Another recent study found that the consumption of diet drinks and saccharin, a very popular sugar substitute, are associated with an increased risk of type 2 diabetes. In other words, the sweeteners are linked to the very problem people are trying to avoid.

A little confusingly, the researchers did not find a link to type 2 diabetes when looking specifically at overall artificial sweetener, sucralose, and aspartame intake. But they did with saccharin (the oldest artificial sweetener in use) and overall diet drink consumption.

This study questioned people 3 times over 20 years, with a final follow up at 30 years, so perhaps these results are due to different artificial sweeteners used in drinks over time, and even what they themselves purchased. For example, some people buy saccharin to add to coffee and tea at home.

From Medscape: Diet Drinks, Saccharin Tied to Increased Diabetes Risk

Consuming higher amounts of diet drinks and/or saccharin was associated with an elevated risk of developing diabetes, while total artificial sweetener intake, sucralose, and aspartame showed no significant association, according to an analysis of data from the Coronary Artery Risk Development in Young Adults (CARDIA) study. ...continue reading "Diabetes and Artificial Sweeteners"

Published on Leave a comment on New Database of Vaccine Studies, Their Safety, and Their Effectiveness
Credit: Wikipedia

Well, well, well...It's unbelievable, but we've reached a point in this country where vaccines and their effectiveness have to be defended. To combat disinformation and misinformation, doctors have set up a database of vaccines and all the studies that have studied them - whether they work, how well they work, how they were done, and any adverse effects.

Dr Jake Scott, an infectious disease specialist at Stanford University, and his colleagues created a spreadsheet documenting randomized controlled trials (the best kind or research!) conducted for licensed vaccines. There are over 300 such trials listed in the spreadsheet, some of them conducted as early as the 1950s (e.g., the massive polio Salk Vaccine Field Trial). And the vast majority include the safety data (whether the vaccine is safe).

Dr. Scott points out that the evidence (all those studies!) shows that people claiming that vaccines (including childhood vaccines) have not been tested in randomized trials are "unequivocally, demonstrably, measurably false". Vaccines have been studied over and over. And they work!

Information about the spreadsheet and the randomized controlled studies (RCTs) for each vaccine are discussed in an interview with Dr. Jake Scott. Excerpts from CIDRAP (Center for Infectious Disease Research and Policy): Vaccine RCT spreadsheet aims to show the data, dispel myths about vaccines

Since late April, an infectious diseases specialist at Stanford University and his colleagues have been volunteering their time on a project they hope will help educate the public, and combat misinformation, about the safety and efficacy vaccines.

The project, led by Jake Scott, MD, is a spreadsheet of all the randomized controlled trials (RCTs) that have ever been conducted for licensed vaccines. The idea, hatched on the social media site X, was prompted by responses to an old video of current Department of Health and Human Services Secretary Robert F. Kennedy Jr., in which he claims that none of vaccines mandated for US children has ever been tested in preclinical studies against a placebo. In one of the responses, infectious disease physician Brad Spellberg, MD, suggested a crowd-sourced effort to identify and post all of the RCTs in which vaccines have been tested against a placebo. ...continue reading "New Database of Vaccine Studies, Their Safety, and Their Effectiveness"
