Dogs And Humans Feel Happy When They're With Each Other, Finds Study

Updated Mar 15, 2025 | 04:00 AM IST

SummaryResearchers enlisted 122 university students and conducted a series of tests to measure their stress levels before and after a short session with a dog. These tests included self-reported stress assessments, blood pressure and pulse readings, and saliva samples for cortisol testing—a key indicator of stress.

We all love our little furry friends. They make us feel happy. But it is no longer just a feeling, but a scientifically proven fact. A new study published in PLOS One highlighted that playing with a dog just for 15 minutes can significantly reduce a person's stress. This could also help stressed students. It was found that when stressed students interact with a friendly dog, they reported less stress, they also had a reduced heart rate and had lower levels of stress hormone cortisol in their saliva.

The experience is the same with the dog too. So, not just humans benefit from the dogs, the furry friends too feel happier! Based on the fecal test, it was found that canine cortisol levels were lower a week after hanging with a human.

The senior investigator Jaruwan Khonmee of the Chiang Mai University Thailand, said, "Even brief interactions with dogs can significantly reduce stress levels among university undergraduate students."

How Was The Study Conducted?

The researchers recruited six friendly dogs between 3 and 6 years of age. They were to interact with college students. This included chihuahuas raised by veterinarians and a Shetland sheepdog raised by a psychologist.

It is important to note that none of these dogs were certified for therapy work.

Researchers enlisted 122 university students and conducted a series of tests to measure their stress levels before and after a short session with a dog. These tests included self-reported stress assessments, blood pressure and pulse readings, and saliva samples for cortisol testing—a key indicator of stress.

What Happened During the Session?

Each student was introduced to a dog, including its name, personality traits, and preferred interactions. They were then given 15 minutes to engage with the dog in any way they preferred—whether it was petting, playing, hugging, giving treats, or simply observing.

After the session, students underwent the same stress tests to measure any changes. Additionally, the dogs themselves provided saliva and fecal samples before and after their interactions with the students to determine if they, too, experienced any physiological changes.

The Results: A Noticeable Drop in Stress

Findings showed a significant reduction in student stress levels. According to the study:

  • Self-reported stress levels dropped by 33.5% after just 15 minutes of interaction with a dog.
  • Physiological improvements were noted, including lower pulse rates and decreased cortisol levels in students, indicating reduced stress.

What About the Dogs?

Interestingly, while the dogs’ salivary cortisol levels remained unchanged on the day of the play session, their fecal cortisol levels were lower a week later. This suggests that although the immediate stress response in dogs was not evident, prolonged exposure to human interaction might have a long-term calming effect on them as well.

Why This Matters

This study reinforces the idea that human-animal interactions can have a measurable impact on stress reduction. The findings highlight two key takeaways:

Dogs can be effective stress relievers for students – even those not trained for therapy purposes.

Animal well-being should also be considered in canine-assisted interventions to ensure that the experience is beneficial for both humans and dogs.

The Bigger Picture: Expanding Canine-Assisted Therapy

While therapy dogs and trained handlers are often used in structured mental health interventions, this research suggests that even non-certified dogs can provide mental health benefits. In settings where professional therapy animals are not available, the presence of friendly, well-behaved dogs may still offer stress relief to individuals facing high-pressure situations.

This Common Heartburn Medicine Causes Bone Loss And Fractures, According To Doctor; Here Are Safer Alternatives

Updated Dec 5, 2025 | 09:38 AM IST

SummaryPantoprazole, widely used in Indian households for acidity and heartburn, may cause serious long term effects when taken regularly, doctors warn. Overuse has been linked to vitamin and mineral deficiencies, impaired digestion and increased risk of fractures. Studies show the drug can reduce bone density, while safer alternatives like H2 blockers may pose fewer risks.

Of the many medicines that we consume on a day to day basis, we are not aware of how gradually they are actually making our health worse. One medicine that is common in many households, especially in India households, as points Dr Obaidur Rahman, Ortho and Sports Surgeon is pantoprazole, popularly sold under the name PAN40, PAN Top or PAN D. These medicines are used to treat and relieve symptoms of heartburn, which is a common symptom of acid reflux and GERD.

"A patient came to me, he was an 80-year-old male. He has a habit of taking this tablet regularly, and because of that he suffered an osteoporotic fracture. This means he fell while walking and fractured," points out Dr Rahman.

He says that many people, old and young, alike, have a habit of taking this pill like a multivitamin. In fact, they have substituted with pro and prebiotics and assume that it helps with digestion. However, he points out, "If you take this regularly, your gastric mucosa stops responding against proper acid production. And there is also an impairment in digestion."

He says that in clinical practice, it has been found that this common household medicine, which is often procured as over-the-counter or OTC medicine, meaning, without prescription, could cause Vitamin B12 deficiency, and magnesium deficiency.

What Does The Science Say About Pantoprazole Use?

As per a 2023 study published in the journal BioMed Research International, pantoprazole cause bone loss, which could be prevented by adding octreotide.

The study analyzed the serum levels of calcium, phosphorus, and ALP before starting the treatment, and at the end of 12 weeks of treatment on pantoprazole, significant decline in calcium levels were noticed, as compared with other groups. The study also found that octreotide significantly prevented the effect of pantoprazole on the serum levels of calcium and ALP.

The study also found that pantoprazole decreased femoral bone density and femoral BMAD. Besides this, another decrease was found in the femoral bone weight and volume as well as the trabecular volume.

Another study from 2021, published in the European Journal of Clinical Pharmacology pointed out that 12 patients had major fractures and showed changes in serum Mg2+ and Ca2+ levels over a period of 1 month as well as the animal study also showed ionic imbalance over 8-week treatment with pantoprazole. Bone density measured for the patient at the end of the 1-month treatment was found to be in the osteopenic category, together with the animal study which showed a decrease in femur bone strength for the animal treated with pantoprazole over a period of 8 weeks.

Are There Any Safer Alternatives To Pantoprazole?

Pantoprazole contain Proton Pump Inhibitor (PPI), and prokinetic, long-term use of PPIs is associated with the risk of bone fracture. However, alternatives like Histamine H2-receptor antagonists or H2 blockers are effective alternative that do not cause bone loss, notes a 2020 study published in journal Bone, titled Comparative analysis of the risk of osteoporotic fractures with proton pump inhibitor use and histamine-2 receptor antagonist therapy in elderly women: A nationwide population-based nested case-control study.

The safer alternatives are:

Famotidine (Pepcid, Calmicid, Fluxid, Mylanta AR) is a potent H2 blocker used to manage acidity and heartburn. Studies show that famotidine is not thought to raise the risk of osteoporosis.

Other options: Ranitidine (Zantac - where available, as it was withdrawn in some markets due to safety concerns) and Nizatidine are other H2 blockers.

Cold, Flu, Or Covid? Simple Ways To Differentiate Between The Three

Updated Dec 5, 2025 | 07:36 AM IST

SummaryScientists warn this flu season may be severe. With COVID variants still circulating, symptoms often overlap, making it hard to distinguish between COVID, flu and common colds. COVID tends to cause dry cough, loss of taste or smell and stomach issues, flu hits suddenly with fever and aches, while colds develop gradually with congestion.

This flu season could be brutal, say the early clues that scientists have gathered. This comes as the world already struggles keeping up with the new variants of COVID, however, the COVID rates in the US appears to be low. Though researchers are expecting the virus to circulate more widely in the coming months as people gather for holidays.

This is also the time for common cold. Dr William Schaffner, an infectious disease specialist at Vanderbilt University Medical Center tells the New York Times that if you feel ill, but your symptoms remain only above the neck, that is, a stuffy nose, a sore throat, then it could just be a common cold.

However, if the symptoms lead to hacking cough, and down the neck, which makes your muscles ache and body tired, that it could be a flu or COVID. Due to the similarities in the symptoms, even infectious disease specialists also struggle to tell the difference.

Symptoms To Take A Note Of

COVID

How it begins: Initially, symptoms of COVID can mimic flu-like symptoms

What are the primary symptoms of COVID?

  • Loss of taste
  • Loss of smell
  • Sore throat: the new variants are also causing razor-sharp pain in the throat
  • Diarrhea or stomach upset

The biggest difference here is the dry and persistent coughing, which when you have a cold will not be dry in nature.

How it impacts? The COVID may vary from mild to severe

Since the pandemic, Covid has blurred the lines between seasonal infections. Current strains can trigger flu-like fatigue, fever, and cough. But the loss of taste or smell and digestive issues are stronger indicators of Covid.

For confirming COVID, test is the only key. There are now at-home tests available online and at drugstores too. An at-home test could detect both, a flu and COVID.

Common Colds

How it begins: The symptoms of common cold starts gradually.

What are the primary symptoms of Common Cold?

  • Stuffy or runny nose
  • Sore throat, but not razor-blade like pain
  • You may feel pressure in the ears

Here, the biggest difference is also in cough, which is often mucus-filled and chesty. Whereas in COVID, the cough is dry.

How it impacts? While it is annoying in the beginning, especially due to the blocked nose and ears, the congestion clears up overtime and usually doesn’t stop daily activities.

Colds typically start with a tickle in the throat or pressure in the ears before progressing to nasal congestion and cough. Most people can carry on with their routines despite the discomfort.

Flu

How it starts? In many cases, the flu may catch you out of the blues, many describe the onset as sudden.

What are the primary symptoms of Flu?

  • Fever
  • Chills
  • Muscle aches
  • Exhaustion

While the cough here is also dry in nature, which may make one get confused with COVID, there is no razor-blade like symptom, which can be used as a marker to differentiate.

How does it impact? Flu often requires bed rest.

Unlike a cold, flu can leave you feeling completely wiped out. Body aches and high fever are distinguishing features, and recovery often takes several days of rest.

Doxycycline: Common Acne Treatment Linked To A Notable Drop In Schizophrenia Risk

Updated Dec 4, 2025 | 04:00 PM IST

SummaryA new study suggests that doxycycline, an antibiotic often used for acne, may lower the future risk of schizophrenia in adolescents receiving mental health care. Learn how the drug works, what the research found, and the possible side effects you should keep in mind.

An antibiotic routinely used for acne has been linked to a lower likelihood of developing schizophrenia. A new investigation from the University of Edinburgh found that adolescents receiving mental health care who were given doxycycline had a reduced chance of being diagnosed with schizophrenia as adults, compared with those who were prescribed other antibiotics.

Although these early findings cannot confirm that doxycycline prevents schizophrenia, the researchers suggest that its influence on immune activity, inflammation, and programmed cell death may help protect the brain from changes associated with the disorder. “Because this research relies on observational records, it cannot prove that doxycycline directly lowers the risk of schizophrenia, so more studies are needed,” the authors explain.

“Even so, the results raise the possibility that doxycycline could play a role in lowering schizophrenia risk among young psychiatric patients and open new avenues for prevention-focused mental health research.”

What Is Schizophrenia?

Schizophrenia is a severe psychiatric disorder that affects about 23 million people worldwide, with most cases identified during late adolescence or early adulthood. The illness can appear suddenly and may bring on psychosis. Typical symptoms include ongoing delusions, hallucinations, disorganized thoughts, restlessness, or withdrawal from others. According to the World Health Organization (WHO), more than two out of three people experiencing psychosis lack access to specialized mental health services.

What Is Doxycycline?

Doxycycline is a broad-acting antibiotic commonly given to teenagers for acne. Some recent research suggests it may also offer certain protective effects for the brain, as it is able to cross the blood-brain barrier. In 2024, Science Alert reported on a Danish study showing that this brain-penetrating antibiotic was associated with a lower likelihood of schizophrenia patients later receiving disability benefits, hinting at how the illness might affect their daily functioning.

To explore this further, child and adolescent psychiatrist Ian Kelleher from the University of Edinburgh led a large international team in reviewing data from more than 56,000 people born in Finland between 1987 and 1997. All had used mental health services in their youth and had been prescribed antibiotics during that time.

The analysis showed that those given doxycycline had a 30 to 35 percent lower chance of developing schizophrenia over the following decade, compared with individuals who had taken other antibiotics. The risk dropped from 2.1 percent in the non-doxycycline group to 1.4 percent in those who used doxycycline.

Doxycycline Linked To A Drop in Schizophrenia Risk

The research team found that taking doxycycline was linked to a 30 to 35 percent reduction in schizophrenia diagnoses over ten years. One theory is that doxycycline may clear an infectious agent that contributes to schizophrenia. Another possibility is that it directly affects inflammation and nerve pathways inside the brain.

Other antibiotics offer hints as well. A 2019 study using stem cells from people with schizophrenia and healthy volunteers showed that minocycline can reduce excessive loss of synapses, a process thought to play a part in schizophrenia. Since both minocycline and doxycycline belong to the tetracycline family, they may share similar properties. Using Finland’s health records, Kelleher’s team noted that nearly half of all psychotic disorders in the population occurred in individuals who had visited adolescent psychiatric services.

The researchers believe this stage of life may offer a valuable period for early intervention, where medications like doxycycline might help reduce the chance of the illness progressing. “Nearly half of the people who develop schizophrenia had earlier contact with child and adolescent mental health services for other issues,” Kelleher says.

“At the moment, we do not have any proven ways to lower the risk of schizophrenia in these young people, which makes these findings encouraging.”

Does Doxycycline Have Side Effects?

Doxycycline is available in two forms, doxycycline monohydrate and doxycycline hyclate, though both tend to cause similar reactions. This list does not include every possible side effect, so consult your medical provider if you are unsure about anything you notice while taking the medication.

Mild doxycycline side effects include:

  • Nausea or vomiting
  • Diarrhea
  • Sensitivity to sunlight
  • Sore throat or difficulty swallowing
  • Vaginal yeast infection
  • Itchy skin and rash (urticaria)

Rare but serious doxycycline side effects include:

  • Ulcers in the esophagus
  • Severe skin reactions
  • Liver problems
  • Tooth discoloration in children
  • Clostridioides difficile (C. diff) diarrhea
  • Intracranial hypertension (increased pressure around the brain)
  • Low blood cell counts

Always speak with your healthcare professional before starting or stopping any medication.
