Physical activity decreases risk of seven cancers

Is physical activity good for you? During COVID times, it might be prudent to avoid cramped, indoor gyms. But outdoor activity in open spaces is invariably a healthy choice. We know that getting off the couch and out for a walk helps prevent obesity, Type 2 diabetes, and heart attacks. And good news! A recent report from the American Cancer Society says exercise also lowers the risk of seven types of cancers.

Dr. Charles Matthews of the National Cancer Institute in the U.S. pooled data from nine studies about how leisure-time activity affects fifteen types of cancer. His results should act as a huge incentive to get people of all ages moving.

Matthews and his colleagues report that those who engaged in 7.5 to 15 hours a week of physical activity showed significantly lower risk of 7 of the 15 cancers studied. The decrease became greater with more hours of activity.

For instance, moderate intensity activity was associated with 8% lower risk of colon cancer in men. Double the intensity, the benefit was 14%. Risk of breast cancer in women was reduced by 6-10% depending on the amount of exercise. For malignancy of the uterus, the difference was: 10-18%, kidney 11-17%, myeloma 14-19%, liver 18-27%, and non-Hodgkin lymphoma in women 11-18%.

But how does exercise decrease the risk of these malignancies? It’s believed that exercise decreases hormone levels that trigger some types of cancer. We also know that exercise increases the immune response, which helps to fight cancer. Some malignancies are also linked to obesity. Exercise burns up calories and decreases obesity to help lower risk.

Exercise can help to decrease the risk of these malignancies. But never forget that an active lifestyle sets you up for the physical and mental agility you want during your senior years too. Back in the 1960s, a Japanese marketing campaign proposed “10,000 steps a day”, equating to about five miles. Most North Americans walk far less – under 5,000 steps on average.

There are some skeptics, like the writer Mark Twain, who claimed he had been to the funeral of many friends who believed in exercise more than he did.

But it would be prudent for doctors to write on a prescription, “More exercise and use a pedometer.” Why count steps when we all know exercise is good for us? Research consistently shows that pedometers are great psychological motivators. They inspire us to get walking.

Dr. Paul Dudley White, Harvard’s renowned cardiologist, rode his bicycle to work and was a firm believer in stepping-it-up. He taught, “If you want to know how flabby your brain is, feel your leg muscles!” Or as the British historian George Trevelyan remarked, “I have two doctors, my left leg and my right.”

Remember that walking is free, simple and convenient. There’s also no need to try and break the record of the one-minute mile or purchase expensive exercise machines.

Unfortunately, walking five miles daily for a 150-pound person burns up only 500 calories. And it is so easy to consume 500 calories.  Just three of the wrong cookies can undo all that walking.

Exercise and watching calories have always been a tough sell to those who haven’t made it a lifetime passion. Michelle Obama got it right when she planted a vegetable garden at the White House and launched the Let’s Move initiative to help kids engage in physical activity. Starting young is ideal, but it’s never too late to start enjoying a daily walk.  And don’t let the excuse of “no time” deter you.

Heed the Earl of Darby, who advised, “Those who do not find time for exercise will have to find time for illness.”

What is it about those short videos that keep us captivated? Oh! Yes! Our short attention span

Published

As our attention spans decrease, short form videos are becoming more popular. From TikTok, to YouTube Shorts, to Instagram Reels, these “snack sized” videos have positive qualities alongside the bad. Mainly we want to know what makes them so effective, and why are they becoming the go-to choice for both viewers and marketers? In this article, I will be discussing how these videos have received such popularity worldwide.

First, we need to understand what counts as and what is short-form content. According to blog.hubspot.com, “Short-form videos are videos that are less than 60 seconds long.” However, some marketers and content creators agree that short-form videos can be up to 3 minutes. “They are videos that deliver information in a ‘digestible’ format so that viewers can quickly watch and save content if they’re in a hurry or enjoy it.” Now, I’ll talk about the main reasons why these videos are so popular.

First, our attention spans have gone down exponentially. Dr Gloria Mark has written a book called “Attention Span,” and she says her research indicates people’s attention spans have been shrinking over the last 20 years. According to the same article Dr. Mark said that “Back in 2004, we found the average attention span on any screen to be two and a half minutes on average. Throughout the years, it became shorter. So, around 2012, we found it to be 75 seconds. Then in the last five, six years, we found it to average about 47 seconds.” So, it’s notable that our attention spans started out longer but then decreased over time.

Secondly, these videos have become cheaper and easier to make. Unlike long-form videos, which require extensive: planning, editing, and storytelling, short-form videos are simpler. To the point where they can even be shot on a smartphone. For example, DuoLingo, the app that helps learn new languages, went viral on TikTok a long time ago by posting funny, low-budget videos that resonate with millions. Like a video of a DuoLingo plus being: tossed down the stairs, sitting outside on a rainy day, or being soaked by the shower with the title “When you ignore my notifications.”

Lastly, they provide valuable information in a short amount of time, and they are easily accessible. According to a recent Adobe Survey, two in five Americans use TikTok as a search engine, and nearly one in 10 Gen Zeers are more likely to rely on TikTok than Google as a search engine. This isn’t always reliable for real news because anyone can claim to be an expert, and you wouldn’t know if they’re telling the truth. So, even though they give valuable information in a short time, they can also give misinformation or mislead you.

Short-form videos have changed how we watch and learn things. They fit our short attention spans, are easy to make, and share information quickly. Even though they’re fun and helpful, they can also spread false information or leave out important details. Even with these problems, short-form videos are here to stay, so we should use them in proportion, but also enjoy the benefits.

Dr. Edward McInnis on the Importance of Preventive Care in Family Medicine

Published

Preventive care is a cornerstone of modern healthcare, emphasizing the importance of addressing potential health concerns before they escalate into severe conditions. By focusing on proactive measures such as regular screenings, vaccinations, and lifestyle counseling, preventive care offers individuals and communities the opportunity to achieve long-term wellness.

Below, Edward McInnis highlights the transformative potential of prevention in reducing healthcare disparities, alleviating systemic challenges, and ensuring that every individual has the tools and access needed to lead a healthier life.

Understanding Preventive Care in Family Medicine

Preventive care in family medicine focuses on proactive measures to maintain health and prevent illness before it occurs. This approach emphasizes regular health evaluations, screenings, and interventions that identify potential issues early, reducing the likelihood of severe complications. Preventive care fosters long-term well-being by addressing risk factors and promoting healthier lifestyles while minimizing the burden of chronic diseases.

The philosophy behind preventive care aligns with the idea that staying healthy is more effective and less costly than treating illnesses after they arise. Early detection of conditions such as hypertension or high cholesterol allows patients and physicians to manage these issues effectively, preventing them from escalating into more severe health problems. Beyond individual benefits, this care model contributes to healthier communities by reducing the overall demand for healthcare systems.

Benefits of Preventive Care for Individuals and Communities

Preventive care profoundly impacts individuals and the broader community by addressing potential health concerns before they evolve into severe conditions. Early detection through routine screenings can significantly lower the risk of chronic illnesses such as diabetes, heart disease, and certain cancers. This improves individual health outcomes and reduces the emotional and financial toll of managing advanced diseases.

Communities prioritizing preventive care experience a ripple effect of healthier populations and reduced strain on healthcare resources. When more people engage in regular check-ups and adopt healthier habits, the prevalence of preventable conditions drops, creating a collective benefit. Individuals who invest in their health through preventive measures often enjoy longer, more active lives, positively influencing families, workplaces, and society.

The economic advantages of preventive care are undeniable, as early intervention typically costs far less than treating advanced illnesses. Vaccination programs, such as those targeting seasonal flu or childhood diseases, can drastically curb outbreaks, saving lives and reducing medical expenses. These benefits demonstrate how preventive care is a cornerstone of sustainable and effective healthcare systems.

Core Preventive Services in Family Medicine

Family medicine emphasizes various preventive services designed to address health needs across all stages of life. Regular health screenings, such as blood pressure and cholesterol checks, are critical in identifying silent health risks. These assessments provide actionable insights that allow individuals to make timely adjustments to their lifestyles or begin treatment when necessary.

Vaccinations are another cornerstone of preventive care, protecting individuals and communities from infectious diseases. From childhood immunizations to seasonal flu shots, these interventions safeguard personal health and prevent the spread of illnesses within larger populations. Counseling services, including guidance on nutrition, exercise, and stress management, empower patients to take an active role in their long-term well-being.

The Role of Family Physicians in Prevention

Family physicians play a pivotal role in fostering preventive care through their ability to build lasting, trust-based relationships with patients. These relationships enable them to understand not just medical histories but also lifestyle factors, family dynamics, and social determinants of health. This comprehensive knowledge allows physicians to craft personalized preventive strategies that resonate with each patient’s unique circumstances, ensuring a more practical approach to maintaining health.

Beyond individual care, family physicians act as educators, equipping patients with the knowledge to make informed health decisions. Whether discussing the significance of regular screenings or addressing misconceptions about vaccines, their guidance helps patients take ownership of their health.

The continuity of care provided by family physicians also ensures that preventive measures are consistently monitored and adjusted as needed, fostering long-term well-being. Their ability to provide holistic and deeply personalized care sets the foundation for healthier patients and communities.

Challenges in Accessing Preventive Care

Despite its proven benefits, accessing preventive care remains challenging for many individuals and communities. Financial barriers, such as lack of insurance coverage or high out-of-pocket costs, often deter people from seeking preventive services. Additionally, limited awareness about the importance of early detection and health promotion means that some individuals may only prioritize preventive care once a health issue becomes severe.

Geographical disparities also play a significant role in limiting access. Rural and underserved areas frequently face shortages of healthcare providers, making it difficult for residents to receive consistent preventive services. In such regions, innovative approaches like mobile health clinics and telemedicine have emerged as solutions to bridge the gap. Expanding these efforts could help overcome logistical obstacles and ensure that preventive care reaches those most in need.

Cultural factors and mistrust of the healthcare system can further complicate access to preventive services. Addressing these challenges requires a multifaceted approach that includes community engagement, culturally sensitive care, and efforts to build trust between healthcare providers and patients. Strengthening health literacy and facilitating dialogue between healthcare institutions and the communities they serve are also critical steps in overcoming these barriers.

Promoting and Advancing Preventive Care

Advancing preventive care depends on raising awareness and fostering a culture that values proactive health management. Educational campaigns, workplace wellness programs, and school-based health initiatives encourage people to adopt preventive practices. These efforts create an environment where individuals feel empowered to prioritize their well-being, leading to healthier lifestyles and earlier intervention.

The integration of technology is revolutionizing how preventive care is delivered. Wearable devices that track physical activity, heart rate, and sleep patterns provide individuals with real-time data about their health, prompting timely action when irregularities arise. Similarly, data analytics and predictive tools enable healthcare providers to identify at-risk populations and deliver targeted interventions, improving outcomes on a broader scale.
