Chronic Inflammation and Its Impact on Aging While we might wish for our bodies to maintain optimal function throughout our lives, the reality is that as we age, our cells experience a decline in efficiency, often manifesting as minor aches and pains. Some individuals undergo more pronounced changes, such as the onset of heart disease, kidney issues, arthritis and other age-related conditions. Many of these negative aspects of aging can be linked to persistent inflammation, commonly referred to as chronic inflammation. But what is chronic inflammation exactly, and how does it impact the aging process? Today, we aim to answer these questions and provide guidance on reducing inflammation to improve longevity and enhance your quality of life. What Is Chronic Inflammation? Chronic inflammation occurs when you have long-term inflammation that lasts months at a time, possibly even years. With this type of inflammation, there isn’t always an injury that needs to be healed. Rather, your body incorrectly signals to your immune system that there’s something wrong and works to fix it. There are several potential causes of chronic inflammation, including: Persistent infections If you’ve had several viral or bacterial infections, they can trigger an ongoing inflammatory response. Autoimmune disorders Autoimmune conditions, like rheumatoid arthritis or lupus, can cause chronic inflammation by prompting the immune system to mistakenly attack the body’s tissues. Poor sleep Stress can make it more challenging to get adequate sleep

Exploring the Factors That Affect Human Longevity In the last century, there has been a remarkable increase in human life expectancy. In 1900, the average life expectancy was around 32 years, but over the years, it has more than doubled to an average of 76.4 years in the United States. While a person’s genetics usually become more influential in determining their longevity later in life, several other factors play a significant role from birth into adulthood and beyond. In this article, we’re dissecting three factors affecting life expectancy rate, empowering people to make more conscientious efforts toward leading a long and healthy life. What Factors Contribute to a Person’s Longevity? Longevity refers to the length of a person’s life from birth until death. In today’s world, we often use the term more loosely to describe an individual’s potential for a longer life. To better understand longevity, it’s essential to explore three of the main factors that play a role in a person’s ability to live a healthier and longer life. #1 Lifestyle Given the diversity of global cultures and societal norms, it’s unsurprising that people in different regions adopt varying lifestyles, ranging from athletic to sedentary (and many in between)

Cutting-Edge Insulin Delivery Systems For over a century, insulin has been a lifeline for millions, helping to regulate blood sugar and keep diabetes in check. But gone are the days of relying solely on painful daily injections. As we mark 100 years since insulin’s groundbreaking discovery, let’s explore how this game-changing hormone — and the way it’s delivered — has evolved, making diabetes management easier and more advanced than ever. What Is the Role of Insulin in Diabetes? Insulin plays a vital role in regulating blood sugar by helping glucose move from the bloodstream into the body’s cells, where we use it for energy. In people with diabetes, this process is disrupted in one of two key ways: Type 1 diabetes occurs when the immune system mistakenly attacks the pancreas, preventing the body from producing insulin. Type 2 diabetes happens when the body doesn’t use insulin effectively or doesn’t produce enough. Without proper insulin function, glucose builds up in the bloodstream, leading to elevated blood sugar levels and long-term health risks. So, how does insulin actually work? When you eat, your body breaks food down into glucose (a simple sugar)

Why Do Women Live Longer Than Men? Explaining the Life Expectancy Gap Women tend to live longer than men. But why? Is it biology? Lifestyle? The fact that women are more likely to actually make that annual doctor’s appointment? Researchers call this difference the life expectancy gap between men and women, and no single cause explains it. Instead, a mix of biological, behavioral and social factors play a role, from genetics and hormones to everyday habits and healthcare use. So, why do women live longer than men? Let’s look at some of the biggest factors behind the gap. How Big Is the Life Expectancy Gap Between Men and Women? The size of the life expectancy gap has changed over time. In 2010, women had a projected life expectancy that was approximately 4.8 years longer than men. By 2021, that gap had widened to 5.8 years

50 Is the New 40? Understanding Chronological Age vs. Perceived Age If I asked you to tell me your age, would you give me your biological age, or would your brain revert to an age you feel more akin to? (To be fair, we’d probably shave off a few years because we feel younger at heart—and that’s okay). So, is age just a number? Chronologically, we all have a birthday that marks our years on Earth. But what about how old we feel? Those are two very different perspectives. Today we’re exploring the gap between how old you feel and how old you are, the factors that influence those perceptions and the benefits of embracing an age that is a few years younger than the one on your birth certificate. Chronological Age vs. Perceived Age Your chronological age refers to the objective number of years you’ve been alive. In contrast, your perceived age is how young or old you feel physically and mentally. Let’s say you’re 57

The 3 Most Common Age-Related Diseases (and How to Help Prevent Them) Heart disease, osteoporosis and Alzheimer’s disease are among the most common age-related diseases in the United States. While aging increases the risk of developing certain conditions, lifestyle choices and preventive care can play a significant role in lowering that risk. While hitting 10,000 steps a day won’t guarantee perfect heart health, everyday choices — like regular movement, balanced nutrition and quality sleep — can meaningfully influence long-term wellness. Below, we examine three common age-related diseases, why risk increases with age and steps that may help lower your risk. #1 Heart Disease The name alone may not sound too intimidating, but heart disease is the number one cause of death for people in the United States. In fact, it’s so common that one person dies from cardiovascular disease every 33 seconds. So, what is this silent but deadly killer that’s responsible for approximately 20% of the deaths in the United States? What Is Heart Disease? Otherwise known as cardiovascular disease, heart disease comes in many types that can affect people of all ages, and the risk of developing one of them only increases as you age. Some of the most common types include: Coronary Artery Disease (CAD) CAD occurs when the major vessels supplying blood to the heart have difficulty sending it enough blood and oxygen. Cholesterol deposits are usually the main cause of CAD, and the condition generally develops over several decades. Heart Attack When CAD goes undiagnosed, individuals may not know they have it until the blockages cause a heart attack, which happens when the blood flow to the heart becomes severely blocked. How to Lower Your Risk of Heart Disease While there’s no guarantee that you can be completely safe against cardiovascular disease, there are a few preventative measures you can take to lower your risk: Don’t Use Tobacco While this may seem obvious, there are approximately 28 million American adults who currently smoke cigarettes. Cigarette smoke lowers the amount of oxygen in your blood, increasing your blood pressure and heart rate

4 Major Factors That Affect Drug Absorption in the Body Before any medication can relieve pain or treat illness, it must first be absorbed into the bloodstream. But absorption isn’t automatic. In fact, several internal and external factors shape it. In pharmacology, the four major factors that affect drug absorption are: Physiological state of the patient Drug formulation and manufacturing Method of drug administration Chemical properties of the drug itself Below, we break down each factor with examples to show how the body processes medications differently from person to person. The 4 Major Factors That Affect Drug Absorption Drug absorption isn’t a one-size-fits-all process. How quickly (or slowly) a medication enters the bloodstream depends on four main factors: the patient’s physiological state, how the drug is formulated, how it’s administered and the drug’s own chemical and physical properties
