WHAT IS inflammation, anyway?
BY MARISA COHEN
INFLAMMATION" IS A WORD YOU HEAR EVERYWHERE there are foods and gummies and supplements that claim to fight it, and you could fill an entire wall with books on the subject. But we'll admit that it can still be very hard to figure out what the word actually means.
Inflammation is actually helpful and necessary at least in its acute (or temporary) phase. Without this biological defense system, we wouldn't be able to heal from injuries or fight off infections, says Erica L. Johnson, Ph.D., an associate professor of microbiology, biochemistry, and immunology at Morehouse School of Medicine in Atlanta. "Most of the time this is good, and it helps the body recover," Johnson explains.
Let's say, for example, that you accidentally cut your hand while slicing a bagel. First, your body releases chemicals that act as a kind of red alert; white blood cells respond to this warning and flood the area of your body that needs help (think of a microscopic SWAT team rushing in to fight off the bad guys and protect the injured parts). This can cause pain, swelling, redness, and warmth-all conditions you can see or feel and ones that help your body heal and return to homeostasis, or a state of balance.
When you're fighting off a bacterial infection or an allergen, this protective process happens inside cells, where you can't see it. "An inflammatory response activates your immune system to fight the infection, and that's how you get better," says Sadiya Khan, M.D., Magerstadt Professor of Cardiovascular Epidemiology at the Northwestern University Feinberg School of Medicine in Chicago. After white blood cells neutralize the problem, acute inflammation starts to go away, usually within a few days. Soon enough your wound heals, your fever breaks, and you feel better.

WHY AM I SICK...AGAIN?
It's puzzling: It seems as if everyone's UNDER THE WEATHER MORE FREQUENTLY these days than before the pandemic. But that perception may be A COVID MIND TRICK. Here, top doctors help us piece together the truth.

A Solo Trip at 55 Boosted My Confidence - When I retired, a big, beautiful world opened up to me.
I had never taken a solo vacation before, and when I arrived in St. Maarten two years ago, the fact that I was traveling alone really hit me. I was 55 and divorced, and very apprehensive and self-conscious: With whom would I have dinner? With whom would I sit at the bar? But I put on my big-girl pants the first night and told myself I would grab a bite to eat and then head back to my room and read a book.It didn't turn out that way. I met a fabulous group of other retired women and men, and we talked and danced and drank and laughed all night. We hung out periodically throughout the week, whether at the pool or joining one another for dinner or drinks.
Hormones, ADHD, and the Midlife Balancing Act - Being in perimenopause is all kinds of challenging. Now more women are discovering that their brain fog, lack of impulse control, and constant feeling of distraction may be a clue to something else entirely.
Being in perimenopause is all kinds of challenging. Now more women are discovering that their brain fog, lack of impulse control, and constant feeling of distraction may be a clue to something else entirely. Melanie Hutchinson had always been messy, but in 2020, as she entered her 50s, her home became overrun with clutter. A mountain of laundry overtook her bedroom and piles of paper and junk accumulated everywhere. Before Zoom meetings, she'd hurriedly throw things into laundry baskets and stash them in the basement to avoid an embarrassing background.
Ease Your Allergies - These holistic remedies may provide relief from seasonal symptoms.
For people with seasonal allergies, sniffling and sneezing are just the tip of the drippy, itchy iceberg. And symptoms can range from mildly annoying to truly debilitating.Seasonal allergies, also known as hay fever, are allergic reactions to airborne allergens like pollen and mold spores, says Katie Marks-Cogan, M.D., an allergist at Clear Allergy in Culver City, CA. Normally harmless, certain allergens can prompt an immune response in some people, leading to itchy, watery eyes; sneezing; runny nose; congestion; coughing; and shortness of breath.
Mammogram Confusion, Solved! - It's the rare woman who doesn't vividly remember certain firsts
It's her first period, first bra, first use of a tampon, first kiss, and, yes, first mammogram. But for most women, the age at which they should get that first screening test has changed. Earlier this year, the U.S. Preventive Services Task Force (USPSTF) issued new breast cancer screening guidelines suggesting that women get a mammogram every two years starting at age 40.
5 Myths About Arthritis- Creaky joints are a pain, but some facts” about them are pretty twisted.
Arthritis isn't the only culprit when it comes to achy joints. Infection, injury, bursitis (swelling of the fluid-filled pads that cushion the joints), and tendinitis (inflammation of the tendons that attach muscle to bone) are all reasons they might hurt, says Kirsten Ambrose, M.S., associate director of the Osteoarthritis Action Alliance at the University of North Carolina Thurston Arthritis Research Center. Joint pain is also a symptom of autoimmune diseases like lupus and Hashimoto's disease. So how can you tell if it's osteoarthritis? Get it checked. To diagnose arthritis, doctors typically rely on a patient's history (family background, injuries, and symptoms); a physical exam (looking for bony enlargements or swelling); or imaging like an X-ray or an MRI, Ambrose says. Blood test can show markers of inflammatory arthritis such as rheumatoid arthritis and gout. If it is osteoarthritis, over-the-counter pain medication, physical therapy, and general movement can ease symptoms.
What's Up With...Smelly Gas - You can blame it on the dog, but it happens to everyone.
The average person toots around 14 times a day-it's how your body releases the extra gas that accumulates when you swallow air and digest food, says Shilpa Ravella, M.D., author of A Silent Fire: The Story of Inflammation, Diet, and Disease. If you chew gum or smoke, you'll have even more gas buildup, she adds.
