Boosting your child's immune system
As children go through another school year under the cloud of the COVID-19 pandemic, parents are asking what they can do to keep their children healthy. While no magic solutions can ward off every illness, parents can take steps to help children — and everyone in their household — protect their health by keeping their immune systems robust.
COVID-19 vaccination may lower the risk for long COVID
People who received a COVID vaccine during the first two years of the pandemic had a lower risk of developing long COVID, according to a 2024 study.
The wide-ranging effects of psoriasis
Psoriasis causes skin cells to multiply far faster than normal, leading to scaly, itchy, painful skin plaques. While treatments have vastly expanded, stigma surrounding psoriasis persists. Skin lesions can affect what people wear, what they do, and how they relate to others. To better cope, people with psoriasis can get family members involved in care and treatment decisions, see a dermatologist for more advanced therapies, revisit which treatments may work for them, and connect with others with the disease.
What is sepsis?
Sepsis is the immune system's overwhelming response to infection. It can lead to a dramatic drop in blood pressure that damages vital organs and causes death. Sepsis risk factors include older age, recent surgery, chronic illness, artificial joints, or a suppressed immune system.
Fighting inflammation with food
A healthy diet is believed to play a role in warding off chronic inflammation that can lead to chronic diseases such as diabetes, cardiovascular disease, cancer, and cognitive decline. Six types of foods that may help fight chronic inflammation are berries, fatty fish, leafy greens, nuts, seeds, and tomatoes. These foods are all found in a Mediterranean-style diet, which consists of fruits, vegetables, legumes, whole grains, nuts, seeds, lean proteins, and small amounts of dairy foods and olive oil.
Cellulitis: How long does it take to heal on legs?
Cellulitis, a skin infection that often occurs on the lower leg, develops when bacteria enter the body through a cut, bite, or other wound. A new study shows key aspects of healing typically occur within 10 days of treatment, but symptoms can linger for some time after that.
Wondering what your lymph nodes have done for you lately?
The human body has hundreds of lymph nodes, one part of the immune system that helps defend the body against health threats. They aren't usually noticeable, but they are always working to deal with potential health problems.
Got immunity? Thank your thymus
The thymus gland is very important in the development of the immune system during fetal growth, infancy, and early childhood. As we grow into adulthood the thymus shrinks, but growing evidence suggests the gland may play a role in adult health for much longer than previously thought.
