Elderberry syrup or tea may help reduce the duration and severity of cold and flu symptoms. But the evidence for these benefits is uncertain, since the studies are small and most did not compare elderberry to standard treatments. Claims that elderberry products can prevent viral infections or boost immunity are unproven. Elderberry supplements appear to be relatively safe; in clinical trials, effects such as nausea, vomiting, or diarrhea were mild and rare.

A type of artificial intelligence that uses a deep machine learning tool to analyze different features from routine mammograms can predict a woman’s risk of heart-related problems, according to a 2025 analysis.

A 2025 survey suggests that many adults don’t have a good understanding of high blood pressure, including not knowing what reading signifies high blood pressure and confusion about symptoms related to the condition.

A 2025 study suggests that more than 99% of people who have a first-time heart attack, stroke, or heart failure have at least one of four risk factors: unhealthy blood pressure, cholesterol, or blood sugar levels, or past or present smoking.

Costochondritis, which is inflammation of the cartilage between the ribs and the breastbone, is one of the most common causes of chest pain and is frequently mistaken for a heart attack.

Pelvic floor dysfunction in women is commonly linked to lower back pain. The odds of developing pelvic floor–related back pain increase for women as they get older due to factors such as diminished estrogen and childbirth-related pelvic floor damage. Lower back pain and pelvic floor dysfunction may also have overlapping signs, including urinary leakage or urgency, a feeling of heaviness in the pelvis or vaginal bulging, constipation or bowel issues, painful sex or urination, and pain with prolonged sitting or standing.

Vaginal probiotics contain live microorganisms and come in oral and suppository forms. Some ads claim these products can prevent or treat infections. But the vagina regulates its own bacterial mix, so vaginal probiotics aren’t necessary.

Women with unusual pelvic or vaginal symptoms should report them to their gynecologist. These symptoms include vaginal odor, itching, or burning; menstrual changes; pelvic pain or discomfort; or new bleeding.

Red light therapy involves using devices that emit red or near-infrared light aimed at the skin. It is believed to reduce inflammation and boost production of collagen. Research suggests it can improve an array of skin problems, including fine lines, dark spots, redness, slow-healing wounds, scars, and acne. Unlike ultraviolet light, red light therapy isn’t associated with greater risks for skin cancer. Scientists are still determining the optimal doses of red light therapy for various skin conditions.

Waking up in the middle of the night happens to women more often after age 55 due to many factors. These include diminished hormones and circadian rhythm changes. Stress, bladder changes, medications, chronic pain, and alcohol and caffeine use can also contribute. People can break the cycle of nighttime wake-ups by practicing good sleep hygiene, addressing medical issues, trying mind-body techniques such as deep breathing or meditation, and limiting caffeine, alcohol, and heavy evening meals.
