Lung cancer kills about 130,000 Americans yearly, but only a tiny percentage of people eligible for low-dose CT lung cancer screening receive it. People qualify for lung cancer screening if they are 50 to 80 years old, have a substantial smoking history as measured in lifetime packs smoked, and currently smoke or quit within the past 15 years. Tens of thousands of lives might be saved each year if everyone who qualified underwent lung cancer screening, which can detect tumors when they are still small enough to be cured with surgery or radiation.

Hair loss is common in the months after recovering from COVID-19 infection. It can also happen in people with long COVID or because of mental stress from the pandemic. COVID-related hair loss is a form of telogen effluvium, a condition in which normal hair shedding ramps up after intense physical or mental trauma. Hair regrowth usually takes six to 12 months. People can speed and support hair regrowth by avoiding harsh hair habits, checking nutrient levels, and applying minoxidil (Rogaine) to the scalp.

Lactose intolerance can develop at any age, prompting gas, bloating, nausea, or diarrhea after people eat or drink dairy products. Secondary lactose intolerance can happen after the small intestine is jolted by surgery, illness, or injury.

The COVID-19 pandemic shut down many gyms, spawning new online fitness class options that included Spin, Pilates, dance, and yoga. Maintaining an exercise routine during the pandemic offered multiple physical and mental health benefits by boosting mood-related brain chemicals and enhancing sleep. People exercising virtually could stay fit and maintain contact with others without risk of COVID infection. Even beyond pandemic-related concerns, virtual workouts can offer convenience, variety, privacy, and a sense of shared experience.

Certain medications are safer and more effective than others for treating spine pain in older adults, according to a recent study. Among these are the over-the-counter drugs acetaminophen (Tylenol) and ibuprofen (Advil) and some nerve pain drugs, muscle relaxants, and antidepressants.

The American Heart Association recently revised its checklist for achieving optimal heart health. Adequate sleep was added, and updates were made to previous recommendations for diet, cholesterol and blood sugar measurements, and nicotine exposure.

Influenza vaccines that contain higher doses and extra ingredients (adjuvants) to boost their effectiveness can provide better protection than the standard flu vaccine for adults ages 65 and older, according to the CDC, and are recommended for the upcoming flu season.

Left-handers make up only 10% of the population. Despite some common beliefs, science has yet to show that left-handers have any specific advantages or disadvantages over right-handed people in terms of physical abilities, cognitive health, or longevity.

Body-weight exercises are ideal substitutes for regular workouts when people are short on time or looking to shake up their usual routine. These types of exercises are not only versatile—as they can be done anytime, anywhere, without any equipment— but they also help improve everyday movements by activating the smaller stabilizing muscles that sometimes get missed when a person uses gym machines or dumbbells.
