The blood supply in the US is critically low, but FDA guidelines prohibit men who have sex with men from donating blood if they have been sexually active in the previous three months. All donated blood is tested for a number of transmissible infections, and medical organizations are calling for this policy to be changed.

Many medications are effective for managing (but not preventing) chronic inflammation. The most common medications include nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, immunosuppressants, and biologics. These drugs can have dangerous side effects, so a physician must oversee their use. Other important ways to manage chronic inflammation include treating underlying causes of inflammation and living a healthy lifestyle, such as cutting out processed foods and taking a 10-minute walk each day. A healthy lifestyle may also help prevent chronic inflammation from developing in the first place.

Shingles is a painful condition caused by the varicella-zoster virus. People typically encounter this virus, which causes chickenpox, in childhood. The virus stays dormant in the body, sometimes for decades, and may re-emerge as shingles. The best way to prevent shingles is by getting vaccinated. People should get the vaccine even if they've had shingles in the past, because it is possible to get shingles more than once. Maintaining healthy habits, such as eating right, getting enough sleep, and managing stress, may also help to prevent shingles by keeping the immune system working well.

It's common to have a cough for weeks after an upper respiratory infection. When a cough lasts six weeks or longer, doctors may order a chest x-ray to check for an underlying lung problem. Chronic coughing also can result from medications, postnasal drip, acid reflux, or asthma.

Air pollution is an often overlooked yet important contributor to cardiovascular disease. Tiny particles known as PM_2.5 travel deep into the lungs, where they irritate receptors and trigger nerves involved in the autonomic nervous system. This irritation also contributes to inflammation, which accelerates atherosclerosis. Climate change can worsen the damaging effects of air pollution in several ways, such as by promoting wildfires and dust storms, which creates more PM_2.5. To reduce pollution's harmful effects, people can check air quality information and use portable indoor air cleaners when pollution levels are elevated.

Chronic stress is bad for health. It can trigger physical problems, including chronic inflammation—the persistent activation of the immune system, which sharply raises the risks for many diseases such as dementia, heart disease, or stroke. Ways to reduce stress include living a healthy lifestyle, doing relaxation exercises, stretching, being mindful, taking a brisk walk, reducing loud noise, using laughter, playing soothing music, countering negative thoughts, reaching out for help from a loved one, and using positive self-talk.

Probiotics can be helpful in some cases, but it's unclear whether they are safe for all older adults.

Research shows that a diet rich in anti-inflammatory foods, such as fruits and vegetables, healthy oils, and whole grains, may help prevent some joint problems, such as gout or even osteoarthritis. The benefit is less pronounced if a person has joint problems already. Diet cannot reverse joint problems completely, but it may help with disease management in combination with other treatments.
