Few people get the recommended two fruits and three vegetables per day. Tips for helping people add more produce into their diets include starting small (making just one minor addition or substitution at a time and sticking with it for several weeks); choosing smarter snacks (like hummus and carrots or apples and peanut butter); sneaking pureed vegetables into pasta and other dishes; making smoothies and soups; and relying on frozen fruits and vegetables.

With influenza virus, a new vaccine must be developed each year to adapt to the virus's changing structure.

Arm tenderness is the most common side effect after vaccination. The injection stretches muscle fibers and triggers an immune response, causing discomfort. People can counter pain by moving the injected arm afterward and applying a cool compress or ice pack.

There are currently nine trials of vaccines for Alzheimer's disease under way. All of them are in people with mild Alzheimer's or with the pre-Alzheimer's condition called mild cognitive impairment. All of the vaccines are designed to encourage the immune system to remove protein deposits from the brain. Most experimental vaccines are given by injection; one being tested at Harvard Medical School uses a nasal spray. It will be several years before we know if any of them will work.

Scientists are trying to create a vaccine that would protect people against all different strains of the influenza (flu) virus. These vaccines are being designed to target parts of the flu virus that don't change regularly and so are consistent across all strains. The perfect vaccine would also prevent symptoms (since current vaccines help prevent hospitalization and death, but not symptoms), and its effects would last for a lifetime. While such a vaccine is still many years away from reality, improved flu vaccines are expected in the meantime.

Increasing potassium levels while lowering sodium may be more effective in lowering high blood pressure than reducing dietary salt alone, particularly for men, according to a 2025 study.

A hydration pack is a backpack designed for almost any kind of outdoor activity that carries large amounts of water and allows easy, hands-free access, which provides a convenient way to stay hydrated without needing to stop for frequent water refills.

Continuing to work in retirement can address many specific health needs of men as they age, such as stronger social connection, better cognitive health, and a greater sense of purpose. Regular work has been linked with higher rates of happiness and a lower risk for multiple health conditions. For men who don't want to re-enter the workforce, options like volunteering and mentoring can offer many of the same health benefits.

Essential tremor is marked by involuntary shaking of one or more body parts, such as the hands, arms, legs, or head. Avoiding caffeine and stress and getting plenty of rest can be helpful. Several medications are available to ease the symptoms.
