Most Americans only eat about one-half of the daily requirement for fiber. Changing food sources and eating habits are often at fault.

Science suggests that the placebo effect, in which a person derives a physical benefit from a fake treatment, can have real health benefits for managing pain. It may even work if people are aware that the treatment is a sham. The ritual of receiving treatment is essential for the placebo effect to work, and it's possible for people to tap into its benefits by adopting healthy habits that require rituals and procedures like healthy eating, exercise, and meditation.

Every second, someone age 65 or older suffers a fall, making it the No. 1 cause of injury-related death among this age group. The best way for older adults to protect themselves is to address the three main physical conditions that contribute to falls: weak stabilizer muscles, poor core strength, and balance issues. They can do this by improving their side-to-side motion through specific exercises and playing racquet sports, doing abdominal exercises, and practicing tai chi.

When navigating the health care system becomes challenging, a number of professionals can help. Some, such as home care aides or certified nursing assistants, can assist with errands such as getting to the doctor and picking up medications. Others, such as Aging Life Care Professionals or patient advocates, can develop and run a person's overall care plan, negotiate with insurance companies, arrange to pay medical bills, research treatment options, hire and manage home care helpers, and more.

Many medications can affect sleep. These include prescription drugs as well as over-the-counter remedies. For example, decongestants, certain antidepressants, or beta blockers can make it hard to fall or stay asleep, and nicotine replacement medications can cause a person to have nightmares. Strategies to avoid drug-related sleep problems include taking the medication during the day, taking a lower dose, practicing good sleep hygiene (such as going to bed and waking up at the same time each day), or switching to a new medication.
