Having your sleep interrupted by the need to urinate (the medical term is nocturia) is a common cause of sleep loss, especially among older adults. Nearly two-thirds of adults ages 55 to 84 deal with this problem at least a few nights per week.

People with mild cases may wake two times a night; in severe cases, it may be as many as five or six times. The result can be significant sleep loss and daytime fatigue.

Fear can be a helpful signal; it can bring your attention to problems—such as a balance disorder, reduced vision, or muscle weakness—that keep you from moving confidently. But fear can also undermine you. Persistent worrying about a fall, if it's unwarranted, may cause you to limit your range of motion unnecessarily and avoid activities that you're capable of. It's estimated that one-third to one-half of older adults are concerned enough about potential falls that they have begun to restrict or avoid activities that would be beneficial for their health.

How can you build your confidence? If you don't trust yourself when walking, it's important to talk with your doctor to understand the cause of the fear. Is it a sign of a health problem — perhaps a vision problem or arthritis pain — that you need to address? Do you need a hip replacement or a new pair of glasses? Or are you worried about your sense of balance?

Make the most of your skin barrier to ward off certain types of disease. Hint: It pays to moisturize.

Picture it: You're the body's military commander, and you're reviewing your protective forces. Immune system? Check. Stomach acid? Check. Beneficial gut bacteria? Check.

Don't forget to include your skin: it's one of the most important bastions in the fight against disease, keeping harmful organisms and substances from getting inside the body.

Are artificial sweeteners benign or a threat to your long-term health? A recent study adds a new element to the debate.

Artificial sweeteners seem to offer a tantalizing free pass to dessert. These low- or no-calorie additives taste like sugar, but your body can't absorb them the same way it does natural sugars. You get the taste without the calories, which should mean that you can eat them guilt-free. Right?

Over the years, experts have increasingly questioned whether artificial sweeteners are too good to be true. Are they really your ticket to a ­low-calorie treat — or will you wind up getting your just desserts for trying to outsmart Mother Nature?
