When it comes to your “health numbers,” your two blood pressure values are important to know—and keep under control. New guidelines for managing high blood pressure in adults, released this morning in a report in JAMA, aim to help doctors know when to start treating high blood pressure and how best to do it. The new guidelines recommend different treatment targets for individuals age 60 and older and those under age 60. They also offer doctors advice on the best medications to start with to control high blood pressure. Although the new guidelines address an area of controversy—how low should blood pressure go—they don’t change the basics: Know your blood pressure. Consider high blood pressure to be a reading of 140/90 or greater. Lifestyle changes are important. And tailor treatment to your needs.
Could tea be a health beverage? Eleven new studies in the American Journal of Clinical Nutrition highlight the many ways that tea may improve health: Tea drinking appears to lower the risk for heart disease and stroke, may strengthen bones, and appears to improve mood, concentration, and performance. Natural compounds called polyphenols in tea might protect against several cancers, including those of the prostate, GI tract, lungs, breast, and skin, and may also increase metabolism and promote weight loss. Those possible benefits apply to tea, not tea extracts condensed into pills. If you’re a tea drinker, enjoy your favorite brew with the added satisfaction that it may be good for your health. If you aren’t, there’s no reason to start.
A longer lifespan can be a double-edged sword. You live for more years, but the later years may not necessarily be what you had in mind. We’ve known for some time that about 25% of older Americans can’t perform some activities of daily living without help. But we don’t know much about the other 75%. A new study suggests that two-thirds of Americans over age 65 need help doing everyday activities such as eating, bathing, and getting in and out of bed or a chair. Things you can do to help ward off becoming frail or disabled include staying active, managing weight and eating a healthy diet, preventing falls, making connections with others, and seeing your doctor(s) regularly.
Sleep apnea—pauses in breathing while sleeping followed by snoring-like gasps for breath—can cause daytime drowsiness and mental fatigue. It can also boost blood pressure and the risk for developing heart disease. A new study suggests that treating sleep apnea by using a breathing machine during sleep can make a difference for people with hard-to-treat high blood pressure. Although blood pressure medications offer a bigger bang for the buck to reduce blood pressure, treating sleep apnea can help, and offers other benefits as well. Getting used to using a breathing machine, which delivers continuous positive airway pressure (CPAP), may take some work. One key is to find a mask that works, which may be a trial-and-error process.
If you have trouble finding the motivation to break away from the television and exercise, try couchersizing—staying on or near your couch and exercising during commercial breaks. Why bother? A growing body of evidence links the amount of time spent sitting to illness and even death. And just minimizing long periods of inactivity, like exercising during commercial breaks, can help reduce the risk of injury and may even help you live longer. You can work many different muscle groups while seated upright on a couch. Want to get your heart rate up, work the oblique muscles on the sides of the abdomen. To whittle your waist, try twisting your torso from side to side for the length of a commercial break. You can even exercise while lying on the couch.
