Feeling young may be one way to keep getting older. In a new study, a pair of researchers from University College London found that older people who felt three or more years younger than their actual age were more likely to be alive eight years later than those who felt more than one year older than their actual age. Does a youthful feeling keep people alive? Possibly: feeling younger may lead to better health habits, like exercising and eating healthfully. Feeling younger may also inspire a sense of resilience that keeps people young.
Getting up at night to use the bathroom is often thought of as a problem mainly for older men. Not so—two in three women over age 40 wake up at least once each night because of a full bladder. And nearly half of them make two or more nighttime trips to the bathroom. Factors that increased the likelihood that a woman woke at night to urinate included older age, having had a hysterectomy, having hot flashes, and using vaginal estrogen. Many of the women had no other urinary problems, such as an overactive bladder or leaking urine when coughing, and many weren’t especially bothered by having to get up at night to urinate. Getting up once or more each night to urinate may not be “bothersome,” but it can still cause problems. It can interfere with sleep. It can also lead to falls and injury.
One way to avoid adding extra pounds over the holiday season is by relying on the glycemic index to choose your foods and snacks. The glycemic index is a measure of how fast carbohydrates are turned into sugar. The higher a food’s glycemic index, the faster your body turns that food into sugar, and the sooner the “hunger bell” rings again. This can set into motion the cycle of holiday overeating. One way to go low glycemic: Choose foods your grandmother used to eat—ones that resemble things in nature, and don’t come with long lists of ingredients.
If your fingers turn ghostly white and numb when they get cold, you may have Raynaud’s syndrome (or disease or phenomenon). This common condition Raynaud’s is an exaggeration of the body’s normal response to cold. It usually affects fingers and toes, but may also affect the nose, lips, ears, and nipples. Named after the French physician who first described it in 1862, Raynaud’s is a problem in the body’s arteries. They spasm and collapse in response to cold or stress. Without a steady supply of warm blood circulating through them, the affected body part becomes pale. When the spasm ends and the arteries reopen, allowing blood to flow again, the finger, toe, or other body part turns pink or red. It may throb or tingle. Prevention—staying warm—is the best medicine. It’s possible to cut an attack short by running your hands under warm water, putting them in your arm pits, or waving your arms in circles to get the blood flowing. Other options include thermal feedback and relaxation techniques. More experimental options include Botox injections and sildenafil (Viagra).
