People with celiac disease must avoid all foods that contain the protein gluten, found in wheat, barley, rye, and other grains. Those with nonceliac gluten sensitivity can also benefit from a gluten-free diet.
Shingles is a painful condition caused by the varicella-zoster virus. People typically encounter this virus, which causes chickenpox, in childhood. The virus stays dormant in the body, sometimes for decades, and may re-emerge as shingles. The best way to prevent shingles is by getting vaccinated. People should get the vaccine even if they’ve had shingles in the past, because it is possible to get shingles more than once. Maintaining healthy habits, such as eating right, getting enough sleep, and managing stress, may also help to prevent shingles by keeping the immune system working well.
Sleep supplements, such as cannabidiol (CBD), melatonin, valerian, and chamomile promise a better night’s sleep. But there is little evidence showing that they are effective. In addition, supplements aren’t regulated, so it’s not always clear if a formula contains what’s listed on the label. Experts say that behavioral strategies are a better way to improve sleep. These include getting more exercise, going to bed and waking up at the same time each day, and sleeping in a cool, dark room.
A 2021 study verified that intermittent fasting may be an effective weight-loss strategy. It also seemed to improve some measures of risk for cardiovascular disease, such as lowering blood pressure, cholesterol, and blood sugar.
A 2021 study found that people who underwent cataract surgery (a procedure replace the lens of the eye) appeared to have a lower risk of developing dementia than those who had cataracts but did not undergo surgery.
A 2022 study examined the brains of older adults after they died, and found that those who had stayed the most active late in life had higher amounts of synaptic proteins. These proteins improve the connections between the brain’s nerve cells.
Varicose veins are a common, treatable condition. They occur when valves inside the veins weaken and allow blood to flow back toward the feet, instead of up to the heart. People may be more prone to develop them if there are others in their family who have them. Lifestyle changes, such as increasing exercise and wearing compression stockings, can help prevent them. While varicose veins used to be treated surgically, today they are commonly addressed using less invasive office procedures. Treating veins early can help to prevent complications, such as skin pigmentation changes, leg swelling, and skin ulcers.
A study found that women who were vaccinated against COVID-19 experienced a slight, temporary increase in the number of days between menstrual periods after getting the shot. Experts say the variation is not harmful and does not affect fertility.
A sudden urge to use the bathroom when arriving home, sometimes called latchkey incontinence, occurs when the brain associates coming home with the need to urinate, whether the bladder is full or not. Bladder training may help address this pattern.
Past research shows that exercise may help to prevent dementia. A new study found that this may be true even for people who only do light daily activity, such as errands or housework. People who got only a little exercise still had a lower risk of dementia than those who were inactive. The risk reduction, however, was not as large as that seen in people who exercised more. Adding small daily bouts of activity may still make a difference when it comes to brain health.
