Naps can be healthy for adults who need to catch up on sleep or work odd hours, but they can also make it more difficult to sleep at night and be a sign of a sleep disorder. Naps should be short and limited to the early afternoon to prevent them from interfering with nighttime sleep. People who have the urge to nap daily should consider whether they need to improve their nighttime sleep habits.
The COVID-19 vaccine may cause a harmless temporary swelling of lymph nodes that could be mistaken for cancer on a mammogram or other imaging test.
People who are vaccinated against COVID-19 can safely visit with family members who aren’t vaccinated, provided they are not at high risk for severe illness and don’t live with someone who is.
A study published Feb. 16, 2021, in Circulation found that women with blood pressure readings in a normal range may still be at higher risk for cardiovascular events. For example, heart attack risk in women rose at a systolic (the upper number) reading of 110 to 119 millimeters of mercury (mm Hg) and was the same at this level as men with a systolic pressure of 160 mm Hg. But experts say it’s too soon to change blood pressure recommendations for women until more research confirms the results.
Nutritional guidelines continue to advocate eating five daily servings of fruits and vegetables—the so-called five-a-day. New research found that eating more than this amount does not offer extra benefits, and that a ratio of two servings of fruit and three of vegetables might offer the most health benefits.
Using magnetic resonance imaging (MRI) to screen for prostate cancer can identify higher-grade cancers just as well as a standard biopsy, and may help some men with high prostate-specific antigen (PSA) numbers avoid biopsies.
Updated guidelines suggest current and former smokers get an annual lung cancer screening including those who have quit within the past 15 years.
Fiber improves digestion and may help lower a person’s risk for heart disease, diabetes, and cancer. But according to the 2020–2025 Dietary Guidelines for Americans, most people meet only half their daily fiber needs. The main reason is not following a basic healthy diet with foods high in fiber. Making small changes in dietary habits and adopting new fiber-rich foods can help people reach their quota.
Men have a higher risk of having erectile dysfunction (ED) as they age and many can benefit from taking an ED drug. There are currently four choices in the US, and men usually adopt a trial-and-error approach to find the drug and dosage that works for them. The choice also can be dictated by how fast they want the drug to work and how long the effect will last.
People who are not ready to return to the gym can get an all-around workout at home by using only their body weight. Body-weight exercises are often comparable to using weights and machines, and help people return to fitness after an injury or long layoff. They also can help older adults improve everyday movements. A simple workout might include chair squats, step-ups, and push-ups.
