Healthy European cuisines from beyond the Mediterranean

In addition to the Mediterranean diet, other European eating patterns—namely, the Nordic diet and the Atlantic diet—feature heart-healthy fare. All three diets feature seafood, vegetables, fruits, whole grains, legumes, and nuts, with an emphasis on seasonal and local foods. Such foods also support environmental health and sustainability. People in the United States can follow this trend by shopping at a farmer’s market or joining a community-supported agriculture program.

When the heart suddenly starts racing

Paroxysmal supraventricular tachycardia is caused by an electrical glitch in the heart’s upper chamber that causes the heart rate to suddenly soar for no apparent reason—sometimes as high as 200 beats per minute. The condition, which people describe as palpitations or a fluttering sensation in the chest, is usually not dangerous. But long-lasting bouts can lead to lightheadedness, breathlessness, and fainting.

Interval training: A shorter, more enjoyable workout?

High-intensity interval training (HIIT) is a time-efficient way for people to improve their fitness and cardiovascular health. Even short bursts of high-intensity activity may trigger the release of mood-boosting brain chemicals. Traditionally, HIIT features 30 to 90 seconds of high-intensity effort followed by an equal or longer period of lower-intensity activity or rest. HIIT variations include fartlek (Swedish for “speed play”), which uses environmental cues to set intervals, and Tabata, which features 20-second intervals of intensity followed by 10-second recovery intervals.

Sleeping apart: Good for your sex life?

A survey found that one-third of couples reported occasionally or regularly sleeping in separate rooms to accommodate a bed partner. The main motivation behind separate sleeping is to ensure both people get a good night’s rest, as sleep can get disrupted by a partner’s snoring, teeth grinding, thrashing, sleep schedule, and different sleeping environments. Couples should work together to ensure sleeping apart does not interfere with intimacy, such as scheduling snuggle time, taking naps together, and planning times for sexual activity.

Drugs for Alzheimer’s disease

There is no cure for Alzheimer’s, but medication can help manage the disease. Currently, the main FDA-approved drugs used to treat Alzheimer’s are symptomatic drugs, which ease symptoms but don’t address the cause of the disease. A new medication has been shown to slow the disease’s progression and reverse some of its effects on memory among people with mild Alzheimer’s.
