Social robots are assistive devices designed to engage humans and enhance their well-being. Some social robots look like pets and purr when stroked. Other social robots act more like companions; they can notice when people walk into a room, ask how they’re doing, chat about hobbies, play favorite music, or connect to family and friends. They can also remind people to take medications, connect someone to a doctor, or walk someone through physical or mental exercises. Expect to see an increase in social robots starting in 2022.

People who get the COVID-19 vaccine may experience arm pain, rashes, aches, fever, or fatigue. Doctors say it’s worth the risk, since an older adult’s risk of dying from COVID is 3% to 11%.

It may be possible to set up a version of assisted living in one’s current home by hiring various services and adapting the environment to health needs. Services that might be needed include help with basic care (eating, bathing, brushing teeth, and using the bathroom), meals, medication management, housekeeping, transportation, and yard maintenance. To create a safer environment, it’s best to have a single-floor living space with a sleeping area, bathroom, and kitchen or kitchenette; well-lighted rooms and hallways; smooth, even floors; grab bars and a shower bench or chair in the bathroom; and railings anywhere support is needed while walking.

Using artificial intelligence, smart speakers can be programmed to detect and monitor abnormal heart rhythms in people sitting within one to two feet of the speakers.

For people with certain types of valvular atrial fibrillation, drugs known as direct oral anticoagulants (DOACs) may be safer and more effective than warfarin (Coumadin). DOACs include apixaban (Eliquis), dabigatran (Pradaxa), and rivaroxaban (Xarelto).

Eating two servings of fruit and three servings of vegetables daily is linked to a lower risk of dying of cardiovascular disease. The healthiest choices include leafy greens, carrots, berries, and citrus fruits.

Strawberries and blueberries are rich in beneficial plant compounds known as anthocyanins, which give berries their vibrant red, blue, and purple hues. Several studies have linked diets with anthocyanin-rich foods to better heart health.

Obstructive sleep apnea occurs when soft tissue at the back of the throat temporarily blocks the airway during sleep. People with sleep apnea face a heightened risk of high blood pressure, diabetes, heart attack, atrial fibrillation, and stroke. The condition can also affect mood, and some people diagnosed with depression may actually have sleep apnea. Treating apnea with positive airway pressure improves both high blood pressure and depression.

People with heart-related conditions or risks should take simple precautions when travelling by airplane. These include taking steps to ease stress, such as listening to music or reading a good book; bringing medications in their original containers in carry-on luggage; and not worrying too much about blood clots, which are uncommon during air travel even in people with a history of clots.

A diastolic blood pressure reading lower than 60 mm Hg may be linked to an increased risk of heart attack and stroke in people at high cardiovascular risk. Diastolic pressure tends to fall with age. Some people with a low reading have a leaky aortic valve, which interferes with normal blood circulation throughout the heart and causes diastolic pressure to fall. But in people with healthy aortic valves who can be physically active without any symptoms (such as chest pressure, shortness of breath, or lightheadedness), a low diastolic blood pressure should not pose a problem.
