The daily onslaught of news during the past year has left many people in a steady state of fatigue, resignation, and grief. The symptoms of collective trauma are widespread and familiar, but one merits special attention: numbness, which is one possible response to an overwhelming situation.

Diet, exercise, and sleep work together, and all three can have an effect on our daily well-being and longevity. Sleep impacts our eating patterns, and our eating patterns affect our sleep: lack of quality sleep may make people eat more, and make less healthy food choices, but certain foods contain substances that may enhance sleep.

Benzodiazepines and drugs with strong anticholinergic effects have been linked to Alzheimer's disease in people who take them. There are alternatives to both types.

Crying is a natural response to a range of emotions, but is it good for your health? Crying is an important safety valve: it acts as a safety valve for our emotions, and emotional tears flush stress hormones and other toxins out of our systems.

Too much time together makes for tense moments. Cutting each other some slack and setting ground rules will help.

There's such a thing as too much togetherness at home, no matter if you're with a romantic partner, an adult child, a grandchild, or a friend. "Because of the pandemic, we're frozen in place with people, but we aren't meant to be in the same space all day long," says Dr. Robert Waldinger, a psychiatrist with Harvard-affiliated Massachusetts General Hospital.

Keeping the peace starts with understanding why you may be getting on each other's nerves. Then you can try following a few rules to get along better.

Flavanols give fruits and vegetables their bright colors. They are also found in tea and cocoa. Observational studies have shown that eating foods rich in flavanols is linked with less cognitive decline as people age. New research suggests a possible reason why: flavanols appear to improve blood flow to the brain.

Researchers gave cocoa flavanols to 18 healthy adults in two separate trials. In one, the people consumed a cocoa drink with about 681 milligrams (mg) of flavanols. In the other, they had a cocoa drink with about 4 mg of flavanols. About two hours after having the cocoa drink, participants briefly inhaled air with high concentrations of carbon dioxide to raise their blood level above normal. (The brain's normal response to high blood carbon dioxide levels is to increase both blood flow to the brain and its uptake of oxygen.) The researchers then measured the speed of brain oxygenation and administered a set of mental tasks to assess cognitive performance. People had a faster brain oxygenation response after consuming high amounts of flavanols compared with lower amounts. They also scored higher on the cognitive tests and correctly solved problems 11% quicker.

Over the past year, so many of us have experienced various forms of trauma, and reported mental health symptoms have increased dramatically. But at the same time, people have shown resilience and found small moments of solace, relief, and even joy in life’s simple pleasures — and these moments help.

Empathy helps people get along with others, but the ability to understand another person’s experience comes more easily to some people than to others. However, the capacity for empathy can be honed and improved like any other skill.

So how do you keep your brain healthy, stay cognitively fit, and build your cognitive reserve? It's easier for some people than for others. And though genetics set the stage for your brain health, you can do something to improve your brain health and cognitive fitness.

First it is important to remember that you need a healthy body to have a healthy brain. Therefore, ensuring your brain health depends upon regularly seeing your doctor, following her or his recommendations, and managing any health conditions you have.
