To get an idea where COVID-19 risks are highest, one should consider if an environment has poor airflow, crowds, and low use of face masks. The amount of time spent somewhere and the ability to sanitize the hands should also be considered. The more risk factors that are present, the higher the risk. For example, spending an hour in a crowded, stuffy gym with low face mask use is a bad idea; it’s better to go for a walk and lift dumbbells at home.

People who’ve never experienced wooziness should call 911 if the symptom comes on suddenly or severely, especially if it’s accompanied by other symptoms. However, a person who has experienced wooziness before or been unwell recently should sit down, have a drink of water or juice, and rest for 10 to 15 minutes. If the feeling of wooziness persists, if other symptoms develop, or if it’s hard to get up without feeling faint, one should call 911.

Two-, five-, or 10-minute breaks are all it takes to interrupt the unhealthy physiological processes percolating during long periods of sitting. Ideas for two-minute breaks include hula-hooping or stair climbing. Five-minute breaks allow enough time to walk around the yard or complete household chores. The best way to maximize a 10-minute break is to take a brisk walk outside or follow a 10-minute video designed specifically for a mini workout, such tai chi, yoga, or dance.

We now understand why inflammation increases heart attack risk. As cholesterol invades the wall of the artery, the immune system treats it like it treats other invaders. Immune system cells infiltrate the artery wall, release inflammation-producing chemicals, and send signals for other cells to remove the cholesterol. Then a fibrous cap forms over the plaque. Inflammation inside the plaque can eventually eat away at that fibrous cap. If the cap ruptures, cholesterol and the inflammatory cells and chemicals suddenly spill into the artery, causing a blood clot to form and block blood flow.

High pill burdens have numerous risks, such as medication errors or interactions, loss of interest in sticking to stick to a drug regimen, and a poor quality of life. The trend to eliminate unnecessary medications—a process called deprescribing—should be supervised by a doctor or pharmacist. During such medication transitions, it helps to maintain a pill schedule with a log or chart that notes the medication’s time and dose, and any new symptoms that develop.
