This week's roundup: liver disease, long COVID-19 recovery

By Michael Roizen, M.D. on

You may think of a cat nap as a short snooze, but cats are actually super-sleepers, often slumbering for 12 to 18 hours a day. That's healthy for them, but for humans, sleeping more than an hour while the sun shines can be a sign of developing liver problems, according to a study in BMC Gastroenterology. It found that compared with folks who don't nap, those who slept for 60 minutes or more in the daytime have a 200% increased risk for nonalcoholic fatty liver disease (NAFLD) -- a potentially serious condition that afflicts an estimated 25% of U.S. adults and often goes undiagnosed. So, if you're taking hour-long snoozes during the day, inform your doctor so she/he can check for NAFLD and, if needed, help you manage it.

From long naps to long COVID-19. Ten percent to 30% of folks who've had COVID-19 will develop long COVID-19. They have a 63% increased risk of heart attack and a 52% increased risk of stroke, compared with folks who never caught the virus. The Centers for Disease Control and Prevention says breathing exercises; sitting aerobic and strength-building exercises, initially, and then walking and standing workouts; and the use of medications such as anti-hypertensives can help reduce your risks. Talk to your doc about an individually tailored rehabilitation routine.

Quick tip: A new study finds that mindfulness training helps relieve chronic pain and reduces misuse of opioids for almost half of folks who give it a try. Discover MORE (Mindfulness-Oriented Recovery Enhancement) at Also, try the free "Unwinding by Sharecare" app.
