Link Between Dementia and Faster Heart Rates

New study finds that for people aged 60 or older, an elevated resting heart rate (RHR), may be a risk factor for dementia.

The study, followed 2,147 participants for up to 12 years. Individuals whose RHRs were 80 beats per minute (bpm) or higher had, on average, a 55% higher risk of developing dementia than those with RHRs of 60–69 bpm.

Strong links between the heart and brain health suggest that lifestyle improvements such as exercise, can mitigate the risk of dementia.

Exercise and Cardiovascular Disease

Moderate-to-vigorous physical activity has many benefits, but it may provide the most help to people who already have cardiovascular disease, (CVD).

Cardiovascular disease includes coronary heart disease, heart attack, stroke, heart failure and more.

A recent study including more than 142,000 participants discovered that moderate-to-vigorous physical activity had links to lower all-cause mortality and major adverse cardiovascular events, but was most beneficial to those who already had CVD.

Overall, researchers concluded that every individual can benefit from a physically active lifestyle, no matter what their cardiovascular health status may be.

Fighting COVID-19 with a Lettuce-Based Chewing Gum

Researchers have developed a chewing gum from lettuce that can neutralize SARS-CoV-2 in saliva.

They found that levels of viral RNA in saliva fell to almost undetectable levels after exposure to the chewing gum.

There is now the possibility of this gum reducing transmission and it is hoped that the next step will be clinical trials.
