Increased heart rate alone can cause anxiety & depression.
A new study found that an increased heart rate in mice triggered anxiety & depression.
This has important implications & consequences for us humans, both as a society and as individuals, esp wrt COVID.
The virus causes damage to the heart/cardiovascular system, like palpitations & forms of tachycardia, & that has surely already caused millions of us to experience anxiety/depression.
