This is something we’ve been teaching in Functional Neurology for 15 to 20 years.
It’s always surprising to discover that even neuroscientists need a ‘jolt’ to realise it though:
Her prescription is 30 minutes of exercise that gets you out of breath 4 x week.
One aspect missing from the research though is the effects of poor spinal function on brain health. If the spine is not moving properly, then you can not get the full benefits of exercise.
So make sure your spine is fully mobile by getting it checked (you’ll also help prevent injuries).
