Exercise: Researches don't know precisely how much exercise is needed for good brain health, but one thing is very clear- you only reap benefits if you exercise on a regular basis.
You can't exercise for a week or two and consider it done. The available research suggests that the exercise does not have to be extreme, but should be moderately vigorous- and that the more time you spend exercising, the better.
Here are a few hints of building more activity into your daily routines:
When possible, walk instead of driving
Set aside time each day for your exercise program
Use the stairs instead of the elevator
Plant and tend a garden
Refrain from sitting long periods of time
Take a long walk and enjoy nature
You need your sleep
