To further our theme from earlier posts on well-being and schooling, I (Cathy) looked up the right time to exercise to help your brain.  These tips were suggested:

• In general, anything that is good for your heart is great for your brain.
• Aerobic exercise is great for body and brain: not only does it improve brain      function, but it also acts as a “first aid kit” on damaged brain      cells.
• Exercising in the morning before going to work not only spikes brain activity and prepares you for mental stresses for the rest of the day, but also      produces increased retention of new information, and better reaction to      complex situations.
• When looking to change up your work out, look for an activity that incorporates coordination along with cardiovascular exercise, such as a dance class.

These all made sense, but none of them identified when or why I like to exercise for my brain.  When my mind is somewhat numb after a few hours of academic writing, I need to push the refresh button.  I achieve this walking by the lake.  I am sure it is good for my lungs, my joints and my heart, but I really head to the water to recharge my neuro cells and feast my eyes.  The scenery renews me as much or more than the exercise.  Maybe just seeing what I saw yesterday will refresh your neurons…
