Out Of The Fog

60 minutes of stationary biking is all it takes to lift my mental fog. My quads and calves ache, but my hopelessness fades. The doubts dissipate. The reflexes sharpen.

It’s a feeling very similar to what I always feel, when an aircraft climbs out of a dark cloud cover, and then, all at once, the cabin becomes awash in bright sunlight.

That I feel this way is no accident, but a biochemical reaction. Continuous aerobic exercise triggers the release of endorphin, a chemical found in our brain that acts as the body’s natural painkiller, but which, in greater dozes, energizes us.

This, in combination with a host of other neurochemicals, such as dopamine and serotonin, causes our mood to swing from gloomy to happy.
