21 Bizarre Side Effects of Becoming a Running Junkie
7. Losing A Few Inches

Though running can help shed some pounds, it can also shed some height from the body, but there is no reason to worry because it is only temporary. The feeling of being shorter and physical change is a result of losing intervertebral disc fluid from the spine whiling running. The body will restore the fluid soon after the run and return the body to its original height.
8. Heightened Hearing

Some runners have reported how their hearing seems to become sharper and clearer during a long run. They are not just making this up either; hearing can improve while running because of the increased blood circulation that is created by running long distances. The increased circulation also brings nutrients up to the ears.
