21 Bizarre Side Effects of Becoming a Running Junkie
5. Strange Itch

While running, one may have noticed an itchy sensation in the muscles. Dry skin may be the reason behind the itching, but it could also be the result of capillaries and arteries quickly expanding and stimulating nearby nerves. Thankfully it does not take long for the sensation to go away. To reduce irritation, make sure the skin is well-moisturized before heading out for a run.
6. Fuzzy Head

It is normal for the head to feel a bit fuzzy after a long run. During the run, the body gradually uses up all the glycogen in the body. Glycogen is a vital substance that helps the brain function properly. To recover from the brain fog, drink a recovery beverage such as orange juice and pair it with a snack to help rebalance blood sugar.
