Scientists from the United Kingdom have targeted a brain chemical that may help explain the connection between exercise and increased mood. The researchers found that aerobic activity seems to boost the body’s levels of phenylethylamine, a chemical that is linked to energy, mood and attention.

After refraining from exercise for one day, the men exercised again and the urine was measured. Again, a dramatic increase in phenylethylamine levels was found.
