The answer to your question is Dopamine and Serotonin. Dopamine is a neurotransmitter
that affects our focus, drive, attention, memory and clear thinking. Elevation
of dopamine levels leads to improvement in our mood, alertness, and libido.
Serotonin, on the other hand, helps regulate a wide range of psychological and
biological functions. It regulates psychological functions such as mood,
anxiety, arousal, aggression, impulse control and thinking abilities.
