singularity75Why does caffeine keep me awake?
Caffeine interrupts our daily sleeping patterns by altering the chemical reactions in our brain.
An addictive drug that 90% of Americans consume every day, caffeine prevents us from getting our ZZZZs by increasing nerve activity in our bodies-keeping us alert and hyperactive.
After drinking a hot cup of caffeinated coffee, the caffeine causes three different chemical reactions that boost our energy levels:
It energizes us by pumping the hormone adrenaline into our systems.
It increases dopamine levels within our bodies. Dopamine is a neurotransmitter that stimulates our "pleasure areas" in our brain making us feel good.
It blocks the connection of adenosine to nerve cells. Adenosine is the chemical that attaches to receptors in the brain and causes drowsiness by slowing down nerve cells activity.
