If I were to drink an espresso at 5:30pm and then go for a 2h run, would the caffeine still affect my sleep at say 9:30pm? I understand that the half life of caffeine is around 4-6hours, so my question is, would this reduce after burning extra energy?
In: Biology
Caffine blocks receptors for hormones which regulate sleep. Those hormones are produced anyway, even if caffeine is blocking them being received.
Exercising won’t significantly affect the rate at which caffeine is broken down in your body, but may stimulate additional production of hormones.
So it won’t make you sleepy any sooner, but may well make you more sleepy when the caffeine begins to wear off.
