what is the afternoon crash?


What causes a person’s energy to “crash” and become extremely tired in the mid afternoon? Is there a way to prevent it besides caffeine?

In: Biology

Your energy level is a up and down throughout the day. It’s natural and even caffeine can’t prevent in long term.

Its a result of caffeine. the biological half-life of caffeine is 3-7 hours. So if you have caffeine in the morning, by afternoon at least half of it and maybe all of it has been removed from your system.

If you don’t drink caffeine, you will not experience this crash. If you do, then its caused by the caffeine. and drinking more caffeine will give you a bit more time before you crash.

Its like curing a hangover by drinking more alcohol. Yeah, it works, but its not really a solution.

I went to a sleep specialist and he told be people have two times during a 24hr period when your body tries to shut down and rest. ~10pm and 2pm. Nothing you can do about it, although having a 30min nap helps because you go through a complete sleep cycle including deep sleep and you’ll wake up refreshed.

It’s just how our body’s natural rhythm works. If you think about it, it makes sense that we should be resting during the hottest part of the day
