Caffeine Feedback Loop
If you have a busy schedule where you have no down time and only get the bare minimum of required healthy sleep, you are at risk for a caffeine feedback loop. It starts by having caffeine right before bed one time. You have trouble falling asleep and end up getting less sleep than normal. As a result, you’re tired throughout your busy day so you use caffeine to stay awake through the day and right up until you need to go to sleep. Because of the caffeine, you, again, have trouble falling asleep and must use caffeine the following day.
