![]() Long-term poor or inadequate sleep is linked with a higher risk of chronic illnesses like type 2 diabetes, heart disease, obesity, and dementia ( 6, 7).Įxperts recommend sleeping 7–9 hours per night ( 8). Regularly getting adequate sleep is not only effective for preventing caffeine crashes, but it’s also important for good health. As such, prioritizing sleep may be a way to eliminate or reduce your reliance on caffeine to keep you awake and alert, thus preventing caffeine crashes ( 5). The energizing effects of caffeine are stronger when you’re sleep deprived than when you’re well rested. This pattern has been called the “coffee cycle,” and over time, it can lead to excessive use of caffeine ( 4). In response, you may consume more of the substance. Once the effects wear off, you may feel more tired than before. Many people turn to caffeine - whether from coffee, soda, or energy drinks - to increase alertness and promote wakefulness in the morning or throughout the day, especially after a poor night’s sleep.Īlthough achieving a good night’s rest may not be possible every night, it’s essential for preventing caffeine crashes.Ĭonsuming caffeine when tired or energy-deprived will only temporarily relieve those feelings. It’s associated with tiredness, the inability to concentrate, and irritability. summaryĪ caffeine crash can result due to poor sleep, consuming caffeine close to bedtime, or consuming too much. ![]() Here are 4 tips to help you avoid a caffeine crash.

The half-life of caffeine varies among individuals. ![]() Use parenthesis!)ĭetermine the amount of caffeine remaining in the bloodstream: (Be careful when entering fractional exponents in the calculator. Use the function you wrote in #2 to check your answers for the table in #1. What does your exponent need to represent? How can you determine this exponent if you know the number of hours that have passed? Write an exponential function f to model the amount of caffeine remaining in the bloodstream t hours after the peak level. (You can return to your answers later to make any corrections if you find your strategy was incorrect.) Explain how you came up with your answers. How much caffeine will remain in your bloodstream after 5 hours? 10 hours? 1 hour? 2 hours? Record your answers in the table. Suppose the caffeine in your bloodstream peaks at 80 mg. Suppose you drink a 16-ounce drink that contains 80 mg of caffeine.
