Is your cup of coffee affecting your sleep?

A recent meta analysis showed that caffeine consumption reduced total sleep time by 45 minutes and sleep efficiency by 7%.

If you want to avoid reductions in total sleep time, coffee should be consumed at least 8.8 hours prior to bedtime. And a standard serving of pre-workout supplement (217.50 mg of caffeine) should be consumed at least 13.2 hours before bedtime.
