How does caffeine affect sleep?

Caffeine can impact the onset of sleep and reduce sleep time, efficiency, and satisfaction levels . Older adults may also be more susceptible to caffeine-induced sleep troubles. Caffeine notably reduces the time of slow-wave sleep  , which is the stage of deep, restful sleep that leaves us feeling refreshed and alert in the morning. Caffeine-interrupted sleep can lead to  sleep deprivation the following day, which is characterized by fatigue and problems with learning, memory, problem-solving, and emotion regulation. One study examined the effects of caffeine intake zero, three, and six hours before bedtime, and found that even caffeine consumed six hours before bed  could reduce sleep time by one hour. In addition, study participants reported sleeping problems when consuming caffeine 0-3 hours before bed, but they did not realize their sleep was also disrupted when consuming caffeine six hours before bed.

Some say that your last cup of coffee should be by 2-3pm. Is that right?

Ideally caffeine has to be avoided with any meal as it will become hurdle in nutrient absorption so try not to have it before, after or along with meals. As mentioned in post too that avoid before 6 hrs going to bed. So if you go to bed by 10pm then last cup of coffee should be before 4pm
