Caffeine intake in various forms (and tastes as well!) is a common practice all around the world, especially since past few decades. Though people are gradually realizing that it can affect their health and mental performance, but only a fraction of people around the globe are actually able to alter their caffeine intake for such reasons. The degree of influence of caffeine might be a debateable issue, but one thing is for sure; its daily intake is associated with sleep problems and daytime sleepiness. The effects of caffeine on your health not only depend on the amount of caffeine ingestion at bedtime, but also on total caffeine intake throughout the day. Studies provide a pile of tips for better sleep but still many people are unaware of them.
Caffeine Intake in relation to age
This subject is not taken very frequently for studies, but still the studies have produced some results:
Caffeine intake in relation to jet lag and shift work
Jet lag and SWSD (shift work sleep disorder) can lead towards increased sleepiness and increased risks of injury. Results of another systematic review suggested that caffeine may prove effective in people working in shifts, for improving their performance. The same tendencies were also observed for people suffering from jet lag.
The studies conducted on how caffeine intake affects mental performance and sleep patterns are of initial level and need further exploration. However, one thing can be concluded for certain that caffeine consumption is capable of influencing not only sleep patterns in humans, but also their mental performances. So, if you are finding inconsistency in your sleeping patterns or cognitive functions, you better check your caffeine intake.
