Can caffeine cause insomnia?
It is possible, but whether caffeine brings on insomnia is specific to you. There is surprisingly little research on this exact connection, and caffeine affects insomnia in some people and not in others. The only reliable way to know your own answer is to track caffeine and insomnia together for two to three weeks and look for the pattern in your own data.
Why there's no one-size answer
What shapes how you feel has obviously not been studied, but more important, many combinations of things have simply not risen to the level of attention in scholarly research that is needed to say with certainty how they are related. Bodies differ. Caffeine might affect insomnia for another person and do nothing to you. The only data that settles it is your own.
How to find out for yourself
Tapestry makes finding out simple and private. You log caffeine and insomnia with a few taps a day, and after two to three weeks Tapestry shows you whether they actually move together, in your own data. Cirdia never stores your wellness data on its servers, so what you track stays private to you.
