Does caffeine affect sleep?
As caffeine is a mild stimulant, some people find that after drinking regular coffee in the evening, it takes longer to get to sleep. Other people happily drink their coffee after an evening meal without any such problems. Indeed, research has shown that individuals vary greatly in their sleep responses to coffee and that other factors like noise, temperature and stress are as likely to postpone sleep. So it is largely a matter of individual sensitivity. Decaffeinated coffee is available for those who are particularly sensitive to caffeine.
