Caffeine induced sleep disorder results from overconsumption of caffeine. If a person consumes caffeine immediately before bedtime or regularly throughout the day then the sleep delays, total sleep time reduces, normal stages of sleep later and the sleep quality decreases. High dose of caffeine in late evening sleep onset latency (length of time it takes to go from full wakefulness to sleep).

The amount of caffeine that is necessary to produce symptoms varies from person to person. Caffeine does not affect all people the same way. Although consuming caffeine regularly some people do not report any sleep problems.
Caffeine Is Harmful?
Through stomach and small intestine caffeine enters the bloodstream and produces the stimulating effect as soon as 15 minutes after consumption. When caffeine enters the body it persists for several hours and takes about 6 hours to eliminate the one-half of consumed caffeine. Caffeine reaches the brain and increases the secretion of norepinephrine that is associated with fight or flight stress response.
The increase in no epinephrine levels raises the activity of neurons in the brain and produce symptoms that resemble panic attack.
