This finding shows that caffeine interferes with a modulatory mechanism in sleep regulation rather than a fundamental sleep regulatory brain circuit. Ultimately, regular sleep habits are important in overall quality and timing of sleep. Caffeine consumption
Overconsumption
Although the maximum daily consumption of caffeine varies with consideration of couple of aspects such as sex, age, race, physical activity and smoking, excessive ingestion of caffeine can lead to a state of intoxication. This period of intoxication is characterized by restlessness, agitation, excitement, rambling thought or speech, and even insomnia. Even doses of caffeine relating to just one cup of coffee can increase sleep latency and decrease the quality of sleep especially in non-REM deep sleep. A dose of caffeine taken in the morning can have these effects the following night, so one of the main practices of sleep hygiene a person can do is to cease the consumption of caffeine. Moderation
Keeping in mind that caffeine content in beverages and food varies and that some individuals are more sensitive to caffeine consumption than others are, moderation of caffeine is key. Between 200 and 300 mg of caffeine is considered "moderate" for most adults. While children can consume caffeine, it is advised to refrain children and adolescents from consuming caffeine due to their growing brains and to allow them to develop healthy sleep patterns. Consequences of sleep disruption
Normal healthy sleep is described as having sufficient duration, quality, timing, regulation, and the absence of sleep disturbances or disorders.
Long-term consequences of sleep disruption include: cardiovascular problems such as cardiovascular disease, hypertension, higher concentration of fats in the body, weight issues such as metabolic syndrome, increased likelihood of cancer, and gastrointestinal disorders. References
