Coffee, a popular and social beverage worldwide, particularly in the West, is a drink made from roasted beans from the Coffea plant, native to tropical Africa and Madagascar.

A total of 7698 subjects aged 11-17 years were included in the investigation of a cross-sectional study within the German Health Interview and Examination Survey for Children and Adolescents. Self-report questionnaires returned by participants showed that
1. Frequent coffee consumption, accompanied by high alcohol intake and frequent smoking may be associated with the prediction of IC in male subjects
2. Frequent coffee consumption and high alcohol intake also induced the predicted occurrence of insomnia IC in females.

After taking into account other factors, researchers emphasized that coffee consumption may be an essential risk factor for IC in adolescents. They had a significant affects on the association of smoking, alcohol, and marijuana with IC.


Additionally, in the study conducted by the Instituto Politécnico de Viseu included 6,919 students from the 7th to the 12th grade from 26 secondary schools, in 2012 with data collected, using a self-administered questionnaire, researchers filed the following results
1. The prevalence of symptoms of insomnia was 21.4 %, and the prevalence of insomnia was 8.3 %
2. After adjustment for gender and age, insomnia affects mostly the female gender
3. Coffee and alcohol consumption showed a significant risk of insomnia with an adjusted relative risk of 1.63

According to the finding information, Dr. Amaral MO, the lead author said, " The main risk factors for insomnia among these adolescents are gender (female), age (≥ 16 years), depression, and coffee and alcohol consumption, which is also in concordance with those in the literature".

Furthermore, in rats, radiotelemetry transmitters with electroencephalogram and electromyogram electrodes implanted for sleep recording in animals administered with caffeine alone (10 mg/kg) or in combination with zolpidem (10 mg/kg) or trazodone (20 mg/kg), or vehicle, in crossover experiments with 12 healthy male volunteers in a randomized, placebo-controlled, 4-week crossover study, caffeine injection group showed a significant prolongation in objective sleep onset latency (SOL) with disruption in subjective measures of sleep onset caused by the caffeine in rats and humans in compared to other groups.

Taking together, coffee and coffee caffeine may have a disruptive effect on induced insomnia and symptoms of insomnia, particularly in female, therefore women who have a history of insomnia should reduce intake of coffee or only drink them in the morning at a reduced amount.
