Can Caffeine Cause Anxiety?
Research suggests that caffeine consumption may cause or worsen anxiety.1 Similarly, high caffeine intake also causes sleep deprivation, which is a known cause of anxiety disorders.
Caffeine is one of the most consumed drugs in the world.2 Globally, people consume caffeine in tea, coffee, energy drinks, and even soda.
Because caffeine increases alertness and concentration, workers who need an energy boost consume caffeinated drinks to improve awareness and productivity. In the same vein, students are also heavy caffeine consumers.
For one, students who need to stay up all night consume caffeine to study for tests and exams. This stimulant prevents sleep by blocking adenosine, which is responsible for drowsiness.3 When it blocks this receptor, you may not sleep for an extended period.
Further, students consume numerous beverages, which contain caffeine. To promote alertness and concentration, they drink sodas, coffee, and energy drinks. This is a cause for concern for health professionals, especially with numerous schoolchildren consuming daily doses of caffeine in the form of soda.
While caffeine is not harmful, consuming large amounts would likely bring undesired results. Experts recommend consuming 400mg or lesser of this stimulant to prevent unwanted side effects. Drinking an amount more considerable than this may also trigger anxiety or other mental health illnesses.
Since caffeine is a culprit of sleep deprivation, there is a possibility that it may cause anxiety. Sleep deprivation is a state of not getting sufficient hours of sleep. When you are not sleeping well, you may become anxious and restless.4
While most studies have not been able to link caffeine as a direct cause of anxiety, several reports show that anxiety may worsen anxiety, particularly in children.
According to a study based on schoolchildren from South West England, children who consumed higher than 1000mg per week of caffeine experience increased stress, depression, and anxiety.5
From the analysis, anxiety may also trigger other mental health challenges, making it essential to cut your child’s caffeine consumption.
