What is a common side effect of caffeine consumption?

Jitteriness is a well-known side effect of caffeine consumption. Caffeine is a central nervous system stimulant that can lead to increased alertness and energy levels. However, this stimulant effect can also cause physical symptoms such as tremors or jitteriness, particularly in individuals who are sensitive to caffeine or consume it in high amounts.

The body's reaction to caffeine can vary widely among individuals, but jitteriness is often one of the first noticeable effects. It arises from the stimulation of the nervous system, which can result in an adrenaline-like response, leading to increased muscle tension or uneasiness.

Other potential side effects of caffeine, while relevant, may not manifest as prominently as jitteriness. For instance, difficulty sleeping is also a common issue, especially if caffeine is consumed close to bedtime. However, jitteriness generally occurs more immediately after consumption. Detachment from surroundings and loss of consciousness are less commonly associated with caffeine and tend to occur under specific circumstances or in cases of overdose.
