This side effect can be distracting and even make it difficult to focus on tasks. For example, those who drink coffee may find their hearts racing and have difficulty controlling their thoughts.

When drinking coffee, it is important to consider these side effects and be aware of the possible feelings of intense stimulation.

Anxiety and the Dreaded Caffeine Jitters

Caffeine jitters are especially common in people who are prone to anxiety. It can cause physical symptoms that contribute to feelings of stress and worry. For people already experiencing anxiety, caffeine amplifies those symptoms and can make the anxious state worse.

Sleep Deprivation


Consuming coffee close to bedtime can interfere with sleep. Caffeine is a stimulant, so it can make it difficult to fall asleep, stay asleep, and get benefits from sleep.

It is best to avoid drinking coffee close to bedtime and avoid sleeping in if waking up with coffee is an established habit. This can ensure you are receiving enough rest and avoiding the side effects of coffee-related sleep deprivation.

Caffeine Can Aggravate Gut Problems

Caffeine can be a cause of concern for those with irritable bowel syndrome (IBS) or other gut issues. Common side effects can worsen as a result of excess caffeine intake. These side effects include heartburn, indigestion, abdominal pain, nausea, and bloating.

Caffeine increases intestine contractions, which can be incredibly painful for those with IBS, and although the effect is short-lived, the pain can be intense the more caffeine a person consumes. Caffeine can also stimulate the release of stomach acids and can cause relaxation of the esophagus, leading to heartburn and acid reflux.
