Overindulging in caffeine can lead to unwanted side effects such as jitters, restlessness, insomnia, and more. Learn about these eight signs of too much caffeine and consider adjusting your intake if needed.
In moderation, caffeine can be a fantastic pick-me-up. It gives you the extra jolt to power through a sluggish afternoon or cram for that final exam. But like many things in life, too much can bring trouble. Here are eight signs you may have overindulged in the world's favorite stimulant.
1. Jitters and Restlessness
Caffeine is a stimulant that increases alertness. However, when you have too much, you may feel jittery or restless. These symptoms can range from a simple twitch in the leg to feeling like you can't sit still or are vibrating from the inside out.
2. Rapid Heartbeat
Excessive caffeine can stimulate your heart, causing it to beat faster than usual. In some cases, this may feel like your heart is racing or pounding in your chest, a sensation known as palpitations.
Caffeine can make it hard to fall asleep or stay asleep, leading to insomnia. This stimulant can stay in your system for up to 10 hours, so even an afternoon coffee break can interfere with your nightly rest.
4. Digestive Problems
Too much caffeine can lead to stomach upset or make existing gastrointestinal issues worse. This is because caffeine stimulates the production of stomach acid and relaxes the muscles that keep stomach acid contained.
This may seem counterintuitive since caffeine is known for providing an energy boost. However, as the caffeine wears off, a 'crash' often follows leading to feelings of extreme fatigue.
While moderate caffeine intake can help ward off a headache, too much can actually cause them. This is due to the effect caffeine has on blood flow in the brain.
In excess, caffeine can lead to feelings of anxiety, irritability, and nervousness. This can lead to a vicious cycle as anxiety can often interfere with sleep, and sleep deprivation can, in turn, exacerbate feelings of anxiety.
7. Psychological Symptoms
Although not as severe as many drug dependencies, caffeine dependence can still lead to withdrawal symptoms like headache, fatigue, and irritability when you try to cut back.
Everyone’s sensitivity to caffeine is different, and what may be okay for one person could be an excessive amount for another. If you're experiencing any of these symptoms, it may be time to consider cutting back on your caffeine consumption. But this doesn’t mean you’ll have to give up coffee all together!
