If you live with anxiety or have experienced a panic attack, you know that certain situations, stressors, or even thoughts can sometimes set one off. But what about what you drink? Dietitians point out that specific beverages may provoke or worsen panic symptoms, especially in people who are already prone to anxiety. Here are three drinks to be mindful of if you're hoping to keep your nervous system calm.
Caffeinated coffee and energy drinks
Caffeine is probably the most well-known dietary trigger for anxiety. It works by blocking adenosine, a brain chemical that promotes relaxation, and by increasing the release of adrenaline. For someone with a panic disorder or generalized anxiety, even a modest amount of caffeine — a single cup of coffee or a standard energy drink — can be enough to spark a racing heart, jitteriness, and the sense of dread that often precedes a panic attack. Dietitians note that the effect varies from person to person, but if you notice that coffee leaves you feeling wired and uneasy, it may be worth cutting back or switching to half-caf or low-caffeine alternatives like green tea.
Alcoholic beverages
Alcohol is often used as a social lubricant or a way to unwind, but its relationship with anxiety is complicated. Initially, a drink can produce a sedative effect that feels relaxing. However, as the body metabolizes alcohol, blood sugar levels can fluctuate and the central nervous system can become more excitable. This rebound effect — sometimes called “hangxiety” — can set the stage for a panic attack hours after the last drink. Dietitians emphasize that even moderate drinking can disrupt sleep quality, and poor sleep is a well-known trigger for anxiety and panic.
High-sugar soda and sweetened beverages
Sugary drinks cause a rapid spike in blood glucose, which is often followed by a sharp crash. That drop can produce physical sensations that mimic panic: shakiness, dizziness, sweating, and a rapid heartbeat. For someone who is already anxious, these physical cues can be misinterpreted as the beginning of a full panic attack, creating a feedback loop. Dietitians recommend sticking with water, unsweetened sparkling water, or herbal teas to avoid this blood sugar roller coaster. If you crave sweetness, adding a splash of fruit juice to your water provides flavor with a gentler effect on blood sugar.
The bottom line: Beverages aren't the cause of panic disorder, but they can be potent triggers for many people. Being aware of how coffee, alcohol, and sugary drinks affect your body gives you a practical lever to reduce the frequency or intensity of panic episodes.
How to make changes without feeling deprived
If you think one or more of these drinks may be contributing to your anxiety, you don't have to quit cold turkey. Dietitians suggest a gradual approach: replace your second cup of coffee with a cup of decaf or a mild green tea, dilute soda with sparkling water to cut sugar in half, or set a “no alcohol after 8 p.m.” rule to minimize the rebound effect. Small, sustainable shifts are more likely to stick — and they may bring more calm into your daily routine.
