Chewing gives your brain a focused sensory task that can interrupt anxious thoughts and lower stress hormones. In one study, chewing gum during a stressful situation significantly reduced both self-reported anxiety and cortisol, the body’s primary stress hormone. The good news is you have plenty of options beyond gum, from purpose-built chew tools to everyday foods that deliver satisfying oral input.
Why Chewing Helps With Anxiety
When you chew, your jaw muscles send a steady stream of sensory signals to your brain. This activates areas involved in motor control, sensory processing, and attention. Harder foods and objects recruit even more brain regions, including areas linked to focus and planning. That wave of organized input essentially gives your nervous system something concrete to process instead of cycling through worry.
Chewing also fits into a broader category called body-focused repetitive behaviors. According to the stimulus regulation model, these behaviors help people manage internal sensory imbalance. If you’re overstimulated by anxiety, the rhythmic, predictable motion of chewing can act as a release valve. If you’re understimulated and restless, it provides just enough input to settle you. People with ADHD or heightened sensory sensitivity are especially likely to seek this kind of oral input, though anyone under stress can benefit from it.
Chew Tools Designed for Adults
Silicone chew necklaces (sometimes called “chewelry”) are the most popular dedicated option. They’re made from food-grade silicone, look like regular jewelry, and come in different firmness levels to match how intensely you chew. ARK Therapeutic, one of the better-known brands, uses a color-coded system with three tiers:
- Soft/Standard: The chewiest option, good for mild chewing if you’ve never bitten through a pen cap or chewed holes in shirt collars.
- Medium Firm (XT): Similar in firmness to a classic pink eraser. Works well for moderate chewers who occasionally wear through softer materials.
- Super Firm (XXT): Rigid but still chewable. The longest-lasting option for people who chew aggressively or frequently throughout the day.
If wearing a necklace isn’t your style, similar silicone comes in pen toppers, bracelet forms, and small handheld shapes that fit in a pocket. The key advantage over random objects like pen caps or fingernails is that these tools are designed to hold up to repetitive chewing without breaking apart into choking hazards.
Chewing Gum
Regular chewing gum is the simplest, most socially invisible option. Research published in the journal Psychopharmacology found that gum chewing during a controlled stress test improved alertness while reducing anxiety and cortisol levels. The effect held across both mild and more intense stress conditions.
For anxiety specifically, firmer gum tends to provide more satisfying input because it makes your jaw muscles work harder, sending stronger sensory signals. Sugar-free varieties with xylitol have the added benefit of not contributing to tooth decay if you’re chewing frequently. Mint-flavored gum pulls double duty: the strong taste engages your sense of smell and taste alongside the mechanical input, which is essentially a mini grounding exercise built into a stick of gum.
Foods That Provide Oral Sensory Input
If you’d rather eat something than chew on a tool, certain foods deliver the same kind of heavy sensory feedback your jaw craves during anxious moments. Crunchy and hard-textured foods activate more brain areas than soft ones, making them better at redirecting your attention.
Good crunchy options include raw carrots, celery, apples, nuts, pretzels, and rice cakes. These require sustained chewing and produce satisfying sounds and textures that engage multiple senses at once. Chewy options like dried fruit, beef jerky, or sourdough bread work differently: they keep your jaw engaged for longer with each bite, providing a slower, more rhythmic form of input. Ice is another popular choice. Crunching ice delivers intense cold alongside the mechanical sensation, though dentists generally advise against it because it can crack tooth enamel over time.
Keeping a small bag of baby carrots or almonds at your desk gives you something to reach for the moment anxiety starts building, before it has a chance to escalate.
Chewing as a Grounding Technique
Chewing fits naturally into grounding exercises used for panic and acute anxiety. The well-known 5-4-3-2-1 technique asks you to engage each of your five senses to anchor yourself in the present moment. Taste is one of those senses, and chewing something flavorful checks both the taste and touch boxes simultaneously.
You can make any chewing option more effective by paying deliberate attention to the experience. Notice the texture against your teeth, the flavor changing as you chew, the tension and release in your jaw muscles. This turns a simple habit into a mindfulness exercise, which compounds the calming effect. Even noticing what the inside of your mouth tastes like right now, without adding anything, can serve as a quick reset during a wave of anxiety.
Protecting Your Jaw
There’s one real downside to relying on chewing for anxiety relief: your jaw joint wasn’t designed for hours of continuous use. The temporomandibular joint (TMJ) connects your jaw to your skull, and overworking it can lead to pain, clicking, stiffness, or difficulty opening your mouth fully. Cleveland Clinic lists habitual chewing on pens, ice, and nails as behaviors that can worsen TMJ problems.
A few practical guidelines can help you get the anxiety benefit without the jaw strain. Alternate between chewing and other sensory strategies like squeezing a stress ball or rubbing a textured stone. If you notice soreness in your jaw, temples, or in front of your ears, take a break for the rest of the day. Softer chew tools and gum are gentler on the joint than hard foods or firm silicone, so if you’re chewing for long stretches, go softer rather than harder.
Picking the Right Option for You
The best thing to chew on for anxiety is whatever you’ll actually have with you when anxiety hits. A chew necklace works well if you experience anxiety throughout the day and want something always within reach. Gum is better if you need something discreet for meetings or social situations. Crunchy snacks make sense if your anxiety tends to spike at predictable times, like mid-afternoon at work, when you can plan ahead.
Some people rotate between options depending on the setting. A pen topper at the office, a chew pendant at home, carrot sticks during a study session. The underlying mechanism is the same in every case: you’re giving your brain organized sensory input that competes with the disorganized noise of anxiety. The chewing itself is the active ingredient, not the specific object.
