Restlessness is your nervous system stuck in a low-grade alarm state, flooding your body with stress hormones and signaling chemicals that make stillness feel impossible. The good news: you can interrupt this cycle quickly with the right techniques, and address the deeper causes over time. Whether your restlessness is physical, mental, or both, there are concrete steps that work.
Why Your Body Won’t Let You Be Still
Restlessness isn’t just “being antsy.” It has a specific biological signature. When you’re stressed or anxious, your brain releases cortisol, which in turn triggers dopamine surges in the brain’s reward and motivation center. The more cortisol your body produces, the more dopamine fires, and this combination creates that wired, driven-to-move feeling. It’s essentially your fight-or-flight system telling your muscles to do something, even when there’s nothing to run from.
This system is more reactive in some people than others. Early life experiences, genetics, and chronic stress all shape how strongly your brain responds to perceived threats. If your baseline stress response runs hot, you’ll feel restless more often and more intensely, even in situations that seem objectively calm.
Calm Your Nervous System in Minutes
The fastest way to counter restlessness is to activate your vagus nerve, the long nerve running from your brainstem to your gut that acts as a brake pedal for your stress response. These techniques work within minutes:
Slow diaphragmatic breathing. Breathe in deeply, filling your belly rather than your chest. Hold for five seconds, then exhale slowly. Repeat for one to two minutes. This directly slows your heart rate and signals your brain that the threat has passed.
Cold water on your face. Splash cold water on your face or hold a cold pack against your cheeks and neck for a couple of minutes. Sudden cold exposure triggers a reflex that slows your heart rate and redirects blood flow to your core. It’s one of the fastest physical resets available.
Humming or chanting. The vibration of humming, singing, or repeating a single sound activates the vagus nerve through the muscles of your throat. It sounds strange, but even 60 seconds of steady humming can noticeably shift your state from agitated to calmer.
Laughter. A real belly laugh stimulates the vagus nerve and releases tension across your whole body. Watch a short comedy clip or call someone who makes you laugh. It doesn’t need to be forced, but even exaggerated laughing can trigger the physiological response.
Progressive Muscle Relaxation
When restlessness lives in your body as tightness, fidgeting, or a buzzing sensation you can’t shake, progressive muscle relaxation (PMR) is one of the most effective tools. It takes 10 to 15 minutes and works by deliberately tensing each muscle group, then releasing it. The contrast teaches your nervous system what relaxation actually feels like.
Find a comfortable position sitting or lying down. Start at your feet or your face and work systematically through your body. Clench your fists and hold for five to ten seconds, then release. Bend your elbows and tense your biceps, then release. Straighten your arms to tense the backs of your arms, then release. Move to your forehead (wrinkle it into a frown), your eyes (squeeze them shut), your jaw (gently clench), your tongue (press it against the roof of your mouth), your lips (press them together), and your neck (gently press it back). Do one muscle group at a time, and pay close attention to the difference between the tense and relaxed states. By the time you’ve worked through your whole body, the restless energy typically drops significantly.
Move More Often During the Day
Sitting for long stretches is one of the most reliable triggers for restlessness. Your body is designed to move regularly, and prolonged stillness creates a buildup of physical tension that your brain interprets as a need to fidget or shift. A meta-analysis of randomized trials found that breaking up sitting time at least every 30 minutes is the ideal frequency for counteracting the effects of being sedentary.
These breaks don’t need to be long or intense. Standing up, walking to another room, doing a few stretches, or even just shifting positions resets the cycle. The key is frequency, not duration. Five movement breaks spread across a workday will do more for your restlessness than one long workout followed by eight hours in a chair. If you struggle to remember, set a recurring timer on your phone.
Screen Time and Nighttime Restlessness
If your restlessness peaks in the evening or keeps you from falling asleep, screens are a likely contributor. Blue light from phones, tablets, and laptops suppresses the sleep hormone your brain produces as it gets dark, keeping your nervous system in an alert, wakeful state. A systematic review found that three hours of blue light exposure before bed was enough to measurably decrease sleep quality. That means if you’re in bed by 10 p.m., dimming screens or switching to a blue light filter by 7 p.m. gives your brain the best chance to wind down naturally.
If cutting screens three hours early isn’t realistic, even one to two hours makes a difference. Blue light filtering glasses and “night mode” settings on devices reduce exposure, though they don’t eliminate it entirely.
Check Your Iron Levels
Restlessness that shows up mostly in your legs, especially at night or when you’re sitting still, may point to restless legs syndrome (RLS). The hallmarks are an irresistible urge to move your legs, uncomfortable sensations that start or worsen at rest, temporary relief from walking or stretching, and symptoms that are worse in the evening and at night.
Iron deficiency is one of the most common and treatable causes of RLS. The International Restless Legs Syndrome Study Group defines iron deficiency for adults with restless leg symptoms as a serum ferritin level below 75 µg/L, which is higher than the threshold used for general iron deficiency. Many people with ferritin in the “normal” range of 20 to 50 are still low enough for it to drive restless legs. If this pattern sounds familiar, a blood test checking your ferritin level (not just hemoglobin) is worth requesting. Iron supplementation often improves symptoms when levels are low.
When Restlessness Is Actually ADHD
In children, ADHD looks like bouncing off the walls. In adults, it often looks like internal restlessness: a constant feeling of being driven, difficulty sitting through meetings, fidgeting, and a mind that won’t stop jumping between thoughts. The American Psychiatric Association notes that hyperactivity in adults frequently appears as extreme restlessness and a persistent feeling of being fidgety rather than the obvious physical hyperactivity seen in kids.
If your restlessness has been present since childhood, shows up across multiple areas of your life (not just during stressful periods), and comes paired with difficulty focusing, impulsive decisions, or trouble completing tasks, it may be worth exploring an ADHD evaluation. The restlessness of ADHD doesn’t respond well to relaxation techniques alone because it stems from differences in how the brain regulates attention and arousal.
When Medication Is the Cause
A specific, intense form of restlessness called akathisia is caused by certain medications, particularly antipsychotic drugs. It feels like a deep internal jitteriness with an overwhelming compulsion to move, especially in the legs. People with akathisia cross and uncross their legs repetitively, rock back and forth, or pace constantly. Unlike general anxiety, akathisia doesn’t involve fear or worry. It’s purely a motor-driven urge.
Akathisia is the most common movement side effect of antipsychotic medications. It’s more frequent with older, first-generation antipsychotics, where rates reach as high as 45%, but it also occurs with newer medications. Symptoms typically appear shortly after starting a new medication or increasing a dose. If you’ve recently started or changed a psychiatric medication and suddenly feel unable to sit still, that timing is a strong clue. Dose adjustments or medication switches can resolve it.
Supplements That May Help
Ashwagandha has the strongest evidence base among herbal supplements for reducing the kind of restlessness tied to stress and anxiety. An international task force created by the World Federation of Societies of Biological Psychiatry recommends 300 to 600 mg per day of ashwagandha root extract (standardized to 5% withanolides) for generalized anxiety. Several studies have found that benefits are greater at 500 to 600 mg per day compared to lower doses. Effects typically take two to four weeks of daily use to become noticeable.
L-theanine, an amino acid found naturally in tea, promotes calm alertness without drowsiness. It’s widely available and generally well-tolerated, though clinical evidence for restlessness specifically is less robust than for ashwagandha. Magnesium is another common recommendation, particularly for people whose restlessness involves muscle tension or leg discomfort, though supplementation is most effective when you’re actually deficient.
Building a Long-Term Routine
Occasional restlessness responds well to the quick techniques above. Chronic restlessness usually requires layering multiple strategies into your daily life. A practical starting framework: move your body every 30 minutes during the day, practice slow breathing or PMR once daily for 10 to 15 minutes, reduce screen exposure in the evening, and address any nutritional gaps (particularly iron and magnesium). Gentle daily exercise like walking, yoga, or stretching helps regulate your baseline stress response over time, making you less reactive to the triggers that set off restlessness in the first place.
If these strategies don’t make a meaningful difference after a few weeks, that persistence is useful information. Chronic, treatment-resistant restlessness often points to an underlying condition like ADHD, RLS, a medication side effect, or an anxiety disorder that benefits from targeted treatment rather than general coping strategies.
