Fast Anxiety Relief Techniques That NIMH and NCCIH Say Can Help

Quick answer: The quickest anxiety relief techniques on NCCIH's list are slow, deep breathing, progressive muscle relaxation and guided imagery. They aim to bring on the "relaxation response," which means slower breathing, lower blood pressure and a slower heart rate. No government page I read promises instant relief. NIMH adds that habits like less caffeine and enough sleep can reduce symptoms when paired with standard care.

This post sticks to what NIMH and NCCIH say. I left out "cure it in 60 seconds" claims, because I couldn't confirm them on an official site.

Medical note: This is general education, not medical advice. If you're thinking about suicide, call or text 988 (the 988 Suicide & Crisis Lifeline). In a life-threatening situation, call 911.

What is the relaxation response?

NCCIH describes relaxation techniques as practices that help bring about the body's relaxation response. It has slower breathing, lower blood pressure and a reduced heart rate. NCCIH calls it the opposite of the stress response.

That's the idea behind most "fast" tools. You don't think the worry away. You give your body a different signal.

Which techniques can you try?

NCCIH lists several. These three need no equipment:

  • Breathing exercises. You focus on taking slow, deep breaths. This is also called diaphragmatic breathing.
  • Progressive muscle relaxation. You tense different muscles in your body, then release the tension.
  • Guided imagery. You picture objects, scenes or events linked to calm, and try to create a similar feeling in your body.

The list also includes autogenic training, biofeedback-assisted relaxation and self-hypnosis. Those usually need more guidance or a device.

Do they actually work?

The evidence is encouraging but not perfect. NCCIH cites a 2018 review of 16 studies with 856 people who had anxiety disorders. It found relaxation therapy reduced symptoms of anxiety, depression, phobia and worry.

But NCCIH also notes that most studies had a high risk of bias. For stress in general, it cites a 2019 review with preliminary evidence that diaphragmatic breathing may help reduce stress.

So treat these as tools, not guarantees. If you want help with online care, see our guide to online therapy for anxiety.

What can go wrong?

NCCIH says relaxation techniques are generally considered safe for healthy people. Still, some people report more anxiety, intrusive thoughts or fear of losing control.

It also mentions rare reports of problems for people with epilepsy, certain psychiatric conditions, or a history of abuse or trauma. If that's you, ask your provider before you try them.

If a technique makes you feel worse, stop. You don't have to push through it.

Is it stress or an anxiety disorder?

NIMH says stress is the physical or mental response to an external cause. It can be short term or repeat over a long time. Anxiety is the body's reaction to stress, and it can occur even if there's no current threat.

Occasional anxiety is normal. But if it doesn't go away and starts to interfere with daily life, NIMH says you may have an anxiety disorder.

For the physical side of anxiety, see our guide to anxiety symptoms in adults.

What habits help over time?

NIMH says a healthy lifestyle can help combat anxiety, though it can't replace treatment. Researchers found that reducing caffeine and getting enough sleep can reduce anxiety symptoms when paired with standard care, like therapy or medication.

NIMH also says stress management techniques, like exercise, mindfulness and meditation, can reduce anxiety symptoms and enhance the effects of therapy.

Sleep is a big piece. See our guide to how to fix your sleep schedule.

When should you talk to a professional?

NIMH says to seek professional help when anxiety starts to cause problems at school, at work, or with friends and family. A primary care provider can refer you to a mental health professional.

For generalized anxiety disorder, NIMH says diagnosis requires worry that's hard to control on most days for at least 6 months, plus at least three symptoms. Only a provider can diagnose it.

NIMH says treatment typically involves psychotherapy, medication, or both. It calls cognitive behavioral therapy a "gold standard" type of therapy.
