Are there ways to cope with panic attacks without having to take medicine?

Yes, therapy helps a lot. Take 10 deep breaths when you feel an attack is coming; you'll be amazed by its effect. Try identifying what is causing them and track what thoughts come to mind. Thoughts have a great impact on anxiety. Exercising is important too.

There are breathing techniques which can help to cope with panic attacks. I think it's important to clean your mind and think about reasons of your panic attack.

Retreat to a safe and calm zone. Take few deep breaths and close your eyes. Then try to think of something peaceful, like a meadow or a beach with its soothing waves. Block out the outside world and focus on your thoughts. Try to feel the positivity of those thoughts and connect with it. This works even beter if you've got some calm ambient music or ambient sounds, I've noted from personal experience. Especialy so with headphones since they usualy block out external noise. Enjoy the moment that you create for yourself and remember that free time is important, especialy in these digital, stressfull times.

Grounding techniques, breathing techniques guided by somebody (or reading a webpage too), sensory stimulation such as using a rubber band to snap against the wrist if one is about to have a panic attack or icing their hands to feel and to snap out of it.

I read somewhere that taking a deep breath and thinking of something that makes you happy works, so that's what I do and it actually helps

Person who has panic attack can try to breathe in and tense every muscle in body , be like that for 10 seconds and then relax and breathe out.

Deep breathing exercises work remarkably well. Just slowly count between one and two. One, breath in, two, breath out.

Breathing exercises are a really great way to help you cope with panic attacks. They're good in the short term, for helping you while having a panic attack. You can check out the panic attacks support guide on this website for more information about those! Another, more long-term way to get help is CBT (cognitive behavioural therapy) which helps you to face what causes your panic attacks, and addresses the issue directly to help change the way your brain reacts to these things in a more positive way, without involving medication.

By thinking about the good things in life - at the time we should try to remember the good time and we should try to remember the people we love .

Yes, taking deep breaths and listening to calming music has helped me a lot during my panic attacks.
