A good percentage of Humans are prone to mass delusions which lead to irrational behavior. This is a known bug in our operating system, and we have designed some parts of our society to protect us against it.

If you have the time to learn only one technique, this is the one to try. In coherent breathing, the goal is to breathe at a rate of five breaths per minute, which generally translates into inhaling and exhaling to the count of six. If you have never practiced breathing exercises before, you may have to work up to this practice slowly, starting with inhaling and exhaling to the count of three and working your way up to six.

1. Sitting upright or lying down, place your hands on your belly.
2. Slowly breathe in, expanding your belly, to the count of five.
3. Pause.
4. Slowly breathe out to the count of six.
5. Work your way up to practicing this pattern for 10 to 20 minutes a day.

This is the fastest way that I'm aware of that's anchored in real known biology to calm oneself down… It's an inhale through the nose, and the it's another inhale on top, and then a long exhale. That's the fastest way to slow your heart down and calm down.
