“Decrease Anxiety in an Instant

The best way to instantly feel less anxious is to slow your breathing. Try this whenever you feel physically overaroused due to anxiety, or when your thoughts are either racing or frozen. Slowing your breathing will automatically slow down your heart rate. You’ll feel calmer. Since this is a physiological fact, it’s about the only anxiety strategy that has a 100% guarantee of working. The effect is nearly instant.
Here are some tips for slowing your breathing

1. Before you try to slow your breathing, drop your shoulders. It’ll make it easier. Also, focus on breathing slowly rather than breathing deeply.

2. If you have an area of tension in your body, like your neck and shoulders are tight, imagine you’re breathing fresh new air into those areas. There’s nothing sciencey about this, but lots of people like this method.”
