5 quick and simple ways to eliminate stress:
1. Breathing Exercises (e.g. box breathing, or other slow nasal belly breathing techniques)
2. Short Intense Exercise
3. Adopting a 3rd Person Perspective
4. Change your visual environment (including utilising peripheral vision and fractals)
5. Cold Water Therapy (a hormetic stress)
These techniques will help you switch from a fight or flight state into rest and digest mode. However, they are not a substitute for addressing the root causes of your stress.
