During a high-stakes presentation or an uncomfortable conversation, relaxing is easier said than done – but calmness is one of the keys to confident body language. If you’re feeling especially nervous and tense, those feelings can manifest in your body language. Your shoulders and back might stiffen, and you may feel inclined to cross your arms or tap your foot incessantly. To combat these stress-induced movements, deep breathing exercises can help you ground yourself in the present moment. Taking in some deep breaths, visualizing your success, and even smiling before a big presentation can help you feel and appear calmer.
