Mindfulness practice and an understanding of the window of tolerance help us to regulate our emotions.

Mindfulness is present moment awareness. It means paying attention to our thoughts, emotions, and feelings in the body as they are happening and adopting an attitude of curiosity and compassion. 

The practice of mindful awareness can help us to feel better, especially if we're struggling with difficult emotions, fluctuations in our mood or physical pain. It is a skill of stepping into a mode of “being” present with whatever is happening, rather than reacting and getting stuck on autopilot.
