Mindfulness means being present in the moment with your mind, your thoughts, and the environment around you.
Sometimes we get so caught up with thinking about the future or the past. Thinking about the future too much might mean feeling worried about a test coming up or getting so overwhelmed with a big project due in a week that you can't start. Thinking about the past too much could mean feeling upset with how you performed at a basketball game last night or wishing you did something different on your quiz. Mindfulness helps take those away. Instead, by being mindful, we focus on right now.
Practicing mindfulness on a regular basis encourages a number of positive health effects, including more positive emotions, stress reduction, stronger immune system, increased focus and attention, greater empathy and compassion for others, decreased levels of anxiety/depression, and greater emotional control.
