Calmness

Calmness is the mental state of peace of mind, being free from agitation, excitement, or disturbance. It also refers being in a state of serenity, tranquillity, or peace. Calmness can most easily occur for the average person during a state of relaxation, but it can also be found during much more alert and aware states. Some people find that focusing the mind on something external, such as studying, or internal, such as breathing, can be very calming.

Childhood origins
Parental soothing (by rocking, holding, etc.) in infancy lays the foundations of the capacity to self-calm. Thereafter transitional objects can help maintain calmness, while pets as also promote soothing and calm.

Cultivating calmness
Calmness is a quality that can be cultivated and increased with practice, or developed through psychotherapy. It usually requires training for one's mind to stay calm in the face of a great deal of different stimulation, and possible distractions, especially emotional ones. The negative emotions are the greatest challenge to someone who is attempting to cultivate a calm mind. Some disciplines that promote and develop calmness are prayer, yoga, tai chi, martial arts, theatre arts, gardening, relaxation training, breath training, and meditation. Jon Kabat-Zinn states that "Your mindfulness will only be as robust as the capacity of your mind to be calm and stable. Without calmness, the mirror of mindfulness will have an agitated and choppy surface and will not be able to reflect things with any accuracy."

Sarah Wilson recommends reducing one's exposure to choices/decisions as a route to calm.

Peace of mind
Another term associated with calmness is "peace". A mind that is at peace or calm will cause the body to produce less stress hormones; this in turn gives the person a stable emotional state and promotes good health in every area of life, including marriage. It is beneficial to stay calm, especially during stressful events.

Etymology
The term comes from Middle English calme, from Old French, from Old Italian calmo, from Late Latin cauma, "heat of the day", the "resting place in the heat of the day", from Greek, burning heat, from , to burn.
