What is the opposite of anxious?

The opposite of anxious can be described as being calm, composed, or relaxed. When someone is not anxious, they generally feel at ease and are able to approach situations with a sense of peace and tranquility. They may be able to think clearly and make rational decisions without being overwhelmed by worry or fear. Additionally, people who are not anxious typically experience a lower heart rate and have a reduced level of cortisol, the stress hormone, in their bodies. It is important to note that being the opposite of anxious does not necessarily mean being completely carefree or without any concerns, but rather having a healthy ability to manage and cope with stressors in a more balanced way.
