in (one's) comfort zone

1. In a place, activity, situation, or psychological state in which a person feels free from anxiety and is within their normal level of ability, experience, security, or control. I know it's not in your comfort zone, but traveling to a foreign country can give you a much better perspective on how other people in the world live. I've been in my comfort zone for way too long with this job. It's time to take some risks and see what else is out there for me! Going on a blind date is definitely not in my comfort zone, but I'm tired of being alone.

2. Within the temperature range that feels naturally comfortable to a person's body, being neither too hot nor too cold. When I retire, I'm definitely moving to Florida. The balmy weather there is more in my comfort zone than Minnesota, that's for sure. Thank you for turning the heat up—now we're in my comfort zone.
