Alert state means being ready for something important. It can mean being extra aware of your surroundings and paying attention to what is happening around you. It can also mean that you are getting ready for a specific event or task that is important, like a test or a soccer game. When you are in an alert state, you might take deep breaths and try to stay calm. It might even mean getting a good night's sleep so you are more focused and ready for whatever comes your way.
