Article in English: Deep breaths are a fool-proof way to calm yourself down. Sit or lie down somewhere comfortable and close your eyes. Then, place your hand on your stomach and inhale slowly through your nose. Feel your stomach push your hand out as you inhale. Then, slowly exhale through your mouth. Repeat this several times. Feeling dehydrated or thirsty can make a high feel more intense. To hydrate yourself so you feel more calm and centered, fill up a glass with cold water and slowly sip on it. When you’re finished, assess how you feel and get more water if you’re still thirsty. Avoid drinking sodas, energy drinks, or alcohol or you could end up feeling more dehydrated. Sometimes sitting in a dark, stuffy room can make you feel a little on edge. If you’re indoors, try opening a nearby window to let in some fresh air and natural light. If there’s a nice view, sit by the window and look at the scenery — it might help calm you down so you can focus on getting over your high. Having something to listen to or watch can help distract you from any thoughts racing around in your head. If you have somewhere you need to be, leave the music or movie on in the background while you’re getting ready so you have something to listen to.  Listen to calm, happy songs that you already know and like. If you decide to put on a movie, go with something lighthearted like a comedy or a nature documentary. If you don’t have anywhere to be for the rest of the day, get comfortable in bed and try sleeping off your high. When you wake up, you’ll feel refreshed and you probably won't feel high anymore!
