How Much Is Too Much?
Anxiety is part of life — we all feel it from time to time. When you do, there are a few things you can try to help calm your emotions. If you feel anxious often and nothing seems to help, talk with your doctor about other ways to manage it.

Exercise
You don’t have to train for the Olympics — a 10-minute walk can do the trick just as well as a 45-minute workout. Either can make you feel better for a few hours, like aspirin for a headache. And if you exercise regularly — at least 3 times a week — you’re less likely to feel anxious in the first place.

The Great Outdoors
Even a plant in the room, or pictures of nature, can make you feel less anxious, angry, or stressed. But it’s better if you get out there. You’ll give your mood a boost, and it can lower your blood pressure, heart rate, muscle tension, and stress hormones, which all go up when you’re anxious.

Gardening
Get out there and get your hands in the dirt. Gardening makes your brain release mood-boosting chemicals that can help calm your anxiety. Plus, you’ll get some exercise and spend time outdoors, both of which can be good for you, too. If you don’t have your own dirt patch, call a local community garden — they’ll be happy for the help.
