There are many safe non-drug remedies for anxiety, from mind-body techniques to supplements to calming teas. Some start working right away, while others may help lessen anxiety over time.

L-theanine (or green tea): Research shows that L-theanine found in green tea helps curb a rising heart rate and blood pressure, and a few small human studies have found that it reduces anxiety.

Exercise: Exercise is safe, good for the brain, and a powerful antidote to depression and anxiety, both immediately and in the long term.

Eat something, quick: Almost universally, people get more anxious and irritable when they are hungry. When you get an anxiety attack, it may mean your blood sugar is dropping. The best thing to do is to have a quick sustaining snack, like a handful of almonds along with a glass of water or a nice cup of hot tea.

Eat breakfast: Stop starving yourself. Source of Choline which is found in egg should be taken in breakfast as low levels of choline are associated with increased anxiety.

Eat omega-3s: Fish oils are good for the heart, and perhaps they protect against depression. In one study, students who took 2.5 milligrams a day of mixed omega-3 fatty acids for 12 weeks had less anxiety before an exam.
