Before stress gets the best of you, try these ways for calming down and counteracting the negative aspects of stress.
Exercise reduces anxiety and muscle tension.It also strengthens the cardiovascular system, raises HDL cholesterol, and helps to lower blood pressure.

Learn to relax: When you relax, your muscles relax so you feel less anxiety, your heart beats more slowly, and blood pressure is temporarily reduced.

Express what troubles you. Talk about problems with a friend, relative, or counselor. If you don’t want to share them with another person, write them down in a diary.
Put pleasure in your life. Stressful events can harm our bodies, but pleasurable ones may actually strengthen our immune systems.
