4 Ways to Fight Depression
If you feel depressed, it's best to do something about it — depression doesn't just go away on its own. In addition to getting help from a doctor or an expert, here are 4 things you can do to feel better.
1. Exercise. Take a 15- to 30-minute walk every day — or dance, jog, or bike if you like. In addition to getting these exercises, some yoga poses can help relieve feelings of depression. Try downward-facing dog or legs-up-the-wall pose (you can find these poses on yoga websites). Two other aspects of yoga — breathing exercises and meditation(冥想) — can also help people with depression feel better.
2. Mind your food. _______________ can affect appetite. One person may not feel like eating at all, but another might overeat. Proper food can influence a person's mood and energy. So eat plenty of fruits and vegetables and get regular meals (even if you don't feel hungry, try to eat something light, like a piece of fruit, to keep you going).
3. Identify troubles. Try to identify any situations that have made you depressed. Once you find out the causes, turn your attention to something positive. Take action to solve problems. Ask for help if you need it. Feeling connected to friends and family can help relieve depression. (It may also help them feel there's something they can do instead of just watching you hurt. )
4. Look on the bright side. Depression affects a person's thoughts, making everything seem unhappy and hopeless. If depression has you noticing only the negative, make an effort to notice the good things in life.
Most of all, don't forget to be patient with yourself. Depression takes time to heal.
