What can you do to help yourself become happy when you feel a little sad? Some vinegar醋may help.
Some scientists did a test on this. 28 people with depression抑郁症took part in it. The scientists put them into two groups. Every day, people had the same diet except that people in the first group had four spoons of vinegar while those in the second group only took one spoon. Four weeks later, the scientists tested the mental心理的health of everyone. The symptoms症状of depression went down by 42% for the first group and 18% for the second. At the same time, the level水平of vitamin $B_{3}$ went up by 86% for everyone in the first group. The scientists said that having more vitamin $B_{3}$ could help with depression. However, the scientists only studied 28 people for this. In the future, they will need to test more people for the result.
If you don't want to do the test on yourself, here are some other things for you to try when you are feeling down. First, spend 45 minutes doing exercise, like running or walking. Do this three times a week. Second, keep healthy eating habits. Try to have less sugar. Eat fruit, not sweets. Third, write down your happy moments once or twice a week. It helps you to look at the bright side of life. At last, go to see a doctor when self-help does not work.
