Colors can influence a person's mind and body. According to scientists，colors can change feelings，influence behavior and even cause physical reactions(反應(yīng))．

Research shows that babies cry more in yellow bedrooms，and families are easier to fight in yellow kitchens. But yellow isn't all bad. The color is known to improve confidence and learning. A yellow classroom may be good for your headache，and at the same time it might actually help you solve those challenging math problems.

Other colors also have helpful effects on people. For example，blue helps the body relax，and orange tends(趨向于) to improve a person's mood and make a person want to eat.

Colors were used to treat illnesses. Four thousand years ago，the Egyptians built healing temples of light，which filtered(過(guò)濾) some of the sun's rays(光線) and bathed patients in some colors to treat some illnesses.

Recently，studies have shown that colors can influence us though we don't see them. Kurt Goldstein，a famous scientist，is sure that a blindfolded(蒙住眼的) person will experience physical reactions under rays of different colors. In other words，the skin reads colors，and our bodies，minds and emotions reply to them.

Have you ever been so worried about something that you have a headache or even can't sleep at night？Then you cannot pay enough attention during a test or in your study. If so，then you know that is stress. You are worried too much about something. The bad feeling in your mind can make you angry，sad or scared，and even can give you a stomachache or a headache.

However，some kind of stress is good. Excitement might happen when you are called to give a speech at school. You feel nervous but excited. This kind of stress can help you to get things well done. And you may do a better job in your test if the stress pushes you to prepare more beforehand.

On the other hand，bad stress can last long if you are unable to solve your problems. You may not feel well，if your parents are having a quarrel，if a family member is badly ill，if you're doing poorly at school，or if anything else makes you unhappy. This kind of stress isn't going to help you. And it can actually let you down in your daily life.

The best way to fight the stress is to have a balanced life. Make sure you get enough sleep and eat properly. Have some regular exercise. You should take some time for fun. Get advice from your parents，teachers and friends. Soon after that，you'll probably get away from your stress.

How many times do you check your WeChat Moments or micro blog in a day to see whether your latest post has got another “l(fā)ike”？Although you might not be willing to admit how many times you have done so，don't worry，a new study has shown that it's completely normal.

According to the University of California，which searched teenagers aged between 13 and 18，the pleasure they get from a “l(fā)ike” is the same as that of eating chocolate or winning money，and they can't help waiting more. The research also shows that although the “l(fā)ike” might come from strangers，the pleasure they get from it works all the time.

Why is it that so many young people want the excitement of seeing that little “thumbs up” on their screen？The article “Why do people desire attention？” explains several cases in which people naturally long for attention. It says that people who were an only child and were used to being the center of attention in their house may try to live in these conditions again. Feeling “ignored and unappreciated(不被欣賞的)” might also lead to wanting attention. Also，“when you're waiting for someone else to confirm(確認(rèn)) that what you're doing is cool，you're basing your opinion of yourself on their values，not your own，” US psychologist(心理學(xué)家) Bryan said.“ The further you go from your own center，the unhappier you'll feel.” So how can you fix this？Well，the most important thing is to remind yourself that social media can be a way of getting some empathy(共鳴)，but the world doesn't move around you.
