When your friend has a bad day，what will you do to make him or her feel better？ "Hugging can help them feel better，" Time reported.
    According to scientists from Carnegie Mellon University in the US，hugs can be good for a person's feelings and stress levels.Hugging can make good feelings，

criticism （批評） may bring bad feelings.
    Researchers talked to about 400 people.They asked them about their feelings，whether they had any arguments with others and if they had a hug that day.They found that when people experienced arguments but didn't get any hugs，they had more negative feelings.But when people had both on the same day，they had more good feelings and fewer bad feelings.
    When you receive a hug，your body produces a certain hormone （荷爾蒙）. "This hormone can lower blood pressure，as well as stress." Michael Murphy said.
    Of course，hugging is not the only way to comfort others.People sometimes give advice or just try to solve other people's problems directly.However，doing these things might make people feel like they're being criticized. "But hugging makes people feel like they are cared about and have someone who is there for them，" Murphy said. "But that doesn't make them feel being criticized."
    Scientists are still studying this effect.They want to know if it matters who the hug is from，or whether the person in question actually needs a hug.But Murphy said hugging is always a simple and helpful way to give support to someone you care about.
