When you're under stress，exercise can be the first habit to go .Though moving your body is one of the best ways to fight against stress，Melanie Caine，a yoga（瑜伽） teacher，advises not doing much exercise a day. "A little goes a long way，" she says.
   Some people will probably turn their necks when they work，read or even walk for a long time.However，Caines also advises people to have a rest for shoulder（肩膀）moves.To do this，start by taking in air deeply，raising the shoulders towards the ears，exhaling（呼氣） and moving the shoulders back and down.Caines advises doing this without any strong movements-and only if we feel good and there's no ache.
   Another activity that people often don't make time for is intentional breathing（有意識的呼吸）."Breathing enough oxygen（氧氣） can keep us awake，but we don't often use this quite useful tool，"says Caines. "At any time during the day，try taking a breath in through the nose，opening the mouth and breathing.And then it'll start to help yourself relax."
