介绍： Regular exercise’best for mental health’
规律运动有益于心理健康
Regular physical activity lasting 45 minutes three to five times a week can reduce poor mental health-but doing more than that is not always beneficial,a large US study suggests.A total of 1.2 million people reported their activity levels for a month and rated their mental wellbeing.People who exercised had 1.5 fewer"bad days"a month than non-exercisers,the study found.Team sports,cycling and aerobics had the greatest positive impact.All types of activity were found to improve mental health no matter people’s age or gender,including doing the housework and looking after the children.
美国一项大型研究表明，每周进行3到5次持续45分钟的常规体力活动可以减少心理健康不佳的状况——但过多的运动却并不总是有益的。共有120万人报告了他们在一个月内的运动水平并评估了他们的心理健康状况。研究发现，锻炼的人每月的“糟糕日子”比不锻炼者少1.5天。团体运动，骑自行车和健美操的积极影响最显著。无论人们的年龄或性别如何，所有类型的活动都被证实可以改善心理健康，包括做家务和照顾孩子。
The study,published in The Lancet Psychiatry Journal,is the largest of its kind to date but it cannot confirm that physical activity is the cause of improved mental health.Previous research into the effects of exercise on mental health have thrown up mixed results,and some studies suggest that lack of activity could lead to poor mental health as well as being a symptom of it.Exercise is already known to reduce the risk of heart disease,stroke and diabetes.
该研究发表在《柳叶刀精神病学》杂志上，是迄今为止规模最大的研究，但它无法证实身体活动是改善心理健康的原因。之前的关于运动对心理健康影响的研究得到不同的结果，一些研究表明，缺乏运动可能导致心理健康状况不佳并且成为心理健康不佳的症状。运动可以降低患心脏病，中风和糖尿病的风险已被认知。
Adults taking part in the study said they experienced on average 3.4 days of poor mental health each month.For those who were physically active,this reduced to only two days.Among people who had been diagnosed previously with depression,exercise appeared to have a larger effect,resulting in seven days of poor mental health a month compared with nearly 11 days for those who did no exercise.How often and for how long people were active was also important.Being active for 30 to 60 minutes every second day came out as the optimal routine.
参加这项研究的成年人表示，他们每个月平均心理健康状况不佳的天数为3.4天。对于身体活跃的人来说，这减少到仅2天。在先前被诊断患有抑郁症的人中，运动似乎有更大的影响，导致每月有7天心理健康状况不佳，而没有运动的人则接近11天。人们活跃的频率和持续时间也很重要。每隔一天活跃度达到30到60分钟为最佳。
But there could be such a thing as doing too much exercise,the study concluded.Dr Adam Chekroud,study author and assistant professor of psychiatry at Yale University,said:"Previously,people have believed that the more exercise you do,the better your mental health,but our study suggests that this is not the case."Doing exercise more than 23 times a month,or exercising for longer than 90-minute sessions is associated with worse mental health."He said the positive impact of team sports suggested that social sports activities could reduce isolation and be good for resilience,while also reducing depression.
但是研究得出的结论是，过多的运动可能适得其反。耶鲁大学研究作者兼精神病学助理教授Adam Chekroud博士说：“以前，人们相信你做的运动越多，你的心理健康就越好，但我们的研究表明情况并非如此。”“每月锻炼超过23次，或者锻炼时间超过90分钟，会导致心理健康状况恶化。”他说，团队运动的积极影响表明，社交型体育活动可以减少孤立感，有利于恢复力，同时也可以减少抑郁症。
