People who live near green spaces may be less likely than those surrounded by concrete to suffer a range of health problems, particularly depression and anxiety.

    Researchers found that among more than 300,000 Dutch adults and children, those living near more "green spaces" tended to have lower rates of 15 different health conditions.

    They found the link was especially strong when it came to depression and anxiety, suggesting that respite from stress and the hustle and bustle of urban life may be an important for reason for the benefits of green.

    Past studies have found that people who live in greener environments tend to report better subjective health.

    The findings build on evidence that green space has a positive effect on health and is more than just a luxury good.

    They gathered their information from the electronic medical records of 345,143 patients of about 200 general practitioners.

    They used an environmental database on land use to gauge the percentage of green space in the patients' neighborhoods.

    Overall, the study found, greater amounts of green space within one kilometer -- or 0.6 miles -- of people's homes was related to small reductions in the risks of health problems like heart disease, diabetes, chronic neck and back pain, asthma and migraine.

    The strongest connection was seen with depression and anxiety.

    Among people who lived in areas with 90 percent green space, for example, just over 2 percent had been diagnosed with depression, compared with just over 3 percent of those living in areas with 10 percent green space.

    Greener environs could potentially have positive affects on health through a number of pathways, including better air quality and more opportunities for exercise.

    But, the researchers added, the link with depression and anxiety suggests that stress reduction and a lesser likelihood of "attention fatigue" could be especially important. The study also found that the relationship between green space and health was particularly strong among children and lower-income groups, which, the researchers speculate, could be because they tend to spend much of their time close to home.

    居住地附近绿树环绕的人们比那些被钢筋水泥包裹的人们患病几率要少，尤其是抑郁症和焦虑。

    研究者对30多万名丹麦的儿童和成人做了研究，居住地周围有"绿地"的人们的健康状况高于其他人15个百分点。

    他们发现这之间的联系非常密切，抑郁和焦虑时，建议暂时离开紧张、忙乱、喧闹的都市生活中，绿色可能有助于缓解这种情况。

    以往的研究也发现，在绿色的环境中居住的人们主观上感觉更健康一些。

    这一结论的依据是绿色对健康有积极的影响，并不仅仅是一个奢侈的享受。

    他们的结论来源于对200名医生的接诊的345,143名患者的电子病历进行分析后得出的。

    他们利用环境数据来测算病人周围的绿地面积。

    总的说来，研究发现，居住地周围1千米或0.6英里范围内的绿地能够减少患病的危险，如心脏病、糖尿病、慢性颈椎和背部疾病、哮喘和偏头疼等。

    与抑郁症和焦虑疾病的关系最为明显。

    举例来说，居住地周围90%都是绿地，只有2%的人被诊断患有抑郁症，而周围环境只有10%的绿地，患抑郁症的人数超过3%.

    绿色环境可以从以下几个方面给健康带来积极影响，包括更好的空气质量和更多的锻炼机会。

    但是研究者还说，抑郁和焦虑的发病与压力过大和"心力憔悴"也有很大的关系。研究还发现，绿地和健康的关系对于儿童和低收入人群更为密切，研究者推测 可能是因为她们呆在家中的时间更多的缘故。
