请问句中的 wellness 与 health 有什么不同？
同意沅老师的解答。我再补充什么时间关于health和wellness有什么区别。
通常来讲，health 侧重有没疾病，wellness侧重对身体的保养，主动采取健康的生活方法和养生之道。请看海外网站对这两个词差别的讲解：
Wellness is an active lifestyle that incorporates several componentsthat affect health on a holistic level.
Wellness is an individual pursuit—we have self-responsibility for ourown choices, behaviors and lifestyles—but it is also significantly influencedby the physical, social and cultural environments in which we live.
Wellness is often confusedwith terms such as health, wellbeingand happiness. While there arecommon elements among them, wellness is distinguished by not referring to astatic state of being . Rather, wellness is associated with an active process of beingaware and making choices that lead toward an outcome of optimal holistic healthand wellbeing.
有的国家,如牙买加的卫生健康部英语为：Ministry of Health Wellness 美国纽约大学有一个Health Wellness Center. 这种使用方法，说明这两个词不可以完全替代。Health 强调治病，含可以打针输液，而wellness 指健康保养，包含采取主动改变生活方法，营养搭配，体育训练等办法。
因此，问题句中的a wellness book 主要指介绍怎么样维持健康的书，而不是强调在医学方面怎么样治疗。
