Health psychology has acquired considerable experience and recognition abroad.
　　The program in health psychology of the Autonomous University of Barcelona （UAB） is a great opportunity for me to study at UAB with the research group \"Health， Sport and Lifestyle \"coordinated by Dr Lluis Capdevila.
　　In this book， I could not only study about healthy lifestyle and physical activity， but would also learn many aspects about Catalonia and Spain as ancient and rich historic countries in Europe： The tourism industry， which is highly developed； Spanish people love sports and have a great sense of humor. They are cheerful and enthusiastic； I was so excited that I received the offer from the Health， Sport and Lifestyle research group. If we combine the experience of traditional Chinese medicine treatment and the European empirical research， we shall be open to learn from each other. What a kind of interesting new findings will come to light！
　　In this book， the focus is about \"aroma efficacy in improving negative emotions， attention level， heart rate variability and in performing well in workplace and academic situations， through balancing the autonomic nervous system（ANS）. \"
　　The book has two general parts. The first one （theoretical part） is the background of aroma in the main context of traditional Chinese medicine. We will also take a look at the effects of aroma over physical and psychological symptomatology. The second part （empirical part） is dedicated to analyze the aroma efficacy for improving negative emotions， attention level and performance in the workplace and in academic situations.
