Tai chi, a traditional, slow-moving form of Chinese physical exercise, is known to increase flexibility and improve balance. New research has been conducted to determine whether tai chi has an influence on lowering blood pressure in people with prehypertension (高血压前期). 

In the study, Chinese scientists put 342 adults with prehypertension into two groups. The average age of people taking part in the study was 49. About half the participants (参与者) took part in aerobic exercise, including jogging, climbing stairs and cycling. The other half was trained to practice tai chi. Both groups got hour-long exercises four times a week. 

Nearly 22% of the people who practiced tai chi saw their blood pressure fall to be normal, compared with nearly 16% of people in the aerobic exercise group. And fewer patients in the tai chi group went on to develop high blood pressure than patients in the aerobic exercise group. 

So what is it about tai chi that helps lower blood pressure? "The practice tends to get more of a response from the parasympathetic (副交感的) nervous system, which is the network of nerves that relaxes your body after periods of stress or danger, " says Ruth Taylor-Piliae, a professor at the University of Arizona's College of Nursing.

"I think the beauty of tai chi is that you don't have to have a special gym membership, you don't have to have special clothing, " Taylor-Piliae says. "Once you learn tai chi, you can do it anytime and anyplace. And it does provide a calming and relaxing effect. "

Evidence suggests it can also help protect against cognitive fall and even improve memory. But you have to practice it continually to get the most benefit. 

Dorothea Dix was born in 1802 in Massachusetts. When she was 12 years old, she left her unhappy home to live with her grandmother in Boston. There Dorothea went to school and was so quick at her lessons that two years later she went back to Worcester, Massachusetts and taught in a school for little children. She was only fourteen and rather small for her age. Anyway, she proved herself a good teacher, and the children loved her and respected her. In 1821, she opened a school for girls in Boston. 

Gradually, her health broke down, and she began to think that she could never work any more, but after a long rest in England, she came back to America and did something far greater than teaching. She went through the whole country where she first observed the inhumane treatment of the mentally ill. During Dorothea's traveling for nearly two years throughout the state, and meeting similar conditions, she always spoke kindly to the ill-treated, but she spokewrathfully to the men who ill-treated them. In January 1843, she submitted to the Massachusetts legislature (立法机关) a detailed report of her fully documented findings.

In the next 40 years Dorothea inspired legislators in 15 US states and in Canada to establish state hospitals for the mentally ill. Her continuous efforts directly affected the building of 32 institutions in the United States. When the Civil War broke out, she went straight to Washington and offered to nurse the soldiers without pay. She hired houses to keep supplies in and bought an ambulance. She gave her time, strength and money to her country. 

Dorothea Dix has been called the most useful woman of America. She is an, American educator, social reformer and humanitarian whose devotion to the welfare of the mentally ill led to widespread reforms in the United States and abroad.
