Yoga beats running in avoiding depression

Chinese University study finds Hongkongers who do mind-body exercises are at much lower risk of developing a mood disorder

Hongkongers who do no exercise are 3.7 times more likely to develop a mood disorder than those who exercise regularly, a study has found.

And yoga and tai chi are more effective than cardio exercises such as running in reducing that risk, according to the study by Chinese University.

"When you exercise, a kind of protein [known as a neurotrophic factor] is generated in your brain that can lower the risk of mood disorder," said Professor Linda Lam Chiu-wa, chairwoman of the university's psychiatry department.

The university surveyed 2,744 people between May and July, using the widely recognised Kessler Scale-6 to determine whether they suffered from a mood disorder, such as depression or anxiety.

The scale consists of a number of questions about how often interviewees feel nervous or depressed.

The survey found that 73.6 per cent of respondents showed a low risk of developing mood disorder and 20.7 per cent showed a medium risk. Another 5.6 per cent showed a high risk and were recommended to see a doctor as soon as possible.

The figures are similar to results from previous surveys carried out in the United States and Hong Kong, suggesting that the situation in the city has not got worse.

The study found that those who do no exercise at all were 3.7 times more likely to develop a mood disorder compared to those who exercised for 30 minutes twice a week.

Those who exercise but do not do so regularly were 1.8 times more likely to develop a disorder than those who regularly exercise.

"When you exercise, especially when you do it with your friends, the social interaction boosts your self-esteem. It can lower cortisol [a stress-related hormone]," Lam said.

When it comes to which kind of exercise to choose, the study found cardio exercises were not as effective as mind-body exercises in reducing the risk of developing mood disorders.

Those who did cardio exercises regularly were three times less likely to develop a disorder, but those who did mind-body exercises were 3.4 times less likely to develop one.

"When you do mind-body exercises, you need to match your breathing to the way you move, and you need to stay focused. That really helps you in lowering your stress," Lam said.

Alex Lai, 54, was diagnosed as suffering from anxiety disorder 10 years ago.

"I was always anxious about everything. I suffered from insomnia and felt there was something pushing against me on my chest.

"I took anti-depressants at that time but the effect did not last long," Lai said.

Lai took the advice of his doctor and started jogging twice a week, 20 minutes each time.

"I feel such a sense of relief every time I go jogging because there is nothing troubling me when I am exercising," he said.

Most people don’t know that they can pump more blood to all their brain cells and other organ cells, if they trick their brains a little bit. This is how traditional taichi (much slower than the modern taichi) elevates your heart rate to increase brain size and heal everything. Now, we begin to understand how imperfect our capillaries(sphincters/pericytes) are even from young age.
Doesn't help with the stress when people are too busy looking at their phones and worrying about what their friends are buying and where they are eating...instead, how about taking a step outside for a walk or go to the gym, will make you feel better about yourself too.
Superdx, I'm sure even in this environment, going out for a run is still better than sitting on your bottom all day; there's always filtered air in the gym, got to make the best out of the situation I guess.
Overall, Hong Kong/Chinese people generally don't do much exercise, they'd rather believe in eating supplements to lose weight than working out...don't understand the rationale behind that as someone who runs everyday.
Too bad exercising in an API of 80 will probably mean lung cancer. Choose between that and a trip to the shrink. Probably the latter is preferable since chemotherapy sucks.
