痛風(fēng)患者：除了吃藥,，要“管住嘴,、多喝水,、邁開腿”,。

痛風(fēng)或血尿酸偏高的人,，確實(shí)應(yīng)該適當(dāng)運(yùn)動(dòng)，2014年7月發(fā)表在《關(guān)節(jié)疾病年鑒Annals of the Rheumatic Diseases》有一篇臺(tái)灣的研究結(jié)果：

Physical activity is a valuable alternative to pharmacotherapy in its ability to reduce the increases in mortality risks from high sUA. By being fully active, exercise can extend life span by 4–6?years, a level greater than the 1–4?years of life-shortening effect from high sUA.

體育活動(dòng)能夠有效降低高尿酸血癥患者的死亡率,，一般來講,，與正常人相比，高尿酸血癥病人的壽命要少1-4年,，而經(jīng)常運(yùn)動(dòng)的高尿酸血癥患者可以延長壽命4-6年,。

除了長壽，經(jīng)常適當(dāng)運(yùn)動(dòng),，可以降低痛風(fēng)病人的發(fā)病率,。于是，市面上有種說法：

汗液含有尿酸,，所以運(yùn)動(dòng)出汗可以達(dá)到排酸降酸的目的,，因此痛風(fēng)病人得經(jīng)常蒸桑拿。

蒸桑拿排尿酸嗎,？

2004年,，日本兵庫醫(yī)科大學(xué)（ Hyogo College of Medicine）做過一個(gè)小實(shí)驗(yàn),，研究喝啤酒,、蒸桑拿、喝完啤酒再蒸桑拿三種情況體內(nèi)嘌呤和尿酸濃度以及尿酸排泄的情況,。

結(jié)果發(fā)現(xiàn)：

“Afterthe sauna alone, they found that the concentration of purines in thebloodstream had decreased, with more being converted to uric acid. However, theamount of uric acid excreted from the body was also lowered.”

翻譯為：桑拿后,，人體血液中嘌呤含量降低，尿酸濃度升高,，同時(shí),，還發(fā)現(xiàn)體內(nèi)尿酸排泄的數(shù)量也降低了。

所以說,，蒸桑拿不能夠達(dá)到降酸的目的,，那么，尿酸能不能通過汗液排泄呢,？

尿酸是否可以通過汗液排泄,？

2002年臺(tái)灣一個(gè)研發(fā)團(tuán)隊(duì)在《The Chinese Journal of Physiology》上發(fā)表了一篇文章《人體汗液的尿酸和尿素Uric acid and urea in human sweat.》，他們發(fā)現(xiàn)：

The results show that the concentration of uric acid in the sweat is 24.5 μmol/L, which is only 6.3% of that in serum....The results indicate that sweat uric acid concentration is quite minimal, and the estimated total uric acid excretion per day in normal physiological range is insignificant. However, the level of sweat urea was found at a much higher concentration than the serum level. ...

炎熱環(huán)境劇烈運(yùn)動(dòng)一小時(shí)后,，汗水尿酸的濃度為24.5微摩爾/升,，只占血清尿酸含量的6.3％,。...汗水中的尿酸濃度很低，在人體尿酸總排泄量占到微不足道的分量,。

沒概念,？就算你出5升汗，夠多了吧,，也就排泄5*24.5=122.4μmol的尿酸,，咱們每天通過尿液能排泄多少尿酸？

每天尿液正常排泄尿酸1200～4500μmol,，是汗液排尿酸的幾十倍,！你得每天排50升汗，才能達(dá)到這水平....

痛風(fēng)病人運(yùn)動(dòng)后得補(bǔ)水,！

2010年,，臺(tái)灣同一團(tuán)隊(duì)又發(fā)表了一篇文章《劇烈運(yùn)動(dòng)出汗對尿液排泄尿酸的影響Effects of profuse sweating induced by exercise on urinary uric acid excretion in a hot environment.》，發(fā)現(xiàn)：

The results show that the concentration of uric acid in the sweat is 24.5 μmol/L, which is only 6.3% of that in serum....The results indicate that sweat uric acid concentration is quite minimal, and the estimated total uric acid excretion per day in normal physiological range is insignificant.

2010年，臺(tái)灣同一團(tuán)隊(duì)又發(fā)表了一篇文章《劇烈運(yùn)動(dòng)出汗對尿液排泄尿酸的影響Effects of profuse sweating induced by exercise on urinary uric acid excretion in a hot environment.》,，發(fā)現(xiàn)：

It is concluded profuse sweating exercise results in a decrease of urinary uric acid excretion amounts and leads to increased serum uric acid after the exercise. We suggest that persons who take vigorous exercise or are exposed to hot environments need drinking enough fluids to prevent dehydration and maintain adequate urinary output. People with profuse sweat after rigorous exercise are recommended taking sports drinks containing abundant sodium in order to decrease serum uric acid.

劇烈運(yùn)動(dòng)大量出汗后,，尿液尿酸排泄降低，導(dǎo)致血尿酸降低,，建議劇烈運(yùn)動(dòng)的痛風(fēng)病人喝足夠的水,，以防止脫水，并保持充足的尿量,。如果出汗很多,，建議喝含納的運(yùn)動(dòng)飲料。

結(jié)論：

1）通過蒸桑拿或者劇烈運(yùn)動(dòng)出汗都達(dá)不到降酸的目的,；

2）痛風(fēng)病人應(yīng)該適當(dāng)運(yùn)動(dòng),，但是不鼓勵(lì)劇烈運(yùn)動(dòng),；
