Cryotherapy is done by exposing your body to extreme cold for medical benefits.

超低温冷疗是一种通过将身体置于极冷的环境中，以达到治疗目的物理康复方法。

The popular whole-body cryotherapy method has you stand in a chamber that covers all parts of your body except your head. The air in the chamber goes down to temperatures as low as negative 200°F to 300°F for up to 5 minutes.

一般来说，全身超低温冷疗需要你站立在一个舱体中，该舱体将会覆盖头部以下的所有部位，舱体中的温度将会下降到-200°F至-300°F长达5分钟。（包含预冷时间，体验时间一般在3分钟以内）

Cryotherapy has become popular because of its ability to treat painful and chronic conditions like migraine and rheumatoid arthritis. And it’s also been thought to be a possible weight loss treatment.

超低温冷疗在治疗疼痛和慢性疾病方面已经取得了显著的效果，因此变得越来越流行。现在，它也被认为是针对减肥可能有效的方法。

Purported benefits of cryotherapy for weight loss

The theory behind cryotherapy is that it freezes fat cells throughout the body and kills them off. This causes them to be filtered out of the body by your liver and permanently removed from areas of fat tissue.

超低温冷疗减肥是基于低温能够冷冻整个人体的脂肪细胞并“杀死”它们的理论，这会导致脂肪被肝脏过滤掉，并从脂肪组织区域永久清除。

A 2013 study in the Journal of Clinical Investigation found that daily exposure to cold temperatures (62.5°F or 17°C) for 2 hours a day over 6 weeks reduced total body fat by about 2 percent.

2013年发表于的一项研究表明，每天暴露于寒冷的温度下（65℉或者17℃）2小时并持续6周，会让身体总脂肪降低约2%。

This is because a substance in your body called brown adipose tissue (BAT) burns fat to help make energy when your body is exposed to extreme cold.

这是因为当身体暴露于极冷的环境中时，体内的一种被称为棕色脂肪组织（BAT）的物质会燃烧脂肪，以帮助产生能量。

这个实验有效验证了“低温能够燃脂”的理论。

A 2014 in Diabetes exposed participants to increasingly cold temperatures and then increasingly warmer temperatures every night for 4 months. The study started at 75°F (23.9°C) down to 66.2°F (19°C) and back up to 81°F (27.2°C) by the end of the 4-month period.

2014年，一项发表于的实验研究，让参与者每晚暴露在越来越冷的温度下，然后将温度逐渐升高{温度一开始设定为75°F(23.9°C)，然后下降到66.2°F(19°C)，再回到81F (27.2°C)}，持续4个月。

The researchers found that exposure to progressively cooler then warmer temperature can make your BAT more responsive to these temperature changes and help your body become better at processing glucose.

研究人员发现，暴露于逐渐降低然后升高的温度的环境下，可以使人体的棕色脂肪对这些温度变化更敏感，并帮助身体更好地处理葡萄糖。

This isn’t necessarily linked to weight loss. But increased sugar metabolism can help you lose weight over time by helping your body better digest sugars that can otherwise turn into body fat.

该研究似乎与减肥无关。但实际上，糖代谢增加可以帮助身体更好地消化糖，从而逐步减肥，否则糖会转化为体内脂肪。

Other research also supports the idea that cryotherapy works best when it’s combined with other strategies for weight loss — like exercise.

其他研究也支持这样一种观点，即超低温冷疗与其他减肥方法（例如运动）结合使用时，减肥效果最佳。

A 2014 study in Oxidative Medicine and Cellular Longevity followed 16 kayakers on the Polish National Team who did whole-body cryotherapy at −184°F (−120°C) down to −229°F (−145°C) for about 3 minutes a day for 10 days.

一项发表在的研究，跟随观察了16名波兰国家队皮划艇运动员持续十天每天进行3分钟超低温冷疗，温度从-184°F（-120℃）下至-229°F（-145℃）。

Researchers found that cryotherapy helped the body recover more quickly from exercise and reduce the effects of reactive oxygen species (ROS) that can cause inflammation and weight gain over time.

研究人员发现，超低温冷疗能够帮助身体从运动中更快恢复，并减少活性氧（ROS）的影响（活性氧会随着时间的流逝引起炎症和体重增加）。

This means that cryotherapy can allow you to exercise more often due to a faster recovery time and experience fewer negative effects of stress and weight gain.

这意味着，由于恢复时间更快，超低温冷疗可以使人体提高运动频率，并减少压力和体重增加带来的负面影响。

And here are some other recent highlights from research on cryotherapy for weight loss:A 2018 study in the Journal of Obesity found that long-term cryotherapy activates a process in the body called cold-induced thermogenesis. This led to an overall loss of body mass particularly around the waist by an average of 3 percent.

以下是有关超低温冷疗减肥的最新研究成果：一项2018在< Journal of Obesity >发表的研究发现，长期持续进行超低温冷疗，能够激活体内被称为“冷诱导的热发生”的机制，这会导致体重的整体下降，腰围方面平均下降了3%。
