壓力為什么能讓你變胖?

Have you ever had a stressful day? Many people do in the course of their daily lives. And on these high-pressure days, they might find themselves reaching for a sugary snack. Perhaps this is part of their daily routine. Or perhaps on this particular day, their self-control is a bit low and they feel compelled to take a sugar hit.

你有過壓力很大的一天嗎?許多人在日常生活中或許都有這樣的時候。這樣的日子里,他們可能會想吃甜食。也許這是他們平常就是喜歡吃甜食;亦或者也許他們的自控力因為壓力降低了,覺得有必要吃些甜食緩解一下。

Stress is natural. That feeling of strain or pressure is a biological response, and under the right circumstances can be a great source of motivation. However, too much stress, especially chronic stress, has been linked to sleep disruption, a higher likelihood of a stroke, heart-attack, ulcer or depression, among other things. But why should stress make a person comfort eat?

壓力是自然反應。這種緊張或壓迫感是一種生物反應,在適當的環境下可以成為動力的一大來源。然而,過多的壓力尤其是慢性壓力,會致使睡眠中斷、中風、心臟病發作、潰瘍或抑郁癥等疾病的高發。但是為什么壓力會讓人舒服地吃東西呢?

Dr Giles Yeo, a member of the BBC's Trust Me, I'm a Doctor team, got together with scientists from Leeds University to conduct an experiment into the effect of stress on blood sugar. Dr Yeo was subjected to a stress test. In the first stage, he was forced to answer mathematical questions rapidly. In the second, he had to immerse his hand in a bath of ice-cold water for a period of time.

英國廣播公司Trust Me, I’m a Doctor team欄目的成員之一楊吉爾博士和利茲大學的科學家們一起進行了一項關于壓力對血糖影響的實驗,并且楊博士親身參與了實驗。在第一階段,他被要求快速地回答數學問題。第二階段,他要把手浸入冰水中一段時間。

Before and after these tests, the Leeds scientists would measure Dr Yeo's blood sugar levels. These are the levels which rise when we eat as our body takes in the energy of the food. In a healthy person, these levels quickly return to normal. However, when Dr Yeo was being deliberately subjected to stress, his blood sugar took six times longer to drop than on a stress-free day.

利茲大學的科學家們測量了楊博士在參加實驗之前和之后的血糖水平。我們進食時,身體會吸收食物的能量,血糖水平就會上升。在健康人體內,這些水平會很快恢復正常。然而,當楊博士被故意施加壓力時,他的血糖恢復時間是正常的六倍。

When we become stressed, our bodies enter 'fight or flight' mode. Because our body believes it's under attack, it releases glucose into the blood to provide energy for muscles. However, if we don't use that energy, our body then releases insulin to make the blood sugar levels drop. This drop causes a hunger response: you want to eat. And what you particularly crave is sugary food, which rapidly replenishes the energy you have lost. If this happens repeatedly, over a long enough period, these high-calorie foods can lead to obesity.

當我們感到壓力時,我們的身體進入“戰斗或逃跑”模式。因為身體認為自己受到了攻擊,它會向血液中釋放葡萄糖,為肌肉提供能量。然而,如果我們不使用這些能量,我們的身體就會釋放胰島素,這時血糖水平就會下降。這種血糖下降會引起饑餓:想吃東西。而且這時特別想吃甜食,因為它能迅速補充你失去的能量。如果長時間重復這種情況,這些高熱量的食物就會導致肥胖。

So what can we do to combat the stress? In an article for the BBC, Dr Michael Mosley recommends 'stress-busting' techniques, like exercise, gardening, mindfulness or another activities that you enjoy. But his strongest recommendation is trying to get a good night's sleep. A recent study carried out by researchers at King's College, London found that if you deprived people of sleep, they would consume, on average, an extra 385kcal per day, which is equivalent to the calories in a large muffin. So, try sleeping to decrease stress, and as a result make it easier to keep yourself a little trimmer.

那么我們能做些什么來對抗壓力呢?在為英國廣播公司(BBC)撰寫的一篇文章中,MichaelMosley博士推薦了一些“減壓”技巧,比如鍛煉、做園藝、正念或進行其它你喜歡的活動。但他最強烈的建議是晚上睡個好覺。倫敦國王學院的研究人員最近進行的一項研究發現,如果減少睡眠時間,人體平均每天會多消耗385千卡,這相當于一個大松餅所含的熱量。所以,試著通過睡覺來解壓,這還能讓你更容易保持苗條。
