Jumping a few time zones causes problems with sleep and even digestion.
跳躍時(shí)區(qū)容易引起睡眠甚至消化的問(wèn)題。
But new research means we could be a step closer to preventing this voyager's vexation.
但是新的研究意味著我們可能距遠(yuǎn)離這一“飛行常客”帶來(lái)的煩惱再次近了一步。
The study centers on the hormone vasopressin, thought to have a role in maintaining our internal clock.
這項(xiàng)研究集中于被認(rèn)為在維持我們生物鐘扮演關(guān)鍵角色的抗利尿激素上。
Researchers genetically engineered mice that do not respond to vasopressin.
研究發(fā)現(xiàn)轉(zhuǎn)基因小白鼠對(duì)抗利尿激素沒(méi)有反應(yīng)。
Both engineered and normal rodents lived in a set cycle of light and dark for 2 weeks.
該研究將轉(zhuǎn)基因和正常小白鼠內(nèi)在一套光明和黑暗交替循環(huán)的設(shè)備生活2周時(shí)間。
Then the researchers changed the light cycle by eight hours.
然后研究人員以8小時(shí)為限改變光的周期。
And the vasopressin-insensitive mice recovered from their induced jet lag much more quickly than did their hormone-sensitive peers.
相比鄰居，對(duì)抗利尿激素不敏感的小白鼠從時(shí)差中恢復(fù)要快得多。
The work is in the journal Science.
該研究已經(jīng)在《科學(xué)》雜志上發(fā)表。
Jet lag may seem like a minor annoyance.
時(shí)差可能看起來(lái)像個(gè)小麻煩。
But for those who travel frequently or work unusual hours, it's a chronic problem that can increase the risk of hypertension and obesity.
但對(duì)于那些經(jīng)常出差或工作時(shí)間不規(guī)律人來(lái)說(shuō),這個(gè)長(zhǎng)期的問(wèn)題會(huì)增加高血壓和肥胖的風(fēng)險(xiǎn)。
You cannot simply knock out vasopressin signaling permanently—that would have negative effects on behavior and brain activity.
你不能簡(jiǎn)單的永久抑制抗利尿激素,這對(duì)行為和大腦活動(dòng)會(huì)造成負(fù)面影響。
But a drug that temporarily suppresses vasopressin to reduce jet lag may be a frequent flier's dream.
但一種暫時(shí)抑制抗利尿激素減少時(shí)差的藥物可能是飛行常客的夢(mèng)想。
