0:00:00.083,0:00:03.851
我哋好多人都鐘意[br]飲杯咖啡開始新嘅一日

0:00:03.875,0:00:06.893
又可能會飲杯酒嚟完結一日

0:00:06.917,0:00:09.143
又或者其他種類嘅酒

0:00:09.167,0:00:11.934
但原來呢兩種物質

0:00:11.958,0:00:16.768
酒精同咖啡因[br]都會對我哋嘅睡眠產生驚人嘅影響

0:00:16.792,0:00:19.331
〔與科學共枕〕

0:00:19.375,0:00:21.809
（沉思音樂）

0:00:21.833,0:00:24.101
由咖啡因開始講

0:00:24.125,0:00:26.309
咖啡因屬於一類藥物

0:00:26.333,0:00:29.684
我哋叫佢做精神興奮劑

0:00:29.708,0:00:33.101
而大家都知咖啡因會提神

0:00:33.125,0:00:35.143
會整醒佢哋

0:00:35.167,0:00:37.434
但其實起碼有兩樣

0:00:37.458,0:00:39.684
咖啡因嘅隱藏特點

0:00:39.708,0:00:42.434
係有啲人唔知嘅

0:00:42.458,0:00:47.059
第一種就係咖啡因嘅作用時間

0:00:47.083,0:00:49.059
咖啡因，對一般成人嚟講

0:00:49.083,0:00:51.559
會有我哋講嘅半衰期

0:00:51.583,0:00:53.851
大約係 5-6 個鐘左右

0:00:53.875,0:00:57.351
意思就係過咗大概 5-6 個鐘

0:00:57.375,0:01:00.601
仲有一半嘅咖啡因

0:01:00.625,0:01:03.643
仍然喺你嘅系統中循環

0:01:03.667,0:01:07.976
亦都代表佢仲有四份一嘅壽命

0:01:08.000,0:01:10.976
大槪 10-12 個鍾

0:01:11.000,0:01:11.968
換句話講

0:01:11.968,0:01:16.393
當你喺晏就兩點飲咗杯咖啡

0:01:16.417,0:01:20.143
咁有接近四份一嘅咖啡因

0:01:20.167,0:01:24.059
喺午夜嘅時候仲喺你大腦到

0:01:24.083,0:01:28.863
結果就令人更難以入睡

0:01:28.889,0:01:32.664
甚至難以成晚安睡

0:01:32.708,0:01:35.434
呢個就係咖啡因第一個特點

0:01:35.458,0:01:37.684
第二個咖啡因嘅問題係

0:01:37.708,0:01:41.351
佢可以改變你嘅睡眠質素

0:01:41.375,0:01:42.976
有啲人可能會同我講

0:01:43.000,0:01:47.333
我係嗰啲可以晚餐飲特濃咖啡

0:01:47.333,0:01:50.559
然後瞓得著又唔會醒嘅人嚟

0:01:50.583,0:01:53.059
但即使係真嘅

0:01:53.083,0:01:56.434
原來咖啡因係可以減低

0:01:56.458,0:01:59.893
我哋嘅深層非快速眼動睡眠嘅數量

0:01:59.917,0:02:03.059
第三、四期嘅非快速眼動睡眠係

0:02:03.083,0:02:06.018
算係一種恢復性深度睡眠

0:02:06.042,0:02:09.393
結果你第二朝起身

0:02:09.417,0:02:11.101
就唔會覺得精神

0:02:11.125,0:02:13.809
覺得瞓覺冇幫你差到電

0:02:13.833,0:02:15.434
但你唔記得你起過身

0:02:15.458,0:02:18.018
唔記得瞓唔著

0:02:18.042,0:02:20.226
所以你冇咗個連繫

0:02:20.250,0:02:23.018
但就算係咁，你之後就會發現自己

0:02:23.042,0:02:26.726
喺朝早飲兩杯咖啡提神

0:02:26.750,0:02:28.309
而唔係一杯

0:02:28.333,0:02:33.143
咖啡因講完啦，宜家到酒精

0:02:33.167,0:02:35.059
因為酒精可能係其中一種

0:02:35.083,0:02:39.143
比人誤解得最多嘅安眠工具

0:02:39.167,0:02:42.559
事實係，佢絕對唔係安眠工具

0:02:42.583,0:02:44.893
而且為你帶嚟睡眠問題

0:02:44.917,0:02:47.226
仲起碼有三種方法咁做

0:02:47.250,0:02:49.684
首先，酒精屬於一類藥物

0:02:49.708,0:02:52.184
我哋稱之為鎮靜劑

0:02:52.208,0:02:55.059
但鎮靜唔係睡眠

0:02:55.083,0:02:57.309
而研究教識咗我哋呢兩樣嘢

0:02:57.333,0:02:59.309
係幾唔同嘅

0:02:59.333,0:03:00.934
鎮靜嘅情況下

0:03:00.958,0:03:04.393
我哋就停止咗大腦細胞發射

0:03:04.417,0:03:07.809
特別係大腦皮層嘅

0:03:07.833,0:03:10.476
但咁唔係自然嘅睡眠

0:03:10.500,0:03:13.434
事實係喺深層非快速眼動睡眠期間

0:03:13.458,0:03:17.976
舉個例你個腦做到好出色嘅協調

0:03:18.000,0:03:20.684
可以將十萬個細胞

0:03:20.708,0:03:23.018
突然之間全部發射出嚟

0:03:23.042,0:03:24.476
然後佢哋就會全部靜哂

0:03:24.500,0:03:27.434
然後又一齊發射之後又靜哂

0:03:27.458,0:03:30.434
製造出呢啲深層非快速眼動睡眠

0:03:30.458,0:03:32.768
嘅強大腦電波

0:03:32.792,0:03:34.393
呢個就係第一種方法

0:03:34.417,0:03:36.809
點解酒精會帶嚟問題

0:03:36.833,0:03:40.268
我哋誤以為鎮靜係深層睡眠

0:03:40.292,0:03:42.518
酒精嘅第二個問題

0:03:42.542,0:03:45.643
係佢實際上會破壞你嘅睡眠

0:03:45.667,0:03:49.643
瞓覺嘅時候酒精可以觸發同激活

0:03:49.667,0:03:52.309
神經系統入面

0:03:52.333,0:03:53.893
一種我哋叫戰鬥或逃跑分支

0:03:53.917,0:03:58.208
咁就會成晚令你醒得更頻密

0:03:58.208,0:04:00.476
加上酒精仲會增加咗

0:04:00.500,0:04:04.184
大腦釋放嘅警覺化學物質

0:04:04.208,0:04:06.934
又再一次破壞你嘅睡眠

0:04:06.958,0:04:11.018
第三同最後一樣酒精同睡眠嘅問題

0:04:11.042,0:04:13.393
就係酒精實際上會阻擋咗

0:04:13.417,0:04:16.768
你嘅快速眼動睡眠同睡夢

0:04:16.792,0:04:19.476
而我哋之後嘅集數就會學到

0:04:19.500,0:04:21.633
REM 又或者叫快速眼動睡眠

0:04:21.633,0:04:24.559
同埋睡夢都會帶嚟一系列好處

0:04:24.583,0:04:26.726
好似情緒健康

0:04:26.750,0:04:30.101
精神健康，甚至係創造力

0:04:30.125,0:04:33.851
我唔係嚟教你點生活

0:04:33.875,0:04:35.851
我唔係要啲好循規蹈矩嘅生活

0:04:35.875,0:04:37.559
我只係個科學家

0:04:37.583,0:04:41.764
我想嘗試同做嘅係提供資料比大家

0:04:41.764,0:04:46.221
了解咖啡因同酒精與睡眠嘅關係

0:04:46.250,0:04:49.309
咁你就可以用知識做決定

0:04:49.333,0:04:52.059
當想將睡眠健康放第一嘅時候

0:04:52.083,0:04:54.833
你自己決定點生活先係最好
