The first tip is regularity.

00:23
Go to bed at the same time and wake up at the same time.

and it will actually anchor your sleep

μ΄λŠ” κ³ μ •λœ 수면 νŒ¨ν„΄μ„ λ§Œλ“€λ©°

and improve both the quantity and the quality,
13
31296
2991
수면의 μ–‘κ³Ό 질 λͺ¨λ‘λ₯Ό κ°œμ„ ν•©λ‹ˆλ‹€.
00:34
no matter whether it's the weekday or the weekend

3128
평일이든 주말이든 상관없고,
00:37
or even if you've had a bad night of sleep.

37463
2119
심지어 μ „λ‚  λ°€μž μ„ μ„€μ³€λ”λΌλ„μš”.
00:39
And the reason is because deep within your brain,
16

3041
μ΄λŠ” μ—¬λŸ¬λΆ„μ˜ λ‡Œ κΉŠμˆ™μ΄
00:42

00:56
Many of us use an alarm to wake up

2374
우리 λŒ€λΆ€λΆ„μ€ μ•„μΉ¨ 기상에 μ•ŒλžŒμ„ μ‚¬μš©ν•˜μ§€λ§Œ

01:02
and that's something that can be helpful.
23

1975
그런데 그게 도움이 될 수 μžˆμŠ΅λ‹ˆλ‹€.
01:04
The next tip is temperature.
24
64196
2743
λ‹€μŒ νŒμ€ μ˜¨λ„μž…λ‹ˆλ‹€.
01:06
Keep it cool.

01:08
It turns out that your brain and your body

need to drop their core temperature by about one degree Celsius

70675
4971
μ²΄μ˜¨μ„ 섭씨 1도 정도, 즉 화씨 2~3도 정도 λ‚΄λ €μ•Ό
01:15
or around two to three degrees Fahrenheit
28

01:18
in order to initiate sleep and then to stay asleep.

01:29

89707
1741
λ”°λΌμ„œ κ°€μž₯ ꢌμž₯λ˜λŠ” μ˜¨λ„λŠ”
01:31
is to aim for a bedroom temperature

01:34
of around about 65 degrees Fahrenheit,
34

or a little over 18 degrees Celsius.

97316

It sounds cold but cold it must be.

μΆ₯게 λ“€λ¦¬μ§€λ§Œ μˆ˜λ©΄μ—λŠ” μΆ”μœ„κ°€ ν•„μš”ν•©λ‹ˆλ‹€.
01:43
The next tip is darkness.
37
103267
2494
λ‹€μŒ νŒμ€ μ–΄λ‘ μž…λ‹ˆλ‹€.
01:46
We are a dark-deprived society

ν•˜μ§€λ§Œ μš°λ¦¬λŠ” 특히 저녁에 어둠이 ν•„μš”ν•©λ‹ˆλ‹€.
01:49
and, in fact, we need darkness specifically in the evening
39
109004
3900
01:52
to trigger the release of a hormone called melatonin.
40
112928
4064
λ©œλΌν† λ‹Œμ΄λΌλŠ” 호λ₯΄λͺ¬μ˜ λΆ„λΉ„λ₯Ό μ΄‰μ§„ν•˜κΈ° μœ„ν•΄μ„œμ£ .

01:57
And melatonin helps regulate the healthy timing of our sleep.
41
117016
5392
02:02
In the last hour before bed,
42
122432
1967
μ·¨μΉ¨ ν•œ μ‹œκ°„ 전에
02:04
try to stay away from all of those computer screens
43
124423
3656

02:08
and tablets and phones.
44
128103
2065
02:10
Dim down half the lights in your house.
45
130192
3249
집 μ‘°λͺ…을 절반 정도 μ–΄λ‘‘κ²Œ ν•˜μ„Έμš”.
02:13
You'd actually be quite surprised
46
133465
1990
그러면 정말 λ†€λžκ²Œλ„
02:15
at how sleepy that can make you feel.
47
135479
2808
μ‰½κ²Œ μž μ— λ“ λ‹€λŠ” λŠλ‚Œμ΄ λ“€ κ²λ‹ˆλ‹€.
02:18
If you'd like, you can wear an eye mask
48
138311
2517
μ›ν•˜μ‹œλ©΄ μ•ˆλŒ€λ₯Ό μ°©μš©ν•˜μ‹œκ±°λ‚˜
02:20
or you can have blackout shades
49
140852
2150
암막 μ»€νŠΌμ„ μ‚¬μš©ν•˜μ…”λ„ λ©λ‹ˆλ‹€.
02:23
and that will help best regulate
50
143026
2334
그러면 μ€‘μš”ν•œ 수면 호λ₯΄λͺ¬μΈ λ©œλΌν† λ‹Œμ΄ 잘 μ‘°μ ˆλ˜λ„λ‘ 도와쀄 κ²ƒμž…λ‹ˆλ‹€.
02:25
that critical sleep hormone of melatonin.
51
145384
2957
02:28
The next tip is walk it out.
52
148365
2579
λ‹€μŒ νŒμ€ μΉ¨λŒ€ λ°–μœΌλ‘œ λ‚˜κ°€λŠ” κ²ƒμž…λ‹ˆλ‹€.
02:30
Don't stay in bed awake for long periods of time.
53
150968
3990
μΉ¨λŒ€μ—μ„œ κΉ¨μ–΄μžˆλŠ” μ±„λ‘œ 였래 λˆ„μ›Œμžˆμ§€ λ§ˆμ„Έμš”.
02:35
And the general rule of thumb
54
155260
1748
일반적으둜
02:37
is if you've been trying to fall asleep
55
157032
2031
25λΆ„ 정도 μž λ“€λ €κ³  λ…Έλ ₯ν–ˆκ±°λ‚˜
02:39
and it's been 25 minutes or so,
56
159087
2461
02:41
or you've woken up and you can't get back to sleep
57
161572
2896
μž μ—μ„œ κΉ¬ λ’€ 25뢄이 μ§€λ‚˜λ„λ‘ λ‹€μ‹œ 잠이 듀지 μ•ŠμœΌλ©΄
02:44
after 25 minutes,
58
164492
1521
02:46
the recommendation is to get out of bed
59
166037
2844
μΉ¨λŒ€ λ°–μœΌλ‘œ λ‚˜κ°€μ„œ
02:48
and go and do something different.
60
168905
1978
λ‹€λ₯Έ 일을 ν•˜λŠ” 것을 μΆ”μ²œν•©λ‹ˆλ‹€.
02:50
And the reason is because your brain
61
170907
2286
μ΄λŠ” μ—¬λŸ¬λΆ„μ˜ λ‡Œκ°€
02:53
is an incredibly associative device.
62
173217
2825
맀우 μ—°κ΄€μ„± μžˆλŠ” μž₯치이기 λ•Œλ¬Έμž…λ‹ˆλ‹€.
02:56
The brain has learned the association
63
176066
2698
우리의 λ‡ŒλŠ” μΉ¨λŒ€κ°€ λΆˆλ©΄μ¦μ„ μœ λ°œν•œλ‹€λŠ” 연관성을 μŠ΅λ“ν•˜κΈ° λ•Œλ¬Έμ—
02:58
that the bed is this trigger of wakefulness,
64
178788
3232
μš°λ¦¬λŠ” κ·Έ 연관성을 κΉ¨λœ¨λ €μ•Ό ν•©λ‹ˆλ‹€.
03:02
and we need to break that association.
65
182044
2603
03:04
And by getting out of bed, you can go and do something else.
66
184671
3436
그리고 μΉ¨λŒ€ λ°–μœΌλ‘œ λ‚˜κ°μœΌλ‘œμ¨ λ‹€λ₯Έ 일을 ν•  μˆ˜κ°€ μžˆμŠ΅λ‹ˆλ‹€.
03:08
Only return to bed when you're sleepy.
67
188131
3143
정말 잠이 올 λ•Œλ§Œ μΉ¨λŒ€λ‘œ λŒμ•„κ°€μ„Έμš”.
03:11
And in that way, gradually,
68
191298
1651
그럼 μ—¬λŸ¬λΆ„μ˜ λ‡ŒλŠ” 점차적으둜
03:12
your brain will relearn the association
69
192973
3261
연관성을 λ‹€μ‹œ μŠ΅λ“ν•  κ²ƒμž…λ‹ˆλ‹€.
03:16
that your bed is this place of sound and consistent sleep.
70
196258
4887
μΉ¨λŒ€κ°€ 깊고 μΌμ •ν•œ μˆ˜λ©΄μ„ μ·¨ν•˜λŠ” μž₯μ†ŒλΌλŠ” κ²ƒμ„μš”.
03:21
The fifth tip is something that we've actually
71
201169
2655
λ‹€μ„― 번째 νŒμ€
이 μ‹œλ¦¬μ¦ˆμ—μ„œ 이미 μžμ„Ένžˆ μ–ΈκΈ‰ν•œ κ²ƒμΈλ°μš”.
03:23
already spoken about in detail in this series,
72
203848
3396
03:27
which is the impact of alcohol and caffeine.
73
207268
3201
λ°”λ‘œ μ•Œμ½”μ˜¬κ³Ό 카페인의 영ν–₯μž…λ‹ˆλ‹€.
03:30
So, a good rule of thumb here is to try to stay away
74
210493
2843
λ”°λΌμ„œ κ²½ν—˜μœΌλ‘œ 보면,
μ˜€ν›„μ™€ 저녁에 μΉ΄νŽ˜μΈμ„ μ΅œλŒ€ν•œ λ©€λ¦¬ν•˜λŠ” 것이 μ’‹μŠ΅λ‹ˆλ‹€.
03:33
from caffeine in the afternoon and in the evening
75
213360
2997
03:36
and certainly try not to go to bed too tipsy.
76
216381
3515
λ¬Όλ‘  μˆ μ— μ·¨ν•œ μƒνƒœλ‘œ μž λ“€μ§€λ„ λ§κ³ μš”.
03:39
The final tip: have a wind-down routine.
77
219920
4147
λ§ˆμ§€λ§‰ νŒμ€ νœ΄μ‹μ„ μ·¨ν•˜λŠ” μΌμƒμž…λ‹ˆλ‹€.
03:44
I think many of us in the modern world,
78
224091
2833
제 μƒκ°μ—λŠ” ν˜„λŒ€ μ‚¬νšŒμ˜ λ§Žμ€ 뢄이
03:46

79
226948
3024
밀에 λ°”λ‘œ μž λ“€κΈ°λ₯Ό κΈ°λŒ€ν•©λ‹ˆλ‹€.
03:49
switch off the light,
80
229996
1460
μ‘°λͺ…을 끄고
03:51
and we think that sleep is also just like a light switch,
81
231480
3886
마치 수면이 μ „λ“± μŠ€μœ„μΉ˜μ™€ κ°™μ•„μ„œ
03:55
that we should immediately be able to fall asleep.
82
235390
2531
λ°”λ‘œ μž λ“€ 수 μžˆλ‹€κ³  μƒκ°ν•˜μ£ .
03:57
Well, unfortunately, sleep isn't quite like that
83
237945
3048
κΈ€μŽ„μš”, μ•ˆνƒ€κΉκ²Œλ„ μˆ˜λ©΄μ€ λŒ€λΆ€λΆ„ 그렇지 μ•ŠμŠ΅λ‹ˆλ‹€.
04:01
for most of us.
84
241017
1239
04:02
Sleep, as a physiological process,
85
242280
3191
μˆ˜λ©΄μ€ 생리적인 κ³Όμ •μœΌλ‘œ
04:05
is much more similar to landing a plane.
86
245495
3469
λΉ„ν–‰κΈ° μ°©λ₯™κ³Ό 훨씬 더 λΉ„μŠ·ν•©λ‹ˆλ‹€.
04:08
It takes time for your brain to gradually descend down
87
248988
4626
μ—¬λŸ¬λΆ„μ˜ λ‡ŒλŠ” 잠이 λ“€κΈ°κΉŒμ§€ μ–΄λŠ 정도 μ‹œκ°„μ΄ ν•„μš”ν•˜κ³

κ·Έλž˜μ•Ό κΉŠμ€ μž μ— λ“€ 수 있게 λ©λ‹ˆλ‹€.

μž λ“€κΈ° μ „ 20λΆ„ ν˜Ήμ€ 30λΆ„ λ™μ•ˆ,

심지어 ν•œ μ‹œκ°„ λ™μ•ˆμ€

95
273656
1692
μ œκ°€ λ§ˆμ§€λ§‰μœΌλ‘œ μ–ΈκΈ‰ν•  점은
