So, the current recommendation
32

1741
ืื– ื”ื”ืžืœืฆื” ื”ื ื•ื›ื—ื™ืช
01:31

01:37
or a little over 18 degrees Celsius.

It sounds cold but cold it must be.

The next tip is darkness.

ื”ื˜ื™ืค ื”ื‘ื ื”ื•ื ื—ืฉื›ื”.

ืื ื—ื ื• ื—ื‘ืจื” ืžืงื•ืคื—ืช-ื—ืฉื›ื”,
01:49
and, in fact, we need darkness specifically in the evening

In the last hour before bed,
42
122432
1967
ื‘ืฉืขื” ืฉืœืคื ื™ ื”ืฉื™ื ื”,
02:04
try to stay away from all of those computer screens

ื”ื˜ืื‘ืœื˜ื™ื ื•ื”ื˜ืœืคื•ื ื™ื.
02:10
Dim down half the lights in your house.

1990
ืื•ืœื™ ืชื•ืคืชืขื• ืžื”ืžื™ื“ื” ื‘ื”

at how sleepy that can make you feel.

ื–ื” ื™ื’ืจื•ื ืœื›ื ืœื—ื•ืฉ ื™ืฉื ื•ื ื™ื™ื.

If you'd like, you can wear an eye mask

ืื• ืœื”ืชืงื™ืŸ ื•ื™ืœื•ื ื•ืช ื”ืืคืœื”,

ื•ื–ื” ื™ืขื–ื•ืจ ืœื›ื ืœื•ื•ืกืช ื”ื›ื™ ื˜ื•ื‘

ืืช ื”ื•ืจืžื•ืŸ ื”ืฉื™ื ื” ื”ืงืจื™ื˜ื™ - ืžืœื˜ื•ื ื™ืŸ.
02:28
The next tip is walk it out.
52
148365
2579
ื”ื˜ื™ืค ื”ื‘ื ืฉืœื ื• ื”ื•ื ืœืœื›ืช.
02:30
Don't stay in bed awake for long periods of time.

02:35
And the general rule of thumb
54
155260
1748
ื•ื›ืœืœ ื”ืืฆื‘ืข ื”ื•ื
02:37
is if you've been trying to fall asleep
55
157032
2031
ืฉืื ื ื™ืกื™ืชื ืœื™ืฉื•ืŸ
02:39
and it's been 25 minutes or so,
56
159087
2461
ื‘ืขืจืš 25 ื“ืงื•ืช,
02:41
or you've woken up and you can't get back to sleep
57

ืื• ืฉื”ืชืขื•ืจืจืชื ื•ืœื ื”ืฆืœื—ืชื ืœื”ื™ืจื“ื ื—ื–ืจื”
02:44
after 25 minutes,
58
164492
1521
ืื—ืจื™ 25 ื“ืงื•ืช,
02:46
the recommendation is to get out of bed
59
166037
2844
ื”ื”ืžืœืฆื” ื”ื™ื ืœืฆืืช ืžื”ืžื™ื˜ื”
02:48
and go and do something different.
60
168905
1978
ื•ืœืœื›ืช ืœืขืฉื•ืช ืžืฉื”ื• ืื—ืจ.
02:50
And the reason is because your brain
61
170907
2286
ื•ื”ืกื™ื‘ื” ืœื›ืš ื”ื™ื ืฉื”ืžื•ื— ืฉืœื›ื

is an incredibly associative device.

2825
ื”ื•ื ืžื ื’ื ื•ืŸ ืžืื•ื“ ืืกื•ืฆื™ืื˜ื™ื‘ื™.
02:56
The brain has learned the association
63
176066
2698
ื”ืžื•ื— ืœืžื“ ืืช ื”ืงื™ืฉื•ืจ
02:58
that the bed is this trigger of wakefulness,

ืฉื”ืžื™ื˜ื” ื”ื™ื ื”ื˜ืจื™ื’ืจ ืœืขื™ืจื ื•ืช,
03:02
and we need to break that association.
65
182044
2603
ื•ืื ื—ื ื• ืฆืจื™ื›ื™ื ืœื ืชืง ืืช ื”ื–ื™ืงื” ื”ื–ืืช.
03:04
And by getting out of bed, you can go and do something else.
66
184671
3436
ื•ืื ืชืฆืื• ืžื”ืžื™ื˜ื”, ืชื•ื›ืœื• ืœืขืฉื•ืช ืžืฉื”ื• ืื—ืจ.
03:08
Only return to bed when you're sleepy.

ื—ื–ืจื• ืœืžื™ื˜ื” ืจืง ื›ืฉืืชื ื™ืฉื ื•ื ื™ื™ื.
03:11
And in that way, gradually,
68
191298
1651
ื•ื‘ื“ืจืš ื”ื–ื•, ื‘ื”ื“ืจื’ื”,
03:12
your brain will relearn the association
69
192973

ื”ืžื•ื— ืฉืœื›ื ื™ืœืžื“ ืžื—ื“ืฉ ืืช ื”ื–ื™ืงื”
03:16
that your bed is this place of sound and consistent sleep.

03:21
The fifth tip is something that we've actually

ืขืœ ื”ื˜ื™ืค ื”ื—ืžื™ืฉื™ ื›ื‘ืจ ื“ื™ื‘ืจื ื• ื‘ืขื‘ืจ ื‘ื”ืจื—ื‘ื” ื‘ืกื“ืจื” ื”ื–ื•,
03:23
already spoken about in detail in this series,
72
203848

03:27
which is the impact of alcohol and caffeine.

ื•ื”ื•ื ื”ื”ืฉืคืขื” ืฉืœ ืืœื›ื•ื”ื•ืœ ื•ืงืคืื™ืŸ.
03:30
So, a good rule of thumb here is to try to stay away
74
210493
2843
ืื– ื›ืœืœ ืืฆื‘ืข ื˜ื•ื‘ ื›ืืŸ ื”ื•ื ืœื ืกื•ืช ื•ืœื”ื™ืžื ืข

ืžืงืคืื™ืŸ ื‘ืฉืขื•ืช ืื—ื”"ืฆ ื•ื‘ืขืจื‘,
03:36
and certainly try not to go to bed too tipsy.

ื•ื‘ื˜ื— ืœื”ืฉืชื“ืœ ืœื ืœื”ื’ื™ืข ืฉื™ื›ื•ืจื™ื ืœืžื™ื˜ื”.
03:39
The final tip: have a wind-down routine.

I think many of us in the modern world,

ืจื‘ื™ื ืžืื™ืชื ื• ื‘ืขื•ืœื ื”ืžื•ื“ืจื ื™,

80
229996
1460
ืœื›ื‘ื•ืช ืืช ื”ืื•ืจ,
03:51
and we think that sleep is also just like a light switch,

ื•ืœื—ืฉื•ื‘ ืฉื”ืฉื™ื ื” ื”ื™ื ื›ืžื• ืžืชื’ ืชืื•ืจื”,
03:55
that we should immediately be able to fall asleep.
82

2531
ืฉื ื•ื›ืœ ืžื™ื“ ืœื”ื™ืจื“ื.
03:57
Well, unfortunately, sleep isn't quite like that

for most of us.

Sleep, as a physiological process,

ืฉื™ื ื”, ื›ืชื”ืœื™ืš ืคื™ื–ื™ื•ืœื•ื’ื™,
04:05

ื“ื•ืžื” ื™ื•ืชืจ ืœื”ื ื—ืชื” ืฉืœ ืžื˜ื•ืก.
04:08
It takes time for your brain to gradually descend down
