Why do we get a hangover
when we drink too much alcohol?

2
00:00:07.097 --> 00:00:10.750
Reason number 1: 
Alcohol stimulates the kidneys,

3
00:00:10.750 --> 00:00:12.619
causing them to 
produce more urine.

4
00:00:12.630 --> 00:00:16.550
So paradoxically, the more we drink,
the more dehydrated we become.

5
00:00:18.680 --> 00:00:22.720
With less water in our system,
the brain doesn’t get enough blood,

6
00:00:22.787 --> 00:00:25.047
leading to headaches.

7
00:00:25.353 --> 00:00:29.537
On top of that, the extra urine
carries away essential minerals,

8
00:00:29.537 --> 00:00:34.420
which can lead to an electrolyte imbalance – 
and headaches, nausea and fatigue.

9
00:00:35.247 --> 00:00:39.110
Reason number 2: 
The liver works at full speed

10
00:00:39.110 --> 00:00:44.093
to break down the  alcohol, leaving it too busy 
to produce enough blood sugar –

11
00:00:44.093 --> 00:00:47.016
causing blood sugar levels to drop.

12
00:00:49.240 --> 00:00:52.813
Adding physical activity to
the mix heightens the effect.

13
00:00:53.280 --> 00:00:57.493
Low blood sugar can lead to
dizziness and circulatory problems.

14
00:00:59.640 --> 00:01:01.960
Reason number 3: 
ethanol.

15
00:01:01.980 --> 00:01:05.313
When the body breaks down ethanol 
— commonly known as alcohol —

16
00:01:05.313 --> 00:01:10.340
it produces acetaldehyde, a toxic
compound that can cause headaches,

17
00:01:10.340 --> 00:01:13.246
stomach upset, and even memory loss.

18
00:01:13.660 --> 00:01:18.660
With regular alcohol consumption,
acetaldehyde damages organ membranes,

19
00:01:18.660 --> 00:01:20.130
especially in the liver.

20
00:01:20.140 --> 00:01:23.140
Excessive drinking over time
can lead to liver cirrhosis.

21
00:01:24.760 --> 00:01:28.800
By the way, many foods naturally
contain ethanol, such as

22
00:01:28.800 --> 00:01:33.240
fruit juices, bread, and kefir —
but only in tiny amounts.

23
00:01:34.240 --> 00:01:39.000
So don’t worry – no one’s ever been
known to get a hangover just from

24
00:01:39.000 --> 00:01:42.246
overdoing it on the bread!
