00:00:04.049 --> 00:00:06.669 
Sleep risks that people with high
blood pressure easily encounter during Tet 

00:00:06.669 --> 00:00:09.489 
1. Insomnia, not sleeping deeply 

00:00:09.489 --> 00:00:13.349 
The last days of the year often entail
many gathering, moving, and entertaining activities. 

00:00:13.809 --> 00:00:16.875 
Going to bed late, sleeping less, or
interrupted sleep makes the sympathetic 

00:00:16.875 --> 00:00:19.429 
nervous system more active, increasing
heart rate and blood pressure. 

00:00:20.069 --> 00:00:22.952 
Research shows that sleeping less than 6
hours per night is associated with a 

00:00:22.952 --> 00:00:25.629 
higher risk of high blood pressure than
people who sleep enough 7-8 hours. 

00:00:25.629 --> 00:00:28.608 
In people who already have hypertension,
lack of sleep also makes blood 

00:00:28.608 --> 00:00:29.849 
pressure more difficult to control. 

00:00:30.569 --> 00:00:32.329 
2. Nighttime high blood pressure 

00:00:32.329 --> 00:00:36.229 
Normally, blood pressure will decrease
slightly at night, the phenomenon of low blood pressure. 

00:00:36.629 --> 00:00:40.529 
However, when sleeping poorly or waking
up frequently, this phenomenon may not occur. 

00:00:41.029 --> 00:00:44.049 
Non-low blood pressure increases the
risk of stroke and cardiovascular events. 

00:00:44.049 --> 00:00:47.449 
During Tet, using alcohol and beer in
the evening, eating salty food or eating 

00:00:47.449 --> 00:00:50.849 
too full before bed can cause night
blood pressure to rise higher than normal. 

00:00:51.609 --> 00:00:53.709 
3. Halting breathing when sleeping heavier 

00:00:53.709 --> 00:00:57.469 
Sleep apnea due to blockage is an
important risk factor for high blood pressure. 

00:00:57.949 --> 00:01:01.199 
Alcohol and beer are often used a lot
during holidays, stretching the muscles 

00:01:01.199 --> 00:01:03.449 
of the throat, making snoring and sleep apnea worse. 

00:01:04.409 --> 00:01:07.516 
Repeated lack of oxygen overnight can
cause blood pressure to rise for a long 

00:01:07.516 --> 00:01:09.069 
time and increase the risk of arrhythmia. 

00:01:09.069 --> 00:01:12.069 
4. Irregular heartbeat due
to lack of sleep 

00:01:12.069 --> 00:01:16.369 
Lack of sleep and stress can increase
stress hormones such as cortisone and adrenaline. 

00:01:17.029 --> 00:01:20.408 
In people with hypertension, this can
trigger palpitations, rapid heartbeats, 

00:01:20.408 --> 00:01:23.449 
or arrhythmia, especially when combined
with alcohol and coffee.
