00:00:06Welcome to Living Circle. Okay, let's take a look at the health hot words. Seasonal cold. Xiao Hui from Quanyu sent a plea for help. She said,
00:00:10"Every time the season changes, I get a cold very easily. A common cold. Sore throat, sneezing,
00:00:13and it takes a long time to get better. And as soon as someone around me catches a cold, I'll
00:00:17follow suit and catch it too. I want to ask, is this situation an indication of
00:00:21a weak immune system?" Why do some friends get a cold so
00:00:25easily every time the season changes? What should
00:00:29we do?
00:02:00One word, not self-sufficient. So, the second one
00:02:03is some epidemic colds. As for the flu,
00:02:07generally, we also say, for example, in northern regions, it
00:02:11often occurs in autumn and winter. In the south, it may
00:02:14occur all year round. As for the flu,
00:02:18its systemic symptoms are very severe.
00:02:21。
00:02:27So, it is also different from our common one.
00:04:00Ah, so the sore throat is very obvious, affecting swallowing and speaking.
00:04:04For such patients, we can use some cold medicines to relieve
00:04:08the symptoms. As for relieving symptoms, it mainly
00:04:12has some, for example, vasoconstrictors and expectorants.
00:04:15These can make your nasal congestion not so severe.
00:04:19So, if we really take cold medicine, there are
00:04:23a few things to pay attention to. Sometimes, we rummage through
00:04:26the drawer at home, and the last cold medicine is still there. This
00:04:30time, we also got cold medicine. I want to get rid of the cold faster,
00:04:34so I take several cold medicines together. But in fact, this is
00:04:38not safe, because some cold medicines on the market are
00:04:42mixed preparations. In fact, some of their ingredients are
00:04:46the same. If you take them together, it means that you will
00:04:49exceed the standard, which will lead to an impact on our
00:04:53liver function. So, the second question is, even
00:04:57if the doctor prescribes it to you today,
00:05:12then at this time, because some ingredients
00:05:15affect blood pressure, or are not good for
00:05:19pregnant women, such patients
00:05:23should still cautiously take cold medicine according to the doctor's
00:05:26prescription.
00:06:13Ah, ensure sufficient sleep, because sleep is a time
00:06:17for many immune cells to repair.
00:06:20And don't eat too much greasy
00:06:24and fried food. Another point is that
00:06:28we also noticed that female friends
00:06:31are prone to relapse around menstruation. So, around
00:06:35menstruation, it is even more important to pay attention to adequate
00:06:39rest and not to be too tired. We have some.
00:09:42And it got worse and worse. Finally, a check-up at the hospital confirmed it was basal
00:09:46cell carcinoma. Later, we analyzed it and realized that his skin
00:09:50lesion was an early malignant skin tumor, but it looked
00:09:54too much like a senile plaque, so it was misdiagnosed. And the repeated stimulation
00:09:58of garlic was like adding fuel to the fire, greatly accelerating the progression of the disease.
00:10:02Here I want to highlight two important
00:10:06warning signs for everyone. Please remember them well. First, if a
00:10:09mole on your body suddenly appears with an unknown cause, and it's itchy, so itchy that
00:10:13you can't help but want to scratch and stimulate it. At this time,
00:10:17you need to be highly vigilant. Second, if the
00:10:21shape, color, or size of the mole changes, for example, the border becomes.
00:10:56In fact, senile plaques are not terrible. What is terrible is to mistake
00:10:59a skin lesion of a type of tumor for a senile plaque, and then use folk remedies
00:11:03to stimulate it. Don't let a small misdiagnosis lead to a big problem.
00:11:07In fact, only scientific judgment is the most responsible choice
00:11:11for oneself.
00:11:12。
00:11:18Classic Chinese 13 Boxes. This program is exclusively sponsored by China Time-honored Brand,
00:11:22Wang Shouyi 13 Boxes. Scientific fitness check-in.
00:11:26Friends, today we are going to recommend an energetic and very
00:11:29interesting fitness method. Punching exercises.
00:11:33As soon as the weather gets cold, the cold air invades, and many friends feel
00:11:37depressed and anxious. They don't want to go out after work
00:11:41and just stay at home scrolling on their phones, sleeping for a long time to recuperate.
00:11:45Who knew that the more they scrolled, the more irritable they became, and the more
00:11:49they slept, the more tired they felt? The stuffiness in their chest
00:11:52just wouldn't go away. Did they choose the wrong way
00:11:55to relax? Is there a gentle home exercise that can help
00:11:58us relieve our emotions? Hello everyone, I am
00:12:02Wang Jing, a member of the Living Circle Sports Expert Group. In winter, the time spent at home
00:12:06increases, and there are many trivial matters. If our spirit is highly
00:12:09tense for a long time, our shoulders and trunk muscles
00:12:13will involuntarily tense up, which will make us feel uncomfortable both physically and mentally.
00:12:17Simple static rest can hardly relieve the tension
00:12:20at the physical level. So, when it's cold, we need to actively
00:12:24move.
00:14:25You can imagine sending out the melancholy in your heart
00:14:28with your fist. Yes, don't rush to use force,
00:14:32mainly stretch. We inhale, sink our shoulders,
00:14:36pull in our core, and keep our whole body
00:14:39in a stable and relaxed state. Okay, exhale,
00:14:43clench your right fist, and punch forward straight.
00:14:47When we punch, we need to pay attention, the fist
00:14:50goes forward, the arm should be slightly bent.
00:14:53Don't lock it. The elbow should
00:14:57be bent. After the right arm is extended, quickly pull back
00:15:01the fist. Then we switch to the left arm, punch forward with the left hand.
00:15:05Very good, pull it back.
00:15:08The body will sway involuntarily. I always feel that using body strength
00:15:12makes the punch more powerful. You see, I not only use my fist, not only my arm, not
00:15:16only my shoulder, not only my body, but my legs also need to move. Do I have to kick out
00:15:20like this, or can we just use simple punching exercises with upper body movements?
00:15:24We,
00:15:38so when we do it, we don't just
00:15:41alternate punching with our arms, we need to cooperate with pushing
00:15:44off the ground, cooperate with turning our hips to complete it. Everyone
00:15:48should also pay attention when doing it. When punching, we need to sink our shoulders,
00:15:52don't shrug our shoulders.
00:15:53So it's not just about simply swinging our arms out, right?
00:15:57?
00:15:59It's about using the whole body's strength, as you said, from foot to hip to B and then to
00:16:03the entire movement.
00:16:04。
00:17:07Start
00:17:09one
00:17:13two
00:17:17When punching, we need to sink our shoulders, not shrug our shoulders. Dodging
00:17:21is the horizontal movement of our upper body. Don't
00:17:24lower your head. Punching is our
00:17:28trunk turning and hip rotating, driven by the shoulders.
00:17:32Very good. So, when everyone practices,
00:17:36you can practice several sets. We can do 10 times or 20 times per set,
00:17:40depending on your own situation. Xiaofu, how do you feel after adding dodging?
00:17:44At first, it was just, for example, our shoulders and arms,
00:17:48and now we've added our midsection and started doing it. When the
00:17:51range of motion is larger, we can activate more and more
00:17:55parts of our body from top to bottom. When dodging, our core
00:17:59needs to exert force, so when we do this exercise,
00:18:03our abdominal muscles are tense. These two movements can be very good.
00:21:35Changbai Mountain Range, a 133-kilometer long
00:21:38gigantic mountain range.
00:21:42It spans the border between China and North Korea, and is one of the oldest geological
00:21:45ancient homes in eastern Asia.
00:21:51At the heart of this ancient home, is its iconic
00:21:55pen. Changbai Mountain Tianchi Volcano,
00:21:58a dormant volcano.
00:22:01。
00:22:04Today, the waters of Tianchi are calm. Hundreds of thousands
00:22:08of tourists stand on its edge every year, marveling at the age
00:22:11of this clear blue water. But few
00:22:15people know how it roared and tore the sky apart more than
00:22:18a thousand years ago.
00:22:22That was one of the largest-scale volcanic eruptions
00:22:26in the world. Geologists call it
00:22:30the Millennium Eruption. This
00:22:33event was the largest and most significant
00:22:37volcanic eruption in the Northern Hemisphere in the past 2,000 years,
00:22:40with the most significant impact on global climate.
00:22:42。
00:22:46Then it became quiet.
00:23:07But this giant beast never died. What kind of power urged thousands of species
00:23:11to thrive and coexist on volcanic ash?
00:23:15When will it open its eyes again?
00:23:18The Nature China team, together with geologists
00:23:22and experts from various disciplines such as flora and fauna, formed a scientific expedition team.
00:23:26They delved deep into this breathing volcano
00:23:30to find answers.
00:23:32。
00:23:41Like humans, volcanoes also have their own life cycle.
00:23:45Changbai Mountain volcano has been alive for more than two million
00:23:49years. Within Changbai Mountain Global Geopark,
00:23:53there are more than 380 volcanic vents, with the highest density
00:23:57in East Asia. Among them, the most famous is Tianchi
00:24:00Volcano, which is also the only active
00:24:04volcano. On the
00:24:07astronomical peak on the north side of Tianchi, dozens of meters thick of
00:24:10basalt accumulation layers and multiple layers of lava witness the long
00:24:14and complex eruptive history of this
00:24:17volcano.
00:25:22Tianchi is one of the highest altitude lakes in the world, and also the deepest lake in China.
00:25:29The deepest part reaches 373 meters, with a water volume of about 2.04 billion cubic meters,
00:25:35making it
00:25:361.5 times the water volume of Lake Baikal, equivalent to 145 Hangzhou West Lakes.
00:25:42In this calm body of water, the system has never been active.
00:28:03Now we shine the light on this hot spring,
00:28:07and we can see bubbles
00:28:10coming up with this brick. Because the speed of gas victory
00:28:14is faster than the speed of advancement, so we monitor the composition of volcanic gas
00:28:18or the change in isotopes. This can help
00:28:21predict the state of the active volcano, which is very important
00:28:25for volcano
00:28:26monitoring.
00:28:32These bubbles are the pressure release valve and pressure gauge of the deep magma chamber.
00:28:36When will this volcano erupt again?
00:28:40It depends on the speed of pressure accumulation. This
00:28:44gas carries various information from the magma chamber.
00:29:37This observation cave is located about 3.5
00:29:41kilometers from Tianchi, on the mountainside. Here, the seismic
00:29:44array is like a stethoscope placed on the chest of the earth.
00:29:48Every heartbeat and the faint breathing of the magma chamber
00:29:52can be precisely captured and form observable
00:29:56waveform graphs. Researchers are analyzing and processing
00:30:00the data.
00:30:05However, breathing and heartbeats are not enough to fully judge
00:30:09the movement of underground magma. Finally, we also need to monitor surface
00:30:12deformation, which is the shape of the volcano.
00:30:16。
00:30:24GNSS and radar observations accurately
00:30:28detect changes in the entire mountain. They scan the surface
00:30:3124/7, capturing every millimeter of uplift, subsidence,
00:30:35expansion, or contraction, with millimeter-level precision.
00:30:38When the pressure in the magma chamber increases, these data
00:30:42will issue a warning. There are already 18
00:30:46such monitoring points, covering the north, south, and west
00:30:50slopes of Changbai Mountain, working 24 hours a day without interruption.
00:30:53。
