그동안은 운동을 열심히 하고 혈압과 콜레스테롤을 잘 관리하면 치매를 예방하거나 늦출 수 있다고 알려져 있었어요. 그래서 미국 연구진이 치매 위험이 높은 60~85세 어르신 513명을 모아 2년 동안 실제로 효과가 있는지 확인하는 연구를 진행했어요.

연구 결과, 열심히 유산소 운동을 하거나 혈압·콜레스테롤 약을 챙겨 먹은 분들이 그렇지 않은 분들에 비해 기억력이나 인지 능력이 눈에 띄게 좋아지지는 않았어요. 심혈관 건강 수치는 좋아졌지만, 뇌 기능 개선으로 바로 이어지지는 않은 거예요. 다만 연구 기간 동안 일반적인 고혈압 치료 기준이 엄격해지면서, 비교 대상이었던 일반 어르신들의 혈압도 같이 낮아진 점이 영향을 주었을 수 있다고 해요.

운동과 혈압 관리가 치매 예방에 소용없다는 뜻은 절대 아니에요. 심장과 혈관을 튼튼하게 해주는 효과는 확실하니까요. 전문가들은 노년기가 되어서야 관리를 시작하기보다는, 중년일 때부터 미리미리 건강한 생활 습관을 들이는 것이 치매 예방에 훨씬 중요할 수 있다고 조언하고 있어요.

치매를 막기 위해 언제부터, 얼마나 강하게 운동하고 관리해야 하는지 알아내기 위한 추가적인 연구들이 계속될 것으로 보여요.

나이가 들수록 혈압 관리와 심장 건강이 정말 중요해지죠. 최근 호주의 한 대학교 연구팀이 고혈압이나 뇌졸중 위험이 있는 성인 3만여 명을 대상으로 소금 섭취와 건강의 관계를 연구한 결과가 발표되었어요.

우리가 흔히 먹는 일반 소금 대신, 나트륨은 줄이고 칼륨을 더한 '대체 소금'을 사용해 보았는데요. 그 결과, 대체 소금을 먹은 사람들은 뇌졸중에 걸리거나 사망할 위험이 눈에 띄게 줄어들었다고 해요. 칼륨이 혈압을 낮춰주어 심장과 혈관에 가는 부담을 덜어주었기 때문이에요.

평소 짠 음식을 좋아하신다면, 갑자기 싱겁게 드시기보다는 요리할 때 소금 양을 조금씩 줄이거나 시중에서 파는 저나트륨 소금(대체 소금)을 활용해 보세요. 식단에서 소금만 살짝 바꿔도 큰 병을 예방하고 더 건강하게 지내실 수 있어요.

날씨가 따뜻해지면서 봄나들이나 등산 등 야외 활동을 계획하시는 분들이 많아졌어요. 하지만 겨울 내내 움직임이 적었던 탓에 갑자기 활동량을 늘리면 무릎에 무리가 갈 수 있답니다.

무릎을 보호하는 연골이 닳아서 생기는 '퇴행성 관절염'을 특히 조심하셔야 해요. 평소 무릎이 시큰거리거나 아프셨던 분들은 봄철 활동을 본격적으로 시작하기 전에 관절 상태를 꼭 점검해 보시는 것이 좋아요. 체중이 많이 나가면 무릎에 부담이 더 커지니 적절한 체중을 유지하는 것도 무척 중요하답니다.

무릎이 아프면 걷는 것조차 힘들어져서 일상생활이 크게 불편해져요. 약물이나 물리치료로도 통증이 계속된다면 참지 마시고 꼭 전문의와 상담하셔서 적절한 치료를 받으시길 바라요.

외출 전 가벼운 스트레칭으로 관절을 부드럽게 풀어주고 무리하지 않는 선에서 활동하신다면, 통증 없이 건강하고 즐거운 봄나들이를 다녀오실 수 있을 거예요.

관절이 아프거나 염증이 심할 때 '뼈 주사'라고 불리는 스테로이드 치료를 받는 분들이 많으신데요. 통증이 마법처럼 사라져서 기적의 약이라고도 불리지만, 그만큼 조심해야 할 부분도 많다는 건강 칼럼이 나왔어요.

스테로이드가 당장의 통증은 금방 없애주지만, 우리 뇌에서 기억을 담당하는 '해마'의 신경세포를 다치게 할 수 있다고 해요. 이렇게 되면 우리 몸이 통증을 스스로 이겨내던 건강한 기억을 잃어버리게 된답니다. 게다가 약 성분이 혈관을 타고 온몸으로 퍼지기 때문에 몸 전체에 무리를 줄 수도 있어요.

무릎이나 허리가 아프다고 무조건 스테로이드 주사나 약에만 의존하시면 안 돼요. 당장의 아픔을 가라앉히는 데는 꼭 필요할 때만 쓰시고, 평소에는 가벼운 운동이나 바른 자세로 뼈와 근육을 튼튼하게 하는 진짜 치유법을 실천해 보세요.

Military clashes between the US, Israel, and Iran have sharply escalated Middle East tensions. In response, Iran has effectively blocked the Strait of Hormuz, a crucial global oil route.

Iran announced that only friendly, non-hostile ships can pass, strictly banning vessels linked to the US or Israel. Consequently, over 3,200 ships are currently stranded at sea, with some reportedly paying millions of dollars in tolls to Iran for safe passage.

This strait is a major route for global oil supplies. If ships cannot pass on time, global oil prices will skyrocket, ultimately driving up the cost of groceries and everyday living expenses.

Iran is even drafting new laws to control the waterway, making it unlikely for ships to navigate freely as they did before in the near future.

Military tensions between the US and Iran are escalating. Although US President Trump announced a 5-day delay in attacking Iran's power plants, reports indicate preparations for a large-scale ground troop deployment are underway.

The US is reportedly considering mobilizing about 8,000 troops, including Marines and airborne units, to occupy Iran's Kharg Island. Kharg Island is a crucial hub handling 90% of Iran's crude oil exports. The US appears to be planning to seize this location to cut off Iran's funding and apply intense pressure.

If the war in the Middle East expands, global oil prices could skyrocket. Higher oil prices would lead to increased inflation, raising the cost of living, so the situation requires close monitoring.

It remains to be seen over the next few days whether the US will actually launch a ground assault or if this is a tactic to intimidate Iran into favorable negotiations.

Amid escalating Middle East conflicts, Qatar, the world's second-largest gas exporter, suffered a missile attack on its production facilities. The severe damage could take 3 to 5 years to repair.

The Qatari government officially notified four countries, including South Korea, that it cannot deliver the promised gas due to the war. This is called a 'force majeure' declaration, meaning they are exempt from liability due to unavoidable circumstances.

Fortunately, the government has secured enough gas for this year, so there will be no immediate shutoffs. However, having to buy expensive gas from elsewhere increases the likelihood of higher electricity and winter heating bills later this year.

If the Middle East conflict persists, it could drive up prices not only for gas but also for everyday goods like plastics, prompting the government to prepare countermeasures.

최근 미국과 이란의 갈등으로 중동 지역에 전쟁이 벌어지면서 전 세계 경제가 크게 흔들리고 있어요. 이에 대해 세계적인 경제 전문가가 앞으로의 상황을 전망하는 강연을 했답니다.

전문가들은 이번 중동 전쟁의 충격이 트럼프 미국 대통령의 관세 정책보다 우리 경제에 더 큰 타격을 줄 거라고 봐요. 특히 이란이 석유와 가스를 무기처럼 쓰면서, 전쟁이 끝나도 기름값이 예전처럼 싸지기는 어려울 거라고 해요. 게다가 천연가스는 농사에 쓰이는 비료의 원료이기도 해서, 가스가 부족해지면 전 세계 농업이 타격을 입을 수 있다고 해요.

기름값이 계속 비싸지면 당장 자동차 주유비나 난방비 부담이 커져요. 게다가 비료가 부족해져 농작물 수확량이 줄어들면, 우리가 매일 먹는 쌀이나 채소 같은 밥상 물가도 크게 오를 수 있어 걱정이에요.

미국은 전쟁 비용 때문에 물가가 더 오를 수 있고, 이자율(금리)도 다시 높아질 가능성이 있어요. 우리나라도 물가 오름세에 단단히 대비해야 할 것 같아요.

Schizophrenia is a mental illness. Existing drugs are effective at calming hallucinations and delusions, but they have side effects that significantly degrade brain functions like memory and judgment, causing patients a lot of distress.

Researchers at Northwestern University in the US have developed a new drug that completely eliminates these drawbacks. It controls hallucinations while keeping brain functions healthy. Notably, it only requires a once-weekly injection instead of daily pills, earning praise as being as groundbreaking as the global weight-loss drug 'Ozempic'.

If commercialized, it will be much easier for schizophrenia patients to maintain a normal daily life without side effects. It is expected to greatly ease the burden not only on the patients themselves but also on their families who have struggled while caring for them.

The researchers plan to begin human clinical trials soon to confirm the drug's efficacy and safety. We hope the trials are completed successfully so it can be used in actual hospitals as soon as possible.

There have been recent military clashes between the US and Iran. Many countries worried that the Strait of Hormuz, a crucial global oil transit route, might be blocked.

President Trump claimed he effectively won the war, stating he received a 'big gift' from Iran regarding oil transit and that Iran promised to give up nuclear weapons. However, the Iranian government strongly refuted this as 'fake news,' denying any direct negotiations with the US. The conflicting claims have caused confusion.

Global oil prices can fluctuate significantly depending on how the Middle East conflict is resolved. Rising oil prices can directly burden domestic inflation and living costs.

While the US is confident the conflict will end soon, Iran is strongly pushing back. The tense standoff and truth battle between the two nations are expected to continue.

Recent conflicts between the US, Israel, and Iran have heightened war tensions in the Middle East. To resolve this, the US and Iran have cautiously begun talks through third countries like Pakistan.

The US presented 15 conditions to Iran, including halting weapons support and abandoning nuclear development. Conversely, Iran demanded the US envoy completely end the war and lift crippling economic sanctions. The two sides are at a standoff with differing demands.

The Middle East is a major source of global oil and natural gas imports. Peace in this region could stabilize oil prices and inflation, ultimately reducing the cost of living worldwide.

While it's positive that the two nations have started talking, deep mutual distrust makes an immediate agreement unlikely. The ongoing negotiation process requires close monitoring.

As we age, dry eyes and inflammation often require frequent use of eye drops. Regular drops wash away quickly with tears, making constant reapplication a hassle.

Researchers at the University of Pittsburgh developed 'living eye drops' that heal wounds with a single dose. They genetically modified beneficial bacteria living under our eyelids to stay in the eye and secrete anti-inflammatory agents 24/7. In mice trials, wounds healed much faster than with regular drops.

If commercialized, this technology will eliminate the need for frequent eye drops, protecting eye health with a single treatment. It will be especially welcome news for those suffering from severe dry eye or corneal wounds.

As it is still in the animal testing phase, further validation is needed for human use. Researchers are also developing techniques to safely remove the microbes after treatment, so we will have to wait a bit longer.

우리나라는 그동안 외국에서 전투기를 사 와서 국방을 책임졌어요. 하지만 2001년부터 '우리 하늘은 우리 기술로 만든 전투기로 지키자'는 목표를 세우고 오랜 시간 연구와 개발을 이어왔답니다.

드디어 우리나라 기술로 만든 초음속 전투기 'KF-21'의 첫 번째 완성품이 세상에 나왔어요. 이재명 대통령은 출고식에 참석해 '우리 기술로 자주국방의 위용을 떨치게 됐다'며 기뻐했지요. 이로써 우리나라는 첨단 전투기를 스스로 설계하고 만들어내는 세계 8번째 국가가 되었어요.

당장 우리 지갑에 돈이 들어오는 일은 아니지만, 튼튼한 국방력은 우리 국민이 안심하고 일상을 누릴 수 있는 든든한 울타리가 되어줘요. 게다가 다른 나라에 이 전투기를 수출하게 되면 우리나라 경제에도 큰 보탬이 될 수 있답니다.

올해 하반기부터 우리 공군에 순차적으로 배치되어 낡은 전투기들을 대신할 예정이에요. 인도네시아 등 다른 나라로의 수출도 활발하게 추진될 것으로 보여요.

Anyone diagnosed with cancer experiences immense stress due to fears of recurrence or treatment side effects. Recently, researchers at a Polish medical university studied how this stress actually impacts cancer treatment.

The study found that chronic stress can negatively affect cancer progression. Researchers emphasized that keeping the mind at ease is as crucial to cancer treatment as managing pain and maintaining nutrition.

Cancer patients and their families should pay special attention to finding mental stability alongside physical treatment. Warm words and emotional support from those around them can greatly aid the patient's recovery.

In the future, programs that care for patients' psychological states and stress management therapies are expected to become increasingly important in hospital cancer treatments.

As the recent Middle East war nears a month, global oil prices and inflation are surging. Strict preparation is needed as this heavily impacts our economy and security.

The government launched an 'Emergency Economy HQ' led by the Prime Minister. It will monitor and devise daily measures across five sectors: prices, energy, finance, and livelihoods. They are preparing extra budgets to curb oil prices and support citizens.

Rising prices and oil costs will increase household expenses for a while. The government encourages energy-saving habits like using public transit and saving electricity.

As the government plans to inject massive funds to stabilize the economy, we will need to monitor how the market situation calms down.

Prolonged conflicts in the Middle East are causing global economic instability, including rising oil prices and inflation. The government must act swiftly as this could severely impact the South Korean economy.

A special 'Emergency Economic Situation Room' was set up in the Blue House to directly monitor the Mideast crisis's economic impact. Five teams covering prices, energy, finance, and livelihoods will check daily and prepare measures. The Prime Minister and Deputy PM will also hold frequent weekly meetings.

The government will work to prevent sharp increases in oil and living costs. By prioritizing issues directly affecting our wallets, such as grocery prices and loan interest rates, they aim to provide some relief to the public.

The government will regularly brief the public on their assessments, preparing for worst-case scenarios. Swift government responses are expected to continue until the Middle East situation stabilizes.

Recently, a blonde female soldier pictured walking the runway or posing at the White House with US President Trump went viral online. Over 1 million people followed her social media.

It turns out she wasn't a real person but a fake created by AI. The US Army confirmed no such soldier exists, and a closer look at the photos revealed messed-up name tags and rank insignias. The ultimate goal was to lure people to a paid adult site to make money.

AI technology has advanced so much that it's hard to distinguish real from fake just by looking at photos. Don't blindly trust overly perfect or provocative images online; always be cautious and question if they might be fake.

Park Wang-yeol was imprisoned in the Philippines for murdering three Koreans in 2016. Shockingly, he secretly used a smartphone in prison to sell massive amounts of drugs to Korea, causing a major issue.

The Korean government has long sought to punish this dangerous criminal under domestic law. Earlier this month, the presidents of Korea and the Philippines met and discussed this directly, leading to his extradition after 9 years. Police plan to thoroughly investigate how he smuggled drugs and who his accomplices were.

Drug crimes have been frequently reported in the news lately, causing much concern. With the capture of this drug smuggling ringleader, our society and our children's surroundings will become a bit safer.

After the police investigation, he will face severe punishment in a Korean court. Authorities also plan to track down and confiscate all the money he earned through his illicit activities.

Concerns over oil import disruptions have grown due to the recent US-Iran war. Since garbage bags are made from petroleum, some people started hoarding them out of fear of a shortage.

President Lee Jae-myung checked the inventory of garbage bags. He ordered that if oil import issues make production difficult, recycled materials should be used to make the bags.

There is no need to worry about an immediate shortage. The government confirmed that there is an ample nationwide inventory lasting more than three months on average.

Even if the war prolongs, countermeasures are being prepared to produce bags using recycled materials, so you can just buy them as needed like usual.

Park Wang-yeol, who murdered three Koreans in the Philippines, was caught smuggling drugs into Korea via smartphone from prison and was extradited after 9 years.

Police are investigating how Park smuggled drugs from prison. They are focusing on identifying domestic distributors and accomplices who aided his crimes.

With rising concerns over drug crimes, this investigation aims to block distribution channels, helping to create a safer society free from drug threats.

Police plan to arrest Park and confiscate his drug profits. Hidden accomplices are also expected to be caught soon.

Calls to curb speculation and stabilize housing prices are growing. In response, the government is considering new measures timed with the end of tax benefits for multiple homeowners in May.

The main point is that 'property taxes' for those owning multiple homes may rise. This is an annual tax paid just for owning property. The government vowed to use all means, including tax and loan rules, to block speculation.

If you own multiple homes, your annual tax burden could increase significantly. Those planning to sell should carefully check how the tax system changes.

Specific tax hike proposals and real estate regulations will be announced after May, so it is advisable to keep a close eye on government announcements.

Park Wang-yeol was imprisoned in the Philippines for murdering three Koreans in 2016. However, it was revealed that he secretly used a mobile phone in prison to sell massive amounts of drugs to Korea.

The so-called 'drug lord' has finally been extradited to Korea. This happened about a month after the South Korean president personally requested it from the Philippine president. Park, who boldly committed crimes and even called his lover into the prison, will now face a thorough investigation in Korea for drug distribution.

This sends a strong warning that criminals who flee abroad or hide in foreign prisons to spread drugs in our society will be caught. It will greatly help protect our children from the dangers of drugs.

Prosecutors and police plan to track down all of Park's accomplices in Korea and confiscate all illegal assets he accumulated through drug sales.

Some people are startled when their ankles suddenly won't move and their toes drag. Many worry it's a stroke, but it's highly likely to be 'peroneal neuropathy,' a nerve issue in the leg.

Peroneal neuropathy occurs when the nerve below the knee is compressed for a long time. Sleeping with one leg pressed, squatting, or crossing legs are main causes. Its main feature is ankle weakness causing toe dragging while walking.

Dragging toes increases the risk of tripping and falling. Elderly people with weak bones must be especially careful, as falls can lead to severe injuries.

If caught early, it can improve quickly with posture correction, medication, or physical therapy. Reduce habits like crossing legs, and visit a doctor promptly if symptoms appear.

70-year-old actress Lee Kyung-jin recently appeared on a YouTube show, candidly sharing her past struggles with breast cancer.

Lee was devastated when initially told she needed a full mastectomy, tearfully describing the fear of losing her breasts as akin to losing an arm. Fortunately, with the help of fellow actress Go Doo-shim, she got a second opinion at another hospital, miraculously avoided the mastectomy, and successfully completed her treatment.

Having overcome the severe illness, Lee has regained her weight and maintains her health by working out regularly. Her desire to give hope to other cancer patients that they too can live healthily is inspiring many people.

An Indian woman in her 20s visited a hospital with a persistent cough, phlegm, and fever. She was initially diagnosed with tuberculosis and took medication for four months, but her symptoms did not improve at all.

When the medication failed, she underwent a detailed examination. Surprisingly, a condom was found in her lung. It is a rare case where a foreign object accidentally entered her airway during sexual intercourse and ended up in her lung.

This is a highly unusual incident from abroad, so there is no need to worry. However, it serves as a reminder that if common symptoms like a cough do not improve after prolonged medication, it is safe to get a detailed medical checkup.

Vegetable prices fluctuate often due to weather and harvest yields. This article analyzes the wholesale auction prices of tomatoes, carrots, potatoes, eggplants, and paprikas as of March 25.

While specific figures aren't detailed here, wholesale auction prices indicate current supply levels. Prices rise when bad weather reduces harvests and fall when yields are abundant.

Wholesale auction prices are reflected in local retail markets a few days later. Knowing these trends helps consumers save on groceries and plan their meals efficiently.

As we age, belly fat increases and losing weight becomes harder. Broadcaster Ahn Sun-young, who recently lost 11kg and maintained a healthy figure, is making headlines by revealing her morning diet.

Ahn's morning secret is 'unsweetened yogurt' and 'plant-based (vegan) protein'. Unsweetened yogurt is rich in good probiotics, which strengthen the gut and help lose belly fat. Mixing protein powder into it keeps you full and prevents sudden blood sugar spikes.

How about trying unsweetened yogurt instead of bread or rice in the morning? It's a win-win as it digests well and supports gut health. However, some store-bought yogurts contain a lot of sugar, so make sure to choose 'unsweetened' ones.
