Some parts of your body are inherently sensitive. So, it is understandable if the idea of using something called "low-intensity shockwave therapy (LISWT)" to treat erectile dysfunction (ED) makes you squirm. However, research has shown that this method is emerging as a potential treatment for ED, targeting the root cause of vascular issues that impede blood flow to the penis. It is pertinent to note that although this therapy is promising, it is not yet FDA-approved and remains experimental.

Here's How LISWT Works

Shockwave therapy is a non-invasive treatment that uses sound waves to help heal damaged tissues. In the case of ED, this therapy stimulates and strengthens blood vessels in the penis, improving blood flow and supporting erections. Initially developed to treat kidney stones and chronic wounds, LISWT’s use in ED is relatively new but has shown positive results in treating vascular ED.

This treatment is effective ...

  • For individuals with mild to moderate vascular ED.
  • For patients who respond well to ED medications like sildenafil (Viagra)
  • It is not suitable for ED caused by nerve damage or psychological factors.

Around 75% of patients report satisfactory improvements. This procedure involves multiple 15-minute sessions over a month and results last one to two years, and the treatment is pain-free for most patients. However, this treatment is costly, averaging over $3,000, and is often not covered by insurance due to its experimental status. At-home devices are not effective, as they typically use radial wave therapy, which lacks the energy needed to address ED.

What Is Erectile Dysfunction?

Erectile dysfunction, also named impotency or impotence, is a penile disorder that affects an individual’s ability to get or hold an erection during sexual intercourse. During intimate moments, one's feelings share a pivotal role in getting and keeping an erection firm.

For this, one may feel confident, relaxed and aroused. While problems with erection are normal sometimes, they can occur due to causes such as psychological conditions, prescription drugs, and underlying health conditions. Excessive smoking or drinking can also trigger the condition.

Symptoms of Erectile Dysfunction (ED)

Occasional Erections: Difficulty achieving an erection consistently before sexual intercourse.

Erection Maintenance Issues: Ability to achieve an erection but difficulty maintaining it during intercourse.

Complete Inability: Inability to achieve an erection at all.

Dependence on Stimulation: Constant need for external stimulation to maintain an erection.

Reduced Libido: Decreased sexual desire experienced by some individuals with ED.

Can ED Be Prevented?

Yes, ED is preventable. Adopting a healthy lifestyle can help to prevent erectile dysfunction. Additionally, changes such as quitting smoking, limiting alcohol intake, engaging in cardiovascular exercises (jogging, running, swimming or bicycling), consuming a low saturated fat diet (fruits, whole grains and vegetables), maintaining a healthy weight and getting quality sleep can be immensely beneficial in the prevention journey.

Flu Activity Has Not Peaked Yet, Says CDC Amid Record Breaking Season

Updated Jan 13, 2026 | 01:08 PM IST

SummaryThe US is facing record flu cases, with hospitalizations rising and CDC warning activity has not yet peaked. About 40,000 were hospitalized in early January. A mutated H3N2 “K” variant is driving severe illness. Vaccination rates remain below 40 percent, but experts say current flu shots still reduce complications nationwide today.

While US has already reported record breaking flu cases, with hospitalizations and deaths continuing to rise, the Centers for Disease Control and Prevention (CDC) says that the flu activity may not have peaked yet. Around 40,000 people were admitted to the hospital with flu during the week ending with January 3. The CDC published the data that showed around 10% more than the 36,000 hospitalizations from the week before. There were 12 flu hospitalizations for every 100,000 people in the US last week.

CDC has also noted that vaccination "has been shown to reduce the risk of flu and its potentially serious complications". However, only 130 million doses of vaccine have been distributed, which covers less than 40% of the US population.

While the CDC data showed an increase in flu-like activity, and that the records have reached the highest since the initiation of the agency's tracking around 30 years ago, some indicators this week have fallen. CDC says that this does not mean the season has reached its peak, rather the downtick "could be due to changes in healthcare seeking or reporting during the holidays." CDC says more flu cases may come in the weeks ahead.

The Worst Flu Season Could Become Worse

This year's flu came after the flu vaccination was made, which means the current vaccination does not align with the mutation, however, experts have pointed out that it still continues to offer protection against the illness. This season's flu is a mutation of H3N2 or influenza A, called the subclade K, or what people are calling 'super flu'.

This is the culprit in rising flu cases, globally. The World Health Organization (WHO) on its website said that K variant marks "a notable evolution in influenza A (H3N2) viruses". Some are also questioning the effectiveness of this season's influenza vaccine against the strain.

The flu virus is highly contagious and spreads easily in crowded places, especially during the colder months.

In some cases, the infection can progress to the lungs, which could lead to complications like bronchitis or pneumonia. Yale Medicine too notes that this virus could attack the respiratory system, including throat, nose, and lungs.

What Are The Common Symptoms This Season For The Flu?

K variant causes more intense flu symptoms, they include:

  • Fever
  • Chills
  • Headache
  • Fatigue
  • Cough
  • Sore throat
  • Runny nose

Are The Old Vaccines Effective Against This New Variant?

"The vaccine remains the most effective means to prevent disease. We still want to encourage people to get the vaccine," said Professor Antonia Ho, Professor and Honorary Consultant in Infectious Diseases at the University of Glasgow. Experts have stressed enough on the immunity that one can receive from the vaccine that that these flu jab remain the best defense against the flu, even though the current strain circulated may have drifted away from the strain included in this year's jab.

Data from the UK Health Security Agency (UKHSA) also show that vaccines is performing as expect, despite the emergence of subclade K.

What Is the 3-3-3 Rule? Korea’s Simple Brushing Method Explained

Updated Jan 13, 2026 | 09:00 AM IST

SummaryThe Korean 3-3-3 brushing rule advises brushing teeth three times daily, within three minutes of eating, for at least three minutes. Popular in Korea due to food habits, studies link it to better periodontal health. Experts say brushing after meals helps reduce plaque, cavities, and gum disease and bad breath.

We know of the Japanese way of walking, and the Chinese way of losing weight by getting yourself enrolled in "Fat Prison", but did you know that there is a Korean Way of doing things. And no, this is not skincare. We are talking about the Korean way of brushing, using the 3-3-3 rule.

This method recommends brushing thrice a day, within three minutes of eating, and for at least three minutes of duration.

This is especially for when we eat sugary foods or snacks in between the meals. Korean cuisine uses a lot of spices, especially garlic. This is why, Koreans believe brushing their teeth is important so the smell does not linger.

In fact, many Koreans carry a toothbrush and toothpaste at work.

The Korean Way Of Brushing: A Study

A study conducted between 2012 and 2014 by the Division of Chronic Disease Surveillance, Cheongju, Korea, under the Korean Centers for Disease Control and Prevention and the Korean Ministry of Health and Welfare, Sejong, Korea, assessed the association between oral health and periodontal disease. The study used nationally representative data from the Korean National Health and Nutrition Examination Survey (KNHNES).

The study used a detailed, multi-stage survey method designed to fairly represent the non-institutionalized civilian population. Trained health workers visited participants in their homes and carried out standardized health examinations.

Initially, 23,626 people were considered for the KNHANES survey. The analysis focused on 18,382 adults aged 19 and above. After excluding participants with no data on periodontal health, the sample dropped to 15,754. The final analysis included 14,527 individuals with complete information. The study was approved by the Institutional Review Board of the Korean Centers for Disease Control and Prevention and followed the ethical principles outlined in the Helsinki Declaration.

Researchers recorded when participants brushed their teeth—before or after breakfast, lunch, dinner, after snacks, or before bedtime—and whether they used additional oral care products such as dental floss, mouthwash, interdental brushes, electric toothbrushes, tongue cleaners, or denture-specific tools. Daily brushing frequency was calculated based on how many times teeth were brushed each day. Information on tooth pain, past orthodontic treatment, and dental checkups within the past year was also collected.

The findings showed that people who brushed after lunch and before bedtime had lower rates of periodontal disease, while brushing after dinner was linked to fewer severe cases. Using additional oral care tools, especially dental floss and powered toothbrushes, was also associated with better periodontal health.

In many countries, it is a norm to brush your teeth at least twice a day. However, in Korea, the 3-3-3 brushing technique is more than a norm.

Is Brushing Three Times A Day Too Much?

While brushing is a great habit, one may be worried if brushing too much can lead to enamel erosion. However, brushing three times a day may not be excessive, as the American Dental Association recommends brushing teeth after every meal as ideal for optimal oral health.

The reason is that bacteria and food particles can accumulate on our teeth within minutes of eating or drinking. If left uncleaned, this could also lead to plaque buildup and tooth decay. This could lead to cavities and other dental issues.

This Common Vitamin Deficiency Can Look Like Dementia, Doctors Warn

Updated Jan 13, 2026 | 12:00 AM IST

SummaryVitamin B12 deficiency can cause memory loss and other symptoms that mimic dementia. Experts and the NHS explain the warning signs, risks, treatment options, and foods rich in B12.

People troubled by increasing forgetfulness are being advised to have their vitamin levels checked, as a shortage of one essential nutrient can cause symptoms that closely resemble dementia. According to the NHS, a deficiency in a key vitamin may lead to neurological issues that affect the nervous system, including problems with memory.

As per Mirror, Dr Eric Berg, DC, has also drawn attention to what he calls the “leading vitamin deficiency that mimics dementia,” identifying vitamin B12 as a major concern. Adequate levels of this nutrient are vital because it helps form red blood cells that carry oxygen through the body, supports DNA production and regulation, and converts food into usable energy.

Dr Berg, well known for promoting healthy ketosis and intermittent fasting, is the author of the bestselling book The Healthy Keto Plan and runs Dr Berg Nutritionals. He has since moved away from clinical practice to focus on sharing health information through online platforms.

Why Is Vitamin B12 Important?

Vitamin B12 is essential for the healthy functioning of the central nervous system and plays a key role in maintaining clear thinking and memory. When levels drop, people may experience weakness, numbness, difficulty walking, nausea, unintended weight loss, irritability, extreme tiredness, and a fast or irregular heartbeat.

Bones, hair, skin, and nails may also suffer. Dr Berg explains: “Vitamin B12 is essential for normal brain function. Without it, symptoms similar to dementia can develop. This vitamin is mainly found in animal-based foods, although some microbes can produce it. Low intake of animal products is the most common reason for vitamin B12 deficiency.”

Research suggests that low B12 levels can impair nerve function and may contribute to conditions such as dementia, peripheral neuropathy, or subacute combined degeneration. A deficiency can also interfere with DNA synthesis and cause homocysteine levels to rise.

What Does The NHS Say?

On its official website, the NHS states: “Most cases of vitamin B12 or folate deficiency can be treated easily and effectively, so complications are uncommon. However, complications may sometimes occur, particularly if the deficiency has been present for a long time. If neurological problems develop, they can occasionally be permanent.”

The NHS explains that a lack of vitamin B12 may lead to neurological symptoms such as:

  • vision problems
  • memory loss
  • pins and needles
  • loss of physical coordination (ataxia), which can affect speech or walking
  • damage to parts of the nervous system (peripheral neuropathy), especially in the legs

A study published in 2020 found a “clear association between low vitamin B12 levels and progressive cognitive impairment.” Researchers added that more large-scale studies are needed to confirm these findings and to see whether correcting the deficiency can slow cognitive decline.

More than one in ten older adults are estimated to have low vitamin B12 levels. In addition to memory problems, a deficiency may cause other neurological and psychological symptoms, including:

  • confusion
  • difficulty with thinking and reasoning
  • tingling or numbness in the hands and feet
  • poor balance and coordination
  • fatigue
  • weakness
  • vision disturbances
  • peripheral neuropathy affecting the nervous system
  • depression, anxiety, paranoia, and delusions
  • incontinence
  • loss of taste and smell

Can A Vitamin B12 Deficiency Be Treated?

If a vitamin B12 deficiency is diagnosed, treatment usually involves high-dose supplementation, either through injections or oral supplements. GPs may arrange regular blood tests to monitor B12 levels over time.

As per The Mirror, the longer the deficiency goes untreated, the higher the risk of permanent damage. That said, it is often reversible, with many people noticing marked improvement within three to six months. Other signs of vitamin B12 deficiency may include:

  • numbness, tingling, and pins and needles in the arms and legs
  • pale skin
  • unsteady walking or balance problems
  • a rapid heartbeat
  • shortness of breath
  • a swollen tongue
Low levels of stomach acid, known as hydrochloric acid (HCL), can also contribute to vitamin B12 deficiency, Dr Berg notes. He explains: “Your digestive system needs HCL to properly break down and absorb many vitamins and minerals.

“As we get older, HCL levels naturally decline. They can also drop if you take antacids or medications like Metformin. Interestingly, acid reflux can actually be a sign of low HCL, and antacids may worsen the problem. Betaine hydrochloride is one way to support normal stomach acidity.”

What Else Is Worth Being Aware Of?

Deficiencies in other nutrients may also cause symptoms that resemble dementia. Dr Berg highlights vitamin B1, which is often linked to high sugar and carbohydrate intake. Zinc deficiency, sometimes related to phytic acid found in grains, and low vitamin D levels due to limited sun exposure, may also play a role. “Nutrient deficiencies can shrink the hippocampus, which is linked to Alzheimer’s disease,” Dr Berg said.
