Cold sores are a common and often frustrating skin issue. While they may look like harmless blisters, cold sores are actually caused by the herpes simplex virus (HSV).

What Causes Cold Sores?

Cold sores are caused by the herpes simplex virus (HSV), which comes in two types: HSV-1 and HSV-2.

HSV-1 is the primary cause of cold sores, usually appearing around the mouth.

HSV-2 generally causes genital herpes but can also lead to cold sores.

While the appearance of cold sores caused by both HSV-1 and HSV-2 can look similar, their locations tend to differ. However, it is possible for HSV-1 to cause sores on the genitals and for HSV-2 to appear on the mouth.

How Do Cold Sores Spread?

Cold sores are highly contagious and can spread easily. The virus can be passed on through:

• Kissing or skin contact
• Sharing food, drinks, or cosmetics (such as lip balm)
• Oral sex, which can spread both cold sores and genital herpes

Even when a cold sore isn’t visible, the virus can still be spread through close contact. This makes prevention and management key to reducing outbreaks and the risk of infecting others.

Once someone contracts HSV, it stays in the body for life. While the virus remains dormant most of the time, it can reactivate and cause new sores, especially during periods of:

• Stress
• Illness
• A weakened immune system

Unfortunately, there’s no cure for the herpes virus, but the symptoms can be managed.

Symptoms of Cold Sores

Cold sores don’t just appear out of nowhere. Before the sore is visible, you may notice a tingling or burning sensation around the lips or face, which can occur several days before the sore forms. This is the best time to begin treatment to shorten the outbreak.

When a cold sore does appear, it often looks like a red, raised blister filled with fluid. The blister can be painful to touch, and there may be more than one. Cold sores usually last around two weeks and are contagious until they crust over and heal.

The Five Stages of a Cold Sore

Cold sores go through distinct stages as they develop and heal:

• Tingling and itching: You may feel these symptoms about 24 hours before the blister appears.
• Blisters: Small, fluid-filled blisters form, typically around the mouth.
• Bursting: The blisters burst and form painful sores.
• Scabbing: The sores dry out, scab over, and may itch or crack.
• Healing: The scab falls off, and the cold sore heals.

Risk Factors for Cold Sores

Certain factors can trigger the reactivation of HSV, leading to cold sores. These include:

• Infection, fever, or cold
• Sun exposure
• Stress
• Menstruation
• Dental work or injury
• Weakened immune system due to conditions like HIV/AIDS, eczema, or chemotherapy

Managing and Treating Cold Sores

There’s no cure for cold sores, but several treatments can ease the symptoms and help manage outbreaks.

Topical Ointments and Creams

Over-the-counter antiviral creams like docosanol (Abreva) or prescription ointments like penciclovir (Denavir) can help reduce the duration of an outbreak, especially if applied at the first sign of a cold sore.

Oral Medications

Prescription antiviral medications like acyclovir, valacyclovir, and famciclovir can also help, particularly for people who have frequent or severe outbreaks. Your doctor may recommend taking these medications regularly to prevent future outbreaks.

Home Remedies

There are also some home remedies that may provide relief, such as:

• Applying ice or a cold washcloth to the sore
• Using aloe vera gel or lemon balm lip balms
• Applying petroleum jelly to ease discomfort

Canker Sores vs. Cold Sores: What's the Difference?

While cold sores and canker sores may seem similar, they are quite different:

Cold sores are caused by the herpes virus, appear around the mouth, and are contagious.

Canker sores are not contagious and appear as ulcers inside the mouth or throat.

Preventing the Spread of Cold Sores

To avoid spreading cold sores:

• Wash your hands frequently
• Avoid close contact with others during an outbreak
• Don’t share food, drinks, or personal items like lip balm

Cold sores can be a persistent issue, but with proper care and management, you can reduce the frequency of outbreaks and prevent spreading the virus to others.

From being a macho dude, Bruce Willis’ personality has changed to becoming more ‘tender’ even as the 71-year-old action hero continues to battle dementia, according to his daughter Rumer.

“I’m so grateful I get to go see him,” Rumer, 37, said during a podcast interview. “Even though it’s different now, I’m so grateful.”

“There’s a sweetness. He’s always been this kind of macho dude, and there’s like a — fragile is not the right word, but — just a tenderness that maybe being Bruce Willis might not have allowed him in a certain way,” she added.

Bruce Willis is continuing into his third year living with the condition.

In March 2022, Bruce Willis, the media legend who dominated Hollywood in his prime, was diagnosed with dementia, and since then, his family has been sharing their struggle with his diagnosis and how slowly it has been taking a toll on his health.

The following year, his diagnosis was confirmed as frontotemporal dementia (FTD), which is a degenerative disease that slowly chips away at your motor skills, communication skills, etc. His wife, Emma Heming Willis, noted early signs were subtle changes in his speech, initially mistaken for a resurgence of his childhood stutter.

Rumer is the eldest daughter of Bruce and The Substance star Demi Moore, who were married from 1987 to 2000. The former couple also had Scout Willis, 34, and Tallulah, 32, together.

Although FTD is considered to be one of the rarest forms of dementia, Rumer said the disease is more “prevalent” than she realized.

“It’s wild to me. So many people come up to me now, and they say, ‘My uncle had FTD. My dad had this,” she said.

Earlier this year, in March, a hoax news of Bruce Willis’ death circulated. However, his representatives confirmed that the news is fabricated and that the actor is alive.

"He joins the long list of celebrities who have been victimized by this hoax. He's still alive and well. Stop believing what you see on the Internet," his official representative stated.

What Is Frontotemporal Dementia?

Frontotemporal dementia is a less prevalent type of dementia that mainly occurs in the frontal and temporal lobes of the brain. It tends to affect behavior, personality, language, and movement more than memory, particularly in its initial stages.

In contrast to Alzheimer's, which generally strikes older individuals, FTD can hit at an earlier age—sometimes as young as 40. The symptoms can range from changes in personality, emotional flatness, or the inability to show empathy to impulsiveness, so it is especially hard for spouses and children to cope.

The Mayo Clinic states that the symptoms of FTD vary depending on the most affected part of the brain. The progression is gradual but relentless.

Behavioral symptoms:

• Socially inappropriate behavior.
• Loss of empathy and sensitivity to others.
• Poor judgment and impulsivity.
• Apathy that can be mistaken for depression.
• Compulsive habits such as tapping, clapping, or repetitive lip-smacking.
• Decline in hygiene.
• Odd eating habits – from sudden sugar cravings to chewing on non-food items.

• Trouble understanding and producing speech.
• Difficulty finding the right words.
• Using vague terms like “it” instead of specific words.
• Simplified, telegraphic speech.
• Errors in building sentences.

• Tremors, stiffness, or muscle spasms.
• Difficulty swallowing or weakness.
• Poor balance leading to falls.
• Inappropriate emotional outbursts, such as laughing or crying.
• The “wide-based gait” noted by Dr. Gartner falls into this movement-related cluster, aligning with the suspicion of FTD.

Even as injectable aesthetic procedures are gaining popularity as "cosmetic" treatments in beauty clinics and wellness centers across the country, the Central Drugs Standard Control Organisation (CDSCO) has tightened rules around cosmetic use.

In a new public notice issued this week, the CDSCO stated that cosmetic products that come in injectable form do not fall under the definition of cosmetics under the law. It said that such products are not permitted for use by consumers, professionals, or aesthetic clinics.

"Cosmetic means any article intended to be rubbed, poured, sprinkled or sprayed on, or introduced into, or otherwise applied to, the human body," the notice said.

It added that cosmetics are for "cleansing, beautifying, promoting attractiveness, or altering the appearance."

Thus, "products supplied in the form of injectable preparation do not fall under the definition of cosmetics. No cosmetic is permitted to be used as injection by consumer/professionals/aesthetic clinics," the notice added.

What Can No Longer Be Done

The new rules bar professionals and stakeholders from using or manufacturing any cosmetic product intended for injection or medical purposes.

The move also seeks to curb misleading advertising and unauthorised cosmetic practices by clinics and individuals.

The regulator also warned against misleading claims and the use of prohibited ingredients in cosmetic products, saying such violations attract action under the Drugs and Cosmetics Act and Cosmetics Rules, 2020.

"Use of prohibited ingredients in cosmetic products, misleading claims on label, use of cosmetics for treatment, and application of cosmetics through injection attracts violations of the said Act & Rules," the notice said.

The regulator stated that no person shall alter, obliterate, or deface any inscription made by the manufacturer on the container or label of the product intended for use as a cosmetic.

The notice added that the list of generally not recognised as safe (GNRAS) and restricted ingredients is published by the Bureau of Indian Standards (BIS).

It has also encouraged the public and users to report any instance of misleading claims or violations through email and state licensing authorities.

Why Injectable Beauty Clinic Therapies Are Under Scanner

The move follows several incidents of sub-standard cosmetic products found to be sold in the market, ranging from Botox parties in upscale salons to glutathione “skin whitening” drips offered in local aesthetic clinics.

Social media trends, celebrity endorsements, and growing demand for “preventive anti-ageing” treatments among younger consumers have driven the market for injectable beauty products, especially Glutathione drips, as well as detoxifying therapies, in the country.

Medical experts have also been raising concerns over their long-term safety and efficacy. As per experts, unregulated injectable procedures carry risks ranging from allergic reactions and infections to liver and kidney complications in extreme cases.

The new norms, thus, are part of the government's plans to strengthen the regulatory mechanism for cosmetics.

The government is also reportedly planning to designate a Central Cosmetics Laboratory to test cosmetic samples and may also designate any laboratory under its control for testing, according to Mint.

In addition, manufacturers will have to keep details and records of each batch and raw materials. Records are to be maintained for three years after the expiry of each batch. Imported cosmetic products shall bear a code number as approved by the State Licensing Authority.

Amid continuing heatwave conditions in northern India, prolonged exposure to extreme temperatures can trigger serious and potentially fatal medical emergencies, particularly among elderly individuals and cardiac patients, according to an expert.

The India Meteorological Department (IMD) has warned of severe temperatures across several states.

"Heat wave to severe heat wave conditions likely to continue to prevail over northwest & central India during the week and over East India during the next 5 days," the IMD said, in its latest update on May 20.

It added that severe heat conditions will persist for at least the next 72 hours across Delhi-NCR, Rajasthan, Uttar Pradesh, Punjab, and Haryana. Temperatures in several cities are expected to touch 47°C to 48°C, with Banda currently emerging as the hottest place in the country.

Dr. Vaibhav Mishra, Senior Director & Head, CTVS, Max Super Speciality Hospital, told HealthandMe that heat-related illnesses are not limited to discomfort or dehydration alone, and can rapidly worsen if early warning signs are ignored.

There are two major heat-related illnesses that people must understand so that timely precautions can be taken — heat exhaustion and heat stroke.

"Heat exhaustion is a milder and more common condition and typically occurs after prolonged exposure to high temperatures or intense physical activity in the outdoors," Dr. Vaibhav said.

Excessive sweating leads to significant loss of water and salts from the body, resulting in:

• dehydration,
• fatigue,
• dizziness,
• muscle cramps,
• weakness,
• headache,
• nausea.

"However, if heat exposure continues and the body’s cooling mechanisms begin to fail, the condition can progress to heat stroke, which is a medical emergency. In heat stroke, body temperature often rises above 104°F," Dr Vaibhav told HealthandMe.

What may initially appear as confusion, disorientation, or irrelevant talking can rapidly worsen into:

• altered consciousness,
• seizures,
• coma,
• death.

How Heat Affects The Heart

Dr Vaibhav said that to cool the body during extreme heat, the heart has to work harder and beat faster so that more blood can be directed towards the skin for heat dissipation.

"This places additional stress on an already weakened heart. Many cardiac patients are also on medications such as diuretics, which increase fluid loss and dehydration. Certain blood pressure medicines may blunt the body’s normal response to heat and delay warning symptoms," the expert told HealthandMe.

Dehydration further thickens the blood and, combined with increased cardiac workload, can significantly raise the risk of heart attacks, strokes, and dangerous rhythm disturbances.

How To Prevent Heat Stroke

Dr. Vaibhav stressed the critical need for early recognition of symptoms, especially in vulnerable individuals such as elderly people and cardiac patients, who are much more susceptible to heat-related complications.

Simple preventive measures can save lives. These include

• avoiding direct sun exposure during peak afternoon hours,
• maintaining adequate hydration,
• wearing loose cotton clothing,
• avoiding strenuous outdoor activity,
• never ignoring early symptoms such as excessive fatigue, dizziness, or confusion.
