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.

American stand-up comedian and actress Amy Schumer has opened up on her colonoscopy procedure didn’t go quite as planned.

Speaking at the Not Skinny But Not Fat podcast, the 44-year-old Amy Schumer stated that she’s feeling "happier than I've ever been before," but admitted that she's also been experiencing some struggles.

“I actually had kind of a botched colonoscopy, so I’m not feeling very sexual,” she noted.

Schumer, who filed for an uncontested divorce with her husband of seven years, Chris Fischer, in January, reportedly didn't share any further details.

Previously, the Trainwreck star shared major insight into her health journey over the years—including how her diagnosis with Cushing Syndrome influenced her weight loss journey.

“I didn’t lose 30lbs, I lost 50,” Amy wrote in a post on social media platform Instagram. “Not to look hot which does feel fun and temporary. I did it to survive. I had a disease that makes your face extremely puffy and can kill you but the internet caught it and that disease has cleared.”

Cushing Syndrome is a hormonal condition that causes elevated levels of cortisol, and can cause death if left untreated, as per the National Library of Medicine.

Amy has also spoken of losing weight by using Mounjaro and her physical transformation via plastic surgery.

"I have been working to be pain free and I finally am," she wrote in a November Instagram post. “My endometriosis is better. My back is healing. I no longer have Cushing syndrome so my face went back to normal. I am grateful to be strong and healthy, especially for my son.”

What Is A Colonoscopy?

A colonoscopy is a 15 to 60 minute medical procedure that is used to examine the entire inner lining of the large intestine, which includes rectum and colon for abnormalities, such as polyps, inflammation, or cancer.

A doctor uses a colonoscope, which is a thin, flexible tube with a camera to take images, remove polyps, or take issue samples.

Most health experts, including federal guidelines and the American Cancer Society, recommend that people at average risk for colorectal cancer start screening at age 45. This usually means getting a colonoscopy once every 10 years, or opting for stool-based tests every one to three years. These guidelines also play a role in whether insurance companies cover the tests.

Even so, most cases of colon cancer are still diagnosed in people over 50. What’s worrying, though, is the steady rise in cases among younger adults in their 20s, 30s and 40s over the past few decades.

Access to colonoscopies remains a concern, especially in low and middle income countries. Further, screening rates among younger eligible adults remain low. Only about one in five people aged 44 to 49 are up to date with recommended screenings.

Experts say that if the screening age were lowered further, participation might drop even more. For now, the focus remains on improving awareness and encouraging those already eligible to get screened on time.

Feeling anxious, unable to perform well, and feeling burnt out at the workplace is a common problem facing employees slogging for over nine hours every day. But now, a study suggests that taking short vacations every two months can help reduce stress accumulation.

In a 2025 research paper titled “Maximizing Recovery: The Superiority of Frequent Vacations”, Selvaraj Giridharan from the Oncology Department at Tawam Hospital in Abu Dhabi suggests that taking short breaks can help improve mental well-being and boost work performance.

The study argued that instead of a long annual vacation, frequent short breaks are often more effective and help people mentally detach from work. This also helps them recover from burnout faster.

Researchers also found that the positive effects of vacations usually fade within a few weeks after returning to work, making regular breaks important for maintaining emotional balance and productivity.

"We emphasize how regular vacations facilitate recovery and enhance well-being, thereby reducing stress and improving performance. We advocate the integration of frequent breaks into workplace culture through practical strategies for both individuals and organizations," wrote study author Selvaraj Giridharan.

Long Working Hours Can Take A Toll On Mental Health

Amid discussions around 70-hour work weeks advocated by industrialists like Narayana Murthy, the study comes as a breather.

The researchers, including experts from the National Health Service, stressed that sustained work-related stress causes significant psychobiological strain. This depletes physiological and psychological resources, manifesting as elevated cortisol levels, cognitive fatigue, and emotional exhaustion.

Without periodic recovery, this strain accumulates, increasing the risk of burnout, reduced productivity, and adverse health outcomes. India has seen several recent cases where workplace stress has affected people’s mental health, with some collapsing at work while others resorted to suicide.

Vacations Linked To Better Mood, Sleep, And Heart Health

The paper cited a meta-analysis of 22 studies that showed that vacations provide substantial psychological, physiological, and cognitive benefits.

It noted post-vacation reductions in exhaustion, improvements in mood, and increases in life satisfaction among employees.

The findings were found consistent with several studies which identified physiological improvements, including reduced cortisol levels, enhanced heart rate variability, and better sleep quality. These outcomes reflect mitigation of the physiological burden of chronic stress and position vacations as vital health interventions.

The researcher stated that vacations are essential for mitigating the psychobiological impacts of contemporary work and providing psychological, physiological, and cognitive advantages.

Although the duration of vacations is significant, frequent and shorter vacations are more effective in maintaining well-being through regular recovery, they said.

"This evidence-based perspective, rooted in effort-recovery theory, advocates strategic vacation planning by organisations and policymakers to prioritise workforce health. Societies should promote vacation policies that emphasise frequency in order to enhance employee well-being and performance,” the paper said.

In India, poor reproductive health awareness remains one of the most overlooked gaps in women’s healthcare. Many women continue to ignore gynecological symptoms, assuming them to be routine, temporary, or too embarrassing to discuss.

Persistent vaginal infections, irregular bleeding, untreated hormonal disorders, chronic pelvic pain, or recurring inflammation are often dismissed until they become severe. In some cases, these untreated or undiagnosed conditions can silently contribute to long-term health risks, including certain cancers.

The Problem With Partial Awareness

Today, many women have heard of conditions like PCOS, endometriosis, or fibroids. But awareness is often incomplete. Women may know the name of a condition, yet not know its warning signs, complications, or when medical attention is necessary.

For example, prolonged hormonal imbalance, obesity, irregular periods, and chronic inflammation may increase the risk of certain gynecological cancers over time. Similarly, lack of awareness about HPV, cervical screening, and vaccination continues to delay prevention and early diagnosis of cervical cancer.

Fertility awareness is another important gap. Many women are not familiar with their menstrual cycle, ovulation pattern, or normal reproductive changes. When women do not know what is normal for their own body, it becomes harder to recognize when something is wrong.

Social media has added another layer to this problem. While it has improved access to health information, it has also created confusion. Quick tips, unverified remedies, and incomplete advice can delay proper diagnosis and treatment.

The Knowledge Gap That Matters

Reproductive literacy is not just about knowing symptoms. It means understanding one’s body, menstrual cycle, sexual health, fertility, contraception, screening options, vaccination, and access to safe healthcare.

Unfortunately, stigma around sexual and reproductive health still prevents many women from seeking timely care. Symptoms such as abnormal discharge, bleeding after intercourse, pelvic pain, or irregular bleeding are often hidden out of fear, shame, or hesitation.

This delay is especially dangerous in cancers such as cervical, uterine, ovarian, and vaginal cancers, where early evaluation can make a major difference.
