A woman's health is intricately linked to her menstrual cycle, which is an important sign of her overall well-being. Throughout puberty and menopause, hormonal changes affect not only fertility but also mood, energy, and long-term health. A normal cycle usually indicates balance, whereas abnormalities may suggest problems such as PCOS, endometriosis, or thyroid disease.

Our bodies do not always work in a perfect clockwork operation and unexpected vaginal bleeding can often confused us. Is it a mere spotting? A normal period? A symptom of something more concerning? Differences between spotting, menstrual bleeding, and intermenstrual bleeding should be understood is crucial for maintaining reproduction health.

Here is a short guide to help you differentiate while you are confused.

Spotting

Spotting is vaginal bleeding that doesn't happen as part of your regular menstrual period. It commonly manifests as fine droplets or smears of blood on clothing or toilet tissue. The intensity of the blood ranges from deep red (recent blood) to pink (having cervical mucus mixed in it) or brown (older, oxidized blood). Spotting is not very much and can't be seen in a way that needs either a tampon or a pad to absorb.

Common Causes of Spotting

Spotting is caused by numerous factors, and in the majority of instances, it is nothing to worry about. Some frequent causes are:

Hormonal Birth Control Transitions: New birth control technique, for instance, birth control pills, IUDs containing hormones, or implants, results in temporary spotting as the body adapts.

Ovulation Bleeding: A few individuals get spotting light around the time of ovulation as a result of hormonal changes. It normally happens in the mid-cycle and could be followed by slight cramping.

Cervical Ectropion: A harmless condition when cells from the inside of the cervical canal migrate to the outer cervix, causing the outer cervix to become more sensitive and prone to faint bleeding on coitus or physical activity.

Early Pregnancy (Implantation Bleeding): 15–25% of pregnant women experience light spotting around 10–14 days post-conception, which is confused with an early period.

When to See a Doctor

Spotting is usually harmless, but it's best to consult a doctor if:

  • It continues after a few months of initiating new birth control
  • Is accompanied by pelvic pain or abnormal discharge
  • Occurs after frequent intercourse
  • Occurs during pregnancy and is not verified as implantation bleeding

Menstrual Bleeding

There is a time, also known as a period or menstruation, when the uterine lining sheds due to changing hormone levels. It would last for approximately 2-7 days and is heavier initially. The hue and texture of period blood shift during the menstrual cycle:

Red: New active bleeding at the start of a period

Brown or dark red: Older, slower blood in leaving the uterus

Clots: It's normal to have small clots, but bigger clots may be a sign of heavy menstrual bleeding (HMB)

Why You Have a Period Essentially?

Menstruation is a part of the reproductive cycle, and it happens around every 21–35 days. When there's no pregnancy after ovulation, hormone levels fall, causing the uterine lining to be shed.

Signs Your Period May Be Abnormal

Though periods differ in different people, there are some signs that point towards probable underlying conditions:

  • Prolonged bleeding (longer than 7 days)
  • Heavy flow necessitating pad/tampon changes every 1–2 hours
  • Severe cramps that disrupt daily life
  • Irregular periods or absent periods

If you have any of these, conditions such as polycystic ovary syndrome (PCOS), endometriosis, or thyroid disease may be involved, and a medical visit is in order.

Intermenstrual Bleeding

Unlike spotting, intermenstrual bleeding is heavier and unexpected between regular periods. It may be from bright red to dark brown and can contain blood clots.

Possible Causes of Bleeding Between Periods

Sexually Transmitted Infections (STIs): Chlamydia and gonorrhea can lead to inflammation and abnormal bleeding.

Pelvic Inflammatory Disease (PID): A bacterial infection of the reproductive organs and can lead to abnormal bleeding.

Uterine Fibroids or Polyps: Benign growths in the uterus that may cause unexpected bleeding.

Endometrial Hyperplasia or Cancer: In some instances, abnormal bleeding may be a sign of abnormal cell growth in the lining of the uterus.

When to See a Doctor

See a doctor if intermenstrual bleeding is:

  • Frequent or persistent
  • Associated with pelvic pain or discomfort
  • Associated with abnormal discharge, fever or painful sex

Recognizing your body's rhythms can assist you in identifying normal versus abnormal bleeding. Monitoring your menstrual cycle through an app or calendar may flag changes that should be checked with a doctor. If you have any questions regarding abnormal bleeding, visiting your health care provider is the way to go.

Is Delhi's Toxic Air Making Your Period Cramps More Painful? Here's What Study Says

Updated Dec 19, 2025 | 01:30 PM IST

SummaryDelhi’s air quality remains in the very poor to severe range, raising fresh health concerns beyond lungs. Research shows long-term exposure to pollutants, especially PM2.5, significantly increases the risk of painful menstrual cramps. Experts warn air pollution can worsen reproductive health, hitting women and girls hardest in highly polluted urban areas.
Is Delhi's Toxic Air Leading To More Painful Cramps During Period? Here's What Study Says

Air quality in Delhi remains toxic, despite the GRAP !V measures implemented in the national capital. Today, Delhi recorded an AQI of 358, this remains under 'very poor'. As per the Central Pollution Control Board (CPCB), the AQI was recorded at 442 in Ghazipur, 409 in ITO, and 447 in Palam, all under 'severe' category.

While we have long known that pollution impacts lung and respiratory health, but it can impact beyond that, including causing severe menstrual cramps.

What Proves That Air Pollution Impacts Menstrual Cramps?

A study published in Frontiers in Public Health, explored the data of 2,96,078 women and girls between the age of 16 to 55 years in Taiwan and correlated it with the long-term air pollution data between 2000 and 2013. None of these women had any history of dysmenorrhea before the survey had began. Dysmenorrhea is a common gynaecological condition that impacts 16 to 91% of people in their reproductive age. The signs and symptoms include painful and severe periods that are results of hormonal imbalances.

The results showed that during the 13 years, 4.2% women and girls were diagnosed with dysmenorrhea for the first time. The study concluded that risk of developing dysmenorrhea was up to 33 times higher among women and girls who lived in areas with the highest levels of air pollutants.

Professor Hsu, who conducted the study said, "Our results demonstrate the major impact of the quality of air on human health in general, here specifically on the risk of dysmenorrhea in women and girls."

The pollutants in questions are nitrogen oxide, nitric oxide, nitrogen dioxide, carbon monoxide, and particle smaller than 2.5 µm in diameter (PM2.5).

How Air Pollution Shapes Menstrual Health - Its Impact

The public health impact of air pollution is more layered and gendered than it often appears. Over the years, a growing body of research has begun to link polluted air with menstrual health problems. A 2018 study found that teenage girls exposed to higher air pollution were more likely to experience irregular periods and took longer to develop regular cycles during adolescence and early adulthood. Other studies have connected air pollution with longer menstrual cycles, increased stress, reproductive health issues, and even changes observed during lockdown periods. Conditions such as infertility, metabolic syndrome, and polycystic ovary syndrome have also been associated with prolonged exposure to polluted air.

These findings challenge the idea that menstrual health is purely biological. Instead, it is deeply influenced by social and environmental conditions, including income levels and where a person lives. In the present study, researchers observed that younger women, women from lower-income backgrounds, and those living in highly urbanised areas faced a higher risk of developing dysmenorrhea or painful periods. Among all factors studied, long-term exposure to high levels of PM2.5 emerged as the strongest contributor. PM2.5 refers to fine, inhalable particles commonly found in polluted air that can penetrate deep into the body.

The concern becomes sharper in the Indian context. In 2019, India recorded the highest PM2.5 levels globally. The study highlights clear differences in menstrual experiences between women and girls living in urban versus rural areas. Those in low-income and densely populated urban regions, where exposure to air pollution is often highest, showed a significantly greater risk of dysmenorrhea.

This health burden is further compounded by period poverty, which continues to affect large sections of rural India and many other countries. Limited access to sanitary products, lack of awareness, and social stigma mean that many girls and women already miss school and work during their periods. Increased menstrual pain linked to environmental factors like air pollution only deepens these challenges.

A 2017 study underlined the importance of identifying environmental influences on the menstrual cycle from a public health perspective, noting potential long-term consequences such as infertility, reproductive cancers, osteoporosis, and metabolic disorders.

Could Bird Flu Become The Next Pandemic For Humans?

Updated Dec 19, 2025 | 11:37 AM IST

SummaryLong confined to birds, avian flu is increasingly showing signs it could infect humans. Studies from Cambridge, Glasgow and Ashoka University warn H5N1 can adapt, spread, and escalate rapidly. Simulations show early action is crucial: beyond 2–10 cases, containment becomes unlikely, raising real pandemic concerns. Global surveillance and response remain essential.

Bird flu viruses have been present for long, and what was earlier understood as a virus just limited to avian, could now affect humans too. Bird flu viruses could have a potential risk for humans and may become next pandemic. This comes from two different studies, one done by the universities of Cambridge and Glasgow that show how avian flu strains are multiplying even when the body temperatures could hinder viruses. Whereas, another important study led by Indian scientists, by Philip Cherian and Gautam Menon of Ashoka University, published in BMC Public Health predict if H5N1 or the bird flu virus, could start spreading among humans. How quickly must we act to stop it?

How Was The Study Conducted?

Using BharatSim, an open-source simulation platform originally developed during Covid-19, the researchers recreated what an outbreak might look like in real life. “The threat of an H5N1 pandemic in humans is a genuine one,” Prof Menon said, “but we can hope to forestall it through better surveillance and a more nimble public-health response.”

Their model begins where experts believe a real outbreak would: with a single human infection, most likely a poultry worker or someone exposed to infected birds at a farm or market. The danger, the researchers argue, lies not in that first case, but in whether sustained human-to-human transmission takes hold.

The Cambridge and Glasgow study also provides that the viruses generally replicates most effectively in the upper respiratory tract, where temperatures are around 33 °C. They replicate less efficiently deeper in the lungs, where temperatures rise to about 37 °C. However, avian flu thrives in hotter environments, which can read up to 40 to 42 °C.

Why Does Timing Matter More Than Anything Else?

The study by Ashoka University has the most sobering findings in how fast control can slip away. According to the simulations, once cases rise beyond roughly two to ten people, the virus is likely to move beyond immediate contacts and into the wider community.

If households of close contacts are quarantined when just two cases are detected, the outbreak can almost certainly be contained. By the time ten cases are identified, however, the model suggests the infection has probably already spread far enough that early interventions no longer make a meaningful difference.

To ground their work in reality, the researchers focused on a village in Tamil Nadu’s Namakkal district, one of India’s largest poultry hubs. With more than 1,600 farms, around 70 million chickens and tens of millions of eggs produced daily, the region reflects the kind of dense human-animal interaction where spillovers are most likely.

In the simulation, the virus spreads outward from a single workplace into homes, schools and markets, tracking primary and secondary contacts. Once “tertiary” infections, contacts of contacts, appear, control becomes dramatically harder without severe measures such as lockdowns.

What Works And What Does Not Work

Culling birds work, but only if it happens before humans are infected. Once the spillover is done, isolating patients and quarantining is the only option that can stop the virus, that too if done very early. Targeted vaccination could help raise the threshold at which the virus can sustain itself. Quarantine imposed too early keeps families together longer, increasing household transmission. Imposed too late, it barely slows the outbreak at all.

Why Is It Important To Understand How Avian Flu Works?

Avian flu, bird flu or the H5N1 is not new. It first appeared in humans in China in the late 1990s and has since become entrenched across South and South-East Asia. Most of the time, it remains a disease of birds. But every so often, it spills over.

Between 2003 and August 2025, the World Health Organization recorded 990 human infections across 25 countries. Nearly half of those infected died, a fatality rate of around 48%. The numbers are small, but the severity is striking.

In recent years, the virus has shown an unsettling ability to cross species barriers. In the United States, H5N1 has affected more than 180 million birds, spread to over 1,000 dairy herds across 18 states, and infected at least 70 people, most of them farmworkers. In India, the virus killed three tigers and a leopard at a wildlife rescue centre in Nagpur earlier this year, a reminder that mammals are increasingly getting caught in its path.

Fact Check: Are Nicotine Pouches Safer Than Smoking?

Updated Dec 19, 2025 | 07:49 AM IST

SummaryNicotine pouch use is rising in the UK, especially among young adults. UCL research shows adult use climbed from 0.1% to 1% in five years, adding 522,000 users. While less harmful than smoking, pouches are not risk-free, may affect developing brains, lack age limits, and are heavily used by young men.

Nicotine pouches have become popular in the UK, show many studies, this is especially true in the case of young adults.

In fact, a new study done by the researches from University College London (UCL) has found that in the last five years, there has been an increase from 0.1 per cent to 1 per cent of adults using nicotine pouches. This means, around 522,000 more people in the UK have started using the pouches.

How Does A Nicotine Pouch Work?

The pouches are placed between the lip and gum and it releases nicotine slowly. The pouches are also available in variety of flavors, with sweeteners and plant-based fibers. It does not contain tobacco like vapes do and usually are considered to be a healthier alternative to smoking.

Health and Me ran a fact check on whether it truly is safer than smoking, and here is what we found.

Are Nicotine Pouches Safer Than Smoking?

"This risks are substantially less than some other nicotine products like smoking, because there is no tobacco and there is no combustion," said Dr Harry Tattan-Birch, the lead author of the study, to Mornings with Ridge and Frost.

"And we know the combustion of tobacco is the thing that causes most of the diseases related to smoking," he says.

However, he and his team has warned that while it may not cause serious illness like tobacco can, young people could have a negative impact in their lungs and brains, as they are still in developing stage. This makes them more sensitive to the effects of nicotine, and it could become difficult to stop using it.

A UCL research fellow earlier told Sky News that while nicotine pouches are far less harmful than smoking, their long-term effects remain unclear because they are relatively new. Drawing on what is known about their contents, she noted they are not risk-free, as users are still exposed to some toxic substances, albeit at much lower levels.

Who Are Using These Nicotine Pouches?

Researchers from UCL, supported by Cancer Research UK, analysed survey responses from 127,793 people aged 16 and above across England, Scotland and Wales, collected between October 2020 and March 2025.

Their analysis showed that nicotine pouch use among 16 to 24-year-olds rose to 4% in 2025, up from just 0.7% in 2022. The increase was most pronounced among young men, with one in 13 men in this age group, or 7.5%, reporting use.

Overall, men accounted for 72% of nicotine pouch users between 2022 and 2025, while 47% were under the age of 25. Dr Tattan-Birch said the growth in use has been driven almost entirely by young people, particularly young men, with usage among adults over 35 remaining low and largely unchanged.

He added that this trend also includes children. Since nicotine pouches are not classified as tobacco or vape products, there are currently no age limits. Advertising is also unrestricted, allowing brightly coloured, sweet-flavoured products to appeal to younger audiences.

Do Nicotine Pouches Help Quit Smoking?

The research found that 69 per cent of pouch users were reported using other nicotine products, while 56 per cent of them smoked, as per the survey from January 2022 to March 2025.

1 in 6, which makes it 16 per cent said they never regularly smoked. "Whether nicotine pouches are good or bad for public health depends on who is using them. If it's a young person who would otherwise start smoking, then the use of pouches might help to reduce harm. However, if it's a person who otherwise would not use nicotine at all, then the potential for harm increases," said Tattan-Birch.
