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.

California-based Dr. Salvador Plasencia, who supplied 20 vials of ketamine to Matthew Perry, the Friends (1994–2004) star, has been sentenced to 30 months in prison. Perry, 54, was discovered dead in his luxurious Los Angeles home on October 28, 2023. The actor had a history of depression and substance use but was reportedly on the path to recovery. His final on-screen appearance was playing himself in the 2021 feature-length special, *Friends: The Reunion*.

Perry accidentally drowned due to the acute effects of a ketamine overdose. Five individuals faced charges in the case, all of whom eventually pleaded guilty. Dr. Plasencia is the first person to be sentenced in connection with Perry’s death. In addition to his 30-month prison term, he was ordered to pay a fine of $5,600. But what exactly is ketamine, and how can an overdose affect the body?

Doctor Who Supplied Matthew Perry Ketamine Pleads Guilty

Perry was found dead in his hot tub on October 28, 2023, at age 54. The LA County Medical Examiner determined that his death resulted from the “acute effects of ketamine,” with contributing factors including drowning and coronary artery disease. In July 2025, Dr. Plasencia pleaded guilty to felony charges for distributing ketamine to four individuals. He also confirmed that Perry had received multiple doses of the drug prior to his death. Perry’s death in Los Angeles, California, was officially attributed to the “acute effects of ketamine,” which caused him to lose consciousness and drown in his hot tub. He had struggled with substance abuse for years and had been receiving ketamine treatment for anxiety and depression at an accredited clinic, according to the BBC.

What Is Ketamine?

Ketamine is a medication used by doctors as an anesthetic to induce temporary loss of consciousness. Under the Controlled Substances Act, it is classified as a Schedule III non-narcotic substance. The FDA has approved ketamine for use only as a general anesthetic. However, in some cases, doctors prescribe it “off-label” for conditions such as depression. “Off-label” refers to using a drug for a condition that the FDA has not specifically approved.

How Does Ketamine Overdose Harm Your Body?

Certain medical conditions can make ketamine overdose riskier. People with heart disease or high blood pressure may experience increased intracranial pressure, raising the chance of stroke. Blood flow to the heart can be reduced. As a relaxant, excessive ketamine can interfere with breathing, causing it to become shallow. High doses can also be toxic to the liver and urinary bladder. Unregulated or repeated use may lead to dependence and increase the risk of developing schizophrenia.

Side Effects Of Ketamine

At prescribed doses, common side effects of ketamine, according to Medical News Today, include:

• Drowsiness
• Double vision
• Confusion
• Nausea
• Vomiting
• Dizziness
• A general feeling of unease

Ketamine can also cause a wide range of other symptoms affecting different parts of the body, though these are less frequent.

Ketamine As A Drug Of Abuse

Ketamine can produce sensations of detachment from the environment, pain relief, and hallucinations, which has led to its misuse. Recreational users often describe feelings of being separated from their body or a floating sensation. Some report near-total sensory detachment, which they compare to a near-death experience.

The drug is particularly popular among teens and young adults in club settings. Many users prefer ketamine trips to PCP or LSD because the hallucinations are shorter—lasting 30 minutes to an hour—rather than several hours.

Always consult a healthcare professional before starting, stopping, or changing any medication.

As December rolls in, familiar melodies float through malls, train stations and sometimes right outside your front door. Carol groups wrapped in tinsel bring a warm sense of nostalgia. Their voices rise in unison, cheerful and bright, filling cold evenings with a comfort that feels almost instinctive. What most people do not realize is that this seasonal tradition may be giving the singers themselves a genuine health lift.

Researchers have been exploring this for years, and their findings suggest that singing is far more than a joyful holiday hobby. It strengthens social bonds, supports emotional wellbeing and even offers physical benefits that reach deep into the brain and lungs.

Why Singing Feels So Good

Alex Street, a researcher at the Cambridge Institute for Music Therapy Research, describes singing as a cognitive, physical, emotional and social act, as reported by BBC. When people sing, especially in groups, the brain lights up in ways few other activities can replicate. Regions responsible for language, movement and emotion get activated at the same time. The steady breathing that singing requires also prompts the release of endorphins, which brings on feelings of pleasure and reduces pain.

Psychologists have long noted how even strangers can develop a sense of togetherness after singing side by side for just an hour. This may explain why community choirs often feel like extended families.

A Simple Workout with Surprising Benefits

Beyond the emotional high, singing demands more from the body than many expect. Studies have shown that it can improve heart rate, circulation and blood pressure. The controlled breathing and longer exhalations strengthen the lungs in ways similar to moderate physical activity. Some researchers even compare a singing session with a brisk walk.

BBC reports that Adam Lewis, an associate professor of respiratory physiotherapy at the University of Southampton, notes that singing encourages people to use their respiratory muscles more efficiently. This is one reason why it has become a useful complementary tool for people living with chronic lung conditions.

Healing Through Harmony

One of the most profound uses of singing is in therapy for people recovering from brain injuries or neurological illnesses. Music therapists often rely on songs from childhood to help patients regain speech or movement. The story of former US congresswoman Gabrielle Giffords is one of the most well known examples, reports BBC. After surviving a severe brain injury, she regained her speech partly through singing familiar melodies during therapy sessions.

Similar approaches have been used with stroke survivors, patients with Parkinson’s disease and people living with dementia. Singing provides repeated vocal practice, encourages focus, and stimulates both sides of the brain. Experts also believe that it may help slow cognitive decline in older adults, although long term studies are still needed.

A Gentle Way Back to Community

For many people living with chronic illness, joining a choir brings something even more meaningful than physical gains. It offers a space where patients, caregivers and professionals participate as equals. Street describes these shared moments as a rare kind of unity that dissolves labels and replaces them with a sense of belonging.

As researchers learn more about the power of song, the message becomes clearer. Singing is not just entertainment. It is a tool for connection, a low cost therapy and a way to strengthen both mind and body. So this festive season, joining a group around the Christmas tree might be more beneficial than you think.

Delhi's Air Quality Index today recorded 'severe' in several location. The Central Pollution Control Board (CPCB) data from 40 monitoring stations from across the city showed AQI above 401 at 7.05 am on Wednesday morning. City's average AQI stood at 376.

While it has only been three days into December, the AQI levels have undergone severe changes. On November 30, Delhi's AQI was recorded at 279, on December 1, it was recorded at 304, while on December 2, the AQI went up to 372.

Amid all this, Dr Ritu Singh, Director Professor and HOD, Department of Biochemistry at Lady Hardinge Medical College posted on her Instagram, what she calls the 'only steps to save your lungs in Delhi".

What Does the Doctor Say?

"If you’re living in Delhi right now, the first line of protection is simple: avoid breathing unfiltered air. If you can’t leave the city, wear an N95 mask every time you step outside or move away from a HEPA-filtered space," says Dr Ritu Singh.

The doctor points out that keeping a high quality HEPA filter at home and at your workplace is essential. She points out that though it may be expensive, but one should know that their "lungs are not replaceable". She says, "Yes, spend all your hard earned money on HEPA filters because the lung is not replaceable."

What Is HEPA Filter? How Does It Help?

As per the US Environmental Protection Agency (EPA), HEPA or also known as the high efficiency particulate air is a type of filter that can theoretically remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm). The diameter specification of 0.3 microns corresponds to the worst case; the most penetrating particle size (MPPS). Particles that are larger or smaller are trapped with even higher efficiency. Using the worst case particle size results in the worst case efficiency rating (i.e. 99.97% or better for all particle sizes).

What Else Can Be Done To Stay Safe From Air Pollution?

Dr Singh suggests that indoor plants could be added, though it could only offer a "small but meaningful improvement in air quality".

One famous NASA experiment, published in 1989, found that indoor plants can scrub the air of cancer-causing volatile organic compounds like formaldehyde and benzene.

These plants are:

• Spider Plant
• Snake Plant
• Peace Lilly
• Aloe Vera
• Boston Fern
• English Ivy
• Rubber Plant
• Golden Photos
• Bamboo Palm
• Dracaena

The doctor also recommends that one should increase their intakes of antioxidant foods. "Increase your antioxidant intake—turmeric, amla, oranges—these won’t fix pollution, but they help your body cope with oxidative stress.”

Antioxidants strengthen the immune system by fighting oxidative stress, which is caused by unstable molecules called reactive oxygen species (ROS). The body's normal processes, like breathing and metabolism, create free radicals (ROS). Antioxidants donate electrons to these unstable molecules, which neutralizes them and stops them from damaging healthy cells.

"Right now, the goal is extremely clear: prevent inhalation of polluted air. Delhi’s current levels are dangerous for the lungs, the heart, and the entire respiratory system," the doctor says.
