Happiness is influenced by a complex interplay of various chemicals in our brain, particularly four key neurotransmitters, D.O.S.E or Dopamine, Oxytocin, Serotonin, and Endorphins. These chemicals, often referred to as "happiness chemicals," are responsible for creating feelings of joy, motivation, connection, and calm.

However, when there's a deficiency in any of these, it can significantly affect our mood, energy, and overall well-being. Let’s dive into what these four neurotransmitters are, how their deficiency impacts us, and how we can boost their levels naturally.

Dopamine: The Motivation and Reward Chemical

Dopamine is often called the "motivation molecule." It plays a major role in enabling motivation, learning, and the pleasure-reward system in the brain. When we accomplish something — whether it’s finishing a project, completing a workout, or achieving a goal — dopamine gives us that sense of satisfaction and determination to continue.

Deficiency Effects:

When dopamine levels are low, it can lead to procrastination, low self-esteem, lack of focus, and general fatigue. A person might feel anxious, hopeless, or experience mood swings because the brain isn’t getting the reward signals it needs.

Boosting Dopamine:

You can increase dopamine levels by setting and achieving small goals, exercising regularly, eating foods rich in L-Tyrosine (such as almonds, avocados, and eggs), and practicing mindfulness or meditation. Engaging in creative activities like writing or drawing also helps boost dopamine levels.

Oxytocin: The Bonding Chemical

Oxytocin is often referred to as the "love hormone" or "cuddle hormone" because it plays a major role in social bonding and trust. It’s released when we hug, touch, or engage in other forms of physical affection. Oxytocin fosters feelings of connection and emotional intimacy, making it essential for relationships, family bonding, and even team cooperation.

Deficiency Effects:

A lack of oxytocin can lead to feelings of loneliness, stress, anxiety, and difficulties in forming or maintaining relationships. Low oxytocin levels are associated with feelings of isolation and disconnection from others.

Boosting Oxytocin:

You can raise your oxytocin levels through physical touch, socialising, spending quality time with loved ones, and even engaging in activities like massage or listening to soothing music. Acts of kindness, such as helping others or volunteering, also help release oxytocin.

Serotonin: The Mood Stabiliser

Serotonin is responsible for feelings of well-being and contentment. It helps regulate mood, sleep, digestion, and even social behavior. People who have balanced serotonin levels often feel calm, confident, and emotionally stable. Serotonin is crucial in helping people feel valued and significant among their peers.

Deficiency Effects:

Low serotonin levels are linked to depression, low self-esteem, irritability, and mood swings. Individuals may feel overly sensitive to criticism, experience panic attacks, or struggle with social phobias when serotonin is deficient.

Boosting Serotonin:

You can boost serotonin by getting regular exercise, exposing yourself to sunlight, engaging in cold showers or massages, and practicing mindfulness. Simple activities like walking in nature, meditating, or doing yoga are also effective serotonin enhancers.

Endorphins: The Pain Reliever

Endorphins are the body’s natural painkillers. Released in response to stress, pain, or intense physical activity, they help alleviate discomfort and promote a sense of euphoria. Endorphins are what make you feel good after a workout or a hearty laugh, often referred to as the "runner's high."

Deficiency Effects:

Without enough endorphins, people may experience anxiety, depression, chronic pain, and insomnia. A deficiency in endorphins can make daily life feel overwhelming and physically draining.

Boosting Endorphins:

To boost endorphins, engage in laughter, exercise, and stretching activities. Eating spicy foods or dark chocolate can also stimulate endorphin production. Regular massage therapy and meditation are other ways to naturally elevate endorphin levels.

For decades, scientists believed the gradual loss of the Y chromosome in ageing men did not matter much. But a growing body of research now suggests otherwise. Studies show that losing the Y chromosome in blood and other tissues is linked to heart disease, cancer, Alzheimer’s disease and even shorter lifespan. The crux is simple but striking. As men age, many of their cells quietly lose the Y chromosome, and this loss may be shaping men’s health in ways we are only beginning to understand.

Aging And The Disappearing Y Chromosome

Men are born with one X and one Y chromosome. While the X carries hundreds of important genes, the Y is much smaller and contains just 51 protein coding genes. Because of this, scientists long assumed that losing the Y in some cells would not have serious consequences beyond reproduction.

However, newer genetic detection techniques tell a different story. Research shows that about 40 percent of men aged 60 have some cells that have lost the Y chromosome. By age 90, that number rises to 57 percent. Smoking and exposure to carcinogens appear to increase the likelihood of this loss.

This phenomenon, known as mosaic loss of Y, does not occur in every cell. Instead, it creates a patchwork in the body where some cells carry the Y chromosome and others do not. Once a cell loses the Y, its daughter cells also lack it. Interestingly, Y deficient cells seem to grow faster in laboratory settings, which may give them a competitive edge in tissues and even in tumors.

Why Would Losing The Y Matter?

The Y chromosome has long been viewed as mainly responsible for male sex determination and sperm production. It is also uniquely vulnerable during cell division and can be accidentally left behind and lost. Since cells can survive without it, researchers assumed it had little impact on overall health.

Yet mounting evidence challenges that assumption. Several large studies have found strong associations between loss of the Y chromosome and serious health conditions in older men. A major German study reported that men over 60 with higher levels of Y loss had an increased risk of heart attacks. Other research links Y loss to kidney disease, certain cancers and poorer cancer outcomes.

There is also evidence connecting Y loss with neurodegenerative conditions. Studies have observed a much higher frequency of Y chromosome loss in men with Alzheimer’s disease. During the COVID pandemic, researchers noted that men with Y loss appeared to have worse outcomes, raising questions about its role in immune function.

Is Y Loss Causing Disease?

Association does not automatically mean causation. It is possible that chronic illness or rapid cell turnover contributes to Y loss rather than the other way around. Some genetic studies suggest that susceptibility to losing the Y chromosome is partly inherited and tied to genes involved in cell cycle regulation and cancer risk.

However, animal research offers stronger clues. In one mouse study, scientists transplanted Y deficient blood cells into mice. The animals later developed age related problems, including weakened heart function and heart failure. This suggests the loss itself may directly contribute to disease.

A New Chapter In Men’s Health

So how can such a small chromosome have such wide ranging effects? While the Y carries relatively few genes, several of them are active in many tissues and help regulate gene activity. Some act as tumor suppressors. The Y also contains non coding genetic material that appears to influence how other genes function, including those involved in immune responses and blood cell development.

The full DNA sequence of the human Y chromosome was only completed recently. As researchers continue to decode its functions, the message for men’s health is becoming clearer. Ageing is not just about wrinkles or grey hair. At a microscopic level, the gradual disappearance of the Y chromosome may be quietly influencing heart health, brain health and cancer risk.

Understanding this process could open new doors for early detection, personalized risk assessment and targeted therapies that help men live longer and healthier lives.

First wife of singer Udit Narayan, Ranjana Narayan Jha made serious allegations against him, claiming that he forced her to get hysterectomy. She filed a police complaint earlier this week at the Women's Police Station in Supaul district, Bihar.

She accused Udit Narayan and his two brothers Sanjay Kumar Jha and Lalit Narayan Jha and his second wife Deepa Narayan of a criminal conspiracy that lead to hysterectomy - the surgical removal of uterus, without her knowledge. As per an NDTV report, "She claimed she became aware of this only years later during medical treatment."

Udit Narayan's First Wife's Allegations

As per the complaint, Udit and Ranjana were married on December 7, 1984, in a traditional Hindu ceremony. Udit then moved to Mumbai in 1985 to pursue his music career. She later learned through media that he had married another woman Deepa. As per the complaint, he continued to mislead her whenever she confronted him.

As per the complaint, in 1996, she was taken to a hospital in Delhi under the pretext of medical treatment, where, she claims that her uterus was removed without her knowledge. She said that she was compelled to file a complaint years after being ignored. "You all know that Udit Narayan ji repeatedly makes promises but does not fulfill them. He has not done anything till now, which is why I have come to the Women's Police Station. I deserve justice," she said.

"Nowadays, I am constantly unwell and need his support. But Udit Narayan is neither saying anything nor doing anything. He came to the village recently and left after making promises once again," she said, as per a Hindustan Times report.

What Is Hysterectomy?

It is the surgical removal of one's uterus and cervix. There are different kinds of hysterectomy available, which depends on the condition of the patients.

Total Hysterectomy

This removes uterus and cervix, but leaves ovaries. This means the person does not enter menopause after the surgery.

Supracervical Hysterectomy

Removing just the upper part of the uterus and leaving the cervix. This could also be when your fallopian tubes and ovaries are removed at the same time. Since, you have a cervix, you will still need Pap smears.

Total Hysterectomy With Bilateral Salpingo-oophorectomy

This is the removal of uterus, cervix, fallopian tubes and ovaries. This will start menopause immediately after the surgery.

Radical Hysterectomy With Bilateral Salpingo-oophorectomy

This is the removal of uterus, cervix, fallopian tubes, ovaries, the upper portion of your vagina, and some surrounding tissue and lymph nodes. This is done to people with cancer. Patients who get this enter menopause right after the surgery.

Lorna Luxe's Husband, 64, John Andrews passed away after a three-year-long cancer battle. On February 11, the British influencer shared a post on her Instagram. The 43-year-old wrote: "My beautiful, brave John died yesterday. I am heartbroken. We were together to the every end, at home, in our own bed and holding hands which is exactly what he wanted."

Lorna Luxe's Husband John Dies: What Happened To Him?

John, a former banker, was diagnosed with stage three cancer in 2023. He had been receiving treatment over the last three years. John's cancer also entered remission and it returned in 2024 and spread to his brain.

He underwent a surgery in 2025, however, he was back in hospital in December after a complication with his chemotherapy treatments. This led to organ failure.

In January this year, Lorna told her followers that she was "looking for a miracle" and shared that his cancer had "progressed to his other organs" and treatment was "no longer an option".

“I think he's possibly the bravest person. And I suppose at this point we're looking for a bit of a miracle and we're going to take each day as it comes,” she wrote on her post.

In her post that announced John's death, she wrote when she asked him how he was feeling, her husband responded, "Rough, but in love".

Lorna Luxe's Husband John Dies: Can Cancer Spread To Other Organs?

While John's cancer has not been specified, but the reports reveal that his cancer spread to other organs. According to National Institution of Health (NIH), US, the spreading of cancer to other parts of the body is called metastasis.

This happens when cancer cells break away from where they first formed, and travel through the blood or lymph system. This could lead to formation of new tumors in other parts of the body. Cancer can spread to anywhere in the body, however, it is common for cancer to move into your bones, liver, or lungs.

When these new tumors are found, they are made of the same cells from the original tumor. Which means, if someone has lung cancer and it spread to brain, the cells do not look like brain cancer. This means that the cancer cells in the brain is metastatic lung cancer.

Cancer cells could also be sent to lab to know the origin of the cell. Knowing the type of cancer helps in better treatment plan.

Lorna Luxe's Husband John Dies: Could Chemotherapy Lead To Organ Damage?

As per the University of Rochester Medical Center, in some cases, chemotherapy could cause permanent changes or damage to the heart, lungs, nerves, kidneys, and reproductive organs or other organs.

For instance, some anti-cancer drugs cause bladder irritation, it could result in temporary or permanent damage to kidneys or bladder. In other cases, chemotherapy could also have potential effects on nerves and muscles. Chemotherapy could also damage the chromosomes in the sperm, which could also lead to birth defects. In females, it could damage the ovaries and could result in short-term or long-term fertility issues.

Chemotherapy could also induce menopause before the correct age and could cause symptoms like hot flashes, dry vaginal tissues, sweating, and more.
