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 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.
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.
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 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.
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.
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 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.
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.
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 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."
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.
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.
Stress and long working hours can worsen preeclampsia in women. (Photo credit: AI generated)
Many working women who are pregnant tend to dismiss signs such as headaches, swelling, or vision changes, thinking that they are common during pregnancy. However, these issues can be caused by preeclampsia, a serious condition that requires timely attention, especially among busy working women.
Dr Prachi Sarin Sethi, Senior Consultant – Obstetrician, Gynaecologist & Laparoscopic Surgeon, Motherhood Hospitals, Gurgaon, said, "Pregnancy comes with many physical changes, and it is common for women to experience discomfort such as swelling, fatigue, or headaches. However, sometimes these symptoms may point to something more serious, namely preeclampsia, a pregnancy-related condition that can affect both the mother and baby. Working women tend to ignore the signs of this condition and struggle in silence. Preeclampsia is a condition that usually develops after the 20th week of pregnancy. It is mainly characterised by high blood pressure and can affect organs such as the liver and kidneys. If not managed in time, it can lead to serious complications for both mother and baby."
The exact cause of preeclampsia is not known. Certain factors increase the risk, including:
Many symptoms of preeclampsia are mistaken for normal pregnancy changes. These include:
Working women may ignore these signs due to work pressure, long hours, or frequent travel, assuming they are just tired or stressed. If left untreated, preeclampsia can lead to serious complications such as:
Early detection and proper care can help manage the condition and reduce risks.
This is why working women miss the signs
In today’s fast-paced lifestyle, many women continue working through pregnancy without slowing down. Long working hours, stress, irregular meals, and lack of rest tend to worsen symptoms. Many women delay check-ups or ignore warning signs, thinking they are minor issues.
Report any signs and symptoms, such as headaches and vision changes, to a doctor. De-stress by practising yoga and meditation. Monitor blood pressure regularly, avoid overexertion, and maintain a balanced diet consisting of fresh fruits, vegetables, whole grains, and pulses. Avoid junk, oily, and canned foods. It is also necessary to stay hydrated, attend regular health check-ups, and follow-up appointments.

Osteoarthritis (OA), long considered a “wear-and-tear” disease of old age, is increasingly being diagnosed in people as young as 30, according to new research.
The review by researchers at Indraprastha Apollo Hospitals suggests OA should be viewed as a heterogeneous syndrome rather than a single disease. The condition is driven by a combination of biological, biomechanical, metabolic, genetic, and molecular factors, but in youth obesity and poor lifestyle is surging the cases.
“Osteoarthritis is no longer confined to the elderly — we are now seeing patients as young as 30, often driven by obesity and sedentary lifestyles. This research makes clear that osteoarthritis is not a single disease but a spectrum of conditions,” said Dr. (Prof.) Raju Vaishya, Senior Consultant Orthopaedic and Joint Replacement Surgeon, Indraprastha Apollo Hospitals.
Noting that a one-size-fits-all approach may not help, the expert stressed the need for personalized treatment that recognizes the specific phenotype in each patient.

The review, published in International Orthopaedics, identifies six disease subtypes, including inflammatory, metabolic, and pain-sensitization variants. Researchers recommend MRI-based tools and biomarker panels to guide treatment decisions.
Emerging technologies such as AI-assisted MRI scoring and PET-MRI with 18F-NaF may also enable earlier detection and better patient classification, although wider clinical adoption will require standardized protocols and large-scale validation studies.
More than 500 million people worldwide live with osteoarthritis, accounting for 7.6 per cent of the global population. According to Global Burden of Disease estimates, prevalence has increased by 132 per cent over the past 30 years and is projected to rise by another 60 per cent by 2050.
Women, people with obesity, and those with previous joint injuries are disproportionately affected.

Osteoarthritis occurs when the cartilage that cushions the ends of bones gradually wears down, causing joints to become stiff, painful, and less mobile.
The disease commonly affects the knees, hips, and small joints of the hands, although it can occur in almost any joint.
Common symptoms include:
Experts say maintaining a healthy weight, staying physically active, avoiding prolonged sedentary behaviour, and preventing joint injuries can help lower the risk of osteoarthritis.
One of the biggest challenges in osteoarthritis treatment is the “care gap.” Many patients are too young or not yet severe enough for surgery but may spend years relying on medications that relieve symptoms without addressing the underlying mechanics of joint stress.
Research suggest gait retraining — adjusting the way a person walks — could help bridge this gap. Unlike medication or surgery, gait retraining is non-invasive and may offer a sustainable long-term solution.
Currently, gait retraining often requires specialized tools such as motion-capture systems and pressure-sensitive treadmills. However, newer approaches, including smartphone-based video analysis and sensor-equipped “smart shoes,” are being developed to make the technique more accessible.
Experts caution against making major changes to walking patterns without professional guidance, as improper adjustments may place additional strain on other parts of the body.
Smoking is the most important risk factor for mouth cancer. (Photo credit: AI generated)
After the COVID-19 pandemic, a large number of young adults returned to social life with unhealthy coping habits such as smoking, vaping, alcohol consumption, late-night eating, and excessive spicy or junk food intake. These are now causing a worrisome surge in cases of mouth cancer in people below 40. Youngsters fail to pay attention to the early warning signs, such as unhealed mouth ulcers, a burning sensation, white patches, difficulty swallowing, or persistent mouth pain, leading to delayed diagnosis. Hence, it is the need of the hour to seek timely treatment, which can save lives.
Mouth cancer, also known as oral cancer, refers to the abnormal growth of malignant cells in the gums, lips, tongue, or the inner lining of the cheeks and floor of the mouth. Early detection of this disease can help improve survival rates. The symptoms of mouth cancer are:
According to doctors, mouth cancer can happen to anyone. But there are some risk factors that can make you more prone to developing the tumour:
For timely detection, it is important to go for regular check-ups. If any of the symptoms appear, a biopsy can help with cancer detection.
Dr Prathamesh Pai, Senior Consultant Head and Neck Surgical Oncologist, Gleneagles Hospital, Parel, Mumbai, said, “There is a spike in cases of mouth cancer among younger individuals aged 25–40. The causes can be smoking, vaping, alcohol intake, poor dietary habits, and spicy junk food. Many youngsters believe mouth ulcers are common and harmless, but any ulcer that does not heal within two weeks should never be ignored. Early symptoms may include mouth pain, white or red patches, bleeding, difficulty chewing, bad breath, or swelling inside the mouth. Also, there is a lack of dental hygiene, and almost no one visits the dentist on a regular basis. In a week, three out of five patients visiting our clinic come with signs of unhealed mouth ulcers, white and red patches, difficulty opening the mouth, or altered speech and swallowing, and are often diagnosed with mouth cancer.”
Tobacco in any form, including vaping, can damage the body from the oral cavity to the lungs, as well as the heart, urinary bladder, and brain. Combined with alcohol, the incidence of cancer rises threefold. Maintaining good oral hygiene, avoiding tobacco and alcohol, reducing spicy processed food intake, and undergoing regular dental or oral check-ups are key to preventing mouth cancer, and early detection can lead to a cure.
