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.

Back pain was once considered a problem of ageing, heavy labour, or injury. Today, it is increasingly common among people in their 20s and early 30s. Many young Indians now walk into clinics with persistent lower back pain, neck stiffness, shooting pain down the leg, or recurrent muscle spasms—symptoms that were earlier seen more often in older adults.

Why are spine problems becoming more common?

The reasons are closely linked to the way modern life has changed. Long hours at desks, laptop use from beds or sofas, prolonged mobile phone scrolling, reduced physical activity, irregular sleep, stress, and weight gain are all placing unusual strain on the spine at a younger age.

Dr Satish Satyanarayana, Neurosurgeon, Apollo Hospitals, Bengaluru, said, "The spine is designed for movement. It depends on strong muscles, flexible joints, healthy discs, and good posture to function well. When a person sits for eight to ten hours a day, often slouched over a screen, the muscles supporting the spine become weak and tight. The discs between the vertebrae also experience uneven pressure. Over time, this can lead to chronic pain, early disc degeneration, nerve irritation, and, in some cases, slipped disc symptoms."

Posture problems among working professionals

One of the biggest contributors is poor sitting posture. Many young professionals work with rounded shoulders, forward-bent necks, and unsupported lower backs. This posture increases the load on the neck and lumbar spine. Similarly, “tech neck," caused by looking down at phones for long periods, can trigger neck pain, headaches, shoulder stiffness, and upper back discomfort.

Work-from-home habits have made the problem worse. Dining chairs, couches, beds, and low tables are not designed for long working hours. A person may feel comfortable initially, but the spine quietly absorbs the stress. By the time pain becomes persistent, the underlying muscle imbalance may already be significant.

Can lack of exercise make you prone to spine problems?

Lack of exercise is another major factor. Many young adults focus on work but neglect strength and mobility. Walking alone may not be enough if the core, hip, back, and gluteal muscles are weak. These muscle groups act like a natural brace for the spine. When they are weak, even simple activities such as bending, lifting a bag, climbing stairs, or sitting for long periods can trigger pain.

Stress also plays a role. Mental stress increases muscle tension, especially around the neck, shoulders, and lower back. Poor sleep reduces tissue recovery and increases pain sensitivity. In some people, repeated stress and inadequate rest can turn occasional discomfort into chronic pain.

Is back pain the same as posture pain?

Back pain should not always be dismissed as “posture pain." Medical evaluation is important if pain lasts more than two to three weeks, keeps returning, travels down the leg, causes numbness or weakness, worsens at night, follows an injury, or is associated with fever, unexplained weight loss, or bladder and bowel problems. These symptoms may suggest nerve compression, infection, inflammatory disease, or other serious spine conditions.

Can exercise help?

The good news is that most early spine problems are preventable and manageable. Young adults should take movement breaks every 30 to 45 minutes, set up an ergonomic workstation, keep screens at eye level, use a chair with lower back support, and avoid working from bed. Regular strengthening exercises, stretching, weight control, hydration, and good sleep are equally important.

It is better to exercise caution while undertaking heavy weightlifting, and it is certainly not advisable to do so without professional trainer supervision. It is also important to lift correctly, avoid sudden heavy gym workouts without supervision, and treat early pain seriously rather than relying repeatedly on painkillers. Pain medicines may provide temporary relief, but they do not correct the cause.

Back pain is often the body’s warning that the spine is under more stress than it can handle. The earlier young people correct their posture, improve their strength, and seek proper medical advice, the better their chances of avoiding long-term spine problems.

The brain is the main center of the body, which controls everything from movement and memory to emotions and decision-making. A headache or moment of forgetfulness can happen from time to time, but a few neuro symptoms indicate something. However, many people think of these warning symptoms as being stress, fatigue, or part of getting older.

Knowing when your brain is trying to alert you to an underlying problem makes a critical difference in diagnosis, treatment, and long-term outcomes.

What Is a Brain Tumor?

A brain tumor is an abnormal growth of cells within the brain or its surrounding tissues. Tumors can be benign (non-cancerous) or malignant (cancerous), but even benign tumors can cause serious health problems by putting pressure on critical areas of the brain. The symptoms vary depending on the tumour's size, location, and rate of growth.

Frequent And Severe Headaches A Warning Sign?

Many neuro conditions, including brain tumors, stroke, aneurysms, infections, and degenerative disorders, can initially present with subtle symptoms like headache. Not all headaches indicate the same condition.

While tension headaches are common, a sudden, intense headache that is described as the ‘worst headache of your life’ indicates conditions such as a brain hemorrhage or a brain tumor. Persistent headaches that become more frequent, change in pattern, or come with nausea or weakness should never be ignored.

Brain Tumor: Key Neuro Symptoms

Symptoms of a brain tumor can differ from person to person, but some common warning signs include:

1. Numbness or Weakness: Weakness, numbness, or reduced sensation in an arm, leg, or one side of the body may indicate that the tumor is affecting the brain's motor or sensory pathways.

2. Speech Difficulties: Slurred speech, trouble finding words, or difficulty understanding language can occur if the tumour involves regions of the brain associated with language.

3. Vision changes: Blurred vision, double vision, or sudden loss of sight are the results of neurodegenerative conditions affecting the brain or optic pathways.

4. Loss of Balance: Frequent stumbling, difficulty walking, dizziness, or trouble performing routine movements may develop when a tumor affects areas controlling balance and coordination.

5. Seizures: A seizure occurring for the first time in adulthood should never be ignored, as it can sometimes be one of the earliest signs of a brain tumor.

6. Memory and Personality Changes: Increasing forgetfulness, difficulty concentrating, confusion, or noticeable changes in mood and behavior may be warning signs that should not be overlooked.

Brain Tumor: Diagnosis And Treatment

The diagnosis of a brain tumor typically involves a detailed neuro examination followed by imaging tests such as MRI or CT scans, which help determine the tumor's location, size, and characteristics.

Treatment depends on the type and stage of the tumor, as well as the patient's overall health. Surgery is often the first line of treatment and aims to remove as much of the tumor as safely possible while preserving brain function.

Depending on the diagnosis, surgery may be followed by radiation therapy, chemotherapy, targeted therapy, or other advanced treatment approaches. Significant advancements in neurosurgical techniques, including minimally invasive and image-guided procedures, have improved both treatment precision and patient outcomes.

Many neurodegenerative disorders progress silently before showing severe symptoms. Delaying medical help reduces the treatment options and increases the risk of permanent damage. Early diagnosis allows the professional to help you before the complications become life-altering. When it comes to brain health, responding early to distress signals is the difference between recovery and irreversible consequences.

Brain tumours are often perceived as rare conditions that present dramatic symptoms. Many patients experience subtle and seemingly unrelated signs that can easily be mistaken for stress, fatigue, migraines, vision problems, or age-related changes. As a result, diagnosis is frequently delayed, allowing the tumour to progress and potentially affecting treatment outcomes.

Dr Abhiram Chandra Gabbita, neuro-oncological & skull base surgeon and senior consultant at AIG Hospital, Hyderabad, in an interview with Health and Me, listed the symptoms of a brain tumour that most patients miss.

One of the biggest challenges in brain tumour care is that symptoms vary depending on the tumour’s size, location, growth rate, and the part of the brain affected. Unlike many other diseases, there is no single symptom that definitively points to a brain tumour.

The Symptoms People Often Miss

In the early stages, symptoms can be mild and intermittent. Symptoms that warrant immediate consultation are:

1. Persistent or worsening headache, especially a morning headache or a headache accompanied by vomiting
2. First-time seizure in an adult
3. Blurred or double vision
4. Hearing changes
5. Loss of smell
6. Subtle weakness, numbness, imbalance, or clumsiness on one side
7. Difficulty speaking, word-finding problems, confusion, or memory decline
8. Personality changes, irritability, withdrawal, poor judgement, or reduced work efficiency
9. Unexplained nausea, vomiting, drowsiness, or increasing fatigue

These symptoms are often ignored or attributed to busy lifestyles, lack of sleep, or work-related stress.

As the tumour grows, symptoms may become more noticeable. Patients can develop worsening headaches, recurrent vomiting, blurred or double vision, hearing difficulties, weakness in the arms or legs, balance issues, speech difficulties, or changes in personality and behaviour.

In more advanced stages, symptoms can include seizures, significant neurological deficits, loss of coordination, confusion, severe cognitive impairment, or reduced consciousness. At this stage, the tumour may have already caused considerable pressure within the skull or affected critical brain functions.

Why Early Diagnosis Matters

Timely diagnosis can significantly influence treatment outcomes. When detected early, brain tumours are often smaller, more localised, and potentially easier to manage through surgery. Early diagnosis enables safer and more complete surgery and allows earlier access to modern targeted therapies, radiation therapy, or a combination of treatment approaches.

Early intervention can help preserve neurological function, reduce complications, improve quality of life, and increase the likelihood of favourable long-term outcomes.

Conversely, delayed diagnosis can allow a tumour to grow larger and affect critical areas of the brain, making treatment more complex and increasing the risk of permanent neurological impairment and cognitive dysfunction.

Advances in Treatment and the Importance of Timely Intervention

Brain tumour treatment has advanced significantly in recent years, enabling clinicians to diagnose and treat tumours with greater precision while preserving healthy brain tissue. Treatment options typically depend on the tumour's type, size, location, grade, and the patient's overall condition. Surgery remains the cornerstone of treatment for many brain tumours and is often complemented by radiation therapy, chemotherapy, targeted therapies, or a combination of these approaches.

Technological innovations are further enhancing surgical outcomes. Today, there are systems that allow neurosurgeons to access deep-seated brain tumours and perform precise, non-thermal tumour removal while using specialised fluorescence imaging to better visualise cancerous tissue, particularly in high-grade gliomas. Similarly, ultrasonic aspirator technology enables the safe and accurate removal of tumour tissue while preserving delicate surrounding brain structures. Neuro-endoscopic systems help facilitate safer tumour removal in a minimally invasive manner.

Awareness remains one of the most powerful tools in improving brain tumour outcomes. Recognising the early warning signs and seeking timely medical advice can make a meaningful difference in a patient's treatment journey.

Doctors encourage individuals to listen to their bodies and pay attention to symptoms that persist or worsen over time. Early recognition, accurate diagnosis, and prompt intervention can not only improve treatment success but also help patients maintain their independence, neurological function, and quality of life.

The key message is pattern and progression. Symptoms that persist, worsen, or occur in combination should not be ignored. Early diagnosis can change outcomes by allowing safer surgery, better preservation of speech, movement, vision, and cognition, earlier oncological treatment, and improved quality of life. Awareness should create action, not fear. So, spot the signs early to stop brain tumour progression early.
