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.

In the wake of a young doctor from Chandigarh accusing a well-known private hospital of unnecessarily admitting patients to Intensive Care Units (ICUs), it is imperative to understand who truly requires critical care.

In a widely shared video posted on the social media platform Instagram, Dr Prabhleen Kaur alleged that the hospital is making the patients remain admitted in the ICU for as long as possible to mint money.

The doctor did not mention the name of the hospital. And HealthandMe could not independently verify the details and the authenticity of the post.

However, the incident reignited concerns over accountability, patient safety, and standards of care in the country.

Speaking to HealthandMe, Dr. Sachna Shetty, Consultant Emergency Medicine at Jaslok Hospital and Research Centre, said that: "ICU admissions are for patients with life-threatening conditions needing intensive support".

"This includes shock, respiratory failure, neurological emergencies, cardiac issues, and multi-organ dysfunction," the doctor added.

What Is ICU? Who Needs Critical Care?

The NHS UK explains that intensive care units (ICUs) are specialist hospital wards that provide treatment and monitoring for people who are very ill.

They're staffed with specially trained healthcare professionals and contain sophisticated monitoring equipment.

Also called critical care units (CCUs) or intensive therapy units (ITUs), it is required in cases where a person is seriously ill and requires intensive treatment and close monitoring.

Most people in an ICU have problems with one or more organs. For example, they may be unable to breathe on their own. Some common reasons include:

• a serious accident
• a serious short-term condition
• a serious infection
• a major surgery.

"ICU beds are limited, reserved for those who'll benefit most. Decisions are time-sensitive, based on triage and clinical scoring. It's about who needs advanced life support, not just who looks critical. Fair use of resources is key," the doctor added.

ICU Admissions: What India’s Guidelines Say

India’s ICU admission guidelines—issued by the Ministry of Health and Family Welfare in January 2024 — clearly defines who should and should not be admitted to an ICU. According to the guidelines:

• ICU admissions must be based on the severity of organ failure and the necessity for organ support or in anticipation of a potential deterioration in the patient's medical condition.
• Hospitals cannot admit critically ill patients in ICU in case of refusal by them and their relatives.
• ICU is not recommended in cases where there is no treatment possible or available, and if the continuation of therapy is not going to make an impact on the outcome, especially survival.
• Anyone with a living will or advanced directive against ICU care should not be admitted to ICU.
• Low priority criteria in case of a pandemic or disaster situation, where there is resource limitation, should be taken into account for keeping a patient in the ICU.
• Blood pressure, pulse rate, respiratory rate, breathing pattern, heart rate, oxygen saturation, urine output and neurological status among other parameters should be monitored in a patient awaiting an ICU bed

1. patients with altered level of consciousness,
2. hemodynamic instability,
3. need for respiratory support,
4. patients with acute illness requiring intensive monitoring
5. organ support or any medical condition or disease with anticipation of deterioration.

Guidelines For ICU Discharge Criteria In India

The guidelines stress the importance of physiological parameters returning to near-normal or baseline status.

Furthermore, reasonable resolution and stability of the acute illness that led to ICU admission are essential factors.

Patient and family agreement for ICU discharge, particularly in cases where a treatment-limiting decision or palliative care is opted for, is also highlighted.

Modern lifestyle changes are contributing towards the rising neurological problems among young adults, said health experts today on World Health Day 2026.

World Health Day is observed annually on April 7 to mark the founding day of the World Health Organization (WHO) in 1948 for public health worldwide. World Health Day 2026 will be observed under the theme “Together for health. Stand with science.”

The health experts noted that conditions such as recurrent headaches, mild weakness, strokes, and spine disorders were traditionally more common among older adults. However, modern lifestyle changes—sedentary habits, unhealthy diets, chronic stress, and increased screen time—are now driving a surge of these neurological problems among younger populations.

“The surge in neurological conditions today is not just a clinical challenge, but a reflection of how rapidly our lifestyles are evolving. We are seeing younger patients presenting with serious issues like stroke and spine disorders, conditions that were once more age-associated. This shift makes it imperative to recognize that neurological health is closely linked to everyday habits, stress, and timely medical attention,” Dr. Gaurav Sharma, Senior Consultant - Neurology, Paras Health Panchkula, told HealthandMe.

Neurological Disorders: Silent Onset

The health experts emphasized that the threat of neurological disorders is surging silently. The conditions, ranging from recurrent headaches and mild weakness to strokes and spine disorders, often show no noticeable symptoms in the early stage.

As a result, these go unnoticed until advanced stages, which makes the role of early detection and preventive care more crucial.

“Neurological disorders often progress silently, and by the time symptoms become severe, the condition may already be advanced. One of the biggest challenges we face today is the lack of awareness around subtle early signs, whether it is recurrent headaches, mild weakness, or persistent back issues, which are frequently overlooked or ignored,” Dr. Ritu Jha, Director & HOD - Neurology, Sarvodaya Hospital Sector -8, Faridabad, told HealthandMe.

Health specialists stressed the need to boost early detection, preventive care, and lifestyle modifications to protect brain and nerve health.

They called for changing the mindset from reactive to proactive care. Early identification of symptoms and prompt intervention can dramatically alter outcomes. They recommended:

• timely check-ups,
• awareness of warning signs,
• regular exercise,
• balanced nutrition,
• stress management.

Advancement In Neurological Care

With the progress in precision-driven and minimally invasive neurosurgery, we are now better equipped than ever to treat complex conditions effectively, provided patients seek care at the right time.

“Today’s advanced surgical techniques allow us to operate with greater accuracy while minimizing trauma to the patient, leading to faster recovery and improved long-term outcomes. Bridging the gap between symptom onset and specialist consultation will be key to reducing the overall burden of these conditions,” Dr. Jha said.

Over 7% Indians Engaging In Healthy Aging

A nationwide survey conducted by Local Circles, a Delhi-based community platform and citizen pulse aggregator, for World Health Day 2026, found that more than 7.3 percent of Indians are actively working on slowing aging.

The report showed that preventive healthcare has gained importance, and people are increasingly indulging in healthy practices such as lifestyle, diet, exercise, supplements, and therapy to ensure healthier, more active years.

It noted that fitness trends such as yoga, strength training, and regular physical activity, along with balanced diets rich in antioxidants, are widely promoted to maintain physical health and vitality.

Mental well-being practices, including meditation and stress management, are also being recognized as essential components of healthy aging.

Prime Minister Narendra Modi today, on the occasion of World Health Day 2026, reaffirmed his commitment to building a healthier society and nation.

The Prime Minister also extended gratitude to all healthcare workers for their tireless service to the public health.

He also urged citizens to work together to strengthen healthcare systems and prioritize the well-being of every individual.

“On World Health Day, we express our gratitude to all those who dedicate themselves tirelessly to the service of others and work towards a healthier planet,” PM Modi said in a post on the social media platform X.

“We also reaffirm our commitment to building a healthier society. Let us all keep working together to strengthen healthcare systems and prioritise the well-being of every individual,” he added.

The Ministry of Health also advised people not to ignore signs given by the body, such as

• Fatigue.
• Stress.
• Poor sleep.
• Dehydration.

Health Is Wealth

Union Health Minister JP Nadda highlighted India’s approach to healthcare, which combines “age-old wisdom with modern science, helping improve lives not just at home but across the world”.

Citing government initiatives such as Ayushman Bharat and the PM Bharatiya Janaushadhi Pariyojana, Nadda stated that the “strengthened healthcare system (is) making quality treatment more accessible, affordable, and inclusive for every citizen”.

The Health Minister also expressed "heartfelt gratitude to all doctors, nurses, and frontline workers whose dedication keeps our healthcare system strong. Let us all work together towards building a healthier and stronger nation”.

Meanwhile, Union Commerce Minister Piyush Goyal urged citizens to make investments for their health.

Calling health "the ultimate wealth”, he said: “This #WorldHealthDay, I urge everyone to take a little more time for themselves”.

The Minister also urged people to “move more, eat better, and prioritize well-being. Let’s also encourage every member of our family to stay fit by making healthier choices together as a family. A healthy Bharat begins at home”.

World Health Day 2026

World Health Day is observed annually on April 7 to mark the founding day of the World Health Organization (WHO) in 1948 for public health worldwide.

World Health Day 2026 will be observed under the theme “Together for health. Stand with science.” It highlights the role of the WHO in promoting public health, which has led to improvements in the global maternal mortality rate, falling by more than 40 percent since 2000, and a reduction of over 50 percent in deaths among children under five.

The WHO stated that science was behind every health progress, which led to improvements in global health and lives. This includes the development of

• anesthesia
• safer medicines and affordable vaccination
• screening technologies, such as electronic blood pressure monitors and mammography tools.

“Science is one of humanity’s most powerful tools for protecting and improving health,” said Tedros Adhanom Ghebreyesus, Director-General of the World Health Organization.

“People in every country live longer and healthier lives on average today than their ancestors did, thanks to the power of science. Vaccines, penicillin, germ theory, MRI machines, and the mapping of the human genome are just some of the achievements that science has delivered that have saved lives and transformed health for billions of people,” he added.

The WHO emphasized that science must continue to guide health decision-making at all levels.
