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.

Insufficient sleep can impact the brain. A good night's sleep allows the brain to repair and even recharge. Poor sleep over time can increase the risk of several neurological disorders and affect overall brain health.

This article helps to understand how poor sleep can take a toll on neurological health. Read on to know more about this and get a sound sleep at night.

Currently, due to hectic schedules, people are now sacrificing sleep to meet work deadlines, study longer, or spend more time on screens. Missing a few hours of sleep once in 2-3 months is harmless.

However, chronic sleep deprivation can not only cause irritation and weight gain but also neurological issues. During sleep, the brain processes memories, repairs nerve cells, regulates emotions, and clears waste products that accumulate throughout the day.

When sleep is disturbed on a regular basis, there can be a risk of neurological problems over time.

If you are one of those who is unable to get a sound sleep at night, then beware. If you are a night owl, then you will have to ensure you sleep well now.

Sleep helps the brain store and organise new information. Lack of sleep can make it difficult to concentrate, learn new skills, and remember important details. Many will also experience poor decision-making.

Poor sleep, especially when associated with conditions like sleep apnoea, can increase blood pressure and reduce oxygen supply, raising the risk of stroke in the near future.

Long-term sleep deprivation may reduce the brain's ability to clear harmful proteins such as beta-amyloid, which are linked to Alzheimer's disease and other forms of dementia.

People who sleep too little or have poor-quality sleep can also suffer from constant headaches and migraine attacks. In people living with epilepsy, inadequate sleep is a common trigger for seizures. Poor sleep increases the risk of anxiety, depression, irritability, and emotional stress.

Tips For Better Brain Health Through Sleep

It is necessary to get at least 7-9 hours of sleep per day. Maintain a consistent sleep and wake-up schedule.

Avoid screens, caffeine, and heavy meals before hitting the sack. Exercise regularly but avoid intense workouts late at night.

Keep your bedroom quiet, cool, and dark so that you can sleep better. Seek help from the doctor if you snore loudly, stop breathing during sleep, or feel excessively sleepy during the day.

So, just like a balanced diet, exercise, and staying stress-free by doing yoga and meditation, getting a good night’s sleep is also important. Sleep well and prevent any neurological issues.

In today's fast-paced world, stress has become an unavoidable part of life. While short-term stress can help us stay alert and respond to challenges, prolonged or chronic stress can have a significant impact on brain health.

On the occasion of World Brain Day, it is important to raise awareness about how unmanaged stress can silently affect memory, concentration, emotional well-being, and overall quality of life.

How Chronic Stress Affects the Brain

When the body is under constant stress, it releases higher levels of cortisol, commonly known as the stress hormone. Persistently elevated cortisol can interfere with the normal functioning of the brain, particularly areas responsible for learning, memory, and decision-making.

Individuals may experience forgetfulness, difficulty concentrating, reduced productivity, irritability, anxiety, and disturbed sleep. If left unaddressed, chronic stress may also increase the risk of depression and other mental health disorders.

How to Protect Your Brain from Stress

The good news is that the brain has an incredible ability to recover when stress is managed effectively. Adopting healthy lifestyle habits such as regular physical activity, adequate sleep, mindfulness practices, balanced nutrition, and maintaining meaningful social connections can significantly reduce stress levels and protect brain function. It is equally important to recognize when stress becomes overwhelming and seek timely professional support.

Prioritize Brain Health

Brain health is just as important as heart health, and taking care of our mental well-being should never be overlooked. This World Brain Day, let us prioritize stress management as an essential part of a healthy lifestyle. By identifying the early signs of chronic stress and making positive lifestyle changes, we can preserve memory, improve focus, enhance emotional resilience, and ensure a healthier brain for years to come.

Aspartame, Saccharin, Erythritol Linked To Faster Brain Ageing: Study

Updated Jul 21, 2026 | 02:46 PM IST

SummaryPeople with the highest total intake of sweeteners experienced a 62% faster decline in overall thinking and memory abilities than those with the lowest intake. This difference was estimated to be comparable to about 1.6 additional years of brain ageing.

White sugar is widely known for its harmful effects on health. As a result, many people—especially those with Type 2 diabetes—turn to low- and no-calorie sweeteners such as aspartame, saccharin, and erythritol, believing they are a healthier alternative.

However, a new study published in Neurology, the medical journal of the American Academy of Neurology, has again suggested that higher consumption of certain artificial sweeteners may be associated with faster declines in memory and thinking skills over time.

The researchers stressed that the findings do not prove these sweeteners cause cognitive decline. Instead, they show an association, meaning other factors could also contribute to the observed pattern.

"Low- and no-calorie sweeteners are often seen as a healthy alternative to sugar. However, our findings suggest certain sweeteners may have negative effects on brain health over time," said study author Claudia Kimie Suemoto from the University of São Paulo, Brazil.

What Did the Study Find?

The study followed 12,772 adults in Brazil, with an average age of 52 years, for approximately eight years. Researchers examined the intake of seven commonly used low- and no-calorie sweeteners:

  • Aspartame
  • Saccharin
  • Acesulfame K
  • Erythritol
  • Xylitol
  • Sorbitol
  • Tagatose

These sweeteners are commonly found in ultra-processed foods and beverages, including flavored water, soft drinks, energy drinks, yoghurt, desserts, and products marketed as low-calorie. Many are also sold separately for use in coffee, tea, cooking, and baking.

The researchers found that people with the highest total intake of sweeteners experienced a 62% faster decline in overall thinking and memory abilities than those with the lowest intake. This difference was estimated to be comparable to about 1.6 additional years of brain ageing.

Participants in the middle consumption group also showed a 35% faster decline, equivalent to approximately 1.3 additional years of ageing.

The association was especially strong among people with diabetes, who are more likely to use artificial sweeteners as sugar substitutes.

Stronger Link in Adults Under 60

Age also appeared to influence the findings. Among participants younger than 60, those who consumed the highest amounts of sweeteners experienced faster declines in verbal fluency and overall cognitive performance than those with the lowest intake.

Researchers did not observe the same association among participants aged 60 years and older. The study found that aspartame, saccharin, acesulfame K, erythritol, sorbitol, and xylitol were associated with faster declines in overall cognition, particularly memory. Tagatose was the only sweetener not linked to cognitive decline.

"While we found links to cognitive decline for middle-aged people both with and without diabetes, people with diabetes are more likely to use artificial sweeteners as sugar substitutes," Suemoto said. "More research is needed to confirm our findings and to investigate if other refined sugar alternatives, such as applesauce, honey, maple syrup or coconut sugar, may be effective alternatives."

Are There Any Limitations?

The researchers also acknowledged several limitations in study :

  • It did not evaluate every artificial sweetener currently used in foods and beverages, so the findings cannot be applied to all sugar substitutes.
  • Dietary intake was self-reported, meaning participants may have inaccurately remembered or estimated what they consumed.
  • The study was observational, meaning it identified an association but cannot establish that artificial sweeteners directly caused cognitive decline.
