Fasting may reset your body, but can it reset your mind? The new trend of dopamine fasting claims it can. And wait, there's more. This trend also works against dopamine resistance, implying that things that did not make you happier before will now do. You see, dopamine is a part of the brain's reward system and plays an important role in your pleasure reception. While this neurotransmitter is not directly linked to an individual's happiness, it triggers feelings of satisfaction, motivation and pleasure.

However, a person can also reach a stage of dopamine resistance if they continue to indulge in activities that trigger its frequent or constant release. In this case, the individual stops feeling the impact of this neurotransmitter and thus, does feel good or happy.

So does dopamine fasting work?

Dopamine fasting is a practice where individuals limit their exposure to activities or stimuli that typically provide a surge of dopamine. The idea behind dopamine fasting is to reset or recalibrate the brain's reward system. This is usually done by abstaining from gratifying things or experiences like social media, junk food, and even sex. Proponents of dopamine fasting argue that continual overstimulation from digital devices, social media, and easily accessible indulgences has numbed our brain's reward pathways. By regularly denying ourselves these dopamine triggers, the idea claims, we might restore our ability to acquire fulfilment from life's basic pleasures.

How Does Dopamine Imbalance Affect Your Mental Health?

Having low levels of dopamine can make you less motivated and excited about things. In Parkinson's disease, there is not enough dopamine in the areas of the brain important for movement. This leads to problems with muscle stiffness and movements such as walking.

The symptoms of a dopamine imbalance depend on what is causing the problem. They include physical symptoms such as:

• muscle cramps, spasms or stiffness
• digestion problems, such as constipation or reflux
• pneumonia
• trouble sleeping
• moving or speaking more slowly than usual

• feeling tired and unmotivated, or sad and lacking hope
• having low libido (sex drive)
• hallucinations (experiencing something that's not real)

How Can I Adjust My Dopamine Levels?

Adjusting dopamine levels is complicated, as it is involved in many different roles in the brain. Your doctor won't measure your dopamine levels directly, and there is no simple test to measure it. Your symptoms will be the clues that tell your doctor if you have too much or not enough dopamine. They will then prescribe medicines to adjust your dopamine level, based on your symptoms, and make adjustments based on how your body responds and how you feel.

A new review of studies has found that people living with type 2 diabetes have a significantly higher risk of developing Alzheimer's disease.

Researchers from Curtin University conducted a systematic review and meta-analysis of 40 studies. They estimated that if 1,000 people with type 2 diabetes were followed for a year, an average of 4.7 would develop Alzheimer's disease.

Published in Alzheimer's Research & Therapy, a separate analysis found that type 2 diabetes was associated with a 53% higher adjusted relative risk of Alzheimer's disease compared with people without the condition.

How Does Blood Sugar Affect Memory?

Ahead of World Diabetes Day, Dr Sudhir Kumar, neurologist at Apollo Hospitals, Hyderabad, in a post on X, explained that several overlapping mechanisms may link type 2 diabetes to Alzheimer's disease. These include:

• Brain insulin resistance: Brain cells become less responsive to insulin, potentially impairing their ability to use glucose for energy and clear amyloid and tau proteins.
• Vascular damage: High blood sugar can damage large and small blood vessels in the brain, increasing the risk of strokes and vascular dementia.
• Chronic inflammation: Peripheral inflammation and lipid abnormalities can weaken the blood-brain barrier and trigger neuroinflammation.

How Does Diabetes Increase The Risk Of Dementia?

According to Alzheimer's Society UK, diabetes is an established risk factor for dementia. The risk also increases with the duration and severity of diabetes. However, having diabetes does not mean a person will necessarily develop dementia.

With diabetes and Alzheimer's disease cases rising globally, understanding the link between the two conditions is becoming increasingly important.

Insulin helps regulate blood sugar by enabling the body's cells to use glucose for energy. In people with diabetes, the body either does not produce enough insulin or cannot use it effectively, causing blood sugar levels to rise.

Studies have linked type 2 diabetes to an increased risk of dementia. In people with type 1 diabetes, severe and repeated episodes of high or low blood sugar have also been associated with a higher risk.

Diabetes and Alzheimer's disease may share certain underlying mechanisms. In both conditions, brain cells can become less responsive to insulin, potentially affecting brain function and contributing to the accumulation of amyloid and tau proteins associated with Alzheimer's disease.

How Can People With Diabetes Protect Their Brain Health?

Dr Kumar recommended the following measures for people living with type 2 diabetes:

• Maintain blood sugar levels: Aim to keep glucose within your target range.
• Avoid extreme fluctuations: Prevent prolonged high blood sugar (HbA1c of 7% or higher) and severe, repeated episodes of low blood sugar (hypoglycemia).
• Manage other health conditions: Keep blood pressure and cholesterol under control.
• Prioritise a healthy lifestyle: Eat whole foods, including vegetables, fruits and whole grains, and engage in regular physical activity to improve insulin sensitivity.

"Early detection, consistent blood sugar management, and working closely with your healthcare team can help safeguard your cognitive future," he said.

Four-year-old Deborah started school this year full of excitement. But she is struggling to understand why she now has to attend classes on a screen. The nursery student misses the school bus, chatting with friends and running around the classroom. Despite the appeal of screens, she finds it difficult to sit still for online lessons.

Coughing badly, she asks what pollution is and pleads with her family to let her play in the park.

Deborah is not alone. Across Delhi-NCR, children are facing similar disruptions as schools shift classes online amid deteriorating air quality, keeping them indoors for longer.

Air pollution in India is no longer just a winter problem. Although levels peak during the colder months, poor air quality has increasingly become a year-round concern, with Delhi-NCR experiencing severe pollution episodes.

Beyond its well-documented respiratory and developmental effects, pollution and the disruption it brings to children's daily lives may also affect their emotional well-being. HealthandMe spoke to health experts, who warned that reduced outdoor play, disrupted social interactions and increased screen time could add to children's psychological stress.

How Air Pollution Can Affect Children's Mental Health

Air pollution should not be viewed as an isolated exposure when examining its impact on children's mental health, said Dr. Pradeep B.S., a Professor of Epidemiology and Deputy Medical Superintendent at the National Institute of Mental Health and Neuro Sciences (NIMHANS) in Bengaluru.

"Air pollution is a macro-level effect. If we reduce it to individual-level effects, we are scientifically wrong," he told HealthandMe on the sidelines of the 11th Together Against Stigma (TAS) Conference, held in the national capital.

He said air pollution is associated with several broader changes, including increased traffic, population growth, climate disturbances and unpredictable weather patterns. Together, these can have a silent effect on people's psychological well-being, including that of children and adolescents.

The effects may not always be direct. Respiratory and gastrointestinal problems, for instance, can prevent children from going outdoors and participating in activities. Losing the opportunity to play can itself become a source of distress.

He also pointed to urbanisation and road expansion, which not only contribute to pollution but also reduce green spaces, playgrounds and community recreational areas. The combination can limit children's opportunities to play, interact and socialise.

Environmental Stress Can Also Affect Children's Emotional Well-Being

Dr. Pallab K. Maulik, the Director of Research at The George Institute for Global Health India said air pollution is one of the contributors to mental health concerns, with both Indian and international research examining the association.

He told HealthandMe that pollution and environmental disasters can create anxiety and stress among children, particularly those whose everyday lives are disrupted by these conditions.

Citing an example from one of his study sites, he recalled speaking to a child living in a slum area whose home gets flooded whenever municipal tankers wash the streets. The child has to spend two days drying her books after the water enters the house.

Dr Pallaub also referred to children in the Sundarbans who regularly experience flooding and salinity-related problems.

He said some adolescents are now using platforms such as adolescent parliaments to bring their concerns to local administrators. While children are becoming more aware of environmental challenges, he said, much more needs to be done to understand how environmental changes affect their mental health.

Staying Indoors, Screen Addiction And Anxiety

Dr Syed Hubbe Ali - Health Specialist (RMNCHA) at UNICEF highlighted another possible consequence of pollution-related restrictions on outdoor activities: increased screen exposure among children and adolescents.

When children cannot go outside, they tend to spend more time indoors, often turning to mobile phones, social media and online content. This can create a cycle of screen dependence, he explained.

He described how the pursuit of dopamine, associated with the brain's reward system, can encourage children to keep scrolling through social media content.

The cycle can become more complicated when children begin posting content and seeking validation through likes and engagement.

"Once you start developing your roles, the next stage comes when you see how many likes I got. I got the likes, I don't get the likes. Then the anxiety, you know, it starts," Dr Ali told HealthandMe.

He explained that not receiving the expected engagement can cause distress and, in some cases, contribute to depressive feelings and risky behaviour.

Dr Ali also raised concerns about children spending more time on screens for online learning. Referring to an NCERT survey conducted after the COVID-19 pandemic among 3.7 lakh children, he said only 51% were able to understand online content.

He suggested that learning methods need to move beyond conventional online teaching and incorporate more games and interactive approaches to improve children's engagement.

Why Outdoor Play And Social Spaces Matter

Dr Pradeep emphasised that the impact of pollution cannot be separated from the wider changes taking place in children's surroundings.

Reduced access to green spaces and recreational areas can affect opportunities for physical activity, social interaction and play. When children are unable to participate in these activities, the effects can extend beyond physical health.

Dr Ali also highlighted the importance of outdoor activities and sunlight exposure in children's everyday lives. He said keeping children indoors for prolonged periods can increase their dependence on digital platforms as a source of entertainment and stimulation.

Gait, or an individual's walking pattern, is an important marker of overall health, reflecting neurological integrity, musculoskeletal function and cognitive status. Although walking may seem effortless, people often dismiss changes in their gait as signs of tiredness or ageing.

Losing balance while walking can sometimes be attributed to fatigue, dehydration or a momentary lapse in attention. However, recurrent or unexplained balance problems can also indicate an underlying neurological condition and should not be ignored, experts warned.

Dr Gaurav Batra, Principal Consultant, Neurosurgery, Yashoda Super Speciality, said individuals experiencing instability, changes in their walking pattern or more frequent tripping than usual should seek medical evaluation.

"Walking seems so natural that it is often taken for granted. However, it involves the brain, nerves, muscles, eyes and the balance system in the inner ear working in unison," he told HealthandMe.

"When there is a disorder in one of these systems, the way a person walks can be affected, which is exactly why the type of imbalance becomes an important consideration. One person may feel like they are being dragged in a particular direction," the expert added.

When Is Loss Of Balance A Neurological Warning Sign?

New, persistent or worsening balance problems warrant attention, Dr Batra said. Changes in walking patterns or deteriorating balance could sometimes indicate an underlying problem affecting the brain or spinal cord.

Certain conditions can cause pressure on the brain or spinal cord in the neck, resulting in subtle changes in walking patterns and the ability to maintain balance.

Dr Batra advised against dismissing increasingly abnormal changes in walking, particularly when they affect daily activities or occur alongside stiffness, tremors, weakness, numbness or difficulty with coordination.

Neurological Conditions That Can Affect Balance

Dr Atampreet Singh, Senior Director and Head, Institute of Neurosciences, ShardaCare - Healthcity, explained that disruptions in the systems responsible for maintaining balance can cause unsteadiness, difficulty walking in a straight line, frequent stumbling and an increased tendency to fall.

Recurrent balance problems may be associated with several neurological conditions, including:

• Parkinson's disease: Can affect movement and coordination, making walking and maintaining balance difficult.
• Cerebellar disorders: Can interfere with coordination and the ability to maintain a steady gait.
• Peripheral neuropathy: Damage to peripheral nerves can affect sensation and balance.
• Multiple sclerosis: Can disrupt communication between the brain and the rest of the body, affecting coordination and walking.

In older adults, recurrent or unexplained falls may sometimes be an early indication of an underlying neurological or sensory deficit, Dr Singh told HealthandMe.

Sudden Loss Of Balance Could Indicate A Stroke

A sudden loss of balance, particularly when accompanied by other neurological symptoms, can be a warning sign of stroke and requires immediate medical attention.

Dr Singh highlighted the following symptoms to watch for:

• Weakness or numbness on one side of the body
• Facial weakness
• Difficulty speaking
• Severe dizziness
• Visual disturbances
• A sudden, severe headache

Such symptoms require immediate medical assessment, the expert noted.

When Should You See A Doctor?

Seek medical attention if unsteadiness persists or worsens, particularly when accompanied by weakness or numbness in the arms or legs, frequent falls, severe headache, vomiting, changes in vision or speech, or loss of bladder or bowel control.

A doctor may conduct a neurological examination and recommend brain or spinal imaging, if necessary, to determine the cause.

The doctors noted that early diagnosis is important because some underlying conditions are treatable, and timely intervention may help prevent permanent neurological problems.

They advised patients to pay attention to when the imbalance began, whether it appeared suddenly or developed gradually, and whether it is accompanied by tremors, dizziness, numbness, weakness, speech changes or difficulty with coordination.
