Sleep changes as we age. When we were kids, we needed 10 to 12 hours of sleep, for teens it is eight to 10 and it decreases to seven to nine as we reach adulthood. But there is always a lack of urgency when it comes to sleep and young adults, many of whom prefer staying up and doing different activities. According to the Centre of Disease Control and Prevention, many national surveys show that about 37% of men, and 39% of people from the age of 45 to 64 reported not getting enough sleep.

Many people in America don't sleep the right amount. This means they either sleep too long or not long enough. But what happens to your body when you do not sleep enough? You just feel tired right? No, when you don't get this much sleep, your body can get stressed. This can make you more likely to get sick. A study published by the JAMA Network Open Sleep Trajectories and All-Cause Mortality Among Low-Income Adults showed that people who don't sleep the right amount have a higher chance of dying early. It's like your body needs that time to rest and fix itself. Without enough good sleep, things can start to go wrong. So, getting the right amount of sleep is super important for staying healthy.

How Was The Study Done?

Scientists wanted to see how sleep habits affect people's health over many years. They looked at almost 47,000 people who were between 40 and 79 years old. They asked them about their sleep habits when the study started, and then again, a few years later. The scientists wanted to see if people's sleep habits changed. They divided people into groups based on if they started with too much or too little sleep, and if their sleep changed over time. For example, some people started sleeping a lot but then started sleeping very little. This helped the scientists see how different sleep patterns affected people's health. They wanted to see the long-term effects of sleep.

The study found that people who had sleep habits that changed a lot had a higher risk of dying early. This means if you started sleeping too much and then switched to sleeping too little, or the other way around, you were more likely to die sooner. They also found that these people had a higher risk of heart problems. The risks were even higher for some groups of people, like white adults and people with higher incomes.

Sleep Deprivation And Its Effect On The Body

If you often doze off when you are sitting and reading, watching a movie, talking to someone, sitting quietly after lunch or even during a few minutes of traffic, you may be sleep deprived according to the National Heart, Lung, and Blood Institute. They explain how sleep deprivation can cause issues with learning, focusing and reacting to certain things. The symptoms of sleep deprivation in kids differ a little as they might be overly active and have trouble paying attention to certain things. If you are experiencing sleep issues, make sure to speak to a healthcare professional who will help you identify the issues and direct you towards the treatment or changes you must make. Here are some ways sleep helps your body.

Repairs Your Heart

Good sleep allows your heart and blood vessels to heal. This keeps them strong and healthy, reducing the risk of heart problems.

Controls Hunger

Sleep helps balance your hunger hormones, so you don't feel too hungry. This helps prevent eating too much and keeps your weight healthy.

Manages Blood Sugar

Proper sleep helps your body use insulin correctly. This lowers the chance of high blood sugar, which can lead to diabetes.

Supports Growth

Deep sleep releases growth hormones, helping kids and teens grow. It also repairs body tissues, which is important for everyone.

Boosts Immunity

When you sleep well, your body's defense system gets stronger. This helps you fight off germs and stay healthy.

Parkinson’s Disease is traditionally characterized by motor symptoms such as tremor and dyskinesia, although non-motor symptoms, in particular gastrointestinal (GI) symptoms such as constipation and incomplete emptying, are often the first markers of the disease and may precede the motor symptoms by years.

GI dysfunction is reported in approximately 70-80 per cent of Parkinson’s patients, mediated in large part through the gut-brain axis (GBA).

Speaking to HealthandMe, Dr Paresh Doshi, Director of Neurosurgery and Stereotactic and Functional Neurosurgery at Jaslok Hospital and Research Center, GBA, is an established two-way network that links the GI tract and the central nervous system (CNS). The connection is multifaceted, involving the vagus nerve, the enteric nervous system (ENS), the immune system, and a vast number of microbial metabolites and neuroendocrine signals.

“Constipation is seen in 66 per cent of Parkinson’s patients, attributed to disordered central and peripheral parasympathetic disruption, and can lead to alteration of the gut microbiome, which in turn worsens constipation, starting a feedback loop,” the doctor explained.

What Parkinson’s Patients Must Eat

Dr Sudhir Kumar, Neurologist at Apollo Hospitals Hyderabad, told HealthandMe that changes in the gut microbiome may influence inflammation, α-synuclein aggregation, and symptom progression.

Practical dietary principles for Parkinson’s patients include:

• Prefer fiber-rich, plant-based foods (vegetables, fruits, whole grains), which support gut microbiota
• Include fermented foods (curd, buttermilk), which may improve microbial diversity
• Reduce ultra-processed and pro-inflammatory foods
• Ensure adequate hydration (helps reduce the risk of constipation, a common non-motor symptom)
• Protein timing matters: Levodopa competes with amino acids for absorption.

These gut-targeted interventions are promising adjuncts to conventional Parkinson's therapy, and improving patient quality of life.

Parkinson’s Treatment With Dance, Art

Beyond gut-brain axis, research has proven that unconventional therapy, like dance and art, can improve Parkinson’s treatment.

A 2024 study published in the Scientific Reports found that tango, particularly Argentine tango, improved Parkinson's symptoms like thinking problems or balance issues. It also led to a significant improvement in recognizing emotions on people's faces.

Dr Kumar said dance therapy improves balance, gait, and coordination; provides rhythmic cueing, which enhances motor performance, and improves mood and motivation (dopamine-related pathways).

Similarly, art therapy has been shown to improve overall visual-cognitive skills and visual exploration strategies as well as general motor function in patients with Parkinson’s. The changes in brain connectivity highlight a functional reorganization of visual networks, as revealed by a study published in Parkinsonism & Related Disorders.

Dr Kumar said art and creative therapies are also helpful in enhancing cognitive engagement. It may help with executive function and emotional well-being and provide a non-verbal outlet for expression. However, these therapies work best as adjuncts, not replacements, to standard treatment, the expert noted.

World Parkinson’s Day 2026

World Parkinson's Day is observed annually on April 11 to raise global awareness of Parkinson’s disease, the world's fastest-growing neurodegenerative disorder.

It highlights the need for early diagnosis, research, and support for the nearly 10 million people living with the condition. The day marks the birthday of Dr. James Parkinson, who first described the disease in 1817.

The theme of World Parkinson's Day 2026 is "Bridge the Care Gap." It reflects a critical challenge that persists despite advances in medical research: many people living with Parkinson's still lack consistent access to specialist care, affordable treatment, and integrated support systems.

Parkinson's disease affected 11.9 million people in 2021 and will affect 25.2 million people globally by 2050, representing an alarming 112 per cent rise.

For most working professionals, Parkinson’s disease still feels like something that happens much later in life. It’s not something people in their 30s or even early 40s actively think about. But this scenario is changed with early onset Parkinson’s disease (EOPD). This can affect people between the ages of 21 and 50.

The problem is not just the condition itself, but how it subtly integrates into everyday life. Despite this shift, early symptoms in working professionals often go unnoticed or are misattributed to stress, fatigue, or demanding work schedules.

What Is Early-Onset Parkinson’s Disease?

Parkinson’s disease is a neurological condition that affects movement and coordination due to a reduction in dopamine-producing cells in the brain. When it occurs between the ages of 21 and 50, it is referred to as early-onset Parkinson’s disease (EOPD). In younger individuals, the condition often develops slowly and remains mild in the beginning, which makes it harder to recognize. The exact cause may involve a mix of genetic factors and environmental triggers.

Symptoms can include both movement and non-movement changes. Movement-related symptoms may involve muscle stiffness, slowed movements, mild balance issues, tremors at rest, while non-movement symptoms such as constipation, unexplained pain, sexual dysfunction, and sleep disturbances like insomnia may appear early.

In day-to-day life, these changes often show up subtly as slight hand shaking at rest, taking longer to complete routine tasks, stiffness in the neck or shoulders, a softer or less expressive voice, and disturbed sleep patterns, signs that are easy to overlook or dismiss.

What are the symptoms that working professionals may miss?

1. Symptoms Overlap With Lifestyle Issues: In fast-paced work environments, fatigue, body aches, and sleep disturbances are common. Early Parkinson’s symptoms, such as stiffness, low energy, or poor sleep, are often dismissed as burnout or long working hours.

2. Lack of Awareness in Younger Age Groups: Both patients and even healthcare providers may not immediately suspect Parkinson’s in someone in their 30s or 40s. This leads to delays in seeking medical advice and diagnosis.

3. Absence of Classic Tremors Initially: Tremors are widely recognized as a hallmark of Parkinson’s, but they may not appear in the early stages. Instead, symptoms like reduced arm swing while walking or slight slowness in movements may be present but overlooked.

4. Attribution to Mental Health or Stress: Subtle changes such as anxiety, low mood, or difficulty concentrating can be early indicators. However, these are often attributed to workplace stress rather than a neurological cause.

5. Gradual Onset of Symptoms: Parkinson’s develops slowly. Changes in handwriting, posture, or speech may happen over time, making them difficult to notice unless specifically looked for.

How Can Parkinson’s Be Diagnosed and Managed?

Because early signs are often overlooked, the condition is often recognized only when it begins to affect daily life. Diagnosis typically involves a detailed assessment along with blood tests and imaging, such as MRI, and in some cases, specialized scans like a dopamine transporter (DAT) scan may also be advised to support the diagnosis.

Management focuses on improving quality of life through physical therapy to support movement and balance, occupational therapy to make daily activities easier, and speech therapy to address communication changes. In more severe cases, deep brain stimulation (DBS) surgery may be considered to help manage symptoms more effectively.

Parkinson’s at a younger age is often easy to overlook, especially when early signs blend into everyday stress and fatigue. Paying closer attention to overall well-being can help. Staying physically active, following a balanced diet, maintaining good sleep habits, and managing stress levels all play an important role in supporting brain health. Being mindful of small but persistent changes and not brushing them off as routine can go a long way in ensuring timely attention and better long-term.

World Parkinson’s Day is observed every year on April 11 to raise awareness about the progressive, neurodegenerative movement disorder caused by the loss of dopamine-producing brain cells.

People suffering from Parkinson’s face problems in motor movement, tremors, stiffness, and impaired balance. As symptoms progress, people may have difficulty walking, talking, or completing other simple tasks.

The condition primarily affects people over 60, but is now increasingly being seen in young adults. Apart from motor loss, the disease also causes cognitive decline, depression, anxiety, and swallowing problems.

World Parkinson's Day 2026: Origin

Parkinson's Day is observed on the day that marks the birthday of James Parkinson (born in 1755). The London-based doctor was the first to describe Parkinson as a medical condition in 1817, in his famous ‘Essay on the Shaking Palsy’. In 1997, the day was officially established by the European Parkinson’s Disease Association.

World Parkinson's Day 2026: Theme

The theme of World Parkinson's Day 2026 is "Bridge the Care Gap." It reflects a critical challenge that persists despite advances in medical research: many people living with Parkinson's still lack consistent access to specialist care, affordable treatment, and integrated support systems.

The day also aims to raise awareness about neurodegenerative diseases by educating the public about Parkinson's symptoms, causes, and available care.

Global Burden of Parkinson’s

Parkinson's disease affected 11.9 million people in 2021 and will affect 25.2 million people globally by 2050, representing an alarming 112 per cent rise.

According to a 2025 study released by The BMJ, this rise is mainly due to population aging and hence ranks as one of the most rapidly growing neurological disorders based on prevalence and disability. This alarming increase necessitates immediate global health interventions, research innovation, and policy reform to counteract its effects on people and health systems globally.

In addition, lifestyle differences, genetic susceptibility, and environmental exposures can also lead to regional variation in prevalence.

What Happens To Your Brain In Parkinson's Disease?

Parkinson's Disease affects various brain regions, but the primary symptoms arise from the degeneration of neurons in the substantia nigra, a region near the brain's base. This area is crucial for producing dopamine, a chemical messenger essential for smooth and purposeful movement. Research indicates that by the time Parkinson's symptoms become evident, patients have typically lost 60 to 80% or more of these dopamine-producing neurons.

Additionally, individuals with Parkinson’s disease experience a reduction in nerve endings that produce norepinephrine, a neurotransmitter responsible for regulating many involuntary bodily functions, such as heart rate and blood pressure. This loss may account for some non-movement-related symptoms of Parkinson’s, such as fatigue and fluctuations in blood pressure.

How to Prevent Parkinson's

Though there is no cure for Parkinson's disease yet, studies indicate that some lifestyle elements have the potential to shape its incidence and progression.

• Physical Activity – Engaging in regular exercise has been linked to a reduced risk of Parkinson’s, potentially due to its neuroprotective effects.
• Diet and Nutrition – A balanced diet rich in antioxidants, omega-3 fatty acids, and plant-based nutrients may support brain health.
• Environmental Factors – Exposure to pesticides, heavy metals, and air pollution has been associated with an increased risk, suggesting a need for improved public health measures.
