A PET scan (positron emission tomography) is a type of imaging test that uses a radioactive tracer to look for changes in the function of cells and tissues. A tracer is a substance that is introduced into the body to make it easier to see certain areas or organs. The radioactive tracer used in PET scans emits positrons, which are tiny particles that collide with electrons in the body. This creates gamma rays that can be detected by a scanner and used to create images of the inside of the body. PET scans are often used to diagnose cancer because tumor cells typically have higher levels of activity than normal cells. They can also be used to check for treatment response, measure tumor size, and identify new tumors.

PET Scan is a nuclear medicine imaging test that uses a small amount of radioactive material, called a tracer, to look for disease in the body. A PET Scan can show how well organs and tissues are working. It can help find cancer, heart problems, and other diseases. A Positron Emission Tomography (PET) scan is a medical imaging test that helps physicians diagnose and treat diseases. PET scans use a small amount of radioactive material, called a tracer, to help physicians see how organs and tissues are functioning. The radioactive tracer is injected into the patient's body and travels to the organ or tissue being studied. Physicians can then see where the tracer collects on an image of the organ or tissue.

A PET scan is helpful in diagnosing cancer, heart disease, brain disorders, and other diseases. It can also help determine how well treatment is working. PET Scan is an acronym for Positron Emission Tomography. It's a type of medical imaging that uses a small amount of radioactive material to help diagnose and treat medical conditions. A PET scanner creates 3D images of the inside of the body. PET (positron emission tomography) scans use a small amount of radioactive material called a tracer to help doctors see certain areas of the body. The tracer is injected into a vein, and images are taken as it moves through the body.

PET scans are often used to find cancer because tumors absorb more of the radioactive material than normal tissue does. PET scans can also be used to measure blood flow, check how well drugs work, and see how active the brain is. A PET scan is a type of imaging test that uses radioactive tracers to look at the function and structure of organs and tissues in your body. A small amount of radioactive material is injected into your bloodstream and then scanned by a special camera. The camera creates pictures that show where the material has collected. This can help doctors see how well an organ is working or find tumors or other problems.

PET scan is short for positron emission tomography. It's a type of medical imaging that uses a radioactive tracer to look at organ function or tissue metabolism. The tracer is a small amount of radioactive material that's injected into the patient's bloodstream. It collects in organs and tissues, and a scanner detects the radiation emitted as it decays. This information is used to create cross-sectional images of the body that show how the organs and tissues are working. PET scans are most often used to detect cancer because tumors consume more energy than normal tissue and therefore have a higher metabolic rate. But they can also be used to evaluate other problems, such as heart disease, brain function, and joint damage.

PET scanning is a type of nuclear medicine imaging. A small amount of radioactive glucose (FDG) is injected into a vein and images are taken as the glucose moves through the body. Cancer cells use more energy than normal cells and therefore absorb more of the radioactive glucose. This allows tumors to be visualized on the scan. PET stands for Positron Emission Tomography. A PET scan is a medical imaging test that uses a radioactive tracer to look at organs and tissues inside the body. The tracer is injected into a vein, and images are taken as it moves through the body.

20% Health Time | A Smarter Way to Build Workplace Wellbeing

Modern workplaces are increasingly recognising that employee health is not separate from performance—it is foundational to it. Long work hours, constant digital connectivity and rising stress levels have led to burnout, lifestyle diseases and declining engagement across industries. In this context, the concept of 20% Health Time has emerged as a forward-thinking approach to workplace wellness.

20% Health Time allows employees to dedicate a portion of their paid working hours specifically to activities that support physical, mental and preventive health. Rather than treating wellness as an after-hours responsibility, this model integrates health directly into the work culture.

 

What Is 20% Health Time?

20% Health Time is a structured workplace initiative where employees are encouraged or allowed to spend approximately one-fifth of their working time on health-related activities.

These activities may include:

  • physical exercise or movement breaks
     

  • mental wellness practices
     

  • health education sessions
     

  • preventive health screenings
     

  • stress management and recovery
     

The core idea is simple: healthier employees perform better and sustain productivity longer.

 

Why Traditional Wellness Programs Fall Short

Many organisations offer wellness benefits such as gym memberships or annual checkups. While valuable, these programs often fail because:

  • employees lack time to use them
     

  • wellness is seen as optional
     

  • participation remains low
     

  • benefits are disconnected from daily work
     

20% Health Time addresses these gaps by embedding wellness into regular work hours.

 

Why Health Time Matters in Today’s Workplace

Rising Lifestyle Disease Burden

Public health data shows increasing rates of:

  • diabetes
     

  • hypertension
     

  • obesity
     

  • mental health disorders
     

These conditions affect working-age adults and directly impact productivity and healthcare costs.

 

Burnout and Mental Fatigue

Constant pressure and lack of recovery time lead to:

  • chronic stress
     

  • disengagement
     

  • absenteeism
     

  • high attrition
     

Health Time creates space for recovery and resilience.

 

Sedentary Work Culture

Desk-bound work contributes to:

  • musculoskeletal problems
     

  • cardiovascular risk
     

  • low energy levels
     

Dedicated health time encourages movement and prevention.

 

How 20% Health Time Benefits Employees

Improved Physical Health

Regular movement and preventive care reduce long-term health risks.

 

Better Mental Wellbeing

Time for mindfulness, rest and stress management improves emotional balance.

 

Higher Energy and Focus

Healthy routines improve concentration and reduce fatigue.

 

Empowerment and Autonomy

Employees feel trusted to manage their wellbeing, increasing engagement.

 

How Employers Benefit from 20% Health Time

Increased Productivity

Healthy employees work more efficiently and make fewer errors.

Reduced Absenteeism

Preventive care lowers sick days and health-related disruptions.

 

Lower Healthcare Costs

Early detection and healthier habits reduce long-term medical expenses.

 

Stronger Employer Brand

Wellbeing-focused policies attract and retain top talent.

 

Sustainable Performance

Health Time supports long-term performance rather than short-term output.

 

Activities That Fit into 20% Health Time

Organisations can tailor activities based on workforce needs:

  • guided fitness or yoga sessions
     

  • walking or movement breaks
     

  • mental health workshops
     

  • preventive health checkups
     

  • nutrition education
     

  • stress and sleep management programs
     

Flexibility ensures inclusivity across roles and work models.

 

Evidence Supporting Health Time Initiatives

Workplace health research consistently shows that:

  • preventive health improves productivity
     

  • employee wellbeing programs reduce burnout
     

  • time invested in health yields measurable returns
     

According to WHO and workplace wellness studies, integrated health initiatives deliver better outcomes than standalone benefits.

 

Addressing Common Concerns

“Will this reduce working hours?”

No. Health Time improves efficiency, offsetting time spent through better performance.

 

“Is it suitable for high-pressure roles?”

Yes. High-stress roles benefit the most from structured recovery time.

 

“How do we measure impact?”

Metrics may include:

  • reduced absenteeism
     

  • improved engagement scores
     

  • lower healthcare claims
     

  • better retention
     

 

Implementing 20% Health Time Effectively

Successful implementation requires:

  • leadership support
     

  • clear guidelines
     

  • flexible scheduling
     

  • inclusive activity options
     

  • regular feedback
     

Health Time works best when seen as a cultural shift, not a perk.

 

Long-Term Impact on Organisational Health

Over time, organisations adopting Health Time observe:

  • healthier workforce
     

  • improved morale
     

  • reduced burnout
     

  • stronger team cohesion
     

  • sustainable growth
     

These benefits compound year after year.

 

Conclusion

20% Health Time represents a progressive shift in how organisations view employee wellbeing. By dedicating work time to health, companies acknowledge that productivity and wellbeing are deeply connected. Rather than reacting to burnout and illness, Health Time promotes prevention, balance and resilience. In a future where talent, performance and sustainability matter more than ever, integrating health into the workday is not a luxury—it is a strategic necessity.
