The heat waves are rising all over the world and causing a lot of damage. While there are issues of dehydration and heat strokes, studies are suggesting that it might also be responsible for declining mental health, the heat among other things is not only affecting the physicality of human beings but is also having adverse mental health.

Emotional distress: The heat can trigger mood swings, making you feel irritable, anxious, depressed, or even aggressive. You may not be able to predict your reaction, you may be good one moment and then any minor inconvenience will make you angry or sad. Heat often triggers that helplessness in people.

Scattered Focus: Concentrating on tasks becomes a struggle when it's hot. Simple things feel overwhelming, and staying focused is a challenge. While you may be in the zone working on completing something, the heat and sweating will disrupt your flow and then you will not be able to focus on anything other than the heat.

Sleepless Nights: High temperatures, especially at night, disrupt your sleep. This lack of rest can leave you feeling tired, and grumpy, and worsen existing mental health issues. All humans require a comfortable temperature to sleep in, if your body is too wound up or heated up, it will not be able to relax and sleep.

Feeling the Pressure: The heat can pile on stress and make you feel overwhelmed. Concerns about the heat itself or its impact on other aspects of your life can contribute to this feeling. You will feel overwhelmed and unable to work on anything else. The heat makes you feel a certain helplessness, as you cannot stop the sun or turn down the heat.

Body Blues: The heat can cause physical symptoms that affect your mental well-being. Headaches, fatigue, dizziness, and nausea can all contribute to anxiety and low mood. When your body is already fatigued, the urge to do anything else disappears. Your body is drained of energy to function at all and will seek rest and sleep.

Behavioural Shifts: The heat can influence your behaviour. You might act impulsively or have difficulty managing anger. It's like the heat turns up your emotional thermostat. When your body and brain are overheating, it is difficult to think straight and you will grasp at straws to release this energy and pressure off of you.

Some other side effects of the heat are.

• Mental Health Flare-Ups: If you already have a mental health condition, hot weather can worsen your symptoms. Existing depression, anxiety, bipolar disorder, or schizophrenia might feel more intense.
• Heat and Suicide Risk: Studies show a disturbing link between hot weather and increased suicide rates, particularly among men and older adults. Hot weather can be a tipping point for those already struggling.
• Heatwave Hospitalizations: When temperatures soar, people with existing mental health issues may require increased hospitalization. This highlights the need for healthcare systems to be prepared for heat waves.
• Climate Change and Mental Health: Climate change is leading to more frequent heatwaves. Research suggests this could lead to a rise in mental health problems and suicides. Taking action against climate change is crucial for protecting mental well-being.

Over 57 million people worldwide live with dementia, causing 36.3 million disability-adjusted life years (DALYs) and ranking as the seventh leading cause of death. But when it comes to dementia, memory loss is often the first symptom that comes to mind.

While forgetting birthdays or losing keys are commonly considered early warning signs of dementia, this may not always be the case.

Experts say a person can remember every birthday and anniversary and still have dementia.

What Are The Early Signs Of Dementia?

“Dementia may not begin with memory loss. It can begin with smell, language, personality or navigation,” Dr Priyam, an internal medicine resident from Assam, said in a post on the social media platform X.

1. Loss Of Smell: When Coffee Stops Smelling Like Coffee

Dr Priyam noted that loss of smell can be an early sign, but it is often overlooked because it may be attributed to a viral illness, sinus disease, smoking, medicines or a head injury.

“Persistent, unexplained smell loss may also be an early clue to Parkinson’s disease or dementia with Lewy bodies,” he added.

2. Everyday Words Start Disappearing

It is not simply an occasional tip-of-the-tongue moment. “In primary progressive aphasia, word-finding, grammar or comprehension may worsen while recent memory stays intact,” Dr Priyam noted.

3. The Family Says, “They Are Not The Same”

Changes in personality or behaviour may sometimes appear before memory problems.

“In behavioral-variant frontotemporal dementia, apathy, impulsiveness, loss of empathy or poor judgment may come before memory loss,” Dr Priyam said.

4. A Familiar Route Suddenly Feels New

Families may notice navigation problems even when a person has no obvious memory complaints. “Families ask me, ‘He has driven there for 20 years. How did he get lost?’ When it repeats, I look beyond forgetfulness,” Dr Priyam said.

He noted that visuospatial dysfunction can appear early in dementia with Lewy bodies or posterior cortical atrophy.

One Odd Symptom Does Not Necessarily Mean Dementia

Dr Parveen Yograj, a general surgeon from Jammu, added that one unusual symptom alone means little.

"A new, persistent and progressive pattern that disrupts daily life and is noticed by loved ones is what demands attention," he said on X.

How Can Dementia Risk Be Reduced?

Dr Yograj said several lifestyle measures may help protect brain health and reduce the risk of cognitive decline.

• Exercise Regularly: Regular aerobic exercise along with strength training can boost brain blood flow and build cognitive reserve.
• Follow A Brain-Healthy Diet: A Mediterranean or MIND diet, rich in vegetables, berries, nuts, olive oil and fish, can support vascular health.
• Prioritize Good Sleep: Solid sleep helps clear toxic brain waste and supports overall brain health.
• Keep Blood Pressure, Sugar And Cholesterol In Check: Managing blood pressure, blood sugar, cholesterol and weight can help reduce the risk of vascular dementia.
• Stay Socially And Mentally Active: Stay socially connected and mentally engaged by talking with others, reading, learning new skills and playing games.
• Quit Smoking And Limit Alcohol: Avoiding smoking, limiting alcohol and treating hearing loss early can also support long-term brain health.

Organ transplantation can offer patients with end-stage organ failure a new opportunity for a longer, healthier, and more independent life. However, transplantation is not the end of treatment—it marks the beginning of a lifelong commitment to maintaining the health and function of the transplanted organ.

Successful long-term outcomes depend on close collaboration between the organ recipient, living donor, transplant team, and family. Regular medical follow-up, adherence to prescribed medications, a healthy lifestyle, and early recognition of warning signs are essential for both recipients and living donors.

Care After Organ Transplantation

1. Strict Adherence to Immunosuppressive Medications

For most solid-organ transplant recipients, lifelong immunosuppressive therapy is required to prevent the immune system from attacking the transplanted organ.

Medications such as tacrolimus, cyclosporine, mycophenolate, corticosteroids, and other immunosuppressive agents may be prescribed depending on the type of transplant and the individual patient's condition.

Recipients should:

• Take medications exactly as prescribed and at the recommended times.

• Never stop or reduce immunosuppressive medication without consulting the transplant team.

• Avoid missing doses.

• Inform their transplant physician before starting any new medication.

Even seemingly minor changes in medication can affect drug levels and may increase the risk of acute or chronic rejection.

2. Regular Follow-Up and Laboratory Monitoring

Regular follow-up with the transplant team is an essential component of lifelong transplant care.

Depending on the transplanted organ and individual circumstances, monitoring may include:

• Kidney and liver function tests

• Complete blood counts

• Immunosuppressive drug levels

• Blood pressure and blood glucose monitoring

• Urine examination in kidney transplant recipients

• Imaging or other investigations when clinically indicated

These evaluations help detect rejection, infection, medication toxicity, or deterioration in graft function at an early stage, sometimes before symptoms become apparent.

3. Recognizing Warning Signs

Transplant recipients should promptly contact their transplant team if they develop symptoms such as:

• Unexplained or persistent fever

• Chills or significant weakness

• Reduced urine output, particularly after kidney transplantation

• Swelling or sudden weight gain

• Breathlessness or persistent cough

• Persistent pain over the transplant site

• Persistent vomiting or diarrhoea

• Unexplained changes in blood pressure or blood sugar

Because immunosuppressive medications reduce the body's immune response, infections may develop more easily and may sometimes present with subtle symptoms. Early medical assessment is therefore important.

4. Infection Prevention

Transplant recipients are more susceptible to infections, particularly during periods of intensive immunosuppression.

Important preventive measures include:

• Practising regular hand hygiene

• Avoiding close contact with individuals who have contagious infections

• Following appropriate food-safety precautions

• Drinking safe and hygienic water

• Maintaining good personal hygiene

• Keeping vaccinations up to date as advised by the transplant team

• Seeking medical advice promptly if symptoms of infection develop

Recipients should also follow the specific infection-prevention recommendations provided by their transplant centre.

5. Healthy Nutrition and Lifestyle

A balanced and nutritious diet is an important component of long-term transplant health.

Recipients should aim to:

• Maintain a healthy body weight

• Eat a balanced diet rich in vegetables, fruits, whole grains, and appropriate sources of protein

• Maintain adequate hydration unless fluid restriction has been advised

• Limit excessive salt, sugar, and processed foods

• Exercise regularly according to their medical condition and physician's advice

• Avoid smoking and tobacco products

• Avoid excessive alcohol consumption

Certain foods, supplements, and herbal preparations may interact with immunosuppressive medications. No dietary supplement, herbal preparation, or over-the-counter medication should be started without discussing it with the transplant team.

Post-Donation Care for Living Organ Donors

Living organ donation is a remarkable act of generosity. However, protecting the donor's long-term health remains the highest priority.

After donation, the donor should remain under appropriate medical supervision and follow the recommendations of the transplant and surgical team.

1. Recovery After Donation

The recovery period varies depending on the type of donation and the individual's overall health.

Donors should:

• Follow wound-care instructions carefully.

• Take prescribed medications as directed.

• Get adequate rest during the initial recovery period.

• Gradually resume physical activity as advised.

• Avoid strenuous exercise and heavy lifting until medically cleared.

• Return to work and normal activities progressively.

The recovery process should be individualized rather than based solely on a fixed timeline.

2. Long-Term Health After Kidney Donation

Most carefully selected kidney donors can lead healthy, active lives with a single functioning kidney.

Long-term health recommendations include:

• Maintaining a healthy body weight

• Exercising regularly

• Eating a balanced diet

• Staying adequately hydrated

• Avoiding tobacco

• Avoiding unnecessary use of potentially kidney-toxic medications, particularly certain painkillers such as NSAIDs

• Monitoring blood pressure

• Periodically checking kidney function and urine as recommended

Living donation should never mean that donors stop looking after their own health. The donor's well-being remains a lifelong priority.

Any new or persistent symptoms should be reported to a healthcare professional.

3. Emotional and Psychological Well-Being

Transplantation and organ donation can have a significant emotional impact on both recipients and donors.

Recipients may experience anxiety related to rejection, medication, financial concerns, or the uncertainty associated with transplantation. Living donors may also experience emotional changes during the recovery period.

Maintaining open communication with family members and the transplant team can be extremely helpful. If persistent anxiety, depression, sleep disturbances, or emotional distress develops, professional psychological or psychiatric support should be sought.

4. The Importance of Lifelong Follow-Up

The success of organ transplantation depends not only on the surgical procedure but also on long-term post-transplant care.

For recipients, medication adherence, regular monitoring, infection prevention, and a healthy lifestyle are essential to preserving graft function.

For living donors, appropriate postoperative recovery, long-term health monitoring, and healthy lifestyle practices help ensure that they continue to live healthy and fulfilling lives after donation.

The transplant may be a single surgical event—but maintaining the gift of life is a lifelong journey.

With appropriate medical supervision, adherence to treatment, healthy lifestyle choices, and timely attention to warning signs, organ recipients can protect the health of their transplanted organ, while living donors can continue to enjoy a healthy and active life after their selfless contribution.

By Dr. Pragnesh Desai, Senior Director & HOD – Urology, Renal Transplant, Robotics & Uro-Oncology, Yatharth Super Speciality Hospital, Noida Extension

Organ donation is one of the most generous gifts a person can give. Age, diabetes, hypertension or other medical conditions do not automatically rule out organ donation, doctors said on World Organ Donation Day.

Observed on August 13 every year, World Organ Donation Day aims to raise awareness about the need for organ and tissue donation and honour donors and their families.

Organ Donation After Brain Death

Dr. Umesh Gupta, Director and HOD, Nephrology and Kidney Transplant, Aakash Healthcare Multi-Speciality Hospital, Dwarka, told HealthandMe that organ donation can be considered when brain function is permanently lost and cannot be restored.

Brain death occurs when all functions of the brain and brainstem have permanently stopped.

“Brain death is different from a coma or a prolonged unconscious state. In brain death, the person cannot regain consciousness or breathe independently. Mechanical support may continue to keep the heart beating and preserve the condition of organs for a limited period, which is why organ donation can be considered,” he said.

Depending on the donor’s medical condition, organs such as the heart, liver, kidneys, lungs and pancreas may be suitable for transplantation.

Who Can Donate Organs?

Age alone does not rule out organ donation. Eligibility is assessed individually by the transplant team.

Doctors evaluate:

• Health and functioning of individual organs
• Existing illnesses
• Infections
• Medical history
• Other factors that could affect transplant safety

Can People With Diabetes or Hypertension Donate?

People with well-controlled diabetes or hypertension may still be eligible to donate certain organs or tissues, said Dr. Shailesh Chandra Sahay, Senior Director - Urology, Kidney Transplant, Robotic Surgery, Max Super Speciality Hospital, Patparganj.

Modern transplantation practices allow doctors to assess each organ individually rather than excluding a donor solely because of age or a particular diagnosis.

Every potential donor deserves a medical evaluation. An organ that may appear unsuitable to a person could ultimately give another patient a second chance at life.

Blood Group Is Important — But Not the Only Factor

Blood group compatibility is an important consideration in organ transplantation.

“A blood group O donor typically donates to O recipients, while AB recipients can receive organs from all ABO blood groups in many transplant settings,” Dr. Saurabh said.

However, compatibility involves more than blood type. Doctors also assess:

• Tissue compatibility
• Antibodies
• Organ size
• Recipient’s overall health
