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.

Why Preventive Health Check-ups Are Important For Women

Updated Apr 6, 2026 | 04:01 PM IST

SummaryPeriodic health check-ups also provide an opportunity for counselling on nutrition, mental well-being, hormonal health, and lifestyle management, areas that are often overlooked but equally important.

World Health Day serves as a reminder that regular preventive health check-ups stand as mandatory health assessments that all women need to undergo for their long-term health.

Many serious conditions, such as breast cancer, cervical cancer, thyroid disorders, diabetes, and cardiovascular diseases, often remain silent in their early stages, making regular screening the most effective way to detect them early, when treatment is simpler, less invasive, and more successful.

How Preventive Healthcare Can Help Women

Preventive healthcare enables women to take a proactive role in managing their health rather than responding to illness at an advanced stage. Early detection not only improves clinical outcomes but also effectively decreases treatment difficulties, emotional distress and financial costs while providing superior long-term life quality.

This also helps in identifying risk factors early, allowing timely lifestyle modifications that can prevent disease onset altogether.

Despite this, women often deprioritize their own health due to the multiple roles they juggle, balancing careers, caregiving responsibilities, and family needs. There is also a continued hesitation around discussing reproductive and intimate health concerns, along with a lack of awareness, fear of diagnosis, and social stigma, all of which contribute to delays in seeking timely care.

In many cases, women assume that the absence of symptoms indicates good health, which is a common but risky misconception.

Importance Of Routine Screening

Routine screenings such as Pap smears for cervical health, regular breast examinations, mammography where indicated, thyroid function tests, and basic metabolic screenings like blood sugar and cholesterol levels are critical tools in preventive care.

Periodic health check-ups also provide an opportunity for counselling on nutrition, mental well-being, hormonal health, and lifestyle management, areas that are often overlooked but equally important.

World Health Day serves as a reminder to shift from a reactive to a preventive approach. Prioritizing regular health check-ups, normalizing conversations around women’s health, and encouraging a culture of self-care can significantly improve outcomes. Investing in preventive healthcare is one of the most powerful steps women can take towards leading healthier, longer, and more empowered lives.

Brain Aging: This Protein Is Linked to Memory Loss and Cognitive Decline

Updated Apr 6, 2026 | 01:11 PM IST

SummaryIncreasing FTL1 levels in young mice produced brain changes similar to those seen in older mice. The researchers found that this change occurs because of alterations in the way nerve cells produce FTL1 protein.

Aging is a significant factor in memory loss and cognitive decline. Now, a team of US researchers has pinpointed a single protein that drives these changes in the brains of the elderly.

In aging mice, higher levels of protein FTL1 weakened connections between brain cells, leading to memory decline.

But when FTL1 was reduced, the brain began to recover. It also rebuilt lost connections and restored memory performance, according to the study, published in Nature Aging.

"It is truly a reversal of impairments," said Saul Villeda, Associate Director at the University of California - San Francisco's Bakar Aging Research Institute and senior author of the paper. "It's much more than merely delaying or preventing symptoms."

While the research was carried out in aging mice, it holds immense potential for human brain function.

FTL1: A Key Driver Of Brain Aging

In the study, the researchers tracked shifts in genes and proteins in the hippocampus of mice. The FTL1 protein appeared consistently different between young and old animals.

Compared to young mice, the older mice showed higher levels of FTL1. They also had fewer connections between neurons in the hippocampus and performed worse on cognitive tests.

Increasing FTL1 levels in young mice produced brain changes similar to those seen in older mice. The researchers found that this change occurs because of alterations in the way nerve cells produce FTL1 protein.

In older mice, the nerve cells that produced high amounts of FTL1 developed simplified structures, forming short, single extensions instead of the complex, branching networks seen in healthy cells.

Further experiments showed that in older mice, higher levels of the protein slowed cellular metabolism in the hippocampus -- the part of the brain responsible for learning and memory.

However, when researchers treated these cells with a compound that boosts metabolism, the negative effects were prevented.

A Promise For Future Brain Aging Therapies

Villeda believes these findings could pave the way for treatments that target FTL1 and counter its effects in the brain.

"We're seeing more opportunities to alleviate the worst consequences of old age," he said. "It's a hopeful time to be working on the biology of aging."

Early-Stage Lung Cancer Surgery Safe, Effective Even After 80, Reveals Lancet Study

Updated Apr 6, 2026 | 01:18 PM IST

SummaryAccording to the American Cancer Society, lung cancer mainly occurs in older people. Most people diagnosed with lung cancer are 65 or older. It is also the leading cause of cancer death in the US, accounting for about 1 in 5 of all cancer deaths.

Cancer treatment has long been thought to be unsuccessful among people of advanced age, and older adults are often left out of clinical decisions.

While they may face more surgical complications, a new study proved that even people aged over 80 can still safely have surgery and be cured. It showed that the overall health of a patient matters more and that age must not be the only criterion to rule out surgery.

The study, published in The Lancet Regional Health – Americas, showed that surgery for lung cancer is safe in elderly patients aged 80 and above, especially when the cancer is in an early stage.

Researchers at the Icahn School of Medicine at Mount Sinai and the Mount Sinai Tisch Cancer Center in the US found that they can recover like young cancer patients as well as live longer like them.

“As our population ages, more patients over 80 are being diagnosed with early-stage lung cancer, yet they are often not considered for surgery,” said Raja M. Flores, Chair of the Department of Thoracic Surgery at Mount Sinai Health System.

“Our findings show that when patients are carefully selected based on their overall health, not just their age, they can tolerate surgery well and experience excellent long-term outcomes,” he added.

What Did The Study Find?

The study findings are based on a study of 884 patients with early-stage lung cancer, including 114 people who were age 80 or older.

The researchers examined surgical outcomes and quality of life in patients with early-stage non-small cell lung cancer, comparing those aged 80 and older with younger patients.

The results showed that older patients lived just as long as younger patients after surgery. While some older patients had more complications right after surgery, most patients in both groups felt better over time, and their quality of life improved within a year.

The study noted that early detection in older patients may be key. The researchers called for screening guidelines to include patients who are over 80 years old based on these findings.

What Is Lung Cancer?

Lung Cancer is one of the most common and serious types of cancer. It is also the leading cause of cancer-related deaths worldwide, with approximately 2.5 million new cases and 1.8 million deaths reported in 2022.

According to the American Cancer Society, lung cancer mainly occurs in older people. Most people diagnosed with lung cancer are 65 or older; a very small number of people diagnosed are younger than 45.

The average age of people when diagnosed is about 70.

It is also the leading cause of cancer death in the US, accounting for about 1 in 5 of all cancer deaths.

In many cases, there are no symptoms; however, one must look out for these:

  • a persistent cough
  • coughing up blood
  • persistent breathlessness
  • unexplained tiredness and weight loss
  • an ache or pain when breathing or coughing.

The two main types of lung cancers are:

Non-small-cell lung cancer (NSCLC): This is the most common form, making up about 80–85% of all cases. NSCLC includes three subtypes:

  • Squamous cell carcinoma
  • Adenocarcinoma
  • Large-cell carcinoma
Small-cell lung cancer (SCLC): Less common than NSCLC, this type tends to grow and spread more quickly.
