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.

Auto antibodies that target the body’s DNA-repair process may provide researchers with some clues about why some children develop cancer. It has opened new avenues for early detection and appropriate treatment, according to a study published in Frontiers in Immunology recently.

A team of researchers from Norway, through the study, identified that children with cancer were more likely to have antibodies that target proteins tasked with repairing damaged DNA.

In a separate group of children whose blood samples had been collected years before they developed cancer, those who were later diagnosed were about eight times more likely to carry these antibodies than their peers who remained free of cancer.

The findings suggest that these antibodies could be an important marker of early indicator of cancer risk. However, the researchers state that further studies are needed to prove whether the antibodies contribute to cancer development and whether they can reliably predict the disease years before.

Antibodies are proteins that are generated by the immune system. They help recognise and neutralise foreign bodies, like viruses and bacteria.

Sometimes, however, the immune system produces autoantibodies, which mistakenly target the body’s own proteins.

The study found that some children with cancer had elevated levels of autoantibodies against six proteins involved in DNA repair. They are RAD52, NUMA1, ALKBH7, APBB1, UNG and MGMT.

DNA repair is essential because cells constantly go through damage that can lead to errors into their genetic material. When these errors are not corrected, mutations may accumulate and gradually contribute to cancer.

The researchers proposed an unproven theory that the antibodies might enter cells and bind to protein responsible for DNA repair, interfering with their normal function.

Their laboratory experiments provided evidence that these antibodies can enter living cells and localise to a cellular compartment called the TIGER domain.

“We showed that many children with various types of cancer have antibodies against some of their own DNA repair proteins. We also demonstrated that such ‘auto-antibodies’ can enter live cells and bind to – and probably inhibit – the activity of these essential proteins,” said corresponding author Dr Ola Myklebost, emeritus professor of molecular oncology at the University of Bergen.

If the antibodies do impair DNA repair, they could contribute to the accumulation of genetic damage. However, this mechanism has not yet been conclusively observed in humans.

Could A Blood Test Predict Cancer Years In Advance?

To investigate whether the antibodies appeared before cancer diagnosis, the researchers examined blood samples from 59 children who participated in two British long-term studies: the Avon Longitudinal Study of Parents and Children and Born in Bradford.

Half of the children were subsequently diagnosed with cancer before the age of 30, while the other half had not developed the disease. On average, the blood samples from those who later developed cancer had been collected approximately six years before diagnosis.

“Although this cohort is small, it was the best we could find internationally,” Myklebost said.

He added that children who later developed cancer were about eight times more likely to have antibodies against at least one key DNA-repair protein.

The researchers analysed samples from a broader group of 375 healthy individuals and patients, alongside cancer samples from adults and children with sarcoma or acute lymphoblastic leukaemia.

Childhood cancers are often biologically different from adult cancers. Unlike many adult malignancies, which can accumulate mutations over decades, paediatric cancers may arise in developing cells with fewer accumulated genetic changes. The researchers believe the immune system could play an important role in some cases.

However, the findings do not establish that the antibodies cause cancer. The study also cannot determine how accurately an antibody test would predict future disease in the general population.

The researchers are now investigating whether these antibodies affect DNA repair in laboratory-grown cells and plan to study their potential cancer-causing effects in animal models.

“At present we are investigating the effect of patient antibodies on the repair of induced mutations in cultured cells. Ultimately, we hope to clone white blood cells that secrete such auto-antibodies, and test for any cancer causing effects in mice to definitively prove our hypothesis,” Myklebost said.

Atorvastatin, a widely prescribed statin, helps lower cholesterol and reduce the risk of heart attacks and strokes. However, stopping the medication without medical advice can allow cholesterol levels to rise

again. Higher cholesterol levels have been linked to increased risk of heart attacks and other cardiovascular conditions.

Pharmacist Raj Patel recently warned about this in a TikTok video, comparing stopping the drug to giving up regular exercise.

“What happens if you stop taking atorvastatin? You know when you stop exercising for a month and everything slips back?” Patel asked.

“That's what happens when you stop atorvastatin. Your cholesterol creeps back up and so does your heart attack risk,” he warned.

According to the UK's National Health Service (NHS), cholesterol levels may rise again after stopping atorvastatin. Patients should continue taking it unless their doctor advises otherwise.

Atorvastatin belongs to a class of medicines called statins. It reduces cholesterol production in the liver and helps prevent heart attacks and strokes. Doctors may prescribe it to people with high cholesterol or an increased risk of cardiovascular disease, including those with diabetes or a family history of heart disease.

High cholesterol can cause fatty deposits to build up inside blood vessels, restricting blood flow. Statins help lower cardiovascular risk, particularly in people with existing heart disease or other risk factors.

Which Medicines Interact With Atorvastatin?

The NHS previously warned that certain medicines can interact with atorvastatin and increase the risk of serious side effects, including muscle damage. Patients should tell their doctor or pharmacist about all medicines and supplements they take.

On its website, the NHS lists certain “cautions with other medicines.” This means you should check that atorvastatin is safe to take alongside any other drugs or supplements.

The NHS explained: “Some medicines can affect the way atorvastatin works and can increase the chances of you having serious side effects, such as muscle damage.” You should tell your doctor or pharmacist if you are taking any of the following:

• Antibiotics: Erythromycin, clarithromycin, rifampicin and fusidic acid
• Antifungals: Ketoconazole, voriconazole and fluconazole
• Other treatments: Certain HIV and hepatitis C medicines
• Other medicines: Warfarin, ciclosporin, colchicine and some contraceptive pills
• Heart medicines: Verapamil, diltiazem, amlodipine and amiodarone

Depending on the interaction, a doctor may adjust the dose, prescribe another statin or temporarily pause treatment. Check with a healthcare professional before taking supplements.

What Are The Common Side Effects?

According to the NHS, common side effects affecting more than one in 100 people include:

• Nausea or indigestion
• Headaches and nosebleeds
• Sore throat and cold-like symptoms
• Constipation, bloating or diarrhea

“Drinking large amounts of alcohol regularly increases the risk of side effects and liver problems while taking atorvastatin,” the NHS added. “If side effects make you want to stop taking the medicine, speak to your doctor first. They may be due to another cause, and your doctor can suggest lowering the dose or switching medicines.”

Pope Leo XIV’s lung cancer diagnosis has raised questions about whether a lung nodule always signals cancer.

The 71-year-old pontiff announced in a post on X this week that doctors had detected a small, localized lung nodule during medical examinations. The nodule was detected at a very early stage, and doctors recommended surgery to remove it.

According to Vatican News, surgeons at Gemelli Hospital removed the lower lobe of his right lung using a video-assisted technique. Examination of the tissue confirmed lung adenocarcinoma, the most common subtype of non-small cell lung cancer (NSCLC), accounting for roughly 40% of lung cancer cases.

“An intraoperative histological examination confirmed the diagnosis of lung adenocarcinoma, as suspected from the preoperative examinations,” the statement said.

But does finding a lung nodule always mean cancer? HealthandMe spoke to experts to understand which nodules need further investigation and what warning signs to watch for.

A lung nodule is a small, localized spot in the lung, usually detected during a chest X-ray or CT scan. Most are benign, but some may indicate early lung cancer.

Dr Dipanjan Panda, Senior Consultant, Medical Oncology, Indraprastha Apollo Hospital, Delhi, told HealthandMe, that lung nodules can develop for several reasons, including infections, inflammation and, in some cases, cancer.

Does a Lung Nodule Mean Cancer?

Doctors assess a nodule’s size, shape, density and growth, along with the patient's age, smoking history and other risk factors. Depending on these findings, they may recommend follow-up CT scans, PET-CT imaging or a biopsy.

“A lung nodule is not synonymous with cancer. Most nodules are benign, often related to previous infections or scarring. Their size, appearance, growth, and the patient’s risk factors determine whether surveillance with repeat CT, PET-CT, or biopsy is needed. The key is appropriate risk assessment, not panic or unnecessary testing,” Dr Karn Mehra, Senior Consultant and Unit Head, Advanced Lung Failure and Transplant Pulmonologist, Fortis Hospital, Manesar, told HealthandMe.

Dr Raajit Chanana, Director and Senior Consultant, Medical Oncology, Dharamshila Narayana Superspeciality Hospital, Delhi, highlighted several factors that may raise concern about malignancy:

• Size: Larger nodules generally carry a higher risk of malignancy.
• Growth: An enlarging nodule warrants further evaluation, while stability over time can be reassuring.
• Appearance: Irregular or spiculated edges are more concerning than smooth, well-defined borders.
• Smoking history: Current and former smokers face a higher risk of lung cancer.
• Personal and environmental factors: A previous cancer diagnosis, family history of lung cancer, and exposure to asbestos or radon may increase concern.
• Persistent cough, coughing up blood, unexplained weight loss, chest pain or breathlessness should prompt medical evaluation.

Can Lung Cancer Affect Non-Smokers?

Although tobacco remains a major risk factor, lung cancer can also develop in people who have never smoked.

Dr Mehra noted that lung cancer in never-smokers is increasingly being recognized, including among younger adults. Air pollution, occupational exposures and genetic susceptibility may also contribute to the risk.

However, living in a polluted city alone does not justify annual CT scans. Screening should follow established risk criteria, particularly those based on age and smoking history. Low-dose CT can detect early lung cancer in eligible high-risk individuals, while indiscriminate scanning can lead to radiation exposure, false-positive results and unnecessary procedures.

Once lung cancer is confirmed, doctors determine its subtype, stage and molecular profile to guide treatment. Depending on these findings, treatment may include surgery, radiotherapy, targeted therapy, immunotherapy or chemotherapy.

For nodules not confirmed as cancer, management depends on their size, appearance, growth and the patient's risk factors. Small, low-risk nodules may require periodic CT scans, while suspicious ones may need further imaging or a biopsy. Not every nodule requires an invasive procedure.

Why Is Follow-Up Important?

“A lung nodule is not a cancer diagnosis, but it should never be ignored. Completing recommended follow-up scans is crucial. Quitting smoking remains one of the most effective ways to reduce lung cancer risk. Long-term smokers aged 50 and above should discuss whether they qualify for annual low-dose CT screening,” Dr Chanana said.
