Heatwave and Mental Health (Credit-Freepik)
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.

Influenza strain H1N1, formerly known as swine flu, is rising significantly in India, with deaths also being reported in some states.
H1N1 is a subtype of Influenza A and can cause sudden fever, cough, sore throat, headache, body aches and fatigue. These symptoms can overlap with those of other seasonal influenza strains, COVID-19 and respiratory syncytial virus (RSV), making it difficult to identify the infection based on symptoms alone.
Delhi: According to official data, Delhi has reported 1,349 confirmed H1N1 infections. No official deaths have been reported.
Kerala: A total of 2,468 influenza cases were recorded in the state in July, with 24 deaths reported during the month. The total number of cases recorded in the state this year stands at 5,519, with 60 deaths reported.
Maharashtra: The state has reported 25 laboratory-confirmed H1N1 cases, including a major spike of 15 cases in July. One confirmed death was officially verified by the Nagpur Municipal Corporation (NMC) Death Audit Committee.
Gujarat: H1N1 activity is also being reported, with Ahmedabad currently seeing a rise in cases.
Although H1N1 influenza primarily affects the respiratory tract, the infection can also put additional strain on the heart in some people, particularly those with a chronic history of cardiovascular disease, experts told HealthandMe.
Fever, dehydration, increased levels of carbon dioxide in the body, decreased oxygen levels and the body’s inflammatory response can increase the workload on the heart during an H1N1 infection.
This added strain may be more concerning for people who already have cardiovascular disease, said Dr. Praveen Raman Mishra, Associate Consultant, Institute of Cardiac Sciences at ShardaCare – Healthcity.
Some H1N1 influenza patients may experience cardiovascular complications, including:
Dr. Saurabh Gupta, Associate Director, Internal Medicine, Yashoda Medicity, added that H1N1 infection may cause fluctuations in heart rhythm or inflammation associated with the heart.
“In some circumstances when suffering from the H1N1 virus, although the initial symptoms of the virus may be those shared with the normal flu, such as temperature, aches and cough, those with pre-existing heart conditions should be more vigilant whilst they’re recuperating,” he told HealthandMe.
“As the infection puts more work on the body, you can find that previous heart problems are more noticeable,” he added.
The experts noted that people recovering from H1N1 should seek medical attention if they develop symptoms such as:
People with a chronic history of cardiovascular disease may face greater strain on the heart during H1N1 infection.
Monitoring symptoms during recovery and seeking medical attention when concerning symptoms develop can help identify cardiovascular problems early.

For many women, menopause can bring a string of uncomfortable symptoms like hot flashes, sleep problems, changing body composition and weight gain.
Now, researchers are looking at whether combining GLP-1-based weight-loss medicines with menopausal hormone therapy (MHT) could offer greater benefits, particularly for women struggling with obesity after menopause.
A recent Mayo Clinic study, published in The Lancet Obstetrics, Gynaecology & Women's Health, found that postmenopausal women taking tirzepatide along with hormone therapy lost about 35% more weight than those taking tirzepatide alone.
Researchers studied 120 postmenopausal women with overweight or obesity who had been taking tirzepatide for at least 12 months. Forty women were also using MHT, while 80 were not.
Women taking both treatments lost around 17-19% of their body weight, compared with about 14% among those taking tirzepatide alone. About 45% of women on the combination achieved at least 20% weight loss, compared with 18% in the tirzepatide-only group.
“This study provides important insights for developing more effective and personalized strategies for managing cardiometabolic risk in postmenopausal women,” said Dr Regina Castaneda, first author and Mayo Clinic researcher.
However, this was just an observation in the study, not a randomized clinical trial. Therefore, it cannot prove that hormone therapy itself caused the additional weight loss.
“It is possible that women using hormone therapy were already engaged in healthier behaviors, or that menopause symptom relief improved sleep and quality of life,” said Dr Maria Daniela Hurtado Andrade, senior author of the study.

During menopause, declining oestrogen levels can change fat distribution, appetite, metabolism and muscle mass. GLP-1 medicines, meanwhile, reduce appetite and slow stomach emptying, helping with weight management.
Researchers believe there could also be a biological interaction between oestrogen and GLP-1 signalling. “Preclinical data suggest a potential synergy, with estrogen appearing to enhance the appetite-suppressing effects of GLP-1,” Castaneda said.
Earlier research has also suggested greater weight loss among postmenopausal women using semaglutide alongside hormone therapy.
A 2026 review similarly concluded that GLP-1 medicines may help reduce weight and abdominal fat in menopausal women, but larger studies are needed.

GLP-1 medicines may cause nausea, vomiting, diarrhoea, constipation, abdominal pain and reduced appetite. These effects often surface when the dose is increased.
Hormone therapy has its own side-effects and it is also not suitable for everyone. Depending on the patient's medical history, MHT can increase the risk of complications like blood clots and stroke.
Hormone therapy should not be started simply to fuel weight loss from a GLP-1 drug. It is primarily used to treat certain menopause symptoms and should be prescribed after considering a woman's age, symptoms, medical history and individual risks.
As Hurtado Andrade noted, researchers now want to determine whether the combination offers benefits beyond weight loss, including improvements in cardiometabolic health.

It can be confusing and sometimes alarming to receive different thyroid test results from two different laboratories, especially when both tests are done on the same day. A slight difference in values does not necessarily mean that your thyroid function has suddenly changed. In many cases, the variation is due to differences in how the tests are performed rather than a change in your health.
One of the biggest reasons for varying results is the laboratory itself. Accredited laboratories, such as NABL-certified labs, follow stringent quality-control measures, use standardised testing protocols and have trained personnel to handle samples correctly. Laboratories with less rigorous quality standards may produce results that are less consistent.
The equipment and testing methods used can also differ from one laboratory to another. Different analysers, calibration techniques and testing kits can produce slightly different values for thyroid hormones such as TSH, T3, T4, Free T3 and Free T4.
Even the reference ranges printed on reports may not be identical because each laboratory establishes its own normal range based on the equipment used and the population it serves.

The timing of the test is another important factor. Thyroid-stimulating hormone (TSH) naturally fluctuates throughout the day. It is generally higher during the early hours of the morning and gradually falls as the day progresses.
As a result, a blood sample collected in the afternoon may show a lower TSH level than one collected early in the morning.
Lifestyle and biological factors can also influence thyroid hormone levels. Stress, poor sleep, recent illness, medications and even eating before the test may affect the results.
For people taking thyroid medication, blood samples should ideally be collected in the morning on an empty stomach and before taking the daily dose. Testing after medication may temporarily alter hormone levels and make interpretation more difficult.

Certain supplements and medications can interfere with thyroid tests as well. Biotin, commonly found in hair and nail supplements, can falsely lower TSH levels while increasing Free T3 and Free T4 values.
Medications such as amiodarone, glucocorticoids, dopamine and heparin may also affect thyroid hormone measurements. During pregnancy, hormonal changes, particularly increased levels of human chorionic gonadotropin (hCG), can naturally alter TSH values.
Laboratory handling also plays a role. Delays in processing, improper storage temperatures, differences in centrifugation timing or sample-handling errors can influence the final result.
In some individuals, thyroid autoantibodies may interfere with laboratory assays, potentially leading to inaccurate Free T3 and Free T4 measurements.

Because of these variables, experts recommend getting thyroid tests done at the same accredited laboratory whenever possible. This allows doctors to compare results more reliably over time.
If a thyroid value is only mildly abnormal or falls within a borderline range, it may often be advisable to repeat the test before making a diagnosis or starting lifelong medication.
Ultimately, thyroid test reports should never be interpreted in isolation. Doctors consider the patient's symptoms, medical history, physical examination and repeat test results before deciding on treatment.
Consistency in where and how the test is performed can help avoid unnecessary anxiety and support more accurate clinical decisions.
