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.

Perimenopause Is Not Just About Periods: The Metabolic Changes Women Should Know About

Updated Oct 31, 2026 | 09:00 AM IST

SummaryPerimenopause involves metabolic changes that extend beyond irregular periods and hot flashes. Shifting hormone levels can influence insulin sensitivity, fat distribution, cholesterol and cardiovascular health. Explore how these changes affect women's long-term health and why monitoring metabolic markers during this transition matters.
Perimenopause Is Not Just About Periods: The Metabolic Changes Women Should Know About

When we think of perimenopause, irregular periods, hot flashes and mood changes usually come to mind. But the transition to menopause is not limited to the menstrual cycle. Behind the scenes, changing ovarian hormones—particularly fluctuating and eventually declining estrogen—can influence body composition, insulin sensitivity, cholesterol levels, bone health and cardiovascular risk.

For many women, these metabolic changes begin years before their final menstrual period.

Why does weight suddenly behave differently?

A common concern during perimenopause is: “I haven’t changed my diet, so why am I gaining weight around my abdomen?”

Ageing itself contributes to gradual loss of muscle mass and changes in energy expenditure. At the same time, the menopausal transition is associated with a shift in fat distribution, with a greater tendency to accumulate visceral or abdominal fat.

This matters because visceral fat is metabolically active. An increase in abdominal fat can be associated with insulin resistance, abnormal cholesterol levels and a higher risk of metabolic disease. So, the change in waist circumference may sometimes tell us more about metabolic health than the number on the weighing scale alone.

Blood sugars may raise up too

Estrogen interacts with several pathways involved in glucose and fat metabolism. During midlife, changes in body composition, reduced physical activity, sleep disturbance and hormonal changes can collectively make insulin sensitivity less favourable.

This does not mean every woman going through perimenopause will develop diabetes. However, women who already have risk factors—such as overweight or obesity, prediabetes, a history of gestational diabetes or a strong family history of type 2 diabetes—should be particularly mindful.

Cholesterol and heart health deserve attention

The menopausal transition can also be accompanied by unfavourable changes in the lipid profile, including changes in LDL cholesterol. Cardiovascular risk increases with age, and menopause is an important time to reassess risk factors such as blood pressure, glucose, cholesterol, smoking, physical activity and body composition.

Women often spend years focusing on reproductive health while overlooking these equally important metabolic markers.

Muscles and bones need attention as well

Midlife is also an important period for protecting muscle and bone. Declining estrogen after menopause accelerates bone loss, while ageing contributes to loss of muscle mass.

Resistance training therefore becomes especially valuable. Adequate protein intake, regular weight-bearing exercise, sufficient calcium and vitamin D, good sleep and avoiding smoking can support healthier ageing.

What should women do?

Perimenopause should not be viewed as a disease, nor should every symptom or kilogram gained in midlife automatically be blamed on hormones. Instead, it is an opportunity for a metabolic health check.

Women should discuss appropriate screening for blood pressure, blood glucose or HbA1c, lipid profile, weight and waist circumference monitoring , DEXA scan for bone health, depending on their individual risk factors.

Most importantly, don’t wait for menopause to start thinking about metabolic health. The perimenopausal years can be an important window to build muscle, improve fitness, optimise nutrition and identify metabolic risk early.

Perimenopause is more than a change in periods—it is a transition in whole-body health. Understanding these changes early can help women enter the next phase of life stronger, healthier and better prepared.

From haunted houses and sudden scares to sweet treats and costumes, Halloween fun can come with hidden health risks, particularly for people with existing heart and lung conditions.

Experts explain how sudden fright, excessive sugar and common activities on Halloween, observed on October 31, can affect heart and lung health.

How Sudden Scares Can Affect Your Heart

A sudden scare activates the body's sympathetic nervous system, raising heart rate and blood pressure while constricting blood vessels.

This response is usually harmless in healthy people, but may pose risks for those with arrhythmias, coronary artery disease or a history of stents or heart surgery.

A racing heartbeat should settle after the scare. Persistent palpitations, dizziness, shortness of breath, chest pain or tightness, nausea, sweating or fainting warrant medical attention, says Dr Mohamed Gabr, cardiologist and electrophysiologist at Baylor College of Medicine.

In addition, excessive consumption of sugar candies during Halloween can contribute to obesity, diabetes, high blood pressure and unhealthy cholesterol levels. Cholesterol and plaque buildup in the coronary arteries can begin at a young age.

Halloween Activities That Can Trigger Asthma

Halloween activities can expose people with asthma to several triggers. Ragweed pollen, mould on damp fallen leaves and cold, dry air can worsen symptoms during autumn, according to the American Lung Association.

Fog machines and dry ice effects in haunted houses can release water droplets and chemicals, including glycol-based solvents, that may irritate airways. Glitter machines, bonfire smoke, dust from stored costumes and decorations, and strong fragrances can also trigger symptoms.

Dr Rubabin Tooba, a pulmonologist with Northwestern Medicine, says these exposures may cause coughing, wheezing, breathlessness and chest tightness, particularly in people with asthma, severe allergies or COPD. Tight-fitting masks can also make breathing difficult.

Fear, excitement and laughter may trigger asthma symptoms in some people. Trick-or-treating can bring additional exposure to pet dander, scented candles, cigarette smoke and fireplace fumes.

Pumpkin Carving And Halloween Injuries

The US Consumer Product Safety Commission (CPSC) estimates that an annual average of 3,200 Halloween-related injuries were treated in US emergency departments over a recent three-year period.

Pumpkin carving accounted for 55% of these injuries, while 25% were related to falls while putting up decorations, tripping on costumes or walking while trick-or-treating. The remaining 20% involved lacerations, ingestions, allergic reactions and other costume- or decoration-related injuries.

Children younger than 18 years accounted for 46% of injuries, with approximately 10% occurring in children aged 6 years or younger.

The Plastic Hand Trauma Unit at Royal Devon and Exeter Hospital has also treated patients with deep cuts, severed tendons and nerve damage from pumpkin carving, BBC reported.

How Can You Stay Safe This Halloween

  • Protect your heart: Be mindful of sudden scares if you have an existing heart condition. Seek medical attention for persistent palpitations, chest pain, breathlessness or fainting.
  • Moderate candy: Limit sugary treats and consider fruit alternatives.
  • Avoid asthma triggers: Ask about fog effects at haunted attractions and leave if you experience breathing discomfort.
  • Check costumes and decorations: Clean stored items before use and discard anything with mould or a musty smell. Choose breathable, open-face masks.
  • Use makeup carefully: Choose fragrance-free or hypoallergenic products and apply them in well-ventilated spaces.
  • Carry asthma medication: Keep your prescribed quick-relief inhaler and spacer handy. Watch for coughing, wheezing or chest tightness, and take breaks when needed.
  • Reduce infection risks: Practise good hand hygiene, stay home when sick and keep vaccinations up to date.
  • Carve pumpkins safely: Avoid kitchen knives. Use pumpkin-carving kits with serrated tools and make small, controlled cuts.

Blood Pressure in Your Ankles? How the ABI Test Can Reveal Hidden Peripheral Artery Disease

Updated Oct 30, 2026 | 10:00 PM IST

SummaryThe ABI test compares blood pressure in the arms and ankles to detect poor circulation and peripheral artery disease (PAD). Early detection can help prevent complications and identify wider cardiovascular risks.
Blood Pressure in Your Ankles? How the ABI Test Can Reveal Hidden Peripheral Artery Disease

Blood pressure is routinely measured in the arms, but checking it in your ankles can also offer important clues about vascular health. An ankle-brachial index (ABI) test compares blood pressure readings in the arms and ankles to detect poor circulation and signs of peripheral artery disease (PAD).

Pain or cramping in the calves, thighs, hips or buttocks while walking, climbing stairs or exercising, which subsides with rest, could indicate PAD. The condition occurs when narrowed arteries restrict blood flow to the legs.

PAD can remain undetected for years, particularly in people without obvious symptoms. Early detection matters because the underlying atherosclerosis can also affect arteries supplying the heart and brain, increasing cardiovascular risks.

What Is an ABI Test and How Does It Detect Artery Disease?

The ABI test is a simple, non-invasive procedure that measures blood pressure in the arms and ankles using inflatable cuffs and a Doppler ultrasound device. The readings are compared to calculate the ankle-brachial index.

Dr. Samir Kubba, Director and Unit Head, Cardiology, Dharamshila Narayana Superspeciality Hospital, Delhi, explained to HealthandMe that the test assesses blood circulation in the lower limbs and can also indicate an increased risk of cardiovascular disease.

Dr. Anshul Kumar Jain, Director – Cardiology, CK Birla Hospital, Delhi, told HealthandMe that an abnormal ABI reading should not be viewed in isolation but as a potential warning sign requiring further cardiovascular assessment.

"What makes the ABI test particularly important is that PAD may remain undiagnosed for years, as some individuals experience no obvious symptoms," Dr. Samir said.

Others may experience leg pain while walking, cramps, numbness, cold feet or wounds that take longer to heal.

Dr. Anshul highlighted the wider implications of detecting PAD. "From a neurological perspective, identifying PAD is particularly important because underlying atherosclerosis can affect blood vessels supplying the brain as well as the heart. Reduced circulation may indicate an increased risk of cardiovascular events, including stroke," he said.

Who Should Consider an ABI Test?

The test may be useful for people at an increased risk of PAD, including:

  • Smokers and former smokers, particularly those over 50.
  • People with diabetes, high blood pressure or high cholesterol.
  • Individuals with a history of stroke or mini-stroke.
  • Adults over 65.
  • People with a strong family history of cardiovascular disease.

ABI is not a direct test for heart disease. It is a vascular assessment tool that helps identify PAD and may indicate wider cardiovascular risks. Abnormal results require further evaluation by a specialist.

How to Prepare for an ABI Test and What Happens During It?

No special preparation is required. You will be asked to lie on your back and rest for five to 10 minutes before the test.

A healthcare professional will place inflatable cuffs around your arms and ankles and measure blood pressure using a handheld Doppler ultrasound device. The procedure takes only a few minutes, and you can resume normal activities afterwards.

What Do ABI Test Results Mean?

The ABI is calculated by dividing the higher ankle systolic blood pressure reading by the higher arm reading. The resulting ratio indicates blood flow to the legs.

According to the Cleveland Clinic, ABI readings are interpreted as follows:

  • 1.0 to 1.3: Normal
  • 0.9 to 1.0: Borderline
  • 0.7 to 0.9: Mild PAD
  • 0.4 to 0.7: Moderate PAD
  • Below 0.4: Severe PAD

An ABI above 1.4 may indicate stiff or calcified arteries, often associated with ageing or diabetes. Such readings may require further testing.

People with diabetes or non-compressible arteries may also need a toe-brachial index (TBI) test, which measures blood pressure at the big toe.

How Is Peripheral Artery Disease Treated?

Treatment depends on the severity of arterial narrowing, symptoms and overall cardiovascular risk. Options may include:

  • Lifestyle changes: Dietary modifications, smoking cessation and management of cardiovascular risk factors.
  • Exercise: A supervised walking programme to improve circulation.
  • Medications: Drugs to manage PAD and associated risk factors.
  • Procedures or surgery: Interventions to restore blood flow in cases of severe arterial blockage.
