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.

Dementia Is Directly Linked To Obesity And High Blood Pressure: Study

Updated Jan 26, 2026 | 07:36 PM IST

SummaryYour weight can affect multiple aspects of your health, whether it is the functioning of a crucial organ such as the heart or your mental capacity. A new study revealed that obesity is directly linked with not just high blood pressure, but also dementia. Here is what you need to know

Your weight not only affects your heart health but also your brain health. A recent study published in the Journal of Clinical Endocrinology & Metabolism has revealed a powerful connection between your body weight, heart and brain.

After studying over 500,000 people, scientists discovered that having a high Body Mass Index (BMI) can nearly double your chances of developing brain-related illnesses later in life, which confirms that being overweight and having high blood pressure are not just general health concerns, they are direct causes of dementia.

How Does Your Weight Affect Brain Health?

The study focused heavily on vascular dementia, a specific type of memory loss that occurs when the brain is damaged because of a lack of blood flow.

Think of your blood vessels like a system of pipes. If those pipes are narrowed or blocked due to weight-related issues, the "engine" (your brain) doesn't get the fuel it needs. Over time, this lack of oxygen and nutrients leads to permanent brain damage and the loss of memory and thinking skills.

Researchers found that high blood pressure, often caused by carrying extra weight, is the main "middleman" in this process. Blood pressure is measured with two numbers, and both play a part in brain health:

Systolic

This is the pressure when your heart beats. It accounts for about 18 percent of the link between obesity and dementia.

Diastolic

This is the pressure when your heart rests between beats. It accounts for about 25 percent of the link. When these numbers stay high, they constantly "batter" the delicate vessels in the brain, causing them to weaken or clog.

How Weight Affects the Brain

Beyond just blood flow, a high BMI impacts the brain in several other ways:

Increased Inflammation

Obesity often causes the body to be in a constant state of "alarm" or inflammation. This can irritate the immune system and eventually damage brain cells.

Metabolism Issues

When the body struggles to process energy and food properly, it changes how the brain uses energy, which can lead to cognitive decline.

Heart Strain

A heart that has to work harder to pump blood through a larger body eventually becomes less efficient at sending blood all the way up to the brain. Your heart essentially has to do twice as much work as it would at a lower weight.

Can Preventing Obesity Help Dementia?

The most encouraging takeaway from this study is that dementia isn't always a matter of bad luck or "old age." Researchers call this an unexploited opportunity.

By managing your weight and blood pressure early in life, through a healthy diet, consistent exercise, and good sleep, you are essentially "dementia-proofing" your brain. The researchers suggested that intervening early, possibly even with weight-loss medications before symptoms start, could be a key strategy for protecting brain health in the future.

How Much Does Obesity Affect Worldwide?

According to the World Health Organization, one in eight people in the world are living with obesity. In 2022, about 2.5 billion adults were overweight. Causes of it vary, from things like diseases or chronic conditions, to the kind of food that is available to consume.

You Can Stop A Heart Attack With This Medicine, Cardiologist Reveals Heart Attack 101

Updated Jan 26, 2026 | 07:35 PM IST

SummaryHeart attacks are much more common than we realize. One person dies every 34 seconds from a cardiovascular disease and is one of the leading causes of deaths for men and women. However, do you know how to deal with one if it happened to you or someone near you?

Heart attacks need immediate intervention and Dr. Balbir revealed one medicine that can save a life when this happens: Aspirin. In an interview with HealthandMe, Dr. Singh revealed that one does not need fancy equipment to help a person having a heart attack.

“If the history of the family history or cholesterol or diabetic. This patient is at risk, so what is the medicine if you get such a symptom? Aspirin.”

What Medicine Can Help a Heart Attack?

Dr. Singh points out that if you or someone near you begins to experience symptoms of a heart attack, such as heavy chest pain, pressure, or unexplained sweating, taking a dissolvable aspirin immediately can be a lifesaver.

By dissolving a tablet (like Dispirin) in a glass of water and drinking it, the medicine dissolves into the bloodstream much more quickly than simply ingesting it.

Aspirin works by thinning the blood and preventing further clotting in the arteries, which can stop a heart attack from getting worse before medical professionals arrive.

Other Preventative Measures To Take For Heart Attack

Before medical professionals arrive, performing CPR can also help save a person's life; however, one must know the right way to do CPR.

While speaking to HealthandMe, Dr Singh mentioned a viral video where a person collapses and someone attempts to give them CPR while they are still sitting in a chair, notng that this was 'a dangerous mistake' and people should steer clear away from such false videos.

He explained that you cannot perform CPR on someone who is sitting up as the body must be positioned correctly for the heart and lungs to receive the benefit of the chest compressions.

Without the proper technique, blood will not reach the brain and your efforts will not help the patient. Understanding the proper sequence of events is the difference between a failed attempt and a saved life.

Step 1: The Importance of Positioning

If someone collapses, immediately place them flat on their back on a hard floor. You need the ground's resistance to pump the heart manually. In this position, the heart is "sandwiched" between the rib cage and spine. On a soft bed, your presses will fail to squeeze the heart effectively.

Step 2: Focus on the Heart First

Dr. Singh emphasizes that restarting the heart is the absolute priority. Place both hands in the center of the chest and use your body weight to press firmly. By pushing the rib cage toward the spine, you force the heart to pump. Often, once circulation starts, the patient begins breathing again spontaneously.

Step 3: The Proper CPR Sequence

If the person doesn't wake up, begin a rhythm of three chest presses followed by one mouth-to-mouth breath. Lock your elbows and press hard to ensure the heart is being squeezed between the bones. This specific cycle keeps oxygenated blood moving to the brain, preventing permanent damage during a cardiac emergency.

How Common Are Heart Attacks?

According to the Centers for Disease Control and Prevention, heart attacks claim a life every 34 seconds. In 2023, it caused nearly 920,000 deaths, one in every three recorded. Hence it is important to know not just the ways to help when someone has a heart attack but also how to prevent them.
