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.

Unlike most serious medical conditions, where outcomes depend almost entirely on what happens inside a hospital, cardiac arrest is different in one important respect: the person with the greatest power to change what happens next is almost never a doctor. It is whoever is standing closest. The heart can be restarted. Brain damage can be prevented.

India records more than 700,000 cardiac arrest deaths each year. Across South Asia alone, an estimated 5.5 million cardiac arrests occur annually. What separates a death from a recovery is not the sophistication of the care that eventually arrives. It is what any individual knows to do in the minutes before it does.

Not a Heart Attack. Something Faster

Sudden cardiac arrest is frequently confused with a heart attack, but the two are different events. A heart attack occurs when a blocked artery cuts off blood supply to the heart muscle. Cardiac arrest is categorically different: the heart stops beating entirely, and with it, all circulation to the brain and body ceases. A person can have a heart attack and still have a pulse.

In cardiac arrest, there is none. Every minute without CPR or defibrillation reduces the chance of survival by roughly 10 to 12 percent. In India's major cities, an ambulance takes between 15 and 20 minutes to arrive; in rural areas, over 60 minutes. These numbers place the first line of response where it has always been: with whoever is already in the room.

India's Distinct Risk Profile

The epidemiological picture in India has a distinctly local character. Data from South India show that the average cardiac arrest victim is 48 years old, predominantly male, and often without any prior diagnosis of heart disease. Lifestyle factors including physical inactivity, smoking, and alcohol consumption are consistent contributors, particularly among younger patients.

Perhaps most significant, 41 percent of autopsied patients with confirmed cardiac muscle damage showed no severe arterial blockage. Standard cardiovascular risk screening, designed primarily to detect blocked arteries, may therefore be missing a meaningful portion of those most at risk in India's population.

The Most Solvable Gap

The most immediate opportunity lies not inside the hospital but in the space between a collapse and an ambulance. Only 1.3 to 9.8 percent of bystanders in India attempt CPR during a cardiac emergency, and fewer than 15 percent of urban Indians have received any formal training. These figures are the primary reason India's survival rate for out-of-hospital cardiac arrest sits below 2 to 3 percent.

CPR requires no equipment and no medical degree. Steady chest compressions from anyone nearby can sustain blood flow to the brain until professional help arrives. Schools, workplaces, residential societies, and places of worship each represent a real and scalable training opportunity.

Where public health frameworks establish the groundwork, private sector partners have the infrastructure to extend that reach across the country. This is precisely the kind of challenge that structured public-private collaboration is designed to meet.

The Opportunity Ahead

Cardiac arrest incidence in India is projected to rise by 30 percent over the next decade as diabetes and hypertension rates continue to climb. That is a known trajectory, which means it is also a manageable one. AI tools now predict cardiac arrest up to 24 hours in advance using routine ECG data, and these technologies are already being developed with India's specific healthcare constraints in mind. What those tools ultimately do, however, is buy time.

The biological window of the first few minutes will always depend on whoever first responds to the patient. The country's greatest lever is not a device or a drug. It is an informed bystander who takes immediate action.

The word dialysis can stir up anxiety and fear for many. It's often seen as a sign of life never being the same again or it's considered a "last resort. I see many patients every day who assume that dialysis is their only choice. In fact, dialysis is a life saving therapy which takes over some of the functions of the kidneys which are unable to perform them properly. Knowing about the dialysis that it will require in the future, how dialysis works, and whether it can be delayed or avoided will help you avoid unnecessary anxiety and make informed decisions.

The kidneys are incredible organs that constantly filter out excessive fluid, toxins and waste products from the blood and help to keep the body's electrolyte balance, blood pressure and red blood cell production in check. As kidney function decreases substantially, these functions are disturbed and allow the build-up of harmful substances in the body. Dialysis mimics some of these filtering functions, and works to keep a patient healthy when their kidneys no longer do so.

Dialysis is not started just because of a laboratory value as is often thought. Many people think that dialysis is meant as a next step when kidney function drops below a certain percentage. But it depends on the results of kidney function tests, symptoms, and fluid overload, as well as electrolyte problems and patient clinical condition. Some people with an advanced stage of CKD may be able to do just fine and have no indication of needing dialysis for months; others might need urgent dialysis in case their kidneys are failing very quickly or they develop very serious complications that put their life at risk.

The most frequent indications for initiation of dialysis are: very high potassium levels, symptoms of fluid overload such as breathlessness, nausea and vomiting caused by accumulation of toxins, confusion, extreme tiredness, loss of appetite or condition where the dialysis cannot be managed with medication alone. In these cases, dialysis is not a choice but a lifesaver.

How The Two Main Types Of Dialysis Work?

There are two types of dialysis: In hemodialysis, the blood is pumped through a dialysis machine that removes waste products and excess fluid from the blood and returns the cleaned blood to the body. It's typically done three times a week in a dialysis center, but a few patients have home dialysis as an option. The process is usually a four hour per session process.

Another option is peritoneal dialysis, which involves using the patient's own abdominal lining to filter the blood. The abdominal cavity is filled with a cleansing solution, waste products and excess fluid are carried in to the solution through a permanent catheter, and the solution is drained. This treatment is often available at home and can provide a patient with more flexibility and independence. Medical suitability, lifestyle, home support and patient preference will all influence the decision on whether to undergo hemodialysis or PD.

Can Kidney Disease Be Slowed Or Dialysis Delayed?

A major concern patients have is if they can avoid dialysis altogether. The answer is dependent on the cause of kidney disease and the timeliness of diagnosis. However, in many cases, the kidney disease is a progressive condition over many years and there is a chance to slow the progression of the disease with appropriate medical treatment and lifestyle changes. Well managed diabetes and hypertension, avoiding unnecessary pain killers like non-steroidal anti-inflammatory drugs (NSAIDs), healthy weight, salt reduction in the diet, smoking cessation and frequent visits to a nephrologist can have a huge impact on slowing the deterioration of the kidneys.

An early diagnosis is very important. Sadly, a major drawback about chronic kidney disease is that most of the time, people don't have any symptoms in the initial stages of the disease. People are often diagnosed when they have significant kidney damage already. Routine screening is particularly important for those with diabetes, hypertension, cardiovascular disease, obesity and a family history of kidney disease. A number of simple blood and urine tests can detect kidney disease before symptoms occur.

Acute Kidney Injury And Chronic Kidney Disease Are Different

It is also crucial to differentiate acute kidney injury from chronic kidney disease. Acute kidney injury can occur if the kidneys become severely dehydrated, if the body be

“It’s only because I use my phone so much” We all know the excuse. It’s true that texting too much or using your hand in a certain way when holding your phone can be irritating and temporary. But not all your symptoms are the screen’s fault! Symptoms like tingling, burning or pins-and-needles may be due to a pinched or irritated nerve.

When Tingling And Numbness May Point To A Nerve Problem

A familiar example of such a condition is carpal tunnel syndrome, wherein pressure gets on the median nerve at the wrist, causing finger and hand numbness and tingling of your thumb, index and middle finger as well as part of ring finger, which are usually felt mostly at nighttime, or when you’re using the phone for too long.

An alternative would be compression of the ulnar nerve leading to symptom production with the little and part of the ring finger. Remaining with a bent elbow for prolonged durations can lead to increased symptoms, for example if using a telephone.

The Problem May Actually Start In The Neck

The pain doesn't always come from the hand. We could have some irritation of the nerve from a little higher up, right to from the neck. Problems with the cervical spine can be referred around the neck, and down the arm and into the hand as pain, and tingling or numbness or weakness.

That’s why just cutting back on screen time won’t help if an nerve issue is also going on. A second common error is to let your numbness progress so much that the cause becomes obvious before looking for medical care. Initial symptoms often come and go after the amount of time your nerves are compressed and can be worse if your nerves are compressed while you sleep or play an activity. Eventually, if nerve compression worsen, your symptoms may occur more often and may be paired with a weakness of the hand, or problems with the more precise dexterity manoeuvres.

Dropping Objects Or Weak Grip Are Warning Signs

Warning signs People also need to be aware of early signs of damage like dropping objects; problems with buttoning a shirt; having weakened grip strength or feeling like your hand feels weak when you hold something tight; or an ongoing general weakness. Those should never be ignored. There can be a link with phones because you hold your hand in the one position when holding and looking at it for a while your wrist, your elbow, your neck. But the problem isn't necessarily the phone itself.

Whether it is a repetitive motion or it comes on from something that has already occurred such as finding out you have diabetes or even have an already injured and pinched nerve in your wrist or at your elbow or even at your shoulder. Some simple stretches, an altered grip, keeping your elbow bent at just about 90 degrees and trying not to bend your wrist way backward will all work to your benefit.

When Numbness Needs Medical Evaluation

If numbness continues or weakness is increasing, pain is intense, or the sensations spread from the neck into the arm, you may need to see a physician for further examination, including possible nerve conduction studies, imaging, or blood tests based on their findings.

Not all sensations or tingling in your hand are "phone related", although it might seem obvious. A perceived annoyance can occasionally be the start of significant nerve compression requiring evaluation.
