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.

Starving Cancer Or Weakening The Patient? Understanding The Truth About Sugar And Cancer

Updated Jun 26, 2026 | 12:14 PM IST

Summary​If a person completely stops eating carbohydrates, the body starts producing glucose on its own. This means the cancer cells still receive fuel, but the patient’s body becomes weaker day by day.
Starving Cancer Or Weakening The Patient? Understanding The Truth About Sugar And Cancer

There is a growing belief that ‘sugar feeds cancer.’ Because of this, many people think that stopping sugar and carbohydrates completely can starve cancer cells and help defeat the disease. However, the trend may have side effects. This half-truth is becoming dangerous for many patients. This trend is making it even more difficult for patients to cope with the side effects of chemotherapy.

This fact is not entirely unscientific, but it is incomplete. In 1924, the German scientist Otto Warburg found that cancer cells consume more glucose than normal cells. This phenomenon is known as the Warburg Effect.

This finding has subsequently been validated in numerous studies. This is also the reason why cancer cells appear clearly in PET-CT scans. They absorb glucose-like substances more aggressively than normal cells. But this does not mean cancer can be “starved” by reducing sugar in food.

Why The Body Still Needs Glucose?

Glucose is an essential fuel for the human body. The brain, heart, red blood cells, and immune system all depend on it.

If a person completely stops eating carbohydrates, the body starts producing glucose on its own. It breaks down muscles and proteins to make energy. This process is known as gluconeogenesis. This means the cancer cells still receive fuel, but the patient’s body becomes weaker day by day. This condition is described as ‘cancer cachexia.’

In this condition, body weight and muscle mass reduce rapidly. Such patients often cannot tolerate chemotherapy and surgery properly. In some cases, their protein levels and white blood cell counts had dropped too much.

As a result, doctors had to delay treatment, reduce medicine doses, or even stop some treatment cycles. Irony is painful. In trying to starve cancer, patients sometimes end up weakening their own bodies so much that proper treatment becomes difficult.

In my clinic, I see it almost every week. In such a case, a cancer patient walks in visibly frail. She almost had lost several kilograms over the past month. When I asked about her diet, her IT professional son said that she has cut out sugar entirely. The reason behind this was the same reel-based knowledge about sugar and cancer cells. His son strictly follows this half-truth. Due to her weakness, we had to push back her treatment for a few weeks.

What Cancer Patients Should Eat

We simply suggest avoiding foods that rapidly increase blood sugar levels. These include refined sugar, sweets, soft drinks, maida, and highly processed foods. We advise cancer patients to eat complex carbohydrates, whole grains, pulses, vegetables, healthy fats, and enough protein. The best way is not to cut sugar entirely, but to lower the glycemic load.

Will Fasting help?

Some animal studies have shown the benefits of fasting during cancer treatment. However, there is still not enough evidence in humans. For patients who are already weak or losing weight rapidly, long fasting can become harmful.

The Goal Is to Stay Strong During Treatment

Cancer cells use more glucose, but starving the body cannot stop cancer. If you want to help your body, then avoid refined sugar and junk food, but continue eating balanced meals. Because sufficient protein and calories are extremely important. Practising long fasting without medical advice is harmful. The goal should be to keep the body stable and strong, not weak.

The purpose of cancer nutrition is to nourish the patient, not to starve them. Proper nutrition helps the body tolerate treatment and fight disease more effectively. What is needed is to reduce the intake of refined sugar and foods with a high glycemic index, not to declare every carbohydrate an enemy. After all, one cannot win the battle against disease by weakening the body.

New Oral GLP-1 Pill Delivers Major Weight Loss In Just 36 Weeks

Updated Jun 26, 2026 | 07:00 AM IST

SummaryA new oral GLP-1 drug, aleniglipron, helped participants lose up to 12% of their body weight in 36 weeks. Researchers say the pill could offer a more accessible alternative to injectable weight-loss medications.

A new oral weight-loss drug is showing promising results for people living with obesity or who are overweight. In a phase II clinical trial published in Nature Medicine, participants taking the experimental medication aleniglipron lost up to 12% of their body weight over 36 weeks.

The study included contributions from Robert Kushner, MD, professor emeritus of medicine at Northwestern University and a longtime expert in obesity treatment.

Aleniglipron belongs to the GLP-1 family of drugs, the same class as popular medications such as Ozempic and Wegovy. These treatments help people lose weight by mimicking a natural hormone that reduces appetite, increases feelings of fullness, and helps regulate blood sugar levels.

What makes aleniglipron different is that it comes in pill form. Most currently available GLP-1 medications require injections and often need special storage, which can make them less convenient and more difficult for some patients to access.

Researchers believe an oral option could make treatment easier for many people. Because aleniglipron is a small-molecule drug—meaning it is chemically manufactured rather than peptide-based—it can be produced more efficiently and potentially at a lower cost.

“Aleniglipron is different because it’s a small molecule that can be taken with or without food,” Kushner said. “Most medicines people take every day, from aspirin to blood pressure drugs, are small molecules. That also creates opportunities to combine it with other treatments in the future.”

If further studies confirm its safety and effectiveness, aleniglipron could offer a more convenient alternative to injectable GLP-1 medications and help expand access to obesity treatment.

Why Is GLP-1 Drug A Medical Breakthrough?

Dr Shubham Vatsya explains that it took 20 years of research for scientists to come up with these medicines. This drug underwent proper lengthy trials, and have been approved by the US Food and Drug Administration (FDA), "which is not obtained by giving any bribe".

He also noted that when a person is not able to lose weight, Ozempic and drugs alike give a "head start" to them, along with a hope.

Talking about side effects, he says that every drug has its side effects, this is where a doctor's role comes in.

"Now, the person who is not able to lose weight, if you tell him 'you hit 100 kg bench press', he will break his shoulder. He needs a kickstart somewhere. This is what weight loss drugs allow," he says.

He also points out that the scientists who made GLP-1 agonists got a Nobel Prize, which "cannot be a scam". This is what makes weight loss drugs truly different.

What Are GLP-1 Drugs?

GLP-1 Drugs stand for Glucagon-like peptide 1, a naturally occurring hormones that helps regulate blood sugar and appetite after eating. It was first identified almost 50 years ago and scientists have since uncovered its role in type 2 diabetes.

How AC Exposure Causes Neck And Back Stiffness

SummaryCold air rarely works alone. Bad posture, sitting too long, skipping exercise, and not stretching enough all add to the problem.

Air conditioners feel great when the weather turns hot and sticky. Most of us spend hours under one, at home, at work, or even on long drives, and it barely crosses our minds. But sitting in cold air for too long can quietly leave your neck and back feeling tight and sore. AC isn't going to cause a serious spine problem on its own, but it can tighten up your muscles and make existing pain worse.

Why Does This Happen?

Muscles function optimally when they are relaxed and warm. As soon as the cold air comes into contact with them, the body automatically starts tightening them as it seeks to retain its warmth. When this occurs in places such as the neck, shoulders, and lower back regions, there is a chance that these muscles will get sore and stiff. This condition worsens even more if the cold air continues to blow in the same spot for hours, especially while sleeping or sitting at a workstation.

What It Does To Your Neck And Back

Your neck and back rely on several muscles to keep you upright and moving properly all day. Cold air can slow blood flow to these muscles, which makes them tense up more easily. That's why people often wake up with a stiff neck after sleeping under an AC vent or feel upper back pain after a day in a freezing office. If you already deal with something like cervical spondylitis or chronic back pain, cold air can make those symptoms flare up even more.

It's Not Just The AC

Cold air rarely works alone. Bad posture, sitting too long, skipping exercise, and not stretching enough all add to the problem. Picture sitting at a computer for hours in a chilly office: that's tense muscles and poor posture combining at the same time, which makes stiffness and pain even more likely.

Simple Ways To Avoid It

A few small changes can make a real difference: keep the airflow away from your neck and back, set the temperature to something comfortable rather than freezing, get up and stretch every so often, drink enough water, and keep a light sweater or shawl nearby if it gets too cold.

AC keeps us comfortable when it's hot outside, but too much cold air for too long can leave your neck and back stiff and achy. A little attention to airflow, posture, and movement throughout the day can help you stay comfortable without paying for it later.
