Sleep changes as we age. When we were kids, we needed 10 to 12 hours of sleep, for teens it is eight to 10 and it decreases to seven to nine as we reach adulthood. But there is always a lack of urgency when it comes to sleep and young adults, many of whom prefer staying up and doing different activities. According to the Centre of Disease Control and Prevention, many national surveys show that about 37% of men, and 39% of people from the age of 45 to 64 reported not getting enough sleep.

Many people in America don't sleep the right amount. This means they either sleep too long or not long enough. But what happens to your body when you do not sleep enough? You just feel tired right? No, when you don't get this much sleep, your body can get stressed. This can make you more likely to get sick. A study published by the JAMA Network Open Sleep Trajectories and All-Cause Mortality Among Low-Income Adults showed that people who don't sleep the right amount have a higher chance of dying early. It's like your body needs that time to rest and fix itself. Without enough good sleep, things can start to go wrong. So, getting the right amount of sleep is super important for staying healthy.

How Was The Study Done?

Scientists wanted to see how sleep habits affect people's health over many years. They looked at almost 47,000 people who were between 40 and 79 years old. They asked them about their sleep habits when the study started, and then again, a few years later. The scientists wanted to see if people's sleep habits changed. They divided people into groups based on if they started with too much or too little sleep, and if their sleep changed over time. For example, some people started sleeping a lot but then started sleeping very little. This helped the scientists see how different sleep patterns affected people's health. They wanted to see the long-term effects of sleep.

The study found that people who had sleep habits that changed a lot had a higher risk of dying early. This means if you started sleeping too much and then switched to sleeping too little, or the other way around, you were more likely to die sooner. They also found that these people had a higher risk of heart problems. The risks were even higher for some groups of people, like white adults and people with higher incomes.

Sleep Deprivation And Its Effect On The Body

If you often doze off when you are sitting and reading, watching a movie, talking to someone, sitting quietly after lunch or even during a few minutes of traffic, you may be sleep deprived according to the National Heart, Lung, and Blood Institute. They explain how sleep deprivation can cause issues with learning, focusing and reacting to certain things. The symptoms of sleep deprivation in kids differ a little as they might be overly active and have trouble paying attention to certain things. If you are experiencing sleep issues, make sure to speak to a healthcare professional who will help you identify the issues and direct you towards the treatment or changes you must make. Here are some ways sleep helps your body.

Repairs Your Heart

Good sleep allows your heart and blood vessels to heal. This keeps them strong and healthy, reducing the risk of heart problems.

Controls Hunger

Sleep helps balance your hunger hormones, so you don't feel too hungry. This helps prevent eating too much and keeps your weight healthy.

Manages Blood Sugar

Proper sleep helps your body use insulin correctly. This lowers the chance of high blood sugar, which can lead to diabetes.

Supports Growth

Deep sleep releases growth hormones, helping kids and teens grow. It also repairs body tissues, which is important for everyone.

Boosts Immunity

When you sleep well, your body's defense system gets stronger. This helps you fight off germs and stay healthy.

For decades, cardiologists have noticed a clear seasonal trend. Heart attacks tend to rise during the winter months. Patients who already have heart conditions often see their health decline in the cold season, requiring more frequent and longer hospital stays. As winter approaches, pollution levels spike dramatically, making breathing more difficult, and for good reason.

Multiple factors combine to create this seasonal risk. We spoke to Dr. Vikash Goyal, Senior Cardiologist at Paras Health, Gurugram, to understand why chest pain becomes more common in winters.

Why Does Winter Trigger More Heart Risks?

Traditionally, this increase in heart-related issues has been linked to the body’s response to cold temperatures. Winter causes blood vessels to constrict and can lead to higher blood pressure, while reduced sweating may cause salt to build up in the body.

Less physical activity, along with a tendency to eat heavier, richer foods, adds to weight gain and raises blood sugar and cholesterol. Together, these factors increase the workload on the cardiovascular system, contributing to the rise in cardiac events during the winter months.

How Does Winter Pollution Trigger Chest Pain?

One constant in North Indian winters is a sharp rise in air pollution that comes alongside dropping temperatures. As the air cools and circulation slows, a thick layer of smog lingers over many cities. This pollution is a mix of vehicle emissions, construction dust, industrial smoke, and seasonal crop stubble burning. The simultaneous rise of air pollution and winter cardiac hospitalizations is too pronounced to ignore.

Dr. Vikash Goyal explained that air pollution has a significant but often overlooked effect on heart health. The heart relies on clear blood flow to support all major organs. When polluted air enters the lungs, tiny particles enter the bloodstream, triggering inflammation throughout the body. This narrows and stiffens blood vessels, forcing the heart to work harder while reducing oxygen supply to vital organs like the brain and kidneys.

He said, “This can lead to headaches, fatigue, dizziness, or worsening kidney function. During winter, the combination of cold temperatures and trapped smog thickens the blood and raises blood pressure, putting extra strain on the heart.” This explains why chest pain, breathlessness, and other cardiac issues increase during winter pollution season. Protecting yourself from polluted air isn’t just about lungs—it’s about safeguarding your whole cardiovascular system.

How Do PM2.5 Particles Harm The Cardiovascular System?

According to the World Health Organization, PM2.5 particles entering the bloodstream can cause multiple harmful effects on the heart. They trigger inflammation, destabilize cholesterol plaques, and increase the risk of plaque rupture, a common cause of heart attacks. They also create oxidative stress, producing free radicals that damage blood vessels and speed up atherosclerosis. Additionally, PM2.5 thickens the blood and makes platelets stickier, raising the chance of clots forming in blood vessels.

How To Protect Your Heart During Winter Pollution?

To reduce the impact of winter pollution on your heart, limit outdoor exposure on high-pollution days, wear N95 or N99 masks when going out, and use air purifiers and humidifiers indoors. Stay hydrated, eat foods rich in antioxidants, and keep an eye on your health.

If you notice persistent chest pain, tightness, or other concerning symptoms, seek medical help immediately.

Receiving a cancer diagnosis is scary, but what often causes greater harm is the delay in finding the disease and starting treatment. Many patients visit doctors only when symptoms become too obvious to ignore, by which time the illness has already advanced and is far harder to control. In most cases, cancer is caught late not because it hides well, but because people skip routine screenings.

In an Instagram video shared on November 6, Dr Jayesh Sharma, consultant surgical oncologist at ITSA Hospitals, spoke about four key tests that can help detect cancer early and reduce the number of late-stage cases.

4 Tests That Help Catch Cancer Early

Dr Sharma explained that there are four screenings everyone should consider. He noted that these tests can help identify cancer at the very first stage, when abnormal cells have formed but have not yet begun to spread. Detecting it at this point allows doctors to remove the cells completely, giving patients an excellent chance of recovery.

Mammography

Dr Sharma advised getting a mammogram once around the age of 40. He mentioned that while yearly tests are often suggested, most people do well with a screening every two years.

Cervical Cancer Screening

Cervical cancer remains one of the most common cancers in women. According to Dr Sharma, the Pap smear is a reliable way to catch early changes in cervical cells, even before symptoms appear.

Stool Test

He also recommended a stool test as a simple way to look for signs of stomach cancer. The earliest sign of trouble in the stomach is often hidden bleeding, which can be picked up through this test.

Chest CT Scan

For people who have been heavy smokers over many years, Dr Sharma suggested a chest CT scan. This group faces a higher chance of lung cancer, and a scan can help identify changes in the lungs at an early stage.

Symptoms Of Cancer

Warning signs of cancer can appear in many ways, and the symptoms usually depend on which part of the body is involved.

Some broad symptoms that may point to cancer, though they can occur in many other conditions as well, as per Mayo Clinic include:

• Fatigue that does not improve
• A lump or thickened area you can feel beneath the skin
• Unexpected weight loss or gain
• Changes in the skin, such as darkening, redness, yellowing, slow-healing sores, or new changes in moles
• Altered bowel or bladder habits
• A cough that lingers or ongoing breathing trouble
• Difficulty swallowing food
• A rough or hoarse voice
• Regular indigestion or discomfort after meals
• Ongoing, unexplained joint or muscle pain
• Recurring fevers or night sweats without a clear cause
• Bleeding or bruising without explanation

When To Seek Medical Advice

You should contact your doctor if any symptom continues for a long time or gives you reason to worry.

If you feel fine but are anxious about your cancer risk, speak with your doctor about it. They can guide you on the screening tests or checks that may be suitable for you

Recent data from the Human Fertilisation and Embryology Authority show a sharp rise in the number of women opting for egg-freezing. Yet the subject remains clouded by many misunderstandings. The decision itself is not simple. It involves emotional questions, significant costs and the physical demands of treatment. One common misunderstanding is the belief that egg freezing can harm egg quality, when the procedure does not lower the inherent quality of the eggs you already have.

We got in touch with Dr Shaweez Faizi, Fertility Specialist, Nova IVF Fertility, Mangalore, who told us more about the same.

What Is Egg Freezing?

Egg freezing, also called oocyte cryopreservation, is a fertility option in which a woman’s eggs are collected, frozen, and kept for future use. The steps include taking hormones to help the ovaries produce multiple mature eggs, retrieving those eggs through a short clinical procedure, and freezing them through a rapid cooling method known as vitrification.

As per Healthline, the frozen eggs are then stored in liquid nitrogen. When pregnancy is planned later, the eggs are thawed, fertilized in a laboratory, and the embryo is transferred to the uterus.

How Egg-Freezing Works?

The journey begins with roughly 8 to 12 days of hormonal tablets and injections that help several follicles grow at once. Dr Shaweez Faizi told us that doctors then use an ultrasound-guided needle to retrieve the mature eggs under light anaesthesia. The eggs are preserved through vitrification. The medication does not pull eggs from future years. It acts only on that month’s cohort, which is why medical bodies consider the procedure safe and ethically sound.

Can Egg Freezing Lower Your Egg Quantity?

Dr Shaweez Faizi told us that egg-freezing does not drain your ovarian reserve for life. The process collects only the group of eggs that your body was already preparing to release in that month. Some women notice a short-term dip in AMH after the procedure, but this usually settles with time. The stored supply inside the ovaries remains unchanged.

For those unversed, AMH, or Anti-Müllerian Hormone, is commonly used to assess ovarian reserve, meaning the approximate number of eggs still present in a woman’s ovaries.

Anti-Müllerian Hormone and Reserve

AMH is often treated as a marker of ovarian reserve, though it naturally varies. Studies show that a small number of women experience a temporary fall in AMH after stimulation, followed by a return to baseline. Specialists usually advise repeating the AMH test a few months after retrieval to get an accurate picture.

Egg Freezing Success Rates

Age at the time of freezing and the number of eggs stored have the strongest influence on outcomes. Global data suggest that women under 38 who freeze about 20 eggs tend to have higher chances of a future live birth. Older women usually retrieve fewer eggs per cycle, and success rates decline. Indian clinics report a wide range of live-birth outcomes, depending on age and the number of usable eggs.

People with low AMH or diminished reserve will have fewer eggs from the start. The issue lies in the baseline biology, not in the freezing itself. Those who have had ovarian surgery, such as endometrioma removal, may have reduced reserve due to the operation and should plan their timing carefully.

Women facing chemotherapy or serious medical treatment should consult both oncologists and fertility specialists. The Indian Fertility Society recently issued guidance on handling low ovarian response and preservation choices.

Practical Steps For Those Considering Egg Freezing

Dr Shaweez Faizi shared a few practical steps for women considering egg freezing:

• Start with basic tests such as AMH, AFC and a hormonal panel.

• Ask detailed questions about expected egg yield for your age, the number of cycles you may need, and the clinic’s real success figures. Advertising often paints a brighter picture than the data.

• Plan financially for medication, scans, retrieval, freezing and long-term storage.

• Keep age in mind, as younger eggs are more likely to develop into healthy embryos.

• Choose established centres that follow national and international practice standards.

Egg-freezing is a recognised and safe method to preserve fertility options, but it is not a guaranteed path to pregnancy.

Costs, success rates and the number of cycles needed vary widely. As the service becomes more accessible in India’s metropolitan centres, careful counselling and realistic planning remain essential before you decide.
