We've all been there, you use the toilet, try to stand up, and suddenly your legs go numb. That odd pins-and-needles feeling can be surprising and uncomfortable. Though it might feel like a small inconvenience, it does have a scientific explanation. The numbness, also called transient paresthesia, happens when pressure blocks blood flow or presses on nerves in your lower extremities. It is normally harmless, but frequent occurrences can be signs of underlying health issues or poor toilet habits that must be addressed.

That weird numbness you experience after going to the bathroom is typically just a temporary annoyance, most often due to bad posture, straining, or sitting for an extended period. But if the numbness continues or gets worse, it is important to get medical guidance to make sure there are no underlying health issues. We discovered the top three reasons that could be responsible for this tingling and how can you avoid it? Let's dissect.

3 Reasons Your Legs Go Numb on the Toilet

1. You’re Straining Too Much

Struggling to push during a bowel movement can put excessive pressure on your abdomen and spine. This increased pressure can shift spinal discs, pressing against nerves that extend into your legs and feet. The result? A temporary loss of sensation, tingling, or weakness in your lower limbs.

Straining usually results from constipation, which in turn can be caused by a low-fiber diet, dehydration, or inactivity. If you notice that you're straining frequently, perhaps it's time to change your eating and drinking habits to help move your bowels more easily.

2. Inadequate Sitting Posture

The way you sit on the toilet can also be a cause of that numbness in your legs. Most people are prone to hunching over when they are using their phones, reading, or just focusing too intensely. But this position can compress nerves and blood vessels in your pelvis, causing tingling or numbness.

When you sit slumped forward, you cut off blood supply to the lower half of your body, compressing nerves that travel from your pelvis to your toes. That's why the numbness will often radiate past your thighs and into your toes.

3. Sitting for Too Long

The more time you spend sitting on the toilet, the higher your chance of getting numb legs. Protracted sitting continually puts pressure on the nerves within your lower limbs, slowing blood flow and leaving you with the familiar pins-and-needles feeling.

If you habitually stay on the toilet for a long time, either from digestive problems or distractions such as browsing your phone, you may find that there is more numbness over the course of time. If constipation is leaving you on the toilet longer than normal, diet changes can calm your system.

How to Stop Your Legs from Falling Asleep on the Toilet

Although periodic tingling is not a health issue, recurring numbness is a problem that needs to be addressed. Below are some professional-recommended ways of preventing it:

1. Proper Posture

Being seated with your knees higher than your hips can make all the difference. Sitting this way enables your colon to unwind, facilitating smooth bowel movements while minimizing pressure on the lower parts of your body.

Don't slouch, as this squishes nerves and blood vessels, making numbness more likely. If necessary, lean your back against the toilet tank or wall to keep your posture good.

2. Don't Spend Too Long on the Toilet

Specialists recommend five to ten minutes of toilet time per visit. If you are straining, stand up, walk around, and try later. Forcing the bowel movement can cause more damage than benefit, putting greater pressure on your spine and worsening numbness.

If constipation is a chronic problem, being hydrated and consuming fiber foods such as fruits, vegetables, and whole grains can get your digestive system back in working order.

3. Use a Toilet Stool

Raising your feet using a toilet stool may position your body for a more natural and strain-free bowel movement. A squatting position keeps the rectal canal open, minimizing the need to push and reducing the risk of leg numbness.

4. Try a Padded Toilet Seat

Hard toilet seats can restrict circulation in your lower body, increasing the risk of numbness. A cushioned or padded toilet seat can provide better support, improving blood flow to the legs and feet while reducing pressure on the pelvis.

When to Seek Medical Advice

While it's normal to have some numbness in your legs from time to time when sitting on the toilet, ongoing tingling or numbness in your lower extremities may be a symptom of an underlying medical condition. If you find yourself experiencing:

• Bathroom-use-independent frequent numbness
• Muscle weakness
• Pain or discomfort in legs or lower back
• Loss of bladder or bowel control

It's best to see a healthcare expert to exclude conditions such as nerve compression, circulatory disorder, or spinal condition.

Extremes of heatwaves and ozone pollution are intensifying, increasing heart- and lung disease-related deaths in India, according to a new study.

Heatwaves are associated with heat stress, dehydration, heat exhaustion, heatstroke, and cardiovascular strain, while ground-level ozone is a harmful air pollutant linked to heart and lung diseases and increased mortality.

Researchers from the Indian Institute of Technology (IIT), Kharagpur, found that surface ozone levels reach 85–110 micrograms per cubic meter (μg/m³) in northern India during heatwaves—far exceeding the World Health Organization (WHO) guideline of 70 μg/m³.

The study found that heatwaves significantly intensify exposure to toxic ground-level ozone, a harmful air pollutant linked to heart and lung diseases and increased mortality.

“In 2024 alone, ozone exposure during heatwaves was associated with 15,615 deaths from ischemic heart disease and another 10,898 deaths from chronic obstructive pulmonary disease (COPD),” said researchers Parambat Sangeetha of Kerala University of Fisheries and Ocean Studies and Jayanarayanan Kuttippurath of IIT Kharagpur in the paper.

Overall, ozone exposure during heatwave conditions was associated with more than 26,500 deaths in 2024, according to the study published in npj Clean Air. Before heatwave conditions, ozone exposure was linked to 490 deaths from ischemic heart disease and 342 deaths from COPD.

Why Ozone Levels Rise During Heatwaves

Surface ozone is not released directly into the atmosphere. Instead, it forms when sunlight triggers chemical reactions among existing pollutants—a process that accelerates during periods of extreme heat.

“Ozone is very harmful, while NO₂ (nitrogen dioxide) and HCHO (formaldehyde) directly damage the respiratory system,” the authors said.

How the Study Was Conducted

For the study, researchers combined two decades of temperature records from the India Meteorological Department (IMD) with satellite observations and global weather datasets to track ozone levels and the gases responsible for its formation.

Heatwaves between 2004 and 2024 were identified using standard temperature thresholds. The team identified 188 heatwave events over the two-decade period, with the most severe years—2010, 2016, 2019, and 2024—occurring after strong El Niño episodes.

The Western Himalayas recorded the sharpest long-term increase in ozone levels, exceeding WHO guidelines by 115 percent in 2024.

The researchers concluded that “coupled heat–ozone extremes are intensifying, requiring urgent integrated climate–air quality policy action.”

Regions Most Affected

Severe heatwave conditions predominantly affect:

• Jammu
• Rajasthan
• Gujarat
• Madhya Pradesh
• Punjab
• Haryana
• Chandigarh
• Uttar Pradesh
• Delhi
• Himachal Pradesh
• Vidarbha
• Maharashtra

The heatwave belt often expands further into:

• Uttarakhand
• Odisha
• Chhattisgarh
• Bihar

Impact on Lung and Heart Health

The study noted that chronic obstructive pulmonary disease (COPD) is highly sensitive to changes in temperature, humidity, and air quality.

Dr. Amit Kumar Mandal, Senior Director of Pulmonology at Paras Health, explained that extreme heat combined with pollution places significant stress on multiple organs.

“People often think heatwaves only affect the skin or cause dehydration, but when extreme heat combines with high pollution levels, the body starts functioning as if it is constantly under attack,” he told HealthandMe.

“The lungs are forced to work harder to filter hot, polluted air, while the heart simultaneously struggles to regulate body temperature. This invisible overload can quietly trigger inflammation, breathing distress, sudden BP fluctuations, and cardiac strain, even in people who otherwise consider themselves healthy.”

Warning Signs to Watch For

The expert noted that early symptoms are often subtle and may go unnoticed. Common symptoms seen during heatwave and pollution episodes include:

• Persistent tiredness
• Irritability
• Disturbed sleep
• Headaches
• Chest heaviness
• Unusual breathlessness

How to Reduce Health Risks

Recommended precautions include:

• Staying hydrated
• Avoiding direct sunlight during peak afternoon hours
• Wearing light cotton clothing
• Using masks in polluted areas
• Maintaining proper indoor ventilation.

The ancient practice of yoga may help improve fertility and hormonal health in women with Polycystic Ovary Syndrome (PCOS), now renamed Polyendocrine Metabolic Ovarian Syndrome (PMOS), according to three studies led by researchers at the All India Institute of Medical Sciences (AIIMS), New Delhi.

PCOS is a multifactorial condition affecting millions of women and involves a complex interplay of reproductive, metabolic, and psychological factors that can significantly impact quality of life.

The condition can increase the risk of serious health complications, including heart disease, diabetes, hypertension, infertility, and, in some cases, cancer.

The studies, led by Dr. Rima Dada, Professor at the Laboratory for Molecular Reproduction and Genetics, Department of Anatomy, AIIMS Delhi, recommend lifestyle modifications, including yoga, as a primary approach to managing the condition.

“Yoga presents a comprehensive strategy for addressing PCOS, targeting hormonal imbalances, OS, mitochondrial function, metabolic syndrome, microRNA regulation, cellular longevity, and mental well‑being. It exemplifies the potential of mind‑body medicine in the treatment of complex disorders,” the researchers said, in the papers.

The papers were published in the Journal of Ayurveda and Integrative Medicine, The International Journal of Ayurveda Research and the International Journal of Yoga.

Yoga Led To Improvements In Hormonal Balance

The three studies involved more than 100 women and followed participants for up to 12 weeks. Participants practiced Asanas (physical postures), Pranayama (breathing techniques), and Dhyana (meditation) for 90 minutes a day, five days a week. The results showed significant improvements across multiple health parameters.

Women with PCOS who participated in the yoga intervention demonstrated significant reductions in:

• Anti-Müllerian Hormone (AMH)
• Luteinizing Hormone (LH)
• Testosterone levels

“This hormonal balance has led to the restoration of menstrual cycles and improvements in hirsutism and acne, resulting in enhancements in physical appearance and psychological well-being,” the researchers stated.

Benefits Beyond Hormones

The studies also found that yoga helped regulate cellular oxidative stress, offering protection against DNA damage and epigenetic changes. Researchers also reported improvements in several metabolic markers, including reductions in:

• Glucose
• Fructose
• D-ribose
• Xanthine
• Cholesterol
• Triglycerides
• Body weight

These findings highlight yoga's potential to address key mechanisms underlying PCOS and support its use as a cost-effective, non-pharmacological, and sustainable therapy for managing the condition.

The studies also found that yoga helped alleviate symptoms of depression among women with PCOS, suggesting it may serve as an effective complementary therapy in managing the condition.

Researchers concluded that regular yoga practice could help prevent, delay, and manage PCOS symptoms.

What Is PCOS?

PCOS is a complex lifestyle disorder that appears to primarily affect the ovaries but is increasingly recognized as a systemic condition affecting multiple organs and body systems.

If not diagnosed and managed early, it can contribute to serious health complications, including non-alcoholic fatty liver disease (NAFLD), cardiovascular disease, hypertension, and Alzheimer's disease.

While treatments such as anti-androgen medications, insulin-sensitizing agents, and fertility therapies remain important, experts note that PCOS also has a strong psychosomatic component that can benefit from lifestyle and mind-body interventions.

From PCOS to PMOS

PCOS affects more than 170 million women worldwide. In May, it was officially renamed Polyendocrine Metabolic Ovarian Syndrome (PMOS).

The new name reflects a major shift in understanding the condition—from a predominantly gynecological disorder to a complex multisystem condition affecting several aspects of health. The term PMOS acknowledges that the condition affects:

• Endocrine health
• Metabolic health
• Reproductive health
• Dermatological health
• Psychological health

Back pain is one of the most common health complaints worldwide, affecting a large proportion of adults at some point in their lives. In most cases, it is caused by benign musculoskeletal issues such as muscle strain, poor posture, or disc-related problems, and it tends to improve with rest, physiotherapy, or simple medication. However, not all back pain originates from the spine. In some situations, pain felt in the lower back or flank region may be linked to underlying kidney conditions, including kidney cancer. As renal cell carcinoma often progresses silently in its early stages, symptoms may be delayed, making it important to recognise when back pain is unusual.

Why Kidney Cancer Can Cause Back Pain

Dr Raj Nagarkar, Chief Surgical Oncologist at HCG Manavata Cancer Centre, Nashik, said, "The kidneys are located deep in the upper abdomen, on either side of the spine, just below the rib cage. When a tumour develops in this region, it can cause pain through several mechanisms. As the tumour grows, it may stretch the kidney’s outer fibrous capsule, leading to a persistent, dull ache in the flank area between the ribs and hip. In some cases, fragile tumour blood vessels may bleed internally or form clots that obstruct urine flow, resulting in sudden, sharp pain that can resemble renal colic. Larger tumours may also press on surrounding nerves or structures, producing discomfort that may be mistaken for back or abdominal pain."

Unlike musculoskeletal pain, which typically improves with movement or rest, kidney-related pain is often constant, may worsen at night, and does not respond well to routine pain relief or physiotherapy.

Red Flags When Back Pain Needs Further Diagnosis

While back pain alone is rarely a sign of kidney cancer, certain accompanying symptoms should raise concern. One of the most important warning signs is blood in the urine, which may appear pink, red, or dark brown and can sometimes be intermittent. Persistent flank pain associated with a palpable mass under the ribs may indicate more advanced disease. Unexplained weight loss, ongoing fatigue, or a general sense of weakness can reflect systemic illness. Some patients may experience intermittent fever without infection, new-onset high blood pressure, or swelling in the legs and ankles due to impaired venous drainage. Anaemia-related symptoms such as dizziness, breathlessness, or pallor may also be present. When back pain persists beyond a few weeks and is accompanied by any of these features, further medical evaluation is strongly recommended.

Differentiating Musculoskeletal Back Pain from Kidney Cancer Pain

It is also important to distinguish kidney-related pain from common musculoskeletal back pain. Mechanical back pain is usually localised to the lower back, may radiate to the legs, and often begins after physical strain or injury. It tends to improve with rest, heat application, or physiotherapy. In contrast, kidney cancer pain is typically one-sided, located higher in the flank below the ribs, and develops gradually without a clear trigger. It is often persistent, may disturb sleep, and is not relieved by standard pain management approaches. Unlike spinal pain, it is more likely to be associated with systemic symptoms such as haematuria, weight loss, or fatigue.

Who Is at Higher Risk?

Certain individuals are at higher risk of developing kidney cancer and should be particularly attentive to persistent flank pain. Risk factors include smoking, which significantly increases exposure to kidney-damaging toxins, obesity, long-standing hypertension, chronic kidney disease or dialysis, and a family history of kidney cancer or genetic conditions such as von Hippel-Lindau disease. Occupational exposure to industrial chemicals like trichloroethylene or cadmium may also contribute to risk. When multiple risk factors are present, even mild or persistent symptoms should not be ignored.

Diagnosing Kidney Cancer

If warning signs are suspected, doctors typically begin evaluation with simple and non-invasive tests. A urine analysis can detect microscopic or visible blood, while blood tests help assess kidney function, anaemia, and calcium levels. Imaging plays a crucial role, with ultrasound often used as the first-line investigation, followed by a contrast-enhanced CT scan for detailed evaluation of tumour size and spread. In selected cases, a biopsy may be performed, although it is not always required before treatment.

Treatment and Outcomes

Treatment outcomes for kidney cancer have improved significantly in recent years. In early-stage disease, partial nephrectomy allows removal of the tumour while preserving healthy kidney tissue, often using minimally invasive or robotic techniques that support faster recovery. In more advanced cases, targeted therapies and immunotherapy help control disease progression and improve quality of life, with many patients able to maintain daily activities during treatment. For small, slow-growing tumours in selected individuals, active surveillance may be an appropriate option.

Listening to the Warning Signs

While most back pain is benign and related to musculoskeletal causes, persistent or unusual pain, especially when accompanied by symptoms such as blood in the urine, unexplained weight loss, or systemic changes, should not be ignored. Kidney cancer often develops silently, and early signs can be subtle. Unlike muscular pain, which is typically movement-related and self-limiting, kidney-related pain is deeper, more persistent, and often associated with other warning features.
