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.

Even a mild case of COVID-19 may trigger long-lasting eye problems, with new research revealing that persistent inflammation and nerve damage could be responsible for symptoms that standard eye tests often fail to detect.

The study, led by researchers at Linköping University in Sweden and published in Nature Communications, sheds light on why some COVID-19 survivors continue to experience debilitating vision issues months or even years after infection.

The research began after people who had recovered from mild COVID-19 sought medical help for persistent eye complaints. Many reported:

• Severe eye pain
• Light sensitivity (photophobia)
• Difficulty reading and focusing
• Extreme eye fatigue

Many participants said the condition significantly disrupted their daily lives, preventing them from working or continuing their education.

What the Study Found

Researchers evaluated 100 people who developed eye problems after mild COVID-19 but had never been hospitalized. Their symptoms had persisted anywhere from three months to three years.

The findings were compared with those of 32 people who had recovered from mild COVID-19 without developing eye symptoms.

Using advanced imaging and laboratory techniques, researchers identified several abnormalities that conventional eye exams failed to detect.

Persistent Inflammation and Nerve Damage

The study found evidence of:

• Long-term inflammation in the eyes
• Damage to nerves controlling multiple eye functions
• Abnormal immune activity involving T cells
• Changes in proteins found in tear fluid

Lead author Petros Moustardas, senior research associate at Linköping University, said the findings indicate that COVID-19 may trigger a severe immune reaction in the eyes, resulting in chronic inflammation and nerve dysfunction.

One of the most common complaints among participants was extreme sensitivity to light. Researchers found that their pupils were allowing too much light into the eyes because of impaired nerve control.

This abnormal pupil function was also associated with:

• Headaches
• Difficulty reading
• Trouble maintaining focus

An Unusual Eye Movement Disorder

The study also identified impaired coordination between the two eyes.

Some participants developed adult-onset strabismus—commonly known as crossed eyes—a condition that is rare in adults.

Researchers believe this occurred because COVID-19 affected the nerves responsible for controlling eye muscles.

A New Way to Diagnose COVID-Related Eye Problems

Because routine eye tests often miss these abnormalities, the research team developed two diagnostic models.

The first relies on specialized ophthalmic tests available at advanced eye clinics, while the second combines these examinations with tear fluid protein analysis to improve diagnostic accuracy.

Researchers hope these models will help doctors recognize COVID-related eye syndrome earlier and pave the way for future treatments.

"We found that the problems experienced by those affected were not detectable by standard tests. We had to perform specialised examinations to detect deviations. The puzzle pieces then fell into place, and we found explanations for the symptoms," said Neil Lagali, professor of experimental ophthalmology at Linköping University.

He added that while the findings provide important clues about how COVID-19 affects the eyes, more research is needed to develop effective treatments for those living with persistent vision problems.

Plant-based Vitamin D3 is often marketed as a healthier or superior alternative to traditional supplements, but doctors say that's not necessarily the case.

According to Dr. Murtaza S. Bagwala, Head of Emergency Medical Services at Saifee Hospital in Mumbai, existing research shows that plant-based Vitamin D3 is just as effective as conventional Vitamin D3 in increasing the body's vitamin D levels.

"Current evidence suggests that plant-based Vitamin D3 performs similarly to conventional Vitamin D3 supplements. For people who prefer vegan or plant-based products, it is a suitable alternative," he told HealthandMe.

Echoing this view, Dr. Sudhir Kumar, Neurologist at Apollo Hospitals in Hyderabad, said that plant-derived Vitamin D3—usually obtained from lichen, algae, or modern fermentation methods—provides an animal-free option without sacrificing effectiveness.

In a post on X, he noted that while plant-based Vitamin D3 is welcome news for vegans and those seeking cruelty-free supplements, both forms work equally well. He added that there is no medical need for people to switch if they are already taking conventional Vitamin D3 supplements.

India has approved its first plant-based Vitamin D3 (cholecalciferol) ingredient, a move that could expand options for food fortification and dietary supplements while addressing the country's widespread Vitamin D deficiency.

The Food Safety and Standards Authority of India (FSSAI) has cleared VITADEE Green, developed by Fermenta Biotech, for use in health supplements, nutraceuticals and food products.

The company stated that the ingredient is produced using an India-patented process and offers a sustainable, scalable and vegetarian-friendly source of Vitamin D3.

The approval allows Indian manufacturers to incorporate the ingredient into fortified foods, beverages and dietary supplements.

It is particularly significant for vegetarians and vegans, who have traditionally had limited access to Vitamin D3 because most supplements are derived from lanolin, a by-product of sheep's wool.

The approval also supports India's broader efforts to improve nutrition through food fortification, an area where experts say Vitamin D remains a major gap.

What Is Vitamin D3?

Vitamin D3, often called the "sunshine vitamin," is produced by the body when the skin is exposed to sunlight.

It helps the body absorb calcium, maintain healthy bones and teeth, and lowers the risk of fractures. In children, severe deficiency can lead to rickets, while in adults it increases the risk of osteoporosis, muscle weakness, and falls.

Beyond bone health, Vitamin D3 also supports immune function. Research suggests low Vitamin D levels may be associated with increased susceptibility to infections and higher levels of inflammation.

Who Should Take Vitamin D3 Supplements?

The experts said the key question is whether supplementation is needed, not whether the source is plant- or animal-derived.

"The source matters mainly for ethical, dietary or personal preference—not for efficacy," Dr. Sudhir said.

Dr. Bagwala cautioned against taking high-dose Vitamin D without medical advice, as excessive intake can raise calcium levels and increase the risk of kidney stones and other complications.

Yawning has a certain fact attached to it, which is without a doubt a reason for curiosity and amazement among people. Many of you must have noticed that when someone nearby yawns, you often end up yawning too. Even in some cases, a person yawns just after hearing the word yawn or watching someone yawn on screen.

Yawning itself is a natural physical process that involves taking a deep breath and stretching the muscles used for breathing. Some experts suggest that it may help increase alertness and leave us feeling refreshed. However, while scientists have proposed several theories about the purpose of yawning, one question continues to intrigue researchers: why are yawns so contagious?

Dr. Debanjan Pan, Consultant Psychiatrist at Saltlake Mindset, told Health and Me, "Contagious yawning may be linked to mirror neurons, which help us understand and imitate the behavior of others. Humans have survived by living in groups, and our brains are naturally wired to synchronize with the people around us. When we see someone yawn, the same neural networks in our brains may become activated, prompting us to yawn as well."

Yawning involves taking a very deep breath, which increases oxygen intake and stimulates several parts of the respiratory system. This deep inhalation can temporarily raise the heart rate and boost blood circulation to the spinal cord and the brain, making a person feel calmer and more relaxed afterward.

According to Dr. Pan, this sense of relaxation may also explain why yawning is contagious. When we see someone else yawn, the brain's empathy circuits, particularly those linked to mirror neurons, become active. As humans are highly social beings, we often unconsciously mimic the behaviour and emotions of people around us, causing a yawn to spread from one person to another.

But there might be a question: if yawning is contagious because humans are social animals and human brains are naturally wired to synchronize with the people around them, then why doesn't coughing and sneezing have the same effect?

Dr. Vikas Mittal, Director - Pulmonologist, CK Birla Hospital, Delhi, addressed this very issue and explained, "Yawning is different than coughing and sneezing. Coughing and sneezing are protective reflexes that protect you from irritants. They can be contagious, but that contagion comes after one or two days, not immediately as is with yawning. Yawning occurs because of the brain's automatic self-mirroring networks."

Dr. Mittal further added, "What it means is when somebody yawns, then your brain starts imitating that unintentionally. Not only yawning, but other emotions like a smile, laugh, and fear can trigger the same emotion in the people around you. This is because of the same brain's automatic self-mirroring networks."

Contagious yawning appears to be more than a simple reflex, offering insights into empathy, social bonding, and the human brain.
