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.
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.
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.

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

Being aware of personal and family cancer risk may be a critical component in women's knowledge and empowerment to make appropriate screening, prevention and treatment decisions.
Cancer treatment is fast evolving. Doctors are now focusing more on the person than the location or type of cancer and are considering the personal attributes of the patient and the disease. Genetic/genomic testing can complement this and can offer something more that could inform personalised cancer care.
Genetic testing screens for changes in the genes that could be passed down from parents. Some genetic mutations passed down from parents can make a woman more likely to get breast or ovarian cancer.
Having such a genetic change does not mean that a woman will develop cancer. This information will help her and her doctor discuss screening, monitoring and preventive action (if applicable) to reduce her risk.
This information may be useful for family members who could be at risk and should talk to their health care provider about their own risk.
There is a difference between genetic testing and genomic testing. Genetic testing is usually performed on blood or saliva to look for inherited changes or genetic predisposition. Genomic testing is usually performed on the tumour or blood to identify its molecular features to enable better understanding of its biology and biomarkers.
Cancer is not one disease and even two patients with the same type of cancer can have different biological characteristics, which can help doctors decide on the treatment and options that may be suitable for an individual patient.
Genomic testing could help to pinpoint features of a tumour that can be used to consider particular targeted treatments or other methods. But not all of them will be suitable or available to all patients based on the results of testing.
For women, knowing their family history and discussing any concerns with a doctor can be an important starting point. Genetic or genomic testing should not be done simply because it is available. A specialist may recommend testing based on factors such as family history, age at diagnosis and the type of cancer involved.
It is also important to understand test results correctly. Genetic counselling and discussions with an oncology specialist can help women understand what their results mean and what they do not mean.
Ultimately, genetic and genomic testing is not about predicting the future with certainty. It is about giving patients and doctors more information to make better-informed decisions.
As cancer care moves towards greater personalisation, the freedom to know your risk can become a powerful part of taking control of your health—helping women move from fear and uncertainty towards awareness, informed choices and personalised care.

World Mosquito Day, observed on August 20, raises awareness about mosquito-borne diseases such as dengue, malaria, Zika, yellow fever, and chikungunya and the health risks they pose.
Among these diseases, dengue remains a major public health concern, affecting people across regions worldwide throughout the year.

Dengue is typically associated with high fever, joint pain, and low platelet counts. However, severe dengue can affect the kidneys and lead to acute kidney injury (AKI).
Speaking to HealthandMe, nephrologists said kidney problems may not always cause symptoms early on, making monitoring particularly important in severe dengue.
Dr. Anupam Roy, Additional Director - Nephrology and Kidney Transplant, Aakash Healthcare Multi-Speciality Hospital, Dwarka, said that recovering from dengue requires careful fluid management, particularly in severe cases.
It is because the kidneys regulate fluids and electrolytes, and changes in circulation caused by dengue can temporarily disrupt their function.
Fever, vomiting, and poor fluid intake can cause dehydration, while severe dengue can cause plasma leakage. Both too little and too much fluid can create problems, making medical supervision important. In hospital, healthcare professionals monitor urine output and signs of dehydration, particularly in patients with complications or underlying health conditions.
After the acute phase, patients should gradually resume eating and drinking according to medical advice. Excessive fluid intake and self-medication should be avoided, particularly when medicines could place additional stress on the kidneys.
“So, it is the quantity issue that must be tackled,” Dr. Roy said.
According to Dr. Manoj Arora, Consultant Nephrologist, NephroPlus, a network of dialysis centers, warning signs include:
Some symptoms can overlap with severe dengue, including continuous vomiting, severe stomach pain, and bleeding.
Kidney injury is more likely in people with severe dengue or shock. Older people and those with diabetes, hypertension, obesity, or existing kidney problems may also face higher risk.
Seek medical attention for a drastic reduction in urine, new swelling, blood in the urine, worsening breathlessness, confusion, or continuous vomiting.
In hospitalized patients, monitoring is important when creatinine rises, electrolyte levels fluctuate — particularly potassium — or urine output continues to change.
Early recognition and appropriate management are key. Doctors may monitor:
Do not self-medicate or increase fluid intake without medical advice, particularly during severe dengue.
Reducing mosquito exposure and preventing mosquito breeding can help lower the risk of dengue.

Are you someone who can spend hours scrolling through short videos on Instagram, YouTube or TikTok? A new study suggests that watching preferred short videos may temporarily quiet brain regions involved in self-control and monitoring, offering a possible clue to why it can be so hard to stop.
Short Videos May Quiet Brain’s Self-Control Network
The research, published in the journal NeuroImage, found that watching preferred short videos may temporarily suppress activity in parts of the brain involved in cognitive control. This effect may also be linked to levels of the brain chemical glutamate.
The study focused on the dorsal anterior cingulate cortex (dACC) and dorsolateral prefrontal cortex (dlPFC). Both are key regions of the cognitive control network, which becomes active during tasks that require mental effort, attention and self-regulation.
Researchers from Zhejiang University in China found that both the dACC and dlPFC showed significant deactivation when participants watched preferred videos to completion, compared with less-preferred videos that were stopped early.
The liked videos significantly reduced activity in both brain regions linked to cognitive control. When participants watched videos they chose to continue, activity in the dACC and dlPFC fell below normal resting levels.
However, disliked videos showed a different pattern. Activity in the dACC remained close to normal, while the dlPFC was still suppressed. Meanwhile, the visual cortex remained active during both types of videos, suggesting the changes were linked to the viewing experience rather than simply looking at a screen.
The small study of 56 participants also examined whether resting levels of two important brain chemicals could help explain differences in how participants’ cognitive control networks responded during short-video viewing.
Glutamate is the brain’s main excitatory neurotransmitter, helping increase neural activity. Gamma-aminobutyric acid (GABA) is the brain’s main inhibitory neurotransmitter, helping reduce or regulate neural activity.
The researchers found that resting-state glutamate levels in the dACC were associated with the extent of brain deactivation. Higher glutamate concentrations were linked to less suppression of activity in both the dACC and dlPFC.
Functional connectivity between the dACC and dlPFC also increased during video viewing, particularly when participants watched their preferred videos.
The researchers said the findings provide new evidence that immersive viewing of preferred short videos can deactivate the cognitive control network and that individual differences in this response may be linked to glutamate metabolism.
They suggested that the findings could help improve understanding of how digital media consumption interacts with neurochemical processes involved in self-regulation and may offer insights into the neural mechanisms behind excessive short-video use.
The study, however. does not establish that short-video viewing directly causes a loss of self-control or addictive behavior.
Previous research has linked excessive short-video use with changes in attention, focus and mental well-being.
Studies in Nature Communications and research from the American Psychological Association suggest that highly stimulating, rapidly changing content may encourage constant novelty-seeking and make sustained attention more difficult.
Potential effects include:
Short videos are not inherently harmful, but excessive or compulsive scrolling can become a concern when it interferes with sleep, work, studies or daily life.
