NEW DELHI: A new study has mapped how different body parts communicate with each other under physiological stress, such as during exercise or sleep deprivation, which researchers say could one day help diagnose an illness earlier. Researchers at the University of Portsmouth and University College London, UK, said the study encourages a "whole-body" view of physiology, instead of focusing on isolated measurements such as heart or breathing rate. Using 'transfer entropy' -- a method of monitoring body signals -- a complex network of maps was created showing which body parts act as 'information hubs' under different stress conditions, the team explained. For example, during exercise, the heart -- which is working hard to pump blood to muscles -- receives the most input from other systems and therefore, "takes the lead" in helping the body adapt, the researchers said. Described in a study published in the Journal of Physiology, the maps "show that our body isn't just reacting to one thing at a time," said author Alireza Mani, associate professor and head of the network physiology lab at University College London. "It's responding in an integrated, intelligent way. And by mapping this, we're learning what normal patterns look like, so we can start spotting when things go wrong," Mani said. Organ systems are known to work together to help one adapt and function under conditions that produce stress in the body. The study looked at 22 healthy volunteers who were monitored using wearable sensors during exposure to three stressed environments -- low oxygen (hypoxia), sleep deprivation and physical moderate intensity exercise (cycling). A face mask measured the participants' breathing gases, while a pulse oximeter tracked blood oxygen levels.

New Delhi: In a feat that goes far beyond adventure tourism, Divya Singh, a young woman from Uttar Pradesh, has completed a journey most seasoned explorers would hesitate to attempt. Starting from Kathmandu, she cycled all the way to Everest Base Camp, battling extreme weather, high-altitude conditions, and unforgiving terrain. Her achievement has quickly gone viral, inspiring thousands online. What makes this expedition remarkable is not just the destination, but the sheer effort behind it. Over 14 consecutive days, Divya cycled for 10 to 12 hours daily, navigating steep climbs, rocky trails ...Read More >
In a clear case of medical negligence, a 34-year-old woman died after doctors transferred the wrong blood type at Kakinada Government General Hospital, Andhra Pradesh. On Tuesday, November 26, the deceased, Bhavana Sirisha, was given AB+ blood group instead of O+. A house surgeon mistakenly transferred the wrong blood type. Sirisha, a resident of Palakollu in West Godavari district, was suffering from kidney ailments for the last four years and was admitted to the hospital for treatment. Doctors had advised a blood transfusion with 'O positive' group blood due to low hemoglobin levels. The ...Read More >
Lifestyle factors such as drinking and smoking could contribute to increased severity of obstructive sleep apnoea Letting your hair down at the weekend might be a well-known recipe for a hangover, but researchers say it might also increase the severity of a common sleep disorder. Obstructive sleep apnoea (OSA) involves complete pauses in breathing or partial reductions in airflow that arise because muscles in the back of the throat relax, causing the airways to narrow or close. It is more commo ...Read More >
India coronavirus update: India is witnessing a significant resurgence of Covid-19, with active cases rising 58-fold over the past 20 days, according to data from the Union Health Ministry. On May 16, the country reported just 93 active Covid cases, but that number has now jumped to 5,364. The virus has resurfaced across 29 states and union territories, raising concern among health authorities and prompting renewed preventive measures. In the last 24 hours alone, over 500 new infections were reported. Kerala leads the count with 1,679 active cases, followed by Gujarat (615), West Bengal (596) ...Read More >

Gorakhpur: Divya Singh (28), a teacher from Gorakhpur, Uttar Pradesh, has become the first Indian woman and the second woman globally to reach Mount Everest Base Camp (EBC) on a bicycle, NDTV reported. She began her journey from Kathmandu and reached the base camp at an altitude of 17,560 feet after a 14-day expedition. During the journey, Divya faced extreme conditions, including temperatures dropping to -12°C, low oxygen levels, and strong winds. She cycled for 10 to 12 hours daily across steep and rugged mountain terrain. In stretches where cycling was not possible, she carried her bicycl ...Read More >

Walking for just 30 minutes a day can have powerful benefits for both your body and mind. This low-impact exercise boosts heart health by improving circulation and reducing the risk of cardiovascular diseases. Regular walking aids in weight management by burning calories and promoting gradual weight loss. It also enhances energy levels, reduces fatigue, and supports mental health by releasing feel-good endorphins, lowering stress and anxiety. Additionally, walking improves joint health by reducing stiffness and preventing injuries, particularly in the lower back, hips, and knees. Incorporating ...Read More >
