A recent study using mouse experiments has discovered that the brain-heart link is responsible for triggering fainting episodes. Fainting, also known as Syncope, is usually not a serious concern but can indicate a risk of sudden cardiac death or lead to injuries in some cases. The study found that connections between the brain and heart cause a rapid loss of consciousness followed by a quick recovery. Consulting a physician is advised for individuals experiencing frequent fainting episodes.
Scientists have discovered a neural pathway involving a group of sensory neurons that connect the heart to the brainstem, shedding light on the causes of fainting. By activating these neurons in mice, researchers observed symptoms similar to human syncope, including rapid pupil dilation and reduced heart rate and blood pressure. The study suggests that understanding this neural pathway could lead to new treatment approaches for cardiac causes of syncope. Additionally, researchers found that inhibiting or stimulating a specific region in the hypothalamus affected the duration of fainting episodes and the subsequent recovery.
Bri Clark shared her experience of suddenly fainting and injuring herself in a viral TikTok video, warning others to sit down if they feel like they're going to pass out. Fainting, or syncope, is a common issue seen by emergency medicine doctors and can range from benign to life-threatening. The causes of fainting can include low blood pressure, heart rate changes, anxiety, dehydration, and medication side effects. Clark's injury occurred when she fell face first onto a hardwood floor after having a bad reaction to a delta-8 THC gummy. It took two months for her wound to heal, and she advises others to immediately sit or lie down if they feel like they're going to faint to minimize the risk of injury.
