    Did this ever happen to you? As you get out of bed or get up from a chair, you suddenly feel faint or dizzy. When you get up, your head may spin since your blood pressure immediately falls. You can experience tunnel vision, your eyesight might be blurry or faint. You might also feel confused and lightheaded, which would only make this already terrifying experience worse. Less frequently, you can experience a dull ache on the backs of your shoulders and neck. Rarely, you might faint or lose consciousness. These are signs of orthostatic hypotension, a disorder that develops when blood pressure decreases significantly as a result of a  shift in position.   What is Orthostatic Hypotension An excessive drop in blood pressure (BP) when in an upright position is known as orthostatic (postural) hypotension. A decline of more than 20 mm Hg systolic, more than 10 mm Hg diastolic, or both meet the mainstream definition. Within a few seconds to a few minutes of standing, fai...

    Craving a substantial meal or an endless supply of your preferred snack is one thing. It's another thing to be so hungry that you snap at the slightest inconvenience. This distinguishes between hunger and "hangry," a clever mashup of "hungry" and "angry." Whether you've personally gone through it or not, you probably know someone who has. But is it a physiological phenomenon, or is it simply a more sophisticated form of weeping for your bottle? The biological basis of hanger According to gastroenterologist Christine Lee, MD, "There is a physiological explanation why some people get angry when they're hungry." She says, "The level of sugar (glucose) in your blood falls after you haven't eaten for a while. When your blood sugar levels go too low, a series of hormones are released, including the stress hormone cortisol and the adrenaline (the fight-or-flight hormone). To increase and stabilize your blood sugar, these hormone...

    The World Health Organization (WHO) claims that depression is a widespread condition throughout the world. 264 million people around the world are affected by it, and whether it's moderate or severe, it can become a serious health issue. Although both psychotherapy and medicine are useful for treating depression, exercise is a free and widely accessible alternative. According to integrative medicine specialist Irina Todorov, MD, exercise can not only help with depression but also lower blood pressure, enhance cholesterol profile, help control blood sugar, and cut the risk for heart disease, diabetes, and common malignancies. Of course, maintaining or achieving a healthy weight is possible with exercise. How exercising can improve your mood Food preferences, stress levels, and physical exercise all have a significant impact on mood and can lower your chances of developing anxiety and depression. Here are five reasons why exercising can improve your mood.   1. If you ex...

  Your heartbeat is controlled by a network of nodes, cells, and signals called the cardiac conduction system. Each time your heart beats, electrical signals go through your heart. These impulses induce various cardiac regions to enlarge and constrict. The heart's expansion and contraction regulate the body's blood flow. What is the heart's conduction system? The network of specialized cells, electrical signals, and nodes (groups of cells that can either be nerve or muscle tissue) in the heart's conduction system is what keeps your heart pumping. Your heartbeat is controlled by two varieties of cells: a.) The electric signals are carried via conducting cells. b.) Your heart's contractions are managed by muscle cells. The cardiac conduction system in your heart gives the signal to begin a heartbeat. Additionally, it transmits messages that instruct various heart muscle groups to rest and contract (squeeze). Your heart's ability to contract and relax regulates ho...
