Welcome to the Physiology Friday newsletter. Physiologically Speaking is a reader-supported publication. When we are standing up or walking around (ambulating), our muscles contract to maintain posture and blood flow increases to meet the metabolic demands of the muscles.
Welcome to the Physiology Friday newsletter. Physiologically Speaking is a reader-supported publication. What physiological mechanisms make moderate to high levels of activity so favorable, especially in our modern environment? This week, I’m sharing one of my favorite articles I’ve ever written.
Our body’s physiological processes oscillate on a 24-hour cycle known as the circadian rhythm. Circadian rhythms in bloodpressure and heart rate, among other functions, are crucial for cardiovascular health and preventing cardiovascular disease. In general, light exposure increases nighttime bloodpressure and heart rate.
Welcome to the Physiology Friday newsletter. Physiologically Speaking is a reader-supported publication. Resting metabolic rate, overnight heart rate, and overnight systolic and diastolic bloodpressure were unaltered by carbohydrate or sugar restriction. No surprises here. That’s a sweet conclusion.
Welcome to the Physiology Friday newsletter. Physiologically Speaking is a reader-supported publication. Clinically, about 1/3 of adults have metabolic syndrome — a cluster of conditions including abdominal obesity, high bloodpressure, high blood glucose, high triglycerides, and low HDL cholesterol.

Welcome to the Physiology Friday newsletter. Physiologically Speaking is a reader-supported publication. For adults with overweight and obesity, resistance exercise increases lean body mass and reduces body fat percentage and fat mass — improving overall body composition.

Welcome to the Physiology Friday newsletter. Physiologically Speaking is a reader-supported publication. The physiology of shivering Cold exposure with shivering activates several physiological responses that can contribute to better metabolic health. You can find more products I’m affiliated with on my website.
But the rising trends of obesity, diabetes, and cardiovascular disease and the falling trend of activity levels lead me to a dark conclusion: things probably aren’t going to get any better. ACE inhibitors block the angiotensin-converting enzyme to reduce bloodpressure. I’m an exercise scientist by training.
Other studies have also unearthed more intricate connections which suggests that physiological conditions, underpinned by biological and chemical factors, may also play a pivotal role in influencing cardiovascular disease (CVD).
However, prolonged exposure to stress can lead to persistently high levels of these hormones, contributing to increased heart rate, elevated bloodpressure, and inflammation, all of which raise the risk of heart disease. People with anxiety often experience elevated heart rates and increased bloodpressure.
Share For people with OSA during sleep, there are recurrent episodes where the airway collapses and obstructs the passage of air to the lungs, resulting in: Lack of oxygen Significant variations in bloodpressure, heart rate and other physiological metrics. Now imagine someone doing that to you every night.
While factors like high bloodpressure, high cholesterol, obesity, and smoking affect both men and women, certain conditions like diabetes, metabolic syndrome, and mental stress tend to pose a higher risk for women. Unique Challenges In Diagnosis Diagnosing heart disease in women poses unique challenges.
Despite heparin and supportive care, the patients mental status and bloodpressure worsened. Whether it's a PE or a severe asthma attack, the cellular physiology of these cells is acutely the same. She also complained of generalized weakness, lightheadedness, diaphoresis, chest pain, and cough.
Welcome to the Physiology Friday newsletter. Physiologically Speaking is a reader-supported publication. In a new study, evening exercise, but not morning exercise, reduced bloodpressure, lowered sympathetic activity, and improved baroreflex sensitivity in a group of adults with treated hypertension.
Welcome to the Physiology Friday newsletter. Physiologically Speaking is a reader-supported publication. KNG1 and 2 are speculated to play a role in exercise’s effect on improving bloodpressure and insulin sensitivity. All of the major HSPs were upregulated after exercise.
This is due to several factors, including the aging of the population, a rise in obesity, increased detection, and increased survival with AF along with other forms of CVD. Physiologic factors that impact stroke prevention therapy also change over time and can have important implications for proper medication dosing and patient safety.
6 [link] Insufficient sleep has been linked to a greater risk for several health conditions including obesity, diabetes, hypertension, and cognitive decline. The amount of calcium in the blood vessels (known as arterial calcification), a marker of subclinical atherosclerosis, is higher in people with a short sleep duration.
These indirect and direct factors can lead to obesity, hypertension, hyperlipidemia, diabetes, ischemia with no obstructive coronary artery disease (INOCA), CAD, myocardial infarction (MI), and stroke via the hypothalamic-pituitary-adrenal axis, sympathetic-adrenal-medullary system, sympathetic nervous system, and hypoestrogenemia.
