Welcome to the Physiology Friday newsletter. Physiologically Speaking is a reader-supported publication. When we don’t get enough sleep, our physiology suffers—insulin sensitivity tanks, cognitive function wanes, and physical performance is drastically impaired. One potent strategy is exercise. a total of 3.5
Welcome to the Physiology Friday newsletter. Physiologically Speaking is a reader-supported publication. Exercise prevents and reverses cardiovascular disease, but whether high-intensity exercise training (HIIT) is safe and effective for adults after minimally invasive heart surgery is unknown.
This can then become a vicious cycle – if we feel anxious, frightened, or stressed in response to an ectopic beat this can lead to physiological symptoms associated with the stress response including changes to our heart rate. For example, avoiding cardiovascular exercise or activities triggering breathlessness.
So cardiomyopathies, valve problems, myocarditis and previous heartattacks all cause a problem with the pumping function of the heart. It is also unique because it works using the Doppler effect, you can get not only an anatomical evaluation of the heart but also physiological assessment.
The convenience of processed foods, high intake of saturated fats, and inadequate exercise collectively contribute to an increased risk of heart-related problems. Chronic stress triggers physiological responses that can adversely affect the cardiovascular system.
The evidence that high levels of exercise and subsequent fitness are linked with increased lifespan and health span is clear. By the end of this article, you should be convinced that high levels of fitness and daily exercise are a MUST for a longer quality of life without major illness. Here’s why. Enjoy the process.
” While an awe-inspiring anecdote, our knowledge of human limits, physiology, and the sheer number of participants in endurance sports is enough evidence to conclude that running a marathon won’t kill you. Physiologically Speaking is a reader-supported publication. ” Isn’t exercise good for us?
Poor sleep generally impacts cognitive well-being, nutrition and exercise routines, all of which are key pillars of cardiovascular health. It significantly increases the risk of heartattack, stroke and atrial fibrillation. Takeaway Obstructive sleep apnea is common. It frequently goes undiagnosed. It is potentially avoidable.
In a cohort of >3,000 people from the National Health and Nutrition Examination Survey (NHANES), sleeping <6 hours each night predicted a higher prevalence of stroke, heartattack, and chronic heart failure. 19 20 Mortality from CVD and coronary heart disease is also increased in women with short sleep, but not men.
Welcome to the Physiology Friday newsletter. Physiologically Speaking is a reader-supported publication. These mechanisms collectively heighten the likelihood of major adverse cardiovascular events such as heartattacks and strokes—even if you’re someone who regularly exercises!
This has raised concerns that long-term, high-volume exercise might be detrimental to heart health. Notably, athletes engaging in very vigorous-intensity exercise are more likely to develop calcified plaques. Physiologically Speaking is a reader-supported publication.
