Rhythms of biology
In this video, we will talk about the rhythms of biology, specifically the circadian rhythm and the biological clock. This is a natural, internal process that regulates the sleep-wake cycle and repeats itself approximately every 24 hours. This rhythm is crucial for health as it influences various physiological processes.
The circadian rhythm plays a key role in regulating sleep-wake cycles. Melatonin, a hormone released by the pineal gland, is a key regulator of sleep and is released in the dark, signalling to the body that it is time to sleep. Research shows that disruptions in circadian rhythms, such as shift work or exposure to blue light at night, can lead to sleep disturbances, insomnia and other sleep problems.
In addition, circadian rhythms have an important influence on cardiovascular health. Circadian rhythm disturbances are associated with a higher risk of hypertension, heart attack, stroke and other chronic diseases. It also affects metabolism and weight management. Studies show that circadian rhythm disturbances can contribute to the development of metabolic disorders such as obesity, type 2 diabetes and metabolic syndrome. For example, irregular meals and irregular sleep patterns can disrupt metabolic processes, leading to weight gain and insulin resistance.
Intermittent fasting and time-restricted eating, based on the body's natural circadian rhythms, have many health benefits. They affect metabolic health, reduce the risk of cardiovascular disease, improve blood glucose regulation, reduce fatigue and anxiety, reduce the risk of cancer, affect mitochondrial health and much more. In this lecture, we will take a closer look at the cell biology of time-restricted feeding and some suggestions on how you can incorporate it into your life.
