The Interconnection between Circadian Rhythms and Ageing
This section will explore the interconnection between circadian rhythms and ageing. Circadian rhythms are natural, internal processes that regulate our sleep-wake cycle, hormone production, metabolism, and other bodily functions. Our biological clock controls these rhythms, which are influenced by external cues such as light and darkness.
How Disrupted Sleep Patterns Affect Ageing
Disrupted sleep patterns, such as insomnia or irregular sleep schedules, can significantly affect ageing. Sleep is essential for our overall health and well-being, allowing our body to rest, rejuvenate, and repair itself. When we experience sleep disturbances, it can disrupt our circadian rhythms and negatively impact various aspects of our health.
Ageing can lead to changes in sleep patterns, with older adults often experiencing difficulty falling, staying, or waking up too early. Sleep disruptions can contribute to cognitive decline, memory problems, mood disorders, and increased risk of chronic conditions like cardiovascular disease, diabetes, and obesity.
Research has found that disrupted sleep patterns may accelerate the ageing process at the cellular level. It can increase oxidative stress, inflammation, and impaired cellular repair mechanisms. These factors can contribute to DNA damage, telomere shortening, and accelerated cellular ageing.
Additionally, disrupted sleep can affect growth hormone production, which plays a crucial role in tissue repair and regeneration. This can further impact our ability to recover from daily wear and tear, leading to faster physical and cognitive decline.
