Sleep is a fundamental part of our lives. It's a time for our bodies and minds to rest, rejuvenate, and prepare for the next day. But not all sleep is created equal. There's light sleep, deep sleep, and REM sleep. Each stage has its unique benefits and functions. But one type of sleep stands out as particularly crucial: core sleep. Core sleep encompasses deep sleep and REM sleep. It's during these stages that our bodies undergo essential physical restoration and our minds process and consolidate memories. But how much core sleep do we actually need? This question is more complex than it might seem. The answer can depend on a variety of factors, including age, lifestyle, and overall health. In this article, we'll delve into the science of core sleep. We'll explore its importance, how much is ideal, and how to optimize it for better health and cognitive function. Whether you're a health coach, a science journalist, or a biohacker, this comprehensive guide will provide you with the insights you need to understand and improve your core sleep.

Aging brings a variety of physiological changes, many of which affect cognitive function. While some memory changes are normal, others may indicate a more concerning decline in brain function. Understanding what is normal age-related memory loss versus early signs of cognitive impairment is crucial for adopting strategies that promote long-term brain health. Many individuals wonder, "what year do you forget memories?" or "at what age does memory loss start?" While there is no definitive year when memory decline begins, research indicates that mild changes can emerge as early as the late 20s, with more noticeable shifts occurring in one’s 40s and beyond. However, these changes do not necessarily indicate permanent cognitive decline, and adopting proactive strategies can help mitigate memory loss.
