Discover the Transformative Power of Sleep for Your Brain and Body: 

Welcome to part two of our Healthy Brain & Body blog series, where we delve into the profound effects that sleep has on our mental health. In this installment, we’ll explore the remarkable benefits of sleep and how it impacts our overall well-being.

Scientific research has unequivocally shown that sleep plays a crucial role in various aspects of our cognitive function. Not only does it enhance memory recall, but it also regulates metabolism and reduces mental fatigue. When we sleep, our brain undergoes a process of reorganization and recharging, while eliminating toxic waste byproducts that accumulate throughout the day. This evidence demonstrates the vital role of sleep in maintaining the normal functioning of our brain (1).

During deep sleep and the REM phase, our body allocates its resources to repair tissues and cells, as well as rejuvenate the energy and function of the central nervous system. This process is essential for recovering from physical and mental stress (1).

Understanding the Key to Healthy Sleep Hygiene

Understanding the significance of healthy sleep hygiene is paramount. One crucial factor to consider is the timing of our meals before bedtime. Autophagy, the process by which our body eliminates waste in the brain and body, only occurs during fasting. Consuming food close to bedtime inhibits autophagy, allowing bad cells and stress hormones to accumulate, leading to toxic build-up and impaired recovery (2).

The First 90 Minutes: A Make-or-Break Phase

The first 90 minutes of sleep are particularly crucial for the cleansing and rejuvenation of our cells. For optimal, restorative sleep, it is important to avoid having insulin in our bloodstream when we go to bed. Ideally, we should refrain from eating 3-4 hours before bedtime, allowing our body ample time to clear insulin. Going to bed hungry leads to waking up energized and refreshed, while going to bed full results in feeling hungry and tired upon waking (2). This is especially important for women since their circadian rhythm is one hour shorter than men’s.

These insights are especially valuable for those practicing intermittent fasting. While many individuals choose to eat later in the day, this disrupts a healthy circadian rhythm. To optimize sleep and overall well-being, it is advisable to break the fast earlier in the day and abstain from eating later in the evening.

Simple Changes, Big Impact

Incorporating simple changes to our habits and routines can have a profound impact on our brain, mental health, and body. By prioritizing restorative sleep, we enhance our ability to retain new information, improve cognitive function, regulate emotions, and recover from stress.
