The Impact Of Diet On Sleep Quality
Sleep is a fundamental aspect of human health, influencing everything from mood and cognitive function to physical well-being. While many factors affect sleep quality, one of the most significant yet often overlooked is the diet on sleep quality. What we eat not only impacts our physical health but also plays a crucial role in how well we sleep. This blog delves into the various ways the diet on sleep quality affects our rest, offering insights and practical tips for improving sleep through dietary choices.
1. Understanding Sleep Quality
Before diving into the dietary aspects, it’s important to define what sleep quality means. Sleep quality refers to how well you sleep, encompassing factors such as the time it takes to fall asleep, how often you wake up during the night, and how rested you feel upon waking. High-quality sleep is typically characterized by:
- Adequate sleep duration: Most adults need 7-9 hours per night.
