Your sleep problems may be caused both by lifestyle (e.g. eating habits, circadian rhythm entrainment, light exposure, and weight gain) and genetics. If you struggle with significant sleep issues, it is important to understand how your genetics may play a role so that you can use this information to your advantage.
Sometimes what appear like insomnia, low quality sleep, or other forms of sleep problems might just be because you live incompatibly with your genetic makeup. As a result, you might never wake up feeling rested, your stress response may be constantly overactivated, or you might really struggle to lose weight for no apparent reasons. Your genetic makeup plays a large role in determining the best chronobiology and lifestyle for you. Read this post to learn more about this.
