Do you wake up feeling groggy and unrested, even after getting a full night's sleep? Sleep isn't just about quantity—it's about quality and consistency. Your sleep cycle plays a critical role in determining how refreshed you feel each morning.
In this guide, we'll explore the science behind why you might feel unrested, the key factors that disrupt sleep cycles, and effective ways to fix your sleep for better energy and focus.
Sleep occurs in cycles that repeat every 90-110 minutes, consisting of four stages:
Disruptions in these cycles can leave you feeling fatigued and foggy, even if you sleep for 7-9 hours.
If your alarm wakes you in the middle of deep sleep, you may experience sleep inertia, a state of grogginess and mental sluggishness.
Factors like noise, light pollution, and temperature fluctuations can cause micro-awakenings that prevent you from getting restful sleep.
Your circadian rhythm is your internal clock that regulates sleep. Irregular bedtimes, night shift work, or excessive screen time can throw it off balance.
Sleep disorders like sleep apnea or restless legs syndrome can disrupt your sleep cycles, leaving you unrested.
Chronic stress and anxiety can keep your nervous system in a hyperactive state, making it difficult to reach deep sleep stages.
