You naturally transition between light and deep sleep throughout the night. The early morning hours are dominated by lighter sleep (REM sleep).

    Any slight disturbance—a noise, a change in temperature, or a full bladder—is enough to wake you during this light sleep phase.

  1. Lifestyle Habits

Your daily choices have a direct impact on your sleep quality.

    Caffeine/Alcohol: A late-afternoon coffee or a « nightcap » can disrupt your sleep cycle later in the night.
    Late-Night Meals or Screens: Eating too close to bed taxes your digestion, while the blue light from phones and TVs suppresses melatonin, your sleep hormone.*
