Why Does Too Much Sleep Make You Tired?

Disruption of Circadian Rhythm

The body is governed by the internal clock, known as the circadian rhythm, that controls wakefulness and sleepiness. The cycle is disrupted when you sleep, which can lead to:

• Sleep inertia – Waking up during deep sleep phases causes grogginess.
• Delayed melatonin release – The brain can be confused, and you feel exhausted at random moments.
• Reduced serotonin levels – It affects energy and mood.

• Low blood sugar – The inability to eat due to prolonged sleep can lower the energy levels.
