Oversleeping can lead to headaches due to a disrupted sleep cycle. While sleeping is essential for our health, over sleeping can negatively impact overall health and cause discomfort. Here are a few reasons why we experience headaches after oversleeping. Tap to read!

Dehydration

Oversleeping without hydrating the body can reduce oxygen flow to the brain, leading to dehydration and headache.

Neurotransmitter Changes

While sleeping, our body releases chemicals like serotonin and dopamine. However, when we oversleep, these chemicals get imbalanced, causing headache.

Disrupted Sleep Cycle

The sleep cycle or circadian rhythm gets disrupted when we sleep for longer durations, leading to headaches.

Muscle Strain

When we sleep for too long in the same position, the muscles become stiff and strained. This muscle strain can also lead to headaches.

Low Blood Sugar Levels

When we sleep for long hours without eating, the blood sugar levels drop, causing headaches and fatigue.
