Headaches don't always come from your eyes, stress, or fatigue.
Very often, the real cause is... your neck posture.
When your head leans forward and your neck contracts to hold that position, it creates a set of tensions that trigger the famous “tension headaches.”
Studies clearly show:
“Forward head” posture overloads the cervical muscles and can cause cervicogenic headaches.
These tensions are amplified when you spend a long time in front of a screen, smartphone, or tablet.
Why does this happen?
A bent head greatly increases pressure on the cervical spine.
This tension moves up towards the base of the skull → diffuse or pulsating pain.
Rounded shoulders exacerbate the problem.
Neck muscles fatigue → headaches start.
This mechanism is well-documented in medical and ergonomic literature.
Typical signs
Stiff neck
Pain behind the eyes
Pressure on the temples
Headaches after long screen sessions
Feeling of a “heavy head”
If any of these symptoms appear after poor posture, there is a good chance they are related.
Good news: it can be corrected
Readjusting posture can significantly reduce these types of headaches:
Screen at eye level
Neck aligned with the back
Breaks every 30–45 minutes
Some gentle stretches

And a tool like Ocilys can help you become aware of head tilt and naturally correct alignment. Ocilys does not act like medicine, but it reduces bad postural habits that perpetuate cervical tensions.
