Corregir la postura de cabeza adelante (Text Neck)

Cuando tu cabeza migra hacia adelante de los hombros, cada pulgada añade aproximadamente 10 libras de carga efectiva en tu columna cervical. En la posición típica del trabajador de escritorio, eso es 40–60 libras de carga sostenida.

What is forward head posture?

Forward head posture (FHP), also called "text neck" or "tech neck", is when the head sits in front of the shoulder line instead of directly above it. In a neutral spine, your ear should be vertically over your shoulder when viewed from the side. With FHP, the head is 2–5 cm (or more) in front of that line.

A neutral adult head weighs roughly 5 kg (11 lbs). But the effective load on the cervical spine increases dramatically as the head moves forward: at 2.5 cm (1 inch) forward, the load is roughly 12 lbs; at 7.5 cm (3 inches), roughly 30 lbs; at 10+ cm (4+ inches), 40–60 lbs. This is sustained load — not a brief effort, but continuous compression on your discs and stretch on your posterior neck muscles, for hours every day.

What causes it

The dominant cause at a desk is a screen that's too low. When your monitor is below eye level — as a laptop on a desk almost always is — your head drops and travels forward to look at it. The lower the screen, the further forward the head.

Secondary contributors:

• Phone use (the classic "text neck" position — looking down at a phone held at chest height)
• A chair that encourages a posterior pelvic tilt, which pulls the lumbar flat and then rounds the thoracic spine, which then carries the head forward as a consequence
• Weak deep neck flexors (the muscles that keep the head retracted) and tight suboccipitals and pectorals
• Thoracic kyphosis — a rounded upper back shifts the whole spinal column's center of mass forward

Fix 1: Raise your screen to eye level

This is the highest-leverage single change. Raise your monitor so that the top edge of the screen is at or very slightly below your eye line when sitting with a neutral spine. The screen should be roughly arm's length away (50–70 cm).

For laptops, this almost always requires a stand (books work fine) plus an external keyboard and mouse. A laptop screen at desk level = a laptop screen that's 40–50 cm too low for most people.

Use the monitor distance calculator to find the exact recommended distance and height for your screen size.

Fix 2: The chin tuck exercise

The chin tuck is the most evidence-backed exercise for forward head posture. It directly retrains the deep cervical flexors (longus capitis and longus colli) — the muscles that are elongated and weakened in FHP — and gently stretches the suboccipitals, which are chronically short.

How to do it:

1. Sit or stand with your back against a wall, or just sit upright.
2. Without tilting your head down, gently draw your chin straight back — as if making a double chin. You should feel a gentle stretch at the base of your skull and lengthening at the back of your neck.
3. Hold for 5–10 seconds. Breathe normally.
4. Repeat 10–15 times, 2–3 times per day.

It should feel like a stretch, not pain. If there's sharp pain, stop and consult a physiotherapist.

Fix 3: Thoracic extension

Because forward head posture is often driven by thoracic kyphosis (a hunched upper back), mobilizing the thoracic spine can address the root cause.

Foam roller extension: Place a foam roller horizontally across your upper back at mid-thoracic level (around the shoulder blade level). Support your head with your hands, and gently extend backward over the roller. Hold 30–60 seconds at each level, working up and down the thoracic spine.

Chair back extension: Sit in a firm chair, place your hands behind your head, and lean back over the chair back. Hold 20–30 seconds. Less aggressive than the roller, still effective.

Aim for 1–2 minutes of thoracic mobility work daily — particularly helpful before a long desk session.

Fix 4: Strengthen the lower trapezius and rear deltoids

The lower trapezius depresses and retracts the shoulder blade — the exact movement that's lost in the forward-shoulder pattern that accompanies FHP. It's typically very weak in desk workers.

Band pull-aparts: Hold a resistance band at shoulder height with straight arms. Pull the band apart, drawing your shoulder blades together and down. Control the return. 3 sets of 15–20 reps.

Face pulls (cable or band): Attach a band at face height. Pull toward your face, elbows flared, finishing with hands beside your ears. 3 sets of 15–20. One of the best exercises for upper back health.

Prevention: making the fix stick

The exercises fix the underlying weakness. The setup changes address the input signal. But what actually prevents the drift from happening during a work day is a feedback loop.

Your brain doesn't have a reliable internal alarm for head position — you need an external cue. Options:

• Real-time webcam feedback (unhunch detects head and shoulder position live and alerts you when you drift — the fastest feedback loop)
• Periodic break reminders (use the posture break timer to cue a posture check every 20–30 minutes)
• Postural cues on your environment — a sticky note at the top of your monitor, a phone reminder

The goal is to catch the drift before it compounds into fatigue and structural load. Real-time feedback is the most effective because it intercepts the problem in seconds, not minutes.
