Rentrée Headaches

"It started the second week back. Now I get a headache by 3pm every Tuesday and Thursday."

By the second week of September, the headache emails start. Same pattern every year: a band of pressure across the forehead by mid-afternoon, sometimes settling at the base of the skull, often radiating up behind the eyes. Painkillers take the edge off but the headache returns the next day, then the day after.

This isn't migraine. In the vast majority of cases, it's a cervicogenic tension headache — pain referred from tight neck and upper-back tissue, triggered by the abrupt return to screen-heavy work after the looser rhythms of August.

Why September Triggers Headaches

Screens, suddenly

Two weeks of holiday means two weeks of less time on screens, more time looking at horizons. The eyes were rested, the convergence muscles relaxed. Day one back is six straight hours of close-focus work, often on a laptop screen tilted slightly off-axis. The visual system fatigues, the suboccipital muscles fire to compensate, and a tension headache follows.

The forward head

Forward head posture isn't a moral failing — it's what happens when you concentrate on a screen 50 cm away. Each centimetre the head drifts forward roughly doubles the load on the deep neck flexors and the upper traps. Sustained for six hours, those tissues refer pain into the skull as a textbook tension headache pattern.

Air conditioning and dry air

Brussels offices crank the AC back up in early September. Cool, dry, recirculated air dehydrates the cervical fascia and dries the eyes — both of which make tension headaches more likely. Add fluorescent overhead lighting after weeks of natural light and the load builds fast.

Stress that returned faster than fitness

The inbox and the calendar fill faster than the body can re-adapt. Jaw clenching during morning meetings, breath-holding while reading dense documents, shoulders creeping toward the ears in the third hour of focus — all standard rentrée patterns and all direct contributors to head and neck pain.

How Osteopathy Helps

Releasing the suboccipital region

The four small muscles at the base of the skull are the primary referrers for tension headache pain. Targeted release here often produces immediate relief — patients regularly describe it as "the pressure dropping out of my forehead" within minutes.

Mobilising the upper cervical and thoracic spine

Forward head posture loads the upper cervical joints (C0–C2) and locks down the upper thoracic (T1–T4). Mobilising both restores the rotation and extension that screen work has been borrowing against, and the headache trigger reduces.

Treating the jaw and upper traps

Headache rarely arrives alone. The jaw, upper traps, and cervical fascia work as one unit. Treating all three together produces faster, more durable change than focusing on the spot that hurts.

Practical changes that stick

You'll leave with a workstation tweak (one or two specific changes, not a redesign), an eye-rest protocol, and a 90-second neck mobility routine to use between meetings. These are the things that prevent the pattern from re-establishing.

Self-Care for the First Month Back

The 20-20-20 rule

• Every 20 minutes of screen work, look at something 20 metres away for 20 seconds. Resets the eye convergence muscles.
• Even better: do it standing at a window once an hour.

Daily 5-minute reset

• Chin tucks × 10 (gentle nod, draw the chin straight back, not down).
• Upper trap stretch, 30 seconds each side.
• Levator scapulae stretch (chin to armpit, 30 seconds each side).
• Doorway pec stretch, 30 seconds.
• Slow nasal breathing, 6 seconds in, 6 seconds out, ten cycles.

Workstation basics

• Laptop on a stand, screen top at eye level. Use an external keyboard and mouse.
• Hydrate. AC offices dehydrate you faster than you think.
• Get outside at lunch. 15 minutes of distance focus and natural light beats every supplement on the market for tension headaches.

When to Book

• Headaches more than two days a week for two weeks
• Painkillers needed most working days
• Neck stiffness alongside the headache
• Jaw clicking or morning jaw soreness has started since the rentrée
• Same pattern as last September — get ahead of it this year
