What this lesson covers

• Why sleep position is a direct input to TOS symptoms — and which positions to avoid
• Pillow setup for back sleepers and side sleepers
• Workstation setup — monitor height, keyboard position, arm support
• Phone and screen habits — the one change with the fastest return

The principle

You exercise for 15 minutes a day. You sleep for 7 to 8 hours and sit at a desk for another 7 to 8. The load your body carries during those other 23 hours either supports your recovery or undermines it.

This lesson is about closing that gap. Not perfecting your environment overnight — but making one or two targeted changes that reduce the sustained load on the outlet around the clock.

Sleep positions — quick reference

• Best: On your back, arms at your sides, neck in neutral.
• Acceptable: On the unaffected side, bottom arm in front (not under the pillow), top shoulder not collapsing forward.
• Avoid: On the affected side, arm overhead, or face down (prone).

Workstation — quick reference

• Monitor: At or just below eye level. Looking down = head forward = increased cervical load all day.
• Keyboard and mouse: Close enough that elbows stay near your sides. Reaching forward sustains pec minor and scalene stretch.
• Chair height: Elbows at roughly desk height. Armrest or forearm pad recommended if you use a mouse heavily.

This week

Pick one change from this lesson and implement it before your Phase 2 check-in. Sleep setup, monitor height, or phone position. One change, consistently. That's the ask.

The PDF guide is in the resources section below — all recommendations in a printable format you can share with a partner or post at your desk.

Lesson 6 — Phase 2 check-in. Before you do it, give yourself at least one to two full week(s) of consistent work across all four previous lessons. Then re-rate your symptoms and meet me there.
