Frequently asked questions

Sciatic leg pain — normal?

Pressure on the sciatic nerve causes shooting pain. Stretching, side-sleep pillow, prenatal yoga help.

Why are dreams so vivid?

More frequent waking + hormonal shifts make REM dreams memorable. Common and harmless.

Can I dye my hair?

Modern colourants are largely safe in T2/T3 with ventilation. Highlights (off-scalp) preferred.
