The clocks change by just one hour, but from perimenopause onwards it can throw your sleep, energy and mood off for days.

That’s because you don’t have one body clock, you have thousands, set by light, food and movement. When the clocks go back (a whole other debate!), your internal clocks fall out of step.

For 7 mornings, starting Monday 19 October, you’ll receive an email explaining what’s really going on, with simple steps to try that day. You’ll get the inside scoop on how much light your clock really needs (and how to measure it on your phone), why breakfast is the food version of morning light, and how to shift gently so Sunday doesn’t knock you sideways.

No challenge, nothing complicated. Just the science, made practical.
