Lifestyle & wellbeing

The habits people are told to fix, separated into the ones with fertility evidence and the ones with general-health evidence.

Daily habits

How much caffeine is okay? Does sleep affect fertility?

Stress and the body

How do I calm my body while I'm trying? Caffeine limits, stress, sleep and inflammation — what moves the needle and what doesn't. Do stress-reduction programmes help?

Complementary approaches

Your environment

Do everyday chemicals and plastics affect fertility? Phthalates, BPA and pesticide residue — what the cohorts found, and the five habits worth changing.
