Big idea. Movement, sleep and time outdoors are everyday habits with plausible links to well-being. The best-evidenced of them show moderate average effects in large reviews, but the quality of those reviews matters as much as the numbers.
Outcomes served. O4 (mechanisms and evidence), O5 (read a study critically), O6 (run and log your habit experiment).

Assumed. Modules 1 to 5, in particular effect sizes, odds ratios, direction of cause and your habit protocol.
Where this module fits. Habit week 3 of your capstone experiment runs alongside this module. Weeks 3 and 4 feed your decision rule, so log carefully.
Where this topic appears in practice. Doctors, employers, schools and apps promote exercise, sleep routines and time outdoors. Guideline writers rely on overviews of many reviews to judge how strong the evidence is.
Health note. This module teaches how to read evidence and does not prescribe exercise or sleep routines. Anyone with a health condition, an injury, or doubts about starting more activity should speak to a doctor first. Persistent trouble sleeping or low mood is worth discussing with a qualified professional.
