How exercise changes sleep without being a sleeping pill

Exercise shifts temperature and sleep drive without sedating the brain the way a pill does.

From the opening

Exercise changes sleep by adding metabolic load, moving body temperature, and repeating a bout of activity at a given hour. It is not a sleeping pill, because it does not act on the receptors that sedative drugs act on. The opening covers the cool-down matters more than the burn, late hard effort can delay sleep, and pressure and temperature, not a sedative.

The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.

Inside

The cool-down matters more than the burn
Late hard effort can delay sleep
Pressure and temperature, not a sedative
A repeated hour is a weak cue
Where the idea stops applying
A distinction worth keeping
