Sleep, stress and the quiet collapse of your sex drive
Five hour nights and constant cortisol do more damage to libido than most men realise. The fix is unglamorous and it works.

The cortisol testosterone seesaw
Chronic stress keeps cortisol elevated, which suppresses the signalling that drives testosterone production and dampens desire directly through the brain.
What one week of short sleep does
Studies of healthy young men restricted to five hours a night show meaningful drops in daytime testosterone within a week, along with reduced mood and energy.
Sleep apnoea, the missed diagnosis
Snoring, waking unrefreshed and morning headaches are worth investigating. Treating apnoea often improves erections and libido without any other intervention.
A four week reset
Fixed wake time seven days a week. No alcohol within three hours of bed. Screens out of the bedroom. Twenty minutes of daylight in the morning. Two resistance sessions a week.
What to expect
Energy improves first, usually in ten days. Libido and morning erections follow over three to four weeks. If nothing shifts, get bloods done.

Habits help. A plan helps more.
