The claimWhat Stephen actually said
In a March 2025 interview about how he spends his recovery time, Curry described sleep as the piece of the routine that matters most in his sixteenth NBA season. He talked about amount, consistency, and habits rather than any single gadget, and separately described compression boots and an audio sleep track as add-ons. He also called himself a night owl who gets to bed between 11 p.m. and 1 a.m.

- Mah CD, Sleep, 2011, sleep extension in collegiate basketball players improved shooting accuracy by about 9 percent and sprint times.
- Cunha LA, Sports Medicine Open, 2023, systematic review of 25 studies found increasing sleep duration or napping was the most effective intervention for athletic performance.
- Cappuccio FP, Sleep, 2010, meta-analysis of 16 prospective studies and 1.38 million participants found short sleep associated with 12 percent higher all-cause mortality.
Why it mattersWhy this matters for longevity
Sleep is one of the few recovery inputs that has been tested in randomized and controlled designs rather than only observed
Short sleep is linked to higher all-cause mortality across very large cohorts, so this is not only an athletic-performance question
The specific thing Curry names, consistency, is increasingly studied as a separate factor from total hours
The evidenceWhat the science says
In a controlled study of collegiate basketball players who extended sleep toward 10 hours a night for five to seven weeks, free throw accuracy improved about 9 percent, three-point accuracy about 9.2 percent, and sprint times and reaction time improved as well. A 2023 systematic review of 25 sleep-intervention studies in athletes concluded that increasing night sleep or adding naps was the most effective intervention for physical and cognitive performance, while sleep hygiene advice alone showed no significant effect. Pooled cohort data covering 1.38 million people found roughly a 12 percent higher risk of death with short sleep.
What the evidence does not support is the idea that piling on sleep hours reverses aging or extends life. The mortality data are observational, and long sleep is associated with higher risk too, which is more likely a marker of underlying illness than a cause. The athlete trials are small, short, and run in young people, so the size of the benefit for a general adult is unknown. Sleep tracks, compression boots, and brainwave audio devices are not what the trials tested.

The practical lesson
Protect a consistent sleep window before spending money on any recovery device.

SupplementsThe supplement angle: Magnesium and vitamin D
Support a habit, do not replace one
Neither is a sleep aid in the way marketing suggests, and evidence for magnesium improving sleep in people who are not deficient is thin. Anyone considering a supplement for sleep problems is better served by ruling out an underlying sleep disorder first.
Supplements can support good habits. They do not replace sleep, movement, nutrition, or medical care. Talk with your healthcare provider before starting anything new.
