Very interesting 🧐 information about one of the benefits of using creatine in exercise recovery for Women. According to this study by Aguilar Bonfim Cruz et al., Nutritionists, 2024, women taking Creatine slept 48minutes longer on training nights compared to those who didn’t.
Sleep problems are all too common — but they don’t affect everyone equally.
Roughly one in five adults struggles to fall or stay asleep most nights, and women are about 60% more likely than men to experience these difficulties.
Most explanations point to stress or lifestyle. But there may be another factor hiding in plain sight: cellular energy.
In a national analysis of nearly 6,000 adults, people who consumed at least 1 gram of creatine per day were 30% less likely to report trouble sleeping than those who ate less.
That idea recently got its first direct test.
Researchers from the University of Idaho ran a double-blind, placebo-controlled trial in 21 women, each taking either 5 g/day of creatine monohydrate or a maltodextrin placebo for six weeks.
Participants trained twice a week with supervised resistance sessions, while their sleep was tracked nightly with Oura Rings. The researchers also controlled for menstrual cycle phase to ensure natural hormonal fluctuations were accounted for.
Women taking creatine slept about 48 minutes longer on training nights than those on placebo, averaging about 7½ hours on training nights, compared to just 6½ hours in the placebo group.
Why? During hard training, your cells burn through ATP faster than it can be rebuilt. Once phosphocreatine (PCr) reserves get depleted, energy sensors such as AMP-activated protein kinase (AMPK) flip on, flagging an energy crisis. This in turn keeps the sympathetic nervous system firing — in effect, the biological signature of being “tired but wired.”
Creatine changes that timeline.
