Sleep is Critical for Muscle Growth
How does sleep affect muscle growth?
Sleep is one of the foundations of recovery and muscle growth. Sleep deprivation can reduce muscle protein synthesis, worsen hormonal balance, and make training performance feel harder than it should. A great program looks much worse when recovery is poor.
Key Takeaway
Poor sleep reduces muscle protein synthesis.
Actionable Tip
Aim for 7–9 hours of quality sleep before looking for fancy recovery hacks.
