Does yoga help in improving sleep quality?

Hello doctor,

I have been doubling down on my yoga practice over the past year. Well, I have noticed some interesting side effects in the sleep department. No matter how exhausted I am after an intense vinyasa flow or hot yoga class, I seem to toss and turn for hours once I get into bed. Like my body is just buzzin' with energy, and I cannot shut off, ya know? But then I will finally pass out and sleep like an absolute log until morning. It is the weirdest thing. My question is, could this relate to yoga's impacts on posture, breathing, and physical alignment? Maybe it is throwing off my natural sleep cycle in some wacky way at first before allowing higher-quality rest. I have read about yoga Nidra and other practitioners claiming it can enhance your sleep, but I am experiencing the opposite currently. Just wondering if this is a normal adjustment phase or something I should be concerned about. Kindly suggest.
