Is it OK to turn off my iPad every night?

I'm curious, is it advisable to power down my iPad every evening? I've heard conflicting opinions on whether this practice is beneficial for the device's longevity and battery health. On one hand, some argue that shutting down the device regularly can help preserve battery life and prevent overheating. On the other hand, others claim that leaving it in sleep mode is more efficient, as it allows for faster startup times and maintains the device's readiness for immediate use. What's your take on this matter?
