How can I sleepless at night?

I've been struggling with insomnia lately and it's really affecting my daily performance. Could you provide some insights on how I can address this issue? Are there any specific strategies or habits I should adopt to improve my sleep quality? I've heard about crypto markets being volatile, so I'm curious if there's a correlation between stress from financial investments and sleep issues. Would it be advisable to reduce my crypto holdings or avoid checking market prices frequently to alleviate some of the stress?
