What is the safest sleep aid to take every night?

I'm curious to know, when it comes to sleep aids, what is the safest option to take every night? With so many products on the market, it can be overwhelming to decipher which ones are effective and SAFE for long-term use. Is there a particular ingredient or type of sleep aid that stands out as the most reliable and harmless? I'm interested in understanding the potential risks and benefits associated with different sleep aids, as well as any natural alternatives that might be worth considering.
