One commonly mentioned supplement to help with sleep is melatonin. However, its effectiveness is considered modest at best. It is generally not recommended as a first-line treatment for insomnia. Instead, focus on non-pharmacological measures to improve sleep hygiene and quality. Some tips include turning off screens at least an hour before bed, establishing a consistent wake-up time, keeping the bedroom for sleep and intimacy only, avoiding looking at the clock during the night, avoiding naps during the day, limiting caffeine intake, and trying cognitive-behavioral therapy with a therapist if needed. These strategies may take time to implement, so be patient and seek medical advice if needed.
