As per what the experts suggest, 1-5mg of melatonin every day is safe for adults and the elderly can stretch it to 6mg but not more than that. It is also important to consider that the effect of melatonin lasts a good 20-50 minutes; this increases the chances of developing addiction if you take it every day.
Five mg of melatonin may last for four to eight hours. How long 5 mg of melatonin lasts exactly will depend on the type of supplement you take, your age, and whether you smoke, consume caffeine, or take medication. The larger the dose of melatonin you take the longer it'll likely last in your system.

In particular, melatonin has been shown to influence BP and heart rate (11–14). Ingestion of melatonin has been demonstrated to reduce systolic, diastolic, and mean BPs; resting plasma noradrenaline during standing; and pulsatility indices, a measure of vascular resistance, in healthy adults (11–13, 15).
What cancels naturally occurring melatonin sleep hormone? Because melatonin is triggered by darkness, being exposed to light at night can block melatonin production, especially the blue light from digital devices such as cell phones.
