Yes, melatonin can affect blood pressure, generally causing a modest decrease, especially at night, but effects vary, with some studies showing reductions in hypertension patients and others reporting no significant change in normotensive individuals, while caution is advised as it might lower BP too much in those on medication or potentially raise it with certain blood pressure drugs.
Single melatonin intake can lower BP, but only when melatonin is taken during the day, when general SCN neuronal activity is high and endogenous melatonin levels are low. This effect could be mediated via an immediate inhibition of SCN–neuronal activity inducing a state resembling nocturnal SCN output.

The 60-second trick to lower blood pressure involves deep, controlled breathing, often called "square breathing," where you inhale for 4-5 seconds, hold for 4-5, and exhale for 4-5, repeating to calm your nervous system and slow heart rate, alongside other quick tactics like sipping water, splashing your face with cold water (mammalian dive reflex), or gentle movement. While these provide quick relief, remember consistent lifestyle changes are key for long-term management, and severe spikes need medical attention.
At the beginning, measure your blood pressure at least twice daily. Take it first in the morning before eating or taking any medicine. Take it again in the evening. Each time you measure, take two or three readings to make sure your results are the same.
