Heart Specialist from California Raises Concerns Over Melatonin Use

A renowned cardiologist based in California has issued a warning regarding the hidden dangers linked to long-term melatonin use. Dr. Sanjay Bhojraj, who has two decades of experience in heart health, stated that consuming melatonin nightly for over one year could potentially increase the risk of heart failure by 90% over a five-year span.

Melatonin, a hormone naturally produced by the brain, plays a pivotal role in regulating the sleep-wake cycle and signaling the body when it's time for rest. Many individuals resort to melatonin supplements to tackle sleep difficulties. However, Dr. Bhojraj emphasizes that most users likely do not require the supplement and would benefit more from improved sleep habits.

In a video shared on Instagram on November 14, Dr. Bhojraj referenced a study by the American Heart Association, which involved over 130,000 adults. This research revealed that individuals who utilized melatonin for longer than a year had a significantly elevated risk of experiencing heart failure down the line.

He pointed out that while melatonin is considered natural, that doesn't imply it is devoid of risks. Other natural hormones, such as cortisol, estrogen, and insulin, can also adversely affect the body when not balanced correctly. Melatonin's impact is similar; excessive consumption over time can muddle the body’s internal clock.

Moreover, Dr. Bhojraj cautioned that nightly melatonin use could disrupt the circadian rhythm, which governs sleep and various bodily functions. It might alter hormone signaling and diminish the body’s capacity to produce melatonin on its own. Most individuals, he added, do not suffer from an actual melatonin deficiency; rather, they exhibit issues with their sleep patterns, including excessive screen time at night, irregular sleeping hours, and inconsistent bedtime habits.

He urged the public to prioritize straightforward solutions to enhance sleep, such as maintaining a consistent bedtime, dimming lights in the evening, and refraining from phone usage late at night. Dr. Bhojraj argued that these minor adjustments could lead to natural improvements in sleep without jeopardizing heart health.

His concluding message is clear: although melatonin may appear harmless, its long-term use carries potential risks to heart health and disrupts the body’s inherent balance.
