Melatonin - Diverse Benefits
The pineal hormone melatonin also has several other benefits to its credit. A few are listed here:
- As an antioxidant, melatonin is quite potent against age-related deterioration of the brain. The effect of toxic free-radicals on the brain can be averted with melatonin supplements.
- Melatonin has also proved its mettle in reversing the effects of ageing, according to studies on mice. This is attributed to melatonin’s ability to suppress stress through the opoid system and also to its ability to boost the immune system
Nonetheless, some anti-ageing claims seem dubious.
- Scientists have noted a marked decrease in melatonin production as one ages. Progressing age also results in higher incidence of debilitating bone conditions, like osteoporosis. Research is attempting to establish a cause-effect relation between these two facts. For now, however, we know that melatonin does stimulate osteoblasts, that make up the bone tissue.
- Certain studies have also linked this pineal hormone with better functioning of the immune system.
- Melatonin also affects a person’s ability to memorize and learn things quickly
- Schizophrenics are often fazed by tardive dyskinesia which is characterized by involuntary and repetitive movements. Caused by the drugs used to treat gastrointestinal neuro and psychological conditions about half of all hospitalized schizophrenics have to deal with this condition. The antioxidant effects of melatonin have proved to be particularly effective in reversing this condition. Also, the hormone can be used as a short-term hypnotic for schizophrenic patients dealing with insomnia,in place of high-dosage sedatives. Melatonin results in improved sleep quality and lesser nighttime awakenings.
Advertisement- Scientists are still unclear as to the effects of melatonin on hypertension and heart disease. Animal studies have pointed to the hormone as protection for the heart from the ill effects of ischemia (reduced blood flow to the heart causing an attack). Some claims have also been made regarding melatonin bringing about a slight reduction in blood pressure. These claims, nevertheless, need to be substantiated with more and better-designed research.
- Post-menopausal women can regulate and promote sleep with melatonin supplements; however, it must be taken only in small doses and in the short-term alone.
- In the future, melatonin may also prove to be an essential component of the treatment for migraine and cluster (or, suicide) headaches.
- Below par levels of melatonin have been observed in patients with depression, Seasonal Affective Disorder (caused by lesser daylight exposure in winter months), panic disorder and anxiety. Light therapy and supplemental melatonin may prove conducive to treatment; although certain researchers advise against the use of melatonin to alleviate signs of depression.
