Light therapy promising for treating major depression
 

light therapy and melatonin
 

I find studies about light therapy draw my attention every time as I am so sensitive to needing light for my emotional well being.
This particular article mentions the increased melatonin production and the resultant decrease in cortisol levels."The light-therapy group also showed an increased level in the evening of the sleep-promoting hormone, melatonin, and a decrease in levels of cortisol, the stress hormone."
That research fits nicely with the articles sited in the new thread by imark3000 about the ratio of dopamine to acetylcholine. One of those articles states
"Melatonin also can decrease cortisol levels (adrenaline), which can be high from chronic stress. Decreasing excess cortisol levels can be helpful in decreasing the amount of dopamine depleted to make adrenaline hormones."
Logically, Vitamin D and all the recent hub-bub and research on it, must also be similarly involved.
Out into the sunshine I will be going! And I am going to try to be more faithful in taking 3 mg. of melatonin before bed.:Zzzz:

Sorry, I've been out of the loop for a month and just starting to review the older postings but this post also is related

Regarding MELATONIN -- My physician warned me to NEVER take it; it's been shown to cause heart problems.

Wow! My neurologist recommended it for insomnia! How do I decide?

"Based on available studies and clinical use, melatonin is generally regarded as safe in recommended doses (5 milligrams daily) for up to two years.Available trials report that overall adverse effects are not significantly more common with melatonin than placebo. However, case reports raise concerns about risks of blood clotting abnormalities (particularly in patients taking warfarin), increased risk of seizure, and disorientation with overdose. "

You should read the rest so that you know about the rare stuff. http://www.mayoclinic.com/health/mel...SECTION=safety

Thank you! You are an amazing resource....sounds like something to be used with caution - especially as I have some issues with blood clotting and cholesterol.
