Re: Can anyone advise a depressed nephew please?

Received this useful info from the friend mentioned above, which hopefully might benefit others as well:

Negative ion Generators:
1. Studies show high levels of negative ions can be as effective at treating Seasonal Affective Disorder (SAD) as commonly prescribed antidepressants (obviously discuss any medication changes with your doctor).
2. Improved energy levels and focus. Research at the University of California showed negative ions normalize serotonin levels in the brain, potentially improving a person’s positive outlook and mood.
3. Better sleep. A French study found using negative ionizers could help you to sleep better. This is once again due to their positive effects in normalizing serotonin production in the brain.
