Will moving closer to the equator cure my wife's SAD?

My wife has had serious bouts of depression for the last 4 winters and we are certain that it is caused by the lack of sunligt from living in the UK. We are doing a number of things to combat the depression, excercise; lightbox; controlled diet; vitamin and fish oil suplements and they are helping her cope. However it is only a plaster over a gaping wound and we are strongly considering moving closer to the equator. Does anyone have any first hand experience of moving from the UK (or similar climate) to a much sunnier climate? We are currently considering Australia and the southern most parts of the Mediterranean.
Feedback would be greatly appreciated.

South of France does it for us, lots of blue sky days, and even the shortest day is 9 hours long. (And you can get here by train easily)

yes it is true that the closer you are to the equator the better it is for sad sufferers

Yes it does work. I lived in Mallorca for 6 years and had no problems. Infact lost weight, felt great, had my own business etc. Moved back here 2 years ago and feel crap! Got SAD really bad, bad depression, put on 5 stone, turn off my phone to avoid working, some sleep at night, back to bed in the day and really lethargic etc. frustrated I have not got the funds to move back to Spain

Hi all.
Just wanted to express my gratitude to you all. I've had SAD my whole life--I live in Maine...short summers and endless winters. My husband and I have been thinking a lot about picking up and moving some place warm and sunny. I just can't handle much more of this oppressive sadness and social withdrawal. I'm like a hermit for days on end. Whenever we talk to our friends and family about the plan to move, no one supports us. If you haven't had SAD you can't understand. Thankfully you all do. I'm sitting here crying as I read this comments because they are so validating. I don't feel alone and that feels wonderful. Thank you again :)

Moving closer to the equator is the most effective cure for SAD! I know from experience. Growing up in Missouri I thought everyone felt off in the winter. Each year it got worse. Until I realized this was not normal. Later I got to live in Florida, South Texas, and the Virigin Islands. I had no depression at all. Now I'm back in the Midwest, it's November and it's creeping up on me...I feel like I have to fight the darkness from entering in by surrounding myself and filling myself with light....and there's just not enough.

I use to live in Madrid and never had SAD there. I was there last week in was 20/30C everyday as they had a heatwave, I woke up in a good mood, early without any problem and needed very little sleep, whilste in London I do. Moving to Southern Europe or even Morroco is a very good idea. I think the same regarding one of the other bloggers... Australia is far if that is the only reason stick to the EU.

My husband, daughter, son, and I all have seasonal depression - and we live in North Carolina! I couldn't imagine dealing with it in Maine. I did live for a year in Boston, and I'm not sure I really smiled much from November through March.

People who don't have it can't really understand. I also think there are quite a few people who have it and don't know it, particularly if it comes out as being cranky rather than depression.

I live in maine too. we are moving to Georgia in December. Have lived in maine 17 years and have battled the depression every year since. Everyone things we are crazy by moving.

Good plan!
