I have a wifi switch on a freestanding lamp in my bedroom that comes on every day at 7 am and stays on until I turn it off at night. I have found it really helps to wake me up in the morning without needing to use noisy alarms.

I also have a dog and if I don't get up right away, he sees the light and starts pestering me to take him outside.

I got the Lumie 300 and it's amazing. I immediately felt better. Like way better. Winter still sucks for other reasons, but this was a huge upgrade for my life

It wakes you up with gradual simulated sunrise. I feel like I'm back in the south where I grew up

Sad lights help. I have one on my desk and when i remember to use it it def helps. Wakes you up and feel more energized

Hii, not sure if it counts as 'dawn simulation' but I have a smart light set up to turn on gradually at the same time year round.

It helps maybe a little with SAD, but mostly helps my sleep consistency. I couldn't say for sure with all the other factors in play.

I got one of these therapy lights this year. I think it helps a bit. What I noticed most is that I wake up earlier than I usually would in Winter.

But be aware that you have to look into the bright light for 30 minutes every morning. And while you can do some stuff during that, it is kind of a chore. It also only works if you do it consistently. So it's not like you turn on the light and feel great afterwards.

I got one from Beurer and have no complaints.

I've not tried one before, but something that always sticks out to me is that a few years ago, when we were roadtripping around North Finland, every single AirBnB we stayed in had a SAD light or sunrise alarm clock (these were AirBnBs where it was someone's home, not a dedicated holiday rental). That speaks volumes to me, in much the same way that seeing all those places store vodka in their freezer was something I used when arguing with my housemates that we should also.

I tried one for a good while but can't say I noticed any benefit. What did work though was regular old SSRI medication which I'm now on year round (going off them in the summer just brings side effects) instead.

This is one of the reasons we moved south, but a powerful SAD lamp does wonders. Be sure to use it at least 20-30 minutes every day, ideally in the morning. The lamp should include instructions.

My partner uses one that you wear as glasses and the little lights shine down on your eyelids. It works for him. He used a couple of lamps before that and found that, basically, the more expensive ones work as long as you sit right in front of them.
