Circadian's cycles can cause depression?

I think my circadian's cycles are wrong , cause are months that I go to bed very late ( 5-6 am) and I wake up at 12:00/13 am .

So my times are really wrong , and I read about the circadian's cycles , can you tell me if my wrong lifestyle can cause me a strange evening/night's depression that I feel since some days?

Only at night , I feel depressed

Glad if you could help me!

The title should read "Wrong circadian's cycles can cause depression?" Otherwise you make it sound like our body's natural rhythm causes depression. That's like saying "lungs cause infection!"

Good advice. F-lux is a good app for dimming your computer screen in the evening BTW. Its warms the colour so theres less blue too. Its technically the blue spectrum of light thats tied to circadian rythmns, so as well as having dimmer lighting, getting lighting thats as "warm" as possible, like amber coloured is helpful too. You can buy special light bulbs with less blue in them too.

Hi Edgar, Regular sleep-wake cycles are important for well-being. It's very common for people who do not sleep well or at regular intervals to experience all sorts of mood problems including depression.

If you feel that your sleep-wake cycles ("circadian rhythm") are off and your symptoms are starting to interfere with your life, it's time to take some action.

First, you want to rule out drug/alcohol use, including caffeine and other stimulants or prescription drugs. If you are using these, you might consider how they are affecting sleep.

Second, you might consider some basic behavioral interventions to regulate your sleep-wake cycle. These include dimming lights significantly in the evenings (and not staring at screens), only using the bed for sleep/sex, getting out of bed for a while if you don't fall asleep in 15 minutes, as well as being very active and getting plenty of sunlight early in the day. You might also consider if you have any negative associations with feeling safe at night. Therapists certified in behavioral sleep medicine are excellent at helping people work through issues like this and you can find them here: http://www.absm.org/BSMSpecialists.aspx http://www.behavioralsleep.org/FindSpecialist.aspx

Third, you might consider seeing a medical doctor who specializes in sleep issues at a sleep center. They can do very advanced sleep studies that can tell you if something is physically wrong.

To answer your question, your issues could simply be related to your lifestyle. If you are not active, mostly staring at computer screens or tv's, using stimulants or other drugs, or simply not keeping a regular schedule by having meaningful activities and social interactions during the day, these can all lead to dysregulated sleep cycles. Good luck on your journey.

Yes they can and it is tied to falling D levels and falling free T3. I talk about this a lot at my blog. It is complex science but fascinating when you see what else it can cause.
