Yes, the Sun changes sidereal signs pretty much every year on the same day. I don't have all the answers to your questions, as I'm only at the beginning of this research. I'm still looking into what causes or prevents the larger cycles, why one year yes, and the other no, but I hardly made any progress there. However, I found that many peaks occur when the Sun changes signs. Also, often cycles start then. Another way to convince yourself is keeping a detailed record of peaks and then comparing it to solar ingresses by using an ephemeris. If you wish to know more, best take a look the pdf attached, as it includes my findings up till now. For your convenience, I've listed the solar ingresses for the rest of the year.

The reason your CH cycle started on August 17 is because on that date, the Sun changes signs (sidereal Cancer to Leo) . (Don't know why it stops on September 1 though.) Check the "Medical Almanac" I prepared for July-December 2025 - pdf attached. Medical Almanac 2025 solar disorders.pdf

In the tradition of the old “Almanac” makers, I thought it might be nice to create a “Medical Almanac” that looks at the sensitive times for (cluster)headaches. As a first publication, it starts modestly, and covers only the second half of 2025 (July-December). It shares the research and the theory behind it and marks the collective dates when one may - or may not - experience peaks in intensity. If you’re interested, whether to check if there’s any corresondence with your own CH peaks, or just curious to see what the hell this is all about, get in touch by pm and I’ll send you a pdf copy (free).

Actually, sunlight IS good for the brain and CNS disorders. https://digital.kenyon.edu/cgi/viewcontent.cgi?article=1043&context=skneuro

Hi, I expected there to be a peak in intensity in CH. From studying records of CH patients, I noticed peaks corresponding to the dates when the Sun changes signs, and even more so if it is afflicted at the same time. In this case (mid May), it was afflicted by Mars. But this time, people didn't experience any noticeable peak, so I need to look deeper into it.

Instead of debating the issue. Let’s see what happens this Wednesday and Thursday. To anyone in a cycle right now: it would be helpful if you could give us feedback and share here if you’re indeed experiencing a rise in intensity of CH attacks during these days.

@AlvaroYou're laughing? Academic research has shown that CH attacks have a circannual rhythm. You mentioned that in 2022 you had a few CH attacks around January 3rd, 4th, if I'm correct? There were 2 solar influences around that date: The Earth was at perihelion - its closest point to the Sun. Mars was at the same parallel to the Sun (see picture attached). If you wish, I'm always happy to take a closer look at your personal cycles. Send me a dm Stijn

Hi, Some of you may be aware I did some research into the timings of CH cycles and remember that it is connected to solar cycles. Recently, it has become more and more obvious that the intensity of CH attacks "peak" whenever the Sun transitions from one sign into the next - whether this be in the sidereal or the tropical zodiac. If around the same day, the Sun is also "afflicted" by certain other planets, the effect is even stronger. In regards to this, I want to make a "forecast" for later this year. Anyone in a cycle around that time, beware of MAY 14-15 2025. The reason: around the middle of May, the Sun will be Ingressing into sidereal Taurus (sensitive point of transition), On top of that, Mars will also be in parallel to the Sun (affliction).

Hi everyone. Some of you may know me from a few posts in the closed section of this Forum earlier this year, and remember that I’ve been doing some amateur research into the circadian and circannual rhythms of clusterheadaches. After months of research, I was able to identify what I think triggers migraine and CH cycles. Considering how to make this information generally available, I decided to write a story about it. (But don’t get it twisted: the story may be fictional, but the science comes from actual research.) Anyway, here it is: THE CYCLES OF THE BEAST Description: During a chance encounter in Lisbon, Will and Laura come to learn of a disease that has been described as “the worst physical pain known to man” - like being stabbed through the eye with an icepick. Patients call it “The Beast” and it attacks its victims in cycles that can last for months, to then mysteriously vanish as sudden as it appeared. When they spot a pattern in the daily and seasonal peaks of the Beast, Will and Laura know there’s a job waiting for them. You can get it through amazon here https://a.co/d/enpEemE
