“THE ADULT ADHD CIRCADIAN CLOCK MAY BE INCORRECTLY SET BETWEEN 4AM AND NOON” WOULD EXPLAIN A HELL OF A LOT ABOUT MY ENTIRE EXISTENCE

tbh I wish I’d known this earlier on in my life. I’ve always naturally slept from 4am-12pm when my body is allowed to choose its own rhythm.

… This is EXACTLY what I fall into, too.

Does anyone have an actual source?

ADHD is related to several sleep problems, but the most frequent seems the delayed sleep phase syndrome, a disturbance of the circadian rhythm. Research of children and adults with ADHD (when compared to controls) shows that the majority of these individuals has a late sleep onset that is associated with a late onset of the sleep hormone melatonin (van der Heijden et al, 2005; van Veen et al, 2010). Melatonin is produced by the pineal gland in the brain when it is getting dark in the evening, and we wake up by light in the morning. The onset of the melatonin production helps to fall asleep. For most adults the onset of melatonin is around 9.30 pm; in ADHD children compared to controls this occurs at least 45 minutes later, and in adults with ADHD even 90 minutes (van der Heijden ea, 2005; van Veen ea 2010). After melatonin onset, it normally takes 2 hours to fall asleep, but in adults with ADHD it takes at least 3 hours (Bijlenga et al, 2013). So it does make sense that so many people with ADHD have difficulty falling asleep on time. This late onset of melatonin is driven by genes that regulate the biological clock, and those genes have been linked psychiatric disorders like ADHD and bipolar disorder (Landgraf et al, 2014). What the exact relationship is between this late sleep pattern and ADHD is still unknown.

Oh Hey Look It’s Me.

Huh.
