When Your Bipolar Brain Runs on a Different Clock
Episode Overview
- Circadian rhythm disruptions are extremely common in bipolar disorder and can affect mood even during periods of apparent stability.
- There is a crucial difference between insomnia and a decreased need for sleep, and recognising this can help spot hypomania early.
- Evening chronotypes often live in biological jet lag, making regular routines and light cues vital for mood stability.
- Simple daily anchors – a consistent wake-up time, morning daylight, and regular meal and sleep cues – support the brain’s internal clock.
- Changes in sleep patterns are a key early warning sign, and reaching out to a care team at that stage can reduce the severity and length of mood episodes.
“Medication and lifestyle choices are not enemies. They are co-pilots.”
What drives someone to seek a life that actually fits their bipolar brain, instead of wrestling against it every day? In this episode of *I'm bipolar. Now what?*, host Louise Barnett takes a friendly but firmly practical look at how the brain’s internal clock can throw moods wildly off course – even from something as small as a one‑hour daylight saving change.
You’ll hear Louise break down circadian rhythms in plain language, comparing the body to a big office where sleep, hormones, and emotions all rely on a strict CEO: your internal clock. She explains why up to 70% of people with bipolar disorder show circadian disruptions, and how that’s baked into biology rather than just being about “bad choices” or laziness.
Louise talks through the difference between insomnia and that classic hypomanic “decreased need for sleep”, describing both from her own experience and why one feels like torture and the other feels like you’ve “just drank four Red Bulls”. She also touches on bipolar depression, hypersomnia, and how staying inside all day quietly robs the brain of the light signals it desperately needs.
Her former life in restaurants, late nights, heavy drinking and drugs becomes a powerful illustration of what long-term biological jet lag can do to a sensitive nervous system. She contrasts that with her decision to leave corporate America and redesign her days around her bipolar needs, including medication, therapy, sobriety and lifestyle as co‑pilots rather than rivals.
Grounding everything is simple, doable advice: three anchors for your daily clock, like a non‑negotiable wake-up time, morning daylight, and consistent meal and sleep cues. Louise keeps it realistic, stressing progress over perfection and urging people to contact their care team when sleep patterns start to shift, rather than waiting for full crisis. If your mood seems to swing with every late night or time change, could your internal clock be the missing piece you’ve been overlooking?
