Herbal supplements
World wide use of herbal medicine and supplements is increasing, offering some health improvements including sleep disorders remedy. This may include SOI (sleep onset insomnia) and WASO reduction, relaxation and reduction of nightmares, deeper sleep and higher sleep quality in general. This page reviews existing literature on herbal stimulants or supplements effects on sleep.
Sleep disturbance and WASO reduction
WASO most commonly occur primarily during polyphasic adaptation, which lasts around 4-8 weeks, so it's a normal experience and doesn't require treatment or any other means of reduction. However, for people with chronic WASO-insomia, they can take place even after polyphasic adaptation, or even outside of polyphasic sleep. As the studies show, they might have a possibility of sleep disturbance reduction by these supplements:
- Passiflora incarnata tea[1] (tested with PSG, diary, placebo control group)
Sleep onset insomnia
During polyphasic sleep adaptation, sleep onset is common for daytime naps/cores, and one shouldn't take action to reduce it artificially. After adaptation, sleep onset usually is <5 minutes for naps and <15 minutes for cores. However, for people with chronic sleep onset insomnia this might not be the case. This is especially noticeable with high total sleep time schedules, like extended Biphasic ones, non-reducing polyphasic schedules or Biphasic-X. If you still have difficulties falling asleep after 8+ weeks on a schedule, these supplements might be helpful:
- Ayurvedic supplement[2] (statistically significant decrease in reported sleep latency of 16.72 min as compared to placebo)
