For me, the only thing that's had a positive effect on my night terrors is making sure my body temperature doesn't get too hot while I'm sleeping. I make sure I keep relatively cool which somehow keeps the nightmares at bay. Otherwise away I go, ranting and raving making all kinds of creepy noises, yelling!!

So, yes. Maybe he could monitor his body temperature to see if getting too hot while sleeping is a trigger.

All the best Aubrey43.
