Around sleep, do you get caught bouncing between the threat and drive system - worrying about sleep and striving to fix it?

Draw your three circles as they usually look at bedtime: how large are threat, drive and soothe? Now make a “grow the soothe” list of three things that genuinely help you feel settled, connected or content.

Session Recap

01

Threat prioritises safety

The threat system responds to the possibility of danger, not only to danger that is actually present. Sleep-related worry can therefore keep the brain alert even when the body is physically safe.

02

Drive keeps the body active

The drive system energises planning, striving and problem-solving through seeking a solution to a sleep problem. Trying harder to achieve sleep can therefore create the activation that makes us more alert and rest more difficult.

03

Sleep needs a different balance

During ordinary daytime activity, all three systems have useful roles. A sleep-ready state generally involves greater soothe alongside relatively little threat and drive. The soothing system naturally helps down-regulate threat and drive. Strengthening soothe can reduce the cycle of worrying about sleep and striving to fix it.
