min
Warm shower
Fall asleep faster. Sleep more soundly.
Use this when
When you want to sleep well tonight and you have 10 minutes to spare about an hour or two before bed.
After this
Your body will start cooling down in a way that signals to the brain it is time to sleep. Most people find they fall asleep faster on nights when they do this.
You will need
Access to a warm shower.
The why
A warm shower raises body surface temperature, dilating blood vessels in the hands and feet. This allows heat to escape from the core, which accelerates the temperature drop the brain uses as a signal to initiate sleep. A meta-analysis of 17 studies found this shortened time to fall asleep by an average of 36%.
