About this routine

In his sleep research and book Why We Sleep, neuroscientist Matthew Walker stresses that bedroom environment directly dictates sleep quality. Following a Matthew Walker sleep routine means turning your bedroom into a dark, cool, and quiet space built strictly for rest.

This 20-minute reset focuses on concrete environment adjustments. Setting the thermostat to roughly 65 degrees Fahrenheit aids the drop in core temperature necessary to initiate sleep. Blocking ambient light and hiding bright LED displays ensures melatonin production remains steady.

Walker also advises turning clock faces away from view to eliminate time-monitoring anxiety if you wake during the night. Removing smartphones and tablets from immediate reach keeps bright light and mental stimulation away from your sleeping zone.

Why this routine works

  • Cooler room temperature supports natural core body cooling
  • Complete darkness prevents light-induced nighttime awakenings
  • Hiding clock faces reduces clock-watching anxiety at night
  • Removing screens eliminates blue light and cognitive stimulation
