Going to bed and waking up at the same time daily — even on weekends — is one of the strongest levers for sleep quality, reinforcing your circadian rhythm more than total hours alone.

A cooler room (around 18-20°C / 65-68°F) and minimal light both support the body's natural drop in core temperature that helps trigger sleep.

Caffeine's half-life is roughly 5-6 hours, so an afternoon coffee can still be affecting sleep at night. Alcohol may help you fall asleep faster but fragments sleep later in the night.

Bright screens close to bedtime can delay melatonin release — dimming lights and screens in the last hour before bed helps signal to your body that it's time to wind down.

A consistent pre-sleep routine (reading, stretching, journaling) cues your brain that sleep is coming, the same way a routine helps a child fall asleep.

If your mind races at bedtime, writing tomorrow's worries or to-do list down earlier in the evening — a "worry dump" — can reduce the mental load your brain tries to process at bedtime.
