ADHD and Sleep Cycles

ADHD brains often have a delayed circadian rhythm, making traditional sleep schedules difficult. Understanding this connection is key to better rest.

Common Challenges

• Delayed sleep phase — naturally wired to stay up late
• Racing thoughts at bedtime — difficulty shutting off the mind
• Inconsistent sleep schedule — varying bedtimes and wake times
• Stimulant medication timing — can interfere with sleep onset

Strategies

• Consistent wake time is more important than consistent bedtime
• Dim lights 1-2 hours before bed to support melatonin production
• Physical activity earlier in the day helps regulate the cycle
• Avoid screens or use blue light filters in the evening
• Melatonin (low dose, 0.3-0.5mg) taken 2-3 hours before desired sleep time
