Why Do I Lose Track of Time When Working on Tasks? 

Many people with ADHD describe “time blindness,” the feeling that hours can slip by unnoticed, or that time speeds up or slows down unpredictably. According to NHS guidance and NICE NG87, this is not laziness or lack of discipline; it is a recognised part of how ADHD affects the brain’s executive functions, which manage planning, sequencing, and time awareness. 

Why Time Feels Different with ADHD 

Executive dysfunction makes it difficult to estimate how long tasks will take or to notice when too much time has passed. This links directly to time blindness to a reduced internal sense of time passing. Research in PubMed (2024) explains that ADHD alters how the brain’s frontal networks coordinate planning and timing. When you are absorbed in a stimulating activity, dopamine regulation differences can trigger a state of hyperfocus, where concentration locks in and the outside world, including the clock, fades away. 

What NHS and NICE Say 

The NICE NG87 guidance notes that attention regulation and poor time management are core features of ADHD. The NHS advises that a combination of medication and behavioural strategies can help manage these challenges. Stimulant medicines such as methylphenidate improve executive function, while non-drug approaches like structured routines and timed work intervals strengthen external time awareness. 

Practical Ways to Stay on Track 

• Use external timers to set phone alarms or visual countdowns to externalise time. 

• Break big tasks down into short, focused segments with clear stop points. 

• Schedule movement or check-in breaks to “reset” attention. 

• Try ADHD-focused CBT or coaching, which builds personalised strategies for organisation and time perception. 

If you are finding time management or focus especially difficult, a professional ADHD assessment can help identify underlying patterns and tailored support options. You can explore private assessment options with ADHD Certify, a trusted UK provider offering affordable online ADHD assessments for adults and children, rated “Good” by the CQC. 

Takeaway

Losing track of time is a recognised part of ADHD’s executive-function profile, not a character flaw. With the right combination of medication, structure, and behavioural tools, it is possible to regain control over time and reduce the daily stress that time blindness brings.
