Sleep, exercise and diet
Everyday habits that can help, and the claims to be wary of.
Everyday habits that help
- Sleep: sleep problems are very common with ADHD and can make symptoms worse. A regular routine, less screen time before bed and a dark, quiet bedroom can help. Talk to your GP if sleep is a problem.
- Exercise: NICE recommends regular exercise. Many people with ADHD find movement helps with focus and mood.
- Diet: a balanced diet and regular meals are important, especially if medication reduces your appetite.
What isn't recommended
You may come across lots of claims about ADHD "cures". NICE says:
- cutting out artificial colourings and additives should not be advised as a general treatment for ADHD
- there isn't enough evidence to recommend elimination diets or fatty acid supplements (such as omega-3 fish oils) as a treatment
If you notice that a particular food or drink seems to affect you or your child, keep a diary and talk to your GP, who may refer you to a dietitian.
