Dehydration
Many health experts recommend drinking 8 glasses (4 pints) of water a day and minimising alcohol and caffeine intake to stay hydrated. This will also ensure you have plenty of breaks :-)
Computer Screens
Staring at a close-range light source for hours at a time is not what we evolved for. Information on avoiding eye strain related headaches here and office headaches related to monitors here.Stress
Stress related illness is the leading cause of work absenteeism in the UK and many office headaches are stress related. Either directly or through lack of sleep and overwork. Good stress management is a HSE requirement for UK employers.Posture
Bad computer posture can lead to office headaches. I recommend this book by Paul Linden for those interested in computer posture.
Office Headache Cures
While not medical advice in my experience addressing one of the problems above will help with most office headaches (there are of course a host of other causes such as food allergies and serious illnesses). Killing your boss is another useful measure to relive office headaches...joke. Painkillers just mask symptoms so if you're needing to use them repeatedly it may worth looking for underlying causes. An alternative somatic approach to dealing with office headaches is here.
If in doubt about headaches ask a doctor. This is not medical advice.
