Glaring light, whether it's artificial or natural, can cause migraines. For this reason, Debbie Shipley from The Migraine Trust recommends choosing matte finishes rather than gloss when decorating, to reduce the amount of light bounced around the room.
'Sitting under intense, bright light or being exposed to a flicker effect can also cause headaches, fatigue and migraines,' says lighting expert Michael Meiser, president of Lumilum.
