Environmental Triggers You Might Overlook
Weather, light, air and smells are easy to dismiss because we cannot control them. But knowing your patterns makes it easier to plan around them.
When people think about migraine triggers, food and stress usually come to mind first. The environment around us gets less attention, partly because it feels out of our hands.
Yet for many people, the setting they are in plays a real role.
Weather and changes in conditions
The American Migraine Foundation lists weather changes among the ten most common triggers. Many people report sensitivity to shifts in temperature, humidity or air pressure, or to very hot days.
As the Foundation puts it, we cannot control the weather. What we can do is plan: run errands earlier on hot days, keep water close, and be a little more careful with the rest of the routine on days when you know conditions are difficult.
Light, indoors and out
Bright sunlight, glare from snow or water, flickering fluorescent tubes and screens are all frequently mentioned. In the Nordic countries, the contrast between long, dark winters and very bright spring light is something many people notice.
Air and smells
Strong smells are another common trigger: perfume, cleaning products, paint, petrol and cooking smells. Stuffy rooms and poor ventilation are often mentioned in the same breath. Opening a window or taking a short walk outside can make a difference to how a long day feels.
Water and heat
Dehydration is on almost every list of common triggers, and it is easier to become dehydrated on hot days, during exercise or when travelling. WHO also highlights staying well hydrated among its lifestyle recommendations.
Travel and changes of scene
Travel combines many of these factors at once: different light, dry air in planes, irregular meals, less sleep and new surroundings. Planning a few anchors, such as water, regular meal times and a fixed bedtime, can help keep some stability in an otherwise unpredictable day.
Your environment, your pattern
Triggers differ a lot from person to person, and something that affects one person may not affect another at all. NHI.no lists common examples, but stresses that individual patterns vary. That is why your own observations are so valuable.
A simple way to start is to add a short note to your diary on days with an attack: the weather, where you were, what the air and light were like. Over a few months, patterns often appear. Our free SinaVita diary app includes a notes field for exactly this.
