Headaches can be pathologies that can really weaken us to the point of incapacitating us to face our day to day. One of the most effective ways to counteract the negative consequences of these ailments is to accurately identify the factors that trigger them. Sensitivity to light can generate or, where appropriate, intensify pain if we are not careful enough. This anomaly is more bothersome, if possible, in the summer months due to the greater presence of the sun during the day as well as the existence of a more evident luminosity.
Headaches caused by light
American researchers recently discovered that exposure to light causes reactions in a group of neurons that, curiously, are also activated when we have a migraine attack. This is an ailment that affects, as a general rule, only one side of the head and has a stinging nature. Normally it is linked to other symptoms such as vomiting, nausea and fatigue.
One of the triggers for most light-related headaches is the sunbeam itself. When these solar rays bounce off different surfaces such as pavement, computer screens, water, snow, a mirror or vehicles, the brightness that our brain perceives through the eyes increases. The longer we are exposed to these reflections of sunlight, the more the facial muscles will contract to block it, causing an increase in pain action.
If our eyes are very sensitive to light, we should consult with specialists in this organ in order to be able to take all possible precautions and avoid the numerous migraines that this factor can cause us. Wearing hats, sunglasses, staying indoors for as long as possible, drinking plenty of water, using sunscreen or cleaning screens to avoid reflections and glare are tips that can come in handy to avoid headaches caused by light.
