Headaches & Migraines

. External Triggers
Sunlight
The glare of the sun can trigger headaches – tension, cluster or
migraines. The heat from the sun could dilate blood vessels and
generate a migraine. Other bright lights like disco and flickering lights
can also lead to headaches.
Eyestrain
When muscles around the eye area contract, this means that
eyestrain has set in. This may happen just by staring at a computer
screen for long periods without taking a break, or when trying to read
small or fine print from any reading material. If an individual is doing
work that requires extended times of focusing and concentrating, he
must take five minute regular breaks so that muscles around the eyes
do not become strained.
Noise
Noisy, repetitive sounds from machinery or from other
residential or industrial source can cause headaches and migraines.
Loud music or even yelling qualifies as a trigger factor. With or
without getting headaches or migraines, people should avoid loud
noise since it may cause not only headaches, but also loss of hearing
in the long term.
