Is there any preventative medication for exertion / heat induced headaches that does not impair concentration. I race motorcycles and must remain alert obviously. I exert myself physically while racing and this usually results in me getting very hot and then a headache behind the forehead starts. Wetting my hair and a wet head band or cap helps relieve the discomfort but it does not cure the headache. I am 57 years of age and have suffered with this problem since juniour school sport. The usual process is i) play sport ii) exert myyself iii) get hot iv) headache starts v) headache becomes severe behind forehead vi) lead to vomitting vii) sleep viii) wake up drowsy and exhausted. I'm looking for a cure and or some control in the meantime. Thank you
