Why oh why does the heat cause so many headaches!?
it raises your body temperature. In high heat situations, there is generally more dust and allergens inhaled. nasal and other respiratory problems make your body work harder to supply oxygen rich blood to the brain and rest of the body. Higher heat causes higher blood pressure as well.
Why does weakness, nausea, disorientation, headache, and low blood pressure occur during heat stroke?
First of all heat stroke is actually the most sever form of heat illness, and has a mortality of up to 10%. The more common form is heat exhaustion, which features the symptoms above. Heat illness occurs when the normal methods the body has for gettting rid of heat (and maintaining core body temp) are overrun. This usually results from a combination of factors, eg long sun exposure, over excercise and alcohol use. The symptoms occur from a number of factors. Sweating profusely will usually deplete water and sodium, causing dehydration. In addition, one of the key mechanisms the body has for losing heat is vasodilation, widening the veins near the skins surface. This has the effect of further lowering blood pressure. nausea is also typical of fever and dehydration without heat illness. weakness and disorientation can be attributed to low blood pressure and the effect of raised body temperature, and headaches due to dehydration. When the condition passes into heat stroke the mental function of the sufferer declines and the body organs such as the kidneys and liver start to suffer damage from the excessive temperature. Normal body temp peaks at 38 celsius, in heat stroke sufferers it will be 41 or over.
Is it true that sleeping with wet hair will cause headaches?
The myths that connect water, temperature and health date back to the late 1700s .Still, it seems that old wives’ tales, such the dangers of sleeping with wet hair, are hard to die off.We know now that illnesses are either caused by virus or bacteria, and that wet hair has very little to do with disease.Still, advising against sleeping with wet hair may be a good call, after all.The British Medical Journal (BMJ, for short) reported in 2008 that about 7 to 10 percent of our body temperature is released through our head. Essentially, this means that the human head is a sensitive area for body temperature.The significance of this fact is that sleeping with wet hair is likely going to drop your body temperature to a point that you will not sleep comfortably.Once the body starts cooling down, so will your limbs, hands and feet. Try to keep your body in a temperate environment as much as possible, especially at night time.Your head hurts a lot when you sip a frozen drink really fast through a straw.

Why do naps cause headaches?
I will first quote from Wikipedia for ready reference and then discuss."A power nap, also known as a Stage 2 nap, is a short slumber of 20 minutes or less which terminates before the occurrence of deep slow-wave sleep (SWS), intended to quickly revitalize the napper. The expression "power nap" was coined by Cornell University social psychologist James Maas.[7]The 20-minute nap increases alertness and motor skills.[7] Various durations may be recommended for power naps, which are very short compared to regular sleep. The short duration prevents nappers from sleeping so long that they enter the slow wave portion of the normal sleep cycle without being able to complete the cycle. Entering deep, slow-wave sleep and failing to complete the normal sleep cycle, can result in a phenomenon known as sleep inertia, where one feels groggy, disoriented, and even sleepier than before beginning the nap. In order to attain optimal post-nap performance, a Stage 2 nap must be limited to the beginning of a sleep cycle, specifically sleep stages N1 and N2, typically 18–25 minutes".In simple words we can say that an optimum nap has to be of shorter duration (~20 min), short enough to terminate before you enter a phase of deep sleep. Once you leave a sleep wave mid way, you are likely to have headache.Another reason for your headache associated with sleep may be irregular timings of sleep and awakening and sleep deficit. Your body may be in need of longer sleep to make up for sleep deficit but you have limited time available, so making it a nap and terminating it by alarm, mid way some sleep cycle, disrupting the set system. Circadian rhythm of our body, when defied repeatedly, as happens these days with many, results in cronic circadian de-synchronization or circadian disruption. Headache and grogginess are it's immediate symptoms. Late effects are many.
