With temperature levels seemingly skyrocketing in many parts of the country, it is particularly important to avoid dehydration. Being outside in humid high heat for a prolonged period can result in a heat stroke. Signs of overheating of the brain may include headache, dizziness, faintness, confusion, nausea, hallucinations, and even coma. Even without the extra heat, studies are linking dehydration with a variety of brain conditions and even suggesting that proper hydration may help reduce the risk of Dementia, Parkinson’s, and Lou Gehrig’s disease. Drinking sugary drinks or colas is not particularly helpful because they trigger digestion, whereas water can begin to be absorbed immediately. And speaking of headaches, they can be an early sign of dehydration. As the cells lose water, brain tissue can begin to shrink and pull away from the skull. This results not only in discomfort, but also difficulty in thinking. Shrinkage of brain tissue is now a known factor that is linked with dementia—and that can be exacerbated in hot weather. Drink for your health! Water of course. Your level of wellness depends upon it!
