Headache & Dehydration
Location and symptoms
Generalised headache – headaches are one of the symptoms of dehydration.
Dehydration is caused by a lack of fluid intake or excess fluid losses. You are most likely to lose fluid through vomiting, diarrhoea, sweat and urine. Many cases of dehydration are caused by: heat, vomiting and diarrhoea (i.e. ‘gastro’), fever, vigorous exercise or strenuous activity, alcohol consumption (alcohol acts as a diuretic), travel (travellers’diarrhoea, long-haul flights – dry cabin conditions, sun exposure, physical activities and alcohol consumption) or lack of food/fluid intake.
Under normal circumstances a ‘good hydration status’ can be adequately achieved with water and a balanced diet. However, if you are at risk of dehydration, an oral rehydration solution (Hydralyte™) will have some advantages, including:
- Rehydration is likely to be more rapid
- The retention of water is better.
- Hydralyte™ is a pleasant flavoured solution, which can be more palatable than plain water, and this can make it easier for you to consume an adequate amount of fluid daily.
