Risks of Dehydration
If one has ever been feeling thirsty, most probably he or she has already been dehydrated. The sensation of thirst appears when certain nerve receptors located at the level of the hypothalamus which is a very important structure of the brain are alerted by too high a concentration of blood. This is the sign that you are already dehydrated and it is a signal to take very seriously. Risks of dehydration is especially bad for infants and senior citizens, they are also the most vulnerable. Infants are particularly troubled because their bodies are made up of 70% water and have very few reserves. In addition, as their immune system is immature, they are prone to childhood diseases such as fever, diarrhea and vomiting all of which promote water loss. In senior citizens prevalence of common diseases such as diabetes and high blood pressure and their medication can be the reason or the aggravator for dehydration. Also senior citizens in many instances don’t feel the thirst hence their water intake is minimal at best.
Symptoms of Dehydration
At first, the beginning of dehydration is feeling of simple thirst. Often ignored other warning signs follow. If dehydration is not quickly corrected, the sensation of thirst becomes intense, the production of sweat and urine decreases. Highly concentrated urine is one of the symptoms of dehydration, other symptoms such as fever, headache, dizziness, accelerated pulse rate, drop in blood pressure, nausea and vomiting may occur in the absence of quick rehydration. The brain cells being particularly sensitive to dehydration, thus in case of dehydration an individual will suffer from confusion, convulsions and disorders of consciousness. In addition to the symptoms of dehydration one may also suffer from symptoms, because of which dehydration has taken place in the first place, for instance stomach ache if the dehydration has been caused by diarrhea.
How to Prevent and Treat Dehydration
During heat wave in summers or hot weather and other times when one is at risk of dehydration it is strongly advised to focus on prevention. Firstly keep rehydration yourself by drinking water every quarter of an hour. When spending an extended period out in the sun during summers one should rehydrate before, during and after the session. Be careful and reduce the consumption of caffeine and alcohol that promote dehydration. In the event of a heat wave, stay indoors preferably in a cool room. Wear a simple, loose-fitting cotton T-shirt. Cool yourself through a cold shower and avoid venturing out during the hottest time of the day. Contrary to the popular belief air conditioning is not the best solution. To cool the air that comes into a room, spread a wet sheet in front of the windows. Do also ventilate, preferably with a ceiling fan. Open the windows at night and fight against all sources of external heat by equipping your windows shutters or failing with thick and light-colored external blinds, to close during the day and to reopen as soon as the outside temperature is lower than that which prevails inside of the house. Put green plants in the main rooms, on the balcony and in the immediate vicinity of the house to create a microclimate limiting the warming of the indoor air. Finally reduce your sources of heat inside the home, forgetting the halogens that heat almost as much as a radiator. Also avoid activities that give off heat and energy such as oven or gas lit for hours, ironing, appliances on the night light, it’s best to unplug them. In case of extreme dehydration or unconsciousness seek immediate emergency help.
