The 27th Steamtown Marathon is three months away and, despite the warm weather, many local runners are deep into training. With serious heat waves of summer, any prolonged endurance activity in minimal to moderate heat can be dangerous if not prepared. Adequate hydration is critically important, not only to those training for a marathon but also for other outdoor endurance activities such as cycling, hiking, long distance power walking, etc
Next to oxygen, water is the nutrient most needed for life. A person can live without food for a month, but most can survive only three to four days without water. Even though proper hydration is essential for health, water gets overlooked as one of the six basic nutrients. Dehydration occurs when the amount of water taken into the body is less than the amount that is being lost. Dehydration can happen very rapidly (i.e. in less than eight hours); the consequences can be life threatening and the symptoms can be alarmingly swift.
In the body, water is needed to regulate body temperature, carry nutrients, remove toxins and waste materials, and provide the medium in which all cellular chemical reactions take place. Fluid balance is vital for body functions. A significant decrease in the total amount of body fluids leads to dehydration. Fluids can be lost through the urine, skin, or lungs. Along with fluids, essential electrolytes, such as sodium and potassium, are also perilously depleted in a dehydrated individual.
The risk of dehydration is not limited to endurance athletes and outdoor enthusiasts. Dehydration is the most common fluid and electrolyte disorder of frail elders, both in long term care facilities and in the community! Elders aged 85 to 99 years are six times more likely to be hospitalized for dehydration than those aged 65 to 69 years.
Is water adequate to prevent dehydration? Will a sports drink improve my performance? While some answers to these questions apply generally to all, others vary according to the temperature, humidity, length of time and intensity of the activity and condition of the athlete.
Proper hydration is essential for the comfort and safety of the recreational and serious athlete. Hydration is critical to maintain cardiovascular function, body temperature and muscle performance. As temperature, humidity, intensity, and duration of exercise increase, so too does the importance of proper hydration. Excessive sweating can lead to a loss of blood volume which requires the heart to work much harder to circulate you blood through your body.
Dehydration is a major cause of fatigue, loss of coordination, and muscle cramping leading to poor performance. Prehydration, (drinking before exercise) is the first step in preventing dehydration. Marathon runners, other long-distance runners, and cyclists often prehydrate1-2 days before a big event. Rehydration, (drinking during or after exercise) is the second step in preventing dehydration. While athletes may be more vulnerable to dehydration, all persons engaging in exercise would benefit from increased performance, delayed muscle fatigue and pain by maintaining adequate hydration. Proper prehydration would include drinking 12-16 ounces of water 1-2 hours before exercise. Athletes with other health issues should consult their family physician before engaging in long distance endurance sports.

Last week in Health & Exercise Forum, we discussed dehydration as a potentially life-threatening problem, especially in those over 60. Summer heat and humidity are here and the risk of heat related illnesses are greater than normal. Age, diet, illness and medications are some of the many reasons why elders suffer from dehydration not only in the summer heat, but year round. Furthermore, age related changes in 50-60 year olds can also make one vulnerable to dehydration, especially if they are active and exercise in the heat.
It is widely accepted that the best treatment for dehydration is prevention. One must take a proactive approach to ensure and/or encourage adequate fluid intake, especially with age and in high temperatures. Consider some of the following practical tips to promote optimal hydration.
Remember, knowledge and awareness of the symptoms of and the prevention of dehydration can reduce unnecessary hospitalizations and maximize health and well-being for the elderly and not-so-elderly individual.
Visit your doctor regularly and listen to your body.
Keep moving, eat healthy foods, exercise regularly, and live long and well!

Summer heat and humidity are here and the risk of heat related illnesses are particularly high for those over 65, especially dehydration. Age, diet, illness and medications are some of the many reasons why elders suffer from dehydration not only in the summer heat, but year round. Furthermore, age related changes in 50-60 year olds can also make one vulnerable to dehydration if they are active and exercise in the heat. Not long ago, a local medical professional and good friend of mine was hospitalized for several days due to dehydration and associated illness. He is an active, fit, healthy 59 year old who continued his daily running for exercise during the June/July heat wave.

Dehydration is the most common fluid and electrolyte disorder of frail elders, both in long term care facilities and in the community! Elders aged 85 to 99 years are six times more likely to be hospitalized for dehydration than those aged 65 to 69 years. More than 18% of those hospitalized for dehydration will die within 30 days, and associated mortality increases with age. Men appear to dehydrate more often than women and dehydration is often masked by other conditions.
Elderly individuals are at heightened risk for dehydration for several reasons. Compared to younger individuals, their regulatory system (i.e. kidneys and hormones) does not work as well and their bodies have lower water contents. The elderly often have a depressed thirst drive due to a decrease in a particular hormone. They do not feel thirsty when they are dehydrated. This is especially true in hot, humid weather, when they have a fever, are taking medications, or have vomiting or diarrhea. They have decreased taste, smell, and appetite which contribute to the muted perception of thirst. Because of dementia, depression, visual deficits, or motor impairments, elderly persons may have difficulty getting fluids for themselves. Many elderly individuals limit their fluid intake in the belief that they will prevent incontinence and decrease the number of trips to the bathroom. The medications that they are taking (e.g. diuretics, laxatives, hypnotics) contribute to dehydration.
Elders may suffer headaches, fainting, disorientation, nausea, a seizure, a stroke, or a heart attack as a result of dehydration. The minimum daily requirement to avoid dehydration is between 1,500 (6.34 cups) and 2,000 ml of fluid intake per day. Six to eight good-sized glasses of water a day should provide this amount. Better hydration improves well-being and medications work more effectively when an individual is properly hydrated. Those who care for the elderly whether at home or in a health care facility need to be alert to the following symptoms (but these symptoms apply to both young and old):
Plain old tap water is a good way to replenish fluid loss. Some energy drinks not only have excess and unneeded calories but also contain sugar that slows down the rate at which water can be absorbed form the stomach. Consuming alcoholic and caffeinated beverages actually has an opposite, diuretic effect!
Visit your doctor regularly and listen to your body.
Keep moving, eat healthy foods, exercise regularly, and live long and well!

According to the United States Environmental Protection Agency, NEPA and all of Pennsylvania is experiencing a change in climate as indicated by a half a degree (F) in temperature, more frequent and heavy rainstorms and the tidal portion of the Delaware River is rising one inch every eight years. Last summer was one of our hottest on record and this summer has produced a several heat waves with more expected. For those without air conditioning or access to a lake or pool, it will also be remembered as record setting warm temperatures. A local reader who cares for her elderly mother wrote to express her concern about dehydration in the elderly. Age, diet, illness and medications are some of the many reasons why elders suffer from dehydration not only in the summer heat, but year-round.
