Fluid Guidance For Children

The amount of fluid your child needs in a day to stay hydrated depends on their weight. See below for guidance:

• for a child who weighs 010 kg, the amount of fluid required per day is 100 ml/kg,
• for a child who weighs 1020 kg, the amount of fluid required per day is 1000 ml plus 50 ml/kg for each kg over 10kg,
• for a child who weighs more than 20 kg, the volume of fluid required per day is 1500 ml plus 20 ml/kg for each kg over 20 kg, (for example, 1600 ml/day if the child weighs 25 kg

Why Dehydration Is More Common Among Seniors

Maintaining a healthy balance of water and electrolytes can be an even more complex process for seniors than it is for younger people. As a result, older people are more likely to get dehydrated. And the complications of dehydration in the elderly can be more serious.

According to an article in Frontiers in Molecular Biosciences, dehydration is one of the top 10 reasons for seniors to be hospitalized. And for hospitalized seniors, dehydration can lead to longer stays in intensive care units, increased hospital readmissions, and more placements in long-term care facilities.

Why does the risk of dehydration increase with age? Older adults are prone to dehydration because they can experience several health or lifestyle conditions that lead to low fluid levels. Many seniors experience at least one of the following risk factors:

When To See A Doctor

Since many people dont show symptoms a regular check-up is the best method. However, people under the high-risk group should see a doctor frequently and the high-risk group includes:

Weird Things That Can Mess With Your Heartbeat

Learn the top triggers of heart palpitations, plus what to do about each one.

A few weeks ago I thought I was having a heart attack. My morning started out normal: I woke up at my usual hour, feeling what I thought was a little bit of tiredness. But as I went about my morning routine, things grew scary. I broke out in a cold sweat as I brushed my teeth. My skin turned white as paper. And then, scariest of all: my heart was pounding like crazy. As a health writer I know these arent textbook signs of a heart attack, but I also know that dangerous cardiovascular events in women can be more subtle than those in men.

Later that day I went to urgent care, but an EKG and blood tests showed nothing out of the ordinary. Turns out my heartbeat went haywire as a result of a side effect from a medication. The technical term for this: heart palpitations, which can be brought on by many things.

How Much Should You Drink

So its important to stay hydratedbut what exactly does that mean? Guidelines from the Institute of Medicine of the National Academies recommends 2.7 liters of water daily for women and 3.7 liters for men. But most experts agree fluid intake varies person to person and there isnt a definitive answer to how much is enough to ensure proper hydration.

Some people say that you should take your weight, divide it by two, and thats the number of ounces you should drink per day, Dr. Steinbaum says. But it depends on your lifestyle and what your sources are. For instance, youll likely need more water if youre physically active or work outdoors in a hot climate. Youll also have greater fluid needs if you have a chronic illness that comes with frequent urination or sweating, like diabetes, kidney problems , and/or cystic fibrosis.

Whats more, seasonal changes affect your drinking habits in a way you might not think. In colder weather, your brain does not detect the blood flow decrease and sodium increase that accompany a drop in fluid intake. Even though you still need fluids, youre not feeling like you need to drink them, so you dont replenish your liquid intakeleading to winter-time dehydration. According to research published in Medicine & Science in Sports & Exercise, cold temps actually reduce your thirst sensation by up to 40%.

Dehydration symptoms include:

• Urinating and sweating less than usual

Can Dehydration Cause High Blood Pressure And Heart Rate

There is a link between dehydration and blood pressure and heart rate in addition to the link between dehydration and heart disease. Dehydration strains the heart and the quantity of blood passing through the body or blood volume lessens during dehydration and to compensate, the heart beats with increased rate thereby increasing blood pressure and heart rate.

Slow Capillary Refill Time

Another sign of dog dehydration is it takes longer for blood to refill capillaries.

You can do a quick test by gently pressing a finger against your dogs gums until blood is blocked from the area so it becomes white. Release your finger. The white area should become pinkish again almost immediately if a dog is healthy.

In a dehydrated dog, there will be a time delay for the blood to refill, so it takes longer for the area to turn pink again.

Linking The Two Conditions

When a person becomes dehydrated, a number of problems arise. One of the functions affected, the blood pressure, drops appreciably. In response to this decrease of pressure against the blood vessel walls, the heart attempt to raise the blood pressure by beating faster. This compensation results in a lowered supply of blood to infuse the body’s tissues. This can frighten the patient and cause anxiety and panic. The fear adds fuel to the already irritable heart.

Dehydration Heart Rate And Heart Health

Dehydration causes strain on your heart. The amount of blood circulating through your body, or blood volume, decreases when you are dehydrated. To compensate, your heart beats faster, increasing your heart rate and causing you to feel palpitations. Also your blood retains more sodium, making it tougher for it to circulate through your body.

So how much water should you drink to stay hydrated? It really depends on how much your body needs. Some situations where you should drink more water include:

• If you are exercising or doing other physical activities.
• If you have certain medical conditions, such as diabetes or heart disease.

Dehydration Impacts Heart Rate And Performance

There has been some controversy lately over the effects of dehydration on health and performance in athletes. Its consequences for performance were investigated in a recent Journal of Strength and Conditioning Research study.

The researchers performed a review of the scientific literature to investigate the effects of hydration status on heart rate. They chose only studies that included comparisons of dehydration to euhydration , and conducted research specifically in the heat. The search resulted in twenty studies to include in the review.

Naturally, the idea here is that when exercise is conducted in the heat, athletes lose water, mainly through sweat. This may also apply to other sports in which water is cut to achieve a specific weight class. This topic has actually come under debate, and some believe that perhaps the consequences of dehydration have been overhyped.

The researchers chose to analyze heart rate for a couple reasons. First, heart rate is a decent gauge of health, fitness, and stress. The heart responds to a variety of physical and psychological stimuli, and the way it responds has a great deal to do with a persons wellbeing. Second, measuring heart rate is a simple test that anyone can perform and is easy for everyone to understand. Many kinds of tests require lab conditions, such as VO2 max testing, but measuring heart rate only requires a clock.

/5it Makes Your Heart Work Harder

Dehydration can lead to a drop in your blood volume level and causes your blood to thicken. This can happen when you are the slightest bit dehydrated. When your blood volume drops, the level of your blood pressure also comes down naturally. In this situation, you start to feel dizzy and lightheaded. To maintain the blood pressure level, the body constricts blood vessels and increases the heart rate, making your heart work harder to transport oxygen and other nutrients throughout the body. This condition can also lead to irregular heartbeat or palpitations.
