Hydration: Fueling the Runner - Why it's Important

All runners know that adequate hydration matters. When on a run, [hydration](https://www.healthwords.ai/us/explore/article/preventive-and-general-health/travel-health/hydration-in-a-nutshell) helps because it slows the rate at which fatigue sets in. From how limber we feel, to how quickly we tire, hydration can be the difference between a sluggish run or a new personal best. Let’s take a look at how it works.

Dry Skin: Causes, Treatment & Prevention Tips

Dry skin – sometimes called **xerosis** by doctors - is a condition (not necessarily a disease) where the skin is red, scaly and itchy. The problem is usually worse in autumn and winter, and dry skin is most common on the face, hands, arms and legs. As we age, dry skin becomes more likely. It is not a serious problem usually, but can be uncomfortable and unsightly. Ageing, living in dry, cold or low-humidity climates and bathing or showering frequently make it more likely to occur. It affects both sexes, and is more common in Caucasian skin than those whose skin has a higher oil content, such as with Afro-Caribbean or Mediterranean skin.

Dry skin can be intensely itchy. It feels rough and flakes easily. Cracks and redness can form in more severe cases. Children can be particularly at risk, and this may take the form of [eczema](https://www.healthwords.ai/us/explore/article/skin-and-external-care/skincare-scalp/eczema) - where inflammation of the uppermost layer of skin causes dryness, and this is most likely to appear on the insides of elbows or the backs of knees. Eczema may run in families or run alongside asthma or hay fever.

Hydration, Dehydration & Heatstroke: Treatment

Ensuring adequate [hydration](https://www.healthwords.ai/us/explore/article/preventive-and-general-health/travel-health/hydration-in-a-nutshell) to help our bodies remain healthy can be a tough task, especially in hot conditions, and during strenuous activities or exercise. Hot temperatures and increased water and salt losses can lead to dehydration. Mild dehydration may be felt as thirst, headache, mild dizziness, reduced need to urinate, and dry skin. In its more severe form, dehydration can result in reduced alertness, fatigue, muscle cramps, loss of consciousness, and long-term damage to your kidneys.

Hydration in a Nutshell: Importance and Tips

Hydration, in its simplest form, is to supply and retain water in the body's tissues. Take in too little water, and you risk dehydration, making it hard for the body to carry out essential functions. And with loss of water, you lose essential salts and minerals, causing further turmoil in your body.

We've all experienced mild dehydration at times, like when the weather is hot, or we are doing a sweaty workout. Fighting a fever or a stomach bug also leaves you lacking hydration.

But you might have overlooked the toll a flight can take on your body. An airline cabin draws air in from the upper atmosphere for us to breathe in, and this is very dry. The cabin air can be less humid than the Sahara Desert, and you actually lose water through your breath. Telling signs can be a dry feeling in your nose and throat, your contact lenses feeling scratchy, and you might be passing urine less, or it's dark and strong-smelling.

You might feel thirsty, but this is actually a late sign, as when thirst sets in, your body is already 2% dehydrated. You need to work hard to replace this. Your body will work best if you can plan ahead to avoid dehydration, rather than playing catch-up.

If you're traveling with little ones, they have a higher body surface area and breathe a bit faster, so they can become [dehydrated](https://www.healthwords.ai/us/explore/article/preventive-and-general-health/travel-health/hydration-dehydration-and-heatstroke) even more quickly, and salt imbalance follows. It can be tempting to let them snooze through the flight (and give you some peace), but feeling tired and sleepy can also be a sign of dehydration, so make sure they have topped up before nodding off.

Oral Rehydration Salts: How They Work and When to Use

Oral rehydration therapy (also known as [oral rehydration salts](https://www.healthwords.ai/us/shop/products/ors-hydration-tablets-24-soluble-tablets-blackcurrant) or solution) is used to prevent and treat dehydration. Around the world, it is used to prevent serious illness and death from diarrhea. It has been reported to reduce the risk of death by more than 90%. It is considered so important that it is a part of the World Health Organization's list of essential medicines.

Oral Rehydration Solution (ORS): How Does it Work?

Oral rehydration solutions are a balanced formulation of [electrolytes](https://www.healthwords.ai/us/explore/article/nutrition-and-wellness/nutrition-metabolic-health/electrolyte-replacement-products-426) and minerals such as:

- sodium 
- potassium 
- magnesium 
- phosphorus 
- chloride 
- small proportion of glucose 

They can be added to water to make a solution that’s readily absorbed by the body. The electrolyte composition of ORS is carefully balanced to mimic the electrolyte concentrations found in the human body, facilitating optimal absorption and retention of fluids.
