Affinity Health, a leading provider of high-quality health cover, is encouraging people to pay closer attention to their daily hydration habits, as dehydration is common and often goes unnoticed.
Water is essential for the body to function properly. It helps control temperature, support digestion, move nutrients, and remove waste. Even mild dehydration can lead to fatigue, headaches, and poor concentration.
“Hydration is one of the simplest ways to support your health,” says Murray Hewlett, CEO of Affinity Health.
“If you wait until you feel thirsty, you may already be slightly dehydrated. Drinking water regularly can help improve energy, focus, and overall well-being.”

What Causes Dehydration?

Dehydration occurs when the body loses more fluids than it takes in. This can happen for several reasons, including:

• Not drinking enough water during the day.
• Hot weather or excessive sweating.
• Illnesses such as vomiting, diarrhoea, or fever.
• Certain medications, including diuretics.
• High levels of physical activity.
• Drinking too much alcohol or caffeinated beverages.

Common Signs of Dehydration

One of the biggest challenges with dehydration is that symptoms can appear gradually and may be easily mistaken for other issues, such as fatigue or stress.
Here are some common warning signs that your body may not be getting enough fluids:

Persistent Thirst

Feeling thirsty is the body’s natural signal that it needs more water. However, thirst often appears after dehydration has already begun.

Dark Yellow Urine

Urine colour is one of the easiest ways to monitor hydration levels. Pale yellow urine usually indicates good hydration, while dark yellow or amber urine can indicate the body needs more fluids.

Fatigue and Low Energy

Water plays an important role in maintaining circulation and in delivering oxygen to cells. When the body is dehydrated, people may feel tired, sluggish, or less motivated.

Headaches and Dizziness

A lack of fluids can reduce blood volume and oxygen flow to the brain, which may trigger headaches or feelings of dizziness.

Dry Mouth and Skin

Dehydration often causes dryness in the mouth, lips, and skin. People may also notice less saliva production.

Muscle Cramps

Fluids help maintain the balance of electrolytes such as sodium and potassium. When hydration levels drop, muscles may cramp more easily.

Who Is Most at Risk?

While dehydration can affect anyone, certain groups are more vulnerable than others. Young children and infants are particularly at risk because their bodies lose fluids more quickly, and they may not always communicate their thirst clearly. Older adults may also experience reduced thirst signals, making it easier to become dehydrated without noticing.
People who work outdoors, exercise frequently, or spend long hours in hot environments may also lose significant amounts of fluids through sweat. Additionally, illnesses such as stomach bugs, the flu, or infections can increase fluid loss and increase the risk of dehydration.

How Much Water Do You Really Need?

There is no one-size-fits-all rule for how much water you should drink, as fluid needs can vary depending on your age, environment, activity level, and overall health.
A general guideline is around six to eight glasses of water per day, but you may need more if you exercise regularly, spend time in the heat, or are unwell.
It’s also worth remembering that hydration doesn’t only come from water. Your body gets fluids from a range of foods and drinks, including:

• Water.
• Herbal teas.
• Milk.
• Soups and broths.
• Fruits such as watermelon, oranges, and berries.
• Vegetables like cucumber, lettuce, and tomatoes.
• Smoothies made with fresh fruit or vegetables.
• Diluted fruit juices in moderation.

Simple Ways to Stay Hydrated

Maintaining healthy hydration habits does not have to be complicated. Small daily changes can make a big difference.
Some practical tips include:

• Starting your day with a glass of water before coffee or tea.
• Carrying a reusable water bottle when you leave the house.
• Drinking water regularly instead of waiting until you feel thirsty.
• Adding slices of lemon, cucumber, or mint to your water for extra flavour.
• Eating water-rich foods such as fruits and vegetables throughout the day.
• Increasing your fluid intake during exercise or in hot weather.
