Staying Hydrated in Bahrain's Heat: Water, Electrolytes & ORS
In a Bahraini summer, hydration is not a wellness trend; it is daily maintenance. Your body cools itself by sweating, and every litre of sweat carries water and salts with it. Replace the water and you feel fine. Fall behind, and headaches, tiredness and dizziness creep in.
This guide keeps it practical: how much to drink and how to tell if you are behind. It also covers when plain water is enough, and when an electrolyte drink or an oral rehydration solution is the better tool.
- Water contributes to the maintenance of normal physical and cognitive functions and to normal regulation of body temperature.
- Pale yellow urine is a simple daily check; dark, strong urine means drink more.
- Plain water covers most days; electrolytes help after long, sweaty sessions, and oral rehydration solutions are for vomiting or diarrhoea.
- Confusion, fainting or no improvement after 30 minutes of cooling and fluids needs urgent help.
Why heat changes how much you need
Sweat is your built-in cooling system. As it leaves the skin it takes heat with it, but it also takes water and electrolytes such as sodium, potassium and chloride. The hotter the day and the harder you work, the more you lose.
The NHS suggests around 6 to 8 cups or glasses of fluid a day as a general guide, and notes you may need more in a hot environment, when you are active for long periods, sweating a lot, pregnant, breastfeeding or unwell. Water, lower-fat milk and lower-sugar drinks including tea and coffee all count, and food provides some fluid too. Watery foods like cucumber, watermelon, oranges and laban are easy extras.
How to tell if you are falling behind
Thirst is a late signal, so it helps to know the others. The NHS lists these signs of dehydration in adults and children:
- feeling thirsty, with a dry mouth, lips or tongue
- headache, light-headedness or dizziness
- dark yellow, strong-smelling urine, or passing urine less often
- feeling tired, or sunken eyes
The easiest daily check is the colour of your urine: aim for a clear, pale yellow. In babies, watch for fewer wet nappies, few or no tears, a sunken soft spot on the head, and unusual drowsiness or irritability, and contact a doctor promptly.
The Bahrain angle
Summer here combines high temperatures with humidity, and in humid air sweat evaporates more slowly, so you can feel hotter and keep sweating. Moving between air-conditioned rooms and the heat outside also makes it easy to forget to drink. Plan outdoor work, training and errands for early morning or evening, and avoid the strongest sun in the middle of the day. In Ramadan, spread water across the hours between iftar and suhoor rather than drinking a large amount at once, include watery fruit and laban, and keep salty and very sweet foods moderate. People with health conditions should speak to their doctor before fasting in the heat.
Water, electrolytes or ORS: which one, when?
| Situation | Usually fits |
|---|---|
| Office day, short errands, light exercise | Plain water, spread through the day |
| Long outdoor work, a long run, a sweaty match or gym session | Water plus an electrolyte drink, or salty food with water |
| Vomiting or diarrhoea | An oral rehydration solution (ORS); ask a pharmacist which suits you or your child |
| Heat exhaustion symptoms | Cool down and drink water; the NHS notes an isotonic sports drink or rehydration powder can help replace salt lost in sweat |
A note on names: some electrolyte drink tablets carry "ORS" or "hydration" in their brand name. What matters is the label: what it is designed for, how much water to dissolve it in and who it suits. Magnesium contributes to electrolyte balance, and potassium contributes to normal muscle function, so you will often see both on electrolyte labels.

Reading an electrolyte label
- Mixing volume. One tablet in 200 ml is very different from one in 500 ml. Use the stated amount of water; making it stronger is not more effective.
- Electrolytes per serving. Look for sodium, potassium, magnesium and chloride amounts.
- Sugar and sweeteners. Some products use sugar or carbohydrate for endurance sport; others are sugar-free. A sugar-free flavoured drink mix makes water more appealing but is not an electrolyte product.
- Who it is for. Check the age range; some products are adults only.
- Extras. Caffeine or added vitamins may not suit everyone, especially in the evening or alongside other supplements.

A simple hot-day routine
- Morning: a glass of water with breakfast, before coffee.
- Commute and work: keep a refillable bottle within reach; small, regular sips beat a large amount at once.
- Training: drink before you start, sip during, and after a long or very sweaty session add electrolytes with your water.
- Evening: include watery foods at dinner and go easy on alcohol, which the NHS notes can make dehydration worse.
If you train regularly, our guides to creatine and magnesium explain how those fit alongside good hydration.
Heat exhaustion: what to do and when to get help
The NHS lists tiredness, dizziness, headache, nausea, heavy sweating with pale clammy skin, cramps, a high temperature and intense thirst as possible signs of heat exhaustion. Move the person somewhere cool, remove extra layers, give water, cool the skin with water and a fan, and stay with them. They should start to feel better within 30 minutes.
Call emergency services if they are still unwell after 30 minutes, or have hot skin that is not sweating, fast breathing, confusion, a seizure or loss of consciousness. Young children, older adults, pregnant women, people with long-term conditions and anyone taking several medicines are more vulnerable. If you have a heart or kidney condition, have been told to limit fluids, or take medication such as diuretics, ask your doctor how much and what to drink.
In Bahrain, we see hydration as a daily habit, not a product. Plain water covers most days. Electrolytes earn their place after long, sweaty hours outdoors or in training. Oral rehydration solutions are for vomiting or diarrhoea, mixed exactly as the pack directs. Sugary sports drinks are rarely needed for an office day. Watch your urine colour, drink before thirst kicks in during summer, and take the warning signs of heat exhaustion seriously.
Frequently asked questions
How much water should I drink a day in summer?
There is no single number. The NHS suggests about 6 to 8 glasses of fluid a day as a starting guide, and more in hot weather or when you sweat a lot. Use pale yellow urine as your daily check.
Do I need electrolytes every day?
Most people do not. Regular meals provide electrolytes, and water covers ordinary days. Electrolytes are most useful after long or very sweaty activity, or long hours working outdoors.
What is the difference between an electrolyte drink and an oral rehydration solution?
Oral rehydration solutions are formulated to replace fluids and salts lost through vomiting or diarrhoea; the NHS advises asking a pharmacist which one suits you or your child. Electrolyte drinks are usually designed for sport and sweat. Read the label to see which a product is.
Do tea and coffee count towards my fluids?
Yes. The NHS counts tea and coffee, along with water and lower-fat milk. On very hot days, keep plain water as your main drink and limit caffeine and very sugary drinks.
Can children use electrolyte tablets?
Only if the label says the product suits children, and at the stated dose. For a child with vomiting, diarrhoea or signs of dehydration, ask a pharmacist or doctor straight away.
