Understanding how to stay hydrated is essential for every traveller, especially when flying or switching climates.
TL:DR
Travelling, flying and clean eating all increase your hydration needs. I use RE:POWR electrolytes daily because they support energy, muscle function and cognitive clarity, especially on long travel days. Most people only need one serving per day, and the formula is clean, unprocessed and made with unrefined Oryx Desert Salt from the Kalahari. In South Africa the same product is sold under the brand name REVIVE. This guide explains how electrolytes support travel, fitness, hydration and low carbohydrate lifestyles, and how I use them safely in my real food routine.

Let’s Talk About How To Stay Hydrated for Travel and Everyday Life
Travel challenges the body in ways we often overlook. Dry cabin air, long airport walks, disrupted eating routines and changing climates can all affect hydration. I learned this through years of flying, and more recently through the clean eating, low carbohydrate and food sequencing habits I adopted during my recovery from stage 3 colon cancer earlier this year. I now follow a real food approach with no junk food, no processed or ultra processed foods, no seed oils and a focus on whole ingredients. Once I understood how hydration and electrolytes support this kind of lifestyle, my energy levels changed and my travel and office days became easier.
Staying hydrated when flying is especially challenging because cabin air and airport environments make fluid loss happen faster than most travellers expect.
This is why I use electrolytes daily and why my partnership with RE:POWR Electrolytes feels natural. I was a paying customer long before any collaboration. I already buy their flavoured sachets in the mixed flavour packs of 40, for daily variety of the eight different flavours. Because they fit my real food principles, and they have kindly supplied their branded bottle and raw unflavoured sachets to include in this travel hydration guide and product review.
Why Knowing How to Stay Hydrated Is More Than Drinking Water
Hydration depends on electrolytes such as sodium, potassium, calcium and magnesium. These minerals support energy, muscle function, cognitive performance, digestion and sleep. When levels drop, you feel it. Common signs include headaches, fatigue, poor concentration, low mood, muscle cramps, irritability, brain fog and weakness during exercise.
Travel, high humidity countries, heat, exercise and certain diets can increase electrolyte loss. Many people mistake electrolyte imbalance for jet lag or general travel exhaustion. For example if you were visiting Bohol in the Philippines, where the average daily temperature is around 33 celsius with 85% humidity, you can expect to lose a lot of fluids which need replacing. Such as the tropical region around the Chocolate Hills in Bohol.
Why Staying Hydrated Benefits Travellers
Flights are incredibly dehydrating. Aircraft cabins usually sit below twenty percent humidity, which is lower than many deserts. You lose water through breathing alone. Combine that with airport movement, caffeine, alcohol consumption, time zone changes and irregular meal times, and hydration levels shift quickly.
Supporting electrolytes can help improve comfort during long flights, support cognitive clarity, reduce post flight grogginess, stabilise muscle function during long walking days, support sleep after landing and make jet lag easier to manage. This is helpful for tourists, solo travellers, business passengers, airline crew and pilots.
These are the reasons most travel hydration tips now highlight the importance of electrolytes for longer journeys and active sightseeing days.
Hydration for Gym Users and Active Lifestyles
Anyone who exercises benefits from stable electrolyte levels. Sweat removes sodium and potassium, which affects muscle contractions and recovery. If you experience cramps or dips in performance, it can be linked to electrolyte loss.
During city breaks or adventure travel, walking, activities and heat can increase this loss without you noticing.
This is also why staying hydrated on long flights supports muscle recovery, especially if you train regularly or are walking long distances during your trips.
Keto, Low Carb and Real Food Lifestyles
My current diet is low to ultra low in carbohydrates, high in clean real proteins and medium high in healthy fats such as avocado, coconut oil, real salted butter, avocado oil, tallow, ghee and extra virgin olive oil. I avoid anything marketed as high protein because those products are usually filled with sugars, emulsifiers and preservatives that I do not consume. It is focused on whole foods without processed ingredients or seed oils. When you lower carbohydrates and cut out processed foods, you remove the hidden sodium most people consume daily. You also lose more water when burning stored glycogen.
This is why many people feel tired when switching to clean eating or low carb. Electrolytes help maintain balance, support appetite regulation and stabilise energy. This is also why I originally purchased RE:POWR.

What RE:POWR Is Scientifically Formulated For
The packaging states that RE:POWR electrolytes support exercise, muscle support, cognitive function, long flights, big nights and recovery. These categories cover travel, fitness and active daily routines.
Why I Use RE:POWR Electrolytes
RE:POWR uses Oryx Desert Salt sourced from the Kalahari in South Africa. It is unrefined, sun dried and free from additives. The natural flavouring is made from spray dried fruit vapour and the formula is sweetened with Stevia instead of sugar. RE:POWR in the United Kingdom uses the same ingredients as the REVIVE electrolytes sold in South Africa. Their sachets dissolve quickly and are convenient for travel.
I find this especially useful for how to stay hydrated when looking for clean hydration for travel because the formula supports both flying comfort and active days on the ground.
Why I Use This Electrolyte Brand
What I personally like includes naturally flavoured blends made from spray dried fruit vapour, clean ingredients, no UPFs, no seed oils, easy mixing, suitability for airport travel when carried unopened and mixed only after security, and support for hydration without processed ingredients.
I was already a paying customer before any collaboration, and RE:POWR have kindly supplied their raw unflavoured sachets and their 1L car/gym drink holder compatible sized bottle for me to include in this review. I’ll continue to purchase the flavoured sachets for myself.
My Thoughts on the Flavour Options
All of the flavours I find enjoyable and easy to drink. They are not too sweet or too salty when mixed with 750ml of water or more. I personally stick to 750ml per sachet and pace it throughout the day or 900ml and I consume it faster. RE:POWR offers all eight flavours individually in boxes of 30 sachets, and they also offer variety boxes in either 20 or 40 sachets. Raspberry and Lemon Lime are additionally available as their own 30 sachet boxes. The full RE:POWR range is:
Variety Mix 1 Flavours:
Raspberry
Lemon Lime
Watermelon
Peach
Variety Mix 2 Flavours:
Apple
Blackcurrant
Blood Orange
Cucumber Mint
Raw Option:
Unflavoured
Custom:
Build a 30’s Box
The brand sent me a complimentary box of their Raw option, I hadn’t considered ordering it previously as I presumed that it would just taste either bland or salty. However, neither presumptions were the case. My honest experience, although its subjective of course is that the Raw version will taste like anything you have previously consumed, when i tried it, I had just had a roast dinner, so it tasted like roast meats and vegetables, the following day I had it after fresh blueberries and the Raw unflavoured sachet, kind of took notes of those too. Its certainly very different to others I had tried in the past. The Raw Unflavoured option is certainly worth exploring.
How to Stay Hydrated Using Electrolytes When Travelling
Electrolyte needs vary depending on your diet, activity level and destination. Most people following a clean eating or low carb lifestyle only need one sachet per day. This supports hydration without excess sodium intake.
Official RE:POWR guidance from the packaging
“We recommend 1 serving per day for low carb diets, intermittent fasting or moderate exercise and 1 serving per 2 hours of intense exercise. Do not consume more than 2 servings per day for adults. Daily maximum may be relaxed for longer endurance events.”
My practical tips based on this guidance
Before your flight
Use your daily serving at any point that suits your schedule. You do not need a serving specifically before the flight.
During your flight
Most people only need plain water. Electrolytes are optional for long haul flights or if you are fasting or following low carb that day. Do not exceed your daily serving.
After landing
If you have not taken your daily serving yet, you can mix it here to support hydration and sleep adjustment.
Hot and humid destinations
Heat increases sweat loss, but this does not mean taking multiple sachets. For normal sightseeing or light activity, one serving per day is enough. Only intense exercise in tropical heat requires more frequent use.
Who Benefits Most from Electrolytes
Electrolytes support travellers, frequent flyers, airline crew, gym users, hikers, clean eating lifestyles, keto and low carb diets, people prone to dehydration headaches and anyone with a busy or active routine. They are a simple and effective way to improve travel comfort and everyday wellbeing.
These approaches work well for any traveller looking for practical electrolytes for travel that fit into both your travel gear easily or for a clean eating or low carbohydrate lifestyle. I have previously reviewed Stubble&Co’s Tech Bag which these sachets easily fit into as shown.
Geographic Information for Global Readers
RE:POWR Daily Electrolytes in the United Kingdom are the same formula sold as REVIVE in South Africa, so readers in both regions can expect identical ingredients and hydration support. Further guidance is available on the authoritative link below.
