Our bodies are made up of 60% water; this makes drinking water throughout the day important for our health so that we can function properly*. Taking in the right amount of water can be tricky though, especially when on the go throughout the day.

Keep on reading to find out the benefits of drinking water on the go and how it can help to make you feel refreshed throughout the day.

Preventing dehydration

When on the go remembering to drink plenty of water and to stay hydrated isn’t easy. You will often be concentrating on other things and rushing about here and there, this can leave your body feeling dehydrated. Becoming severely dehydrated can have a major effect on your health. Even minor dehydration can affect the way your body functions.

Here are just a few effects that not drinking throughout the day and becoming dehydrated can have on your body [1] [2]:

  • Thirsty – Your mouth will become dry and you will become thirsty, this is one of the warning signs you are becoming dehydrated.
  • Fatigue – You will begin to feel tired and you will not be able to function at your usual rate. This can affect your performance when at work or even when performing the simplest of tasks.
  • Confusion – One sign that you are dehydrated is that you are becoming confused and dizzy.
  • Muscle cramps – Another effect dehydration could have on your body is that muscles may begin to cramp and ache. This symptom is usually present when undertaking strenuous physical activity such as sports.
  • Headaches – When your body is not hydrated properly your brain will shrink slightly. This shrinking can cause a mild, to severe headache.

Improving concentration

One of the benefits of drinking water on the go is that it will help maintain your concentration levels. Water gives the brain electrical energy, which is necessary for all brain functions, including memory recall and concentration. This means

staying hydrated will help you to boost your brain power throughout the day [3].

If you are not drinking enough water, you will start to lose focus easily and will not be able to concentrate. This is because brain cells need 2x more amounts of energy than any other cell in the body. Water is one of the best ways to provide your cells with the energy they need.

It is also advisable that you drink water throughout the day rather than in bulk. This is because your brain has no way of storing water; for this reason, drinking water in bulk will not keep it hydrated throughout the day. Instead you should drink a few sips of water every hour to keep topping up the levels of water in your body and brain. Doing this is a much more effective way of staying hydrated and will help you improve your levels of concentration. This being said, drinking a few sips of water every hour can be very difficult when on the go or travelling.

Maintaining body temperature

The human body has the ability to keep its own body temperature within certain boundaries, even when the conditions outside of the body are very hot or cold. This process is called thermoregulation and water is an important part of it [4].

When the temperature outside is very hot, your body will start to expel water through sweat. The evaporation of sweat causes a loss of calories in the form of heat, this release of energy decreases your internal body temperature.

Once sweating has begun it’s very important to rehydrate your body to replace the water that has been lost. If you do not do this, dehydration symptoms could begin to occur. This makes drinking water throughout the day especially important when you are out and about in the heat.
