Why Am I So Thirsty? 3 Reasons You’re Always Super Thirsty

Feeling thirsty every now and then is normal. We’ve all been there after a good workout or on a busy work day when hydration just slipped our minds. But if you’re regularly asking yourself ‘why am I so thirsty’, chances are your body is trying to tell you something important. But what exactly? In this article, we explain all of the different reasons why you might be feeling thirsty. We’ll also tell you how best to quench your thirst So, keep reading to find out!

Why am I so thirsty?

Excessive thirst is oftentimes the result of dehydration. Not hydrating properly during exercise and failing to boost your water intake during hot summer days are the most common explanations for that super-thirsty feeling. But eating spicy food or going overboard with coffee can lead to the same outcome: endless thirst you can’t wait to quench. 

Here are the nine most common reasons why you’re always feeling thirsty.

1. Dehydration

If you’re asking yourself ‘why am I so thirsty?’, the answer is that you're probably dehydrated. Dehydration is when you don’t have enough fluid in your body to properly function. Around half of our bodies are made up of water and we need to maintain our natural water balance in order to stay healthy.

We lose more water than any other essential nutrient in our bodies. On average, we can lose about four and a half pints of water a day. So, if you’re thinking ‘why am I so thirsty all of a sudden?’, thirst is our body’s early alert that we are already dehydrated. Losing just 1% of our body water will make you feel thirsty. This also means that your memory function, attention-span, concentration and reaction time could decrease by about 10%. These are just a few of the most common side effects of dehydration . Check out our handy article to discover more.

You can easily tell how dehydrated you are by checking the colour of your pee. Clear or pale-yellow pee means your water balance is okay, but anything darker suggests dehydration. The darker your pee, the more dehydrated you are.

Whenever you start wondering why you’re always thirsty, remember that we need to replace all the fluid we naturally lose throughout the day and night by regularly topping up with water. Otherwise, we can easily get dehydrated .

2. Exercise

When we exercise our muscles generate heat. To try to keep our temperature down, our bodies get rid of that heat by sweating. Sweating uses up lots of our bodies’ water.

3. Hot weather

The same principle applies in hot weather - even when we aren’t exercising. Feeling really thirsty in the summer is a sign we need to top up our water intake. Our bodies are constantly perspiring, even when we don’t notice it. In hot weather we’ll be passively losing more fluid than normal because our body temperature will be higher than normal.

How can I stop feeling thirsty?

As our bodies are constantly losing water, it’s important to keep topping up.

Pure water is always best to drink

Sip water little and often throughout the day. Make sure to check out if you should drink warm or cold water with our article.

Low-fat milk, low-sugar or sugar-free drinks are also good

Avoid any drinks that contain lots of added sugar, such as fizzy drinks and squashes.

Limit fruit juices and smoothies

These contain lots of free sugar so you should stick to just a small glass a day. Here are our top tips to beat those sugar cravings successfully.

Limit caffeine intake

Beware of drinking lots of tea or coffee as they could make you pee more and therefore, more dehydrated.

Is feeling thirsty dangerous?

Dehydration can have a bad effect on us . Just two hours of dehydration may lead to cognitive decline and physical impairment. Becoming more dehydrated may make it hard for you to focus or unable to navigate tricky tasks. Your hand-eye coordination could also suffer and you’re likely to be feeling tired, lethargic or lightheaded. Dehydration could also give you a headache, make you feel irritable or even aggressive.

Drinking water may have an immediate effect on all of these symptoms. Keeping a glass or bottle of water to hand will help you to stop feeling thirsty in the first place and keep dehydration at bay.

We’ve looked at why you might be feeling thirsty and how you can easily prevent dehydration.
