Do you often wake up at night from a peaceful slumber or maybe a deep sleep because you are thirsty? Do you have a sudden urge to drink a glass of water even though you had one before you came to sleep at night? Does it bother you getting up at this unearthly hour for a glass of water?  

Do you often think “Why am I thirsty at night”? Being thirsty at night could be indicative of some signal or sign that your body is trying to convey. Excessive thirst is known as ‘Polydipsia‘.

It is important to note that “always thirsty not diabetic”, but it could be one of the reasons that are causing excessive thirst in the middle of the night.

Reasons Why You Are Thirsty At Night

  1. Simply Dehydrated

Maybe the reason why you are getting up at night for a glass of water could be because you are not hydrated enough. You should drink 8-10 glasses of water daily. If your body is not getting enough fluid you might be having these episodes or urges to drink water at night. 

Water is very important for all the chemical reactions in our cells, it is a driving factor to carry all metabolic processes. Start including more glasses of water in your daily routine.

2. Room Temperature

It is very important to have a proper or ideal room temperature set when you are sleeping. If your room is too cold it might lead to frequent visits to the washroom or if it is too hot, you might be thirsty. 

Adjust the AC or fan accordingly. In summer you might need to have a cool environment while you are sleeping and a properly hydrated body.

3. Food

If you have started to eat spicy or unhealthy fried food recently that might be the reason why you are having a dry mouth and an urge to drink water at night. 

Your body produces heat when you eat such food and this leads to evaporation of sweat from your body hence demanding more water.

4. Alcohol

If you went a little heavy on the alcohol intake this could be the reason for you being thirsty at night. The hangovers are the worst. It will give you a dry throat and a sensation of a full stomach, you might feel nauseated or squeamish. 

You might want to drink water at night, even after you have fallen asleep. Cut low on the alcohol intake before going to bed. It reduces water level in your body as it is a diuretic, increasing your trips to the washroom.

5. Disease (Diabetes)

It is not necessary that you are thirsty at night because of Diabetes but it could be one of the reasons. Excessive thirst at night could be an early sign of Diabetes. The explanation is pretty simple. 

Your kidneys filter and reabsorb the extra glucose from your blood and when they are not able to cope up with the extra work, the urine is passed out with the high amount of sugar/ glucose in it, leaving you dehydrated.

6. Medication

Some medicines that are prescribed for Obsessive-Compulsive Disorders, Schizophrenia and Bipolar disorder increase thirst at night. 

It could be a reason for excessive thirst at night. You might have to talk to your doctor about this and see if your doctor could prescribe some other medicines.

7. An Early Sign Of Kidney, Heart Or Liver Condition

Thirst at night or dehydration could be an underlying symptom of organ failure. Your kidneys might be working overtime and if they are not able to function properly, it would lead to loss of water from cells and this would lead to dehydration. 

Similarly, if the heart is not able to pump blood or liver is not functioning properly, it could affect the function of kidneys. Our organs work in a harmonious and a synchronized manner, a glitch in one of them or an inability to perform their function would affect other organs as well.

8. If You Have A Cold Or Sinus Infection

When your nose is blocked or if you have a sinus infection, you might not be able to breathe through your nose and this could lead to breathing through the mouth. It causes a dry mouth and throat, thus leading to increased thirst and an urge to drink water.

9. Menopause

If you are in your late 50’s then thirst at night could be due to menopause. This is a time when your hormones are rushing through the body and there are a lot of changes occurring inside of you. 

Oestrogen level will go down, which maintains fluid level in our body, leaving you in a state of dehydration.
