The easiest thing you can do is to drink enough water. If you are busy or forget to do it, set reminders on your cellphone. There are also water applications available that remind you to drink water.

Try different water options.

You can also take advantage of different water options to avoid dehydration at night. Alkaline water is a type of water that provides further hydration and boosts your energy. Spring mountain water or purified water is also available in the market if you don’t like the taste of tap water. The point is that you can make your water type. For instance,  you can make your alkaline water.

Water-rich fruit and vegetables

Look again at your daily diet. Does it include fruits, vegetables, or water-rich food? If the answer is a disappointing “No,” try to include cucumber, cabbage, milk, apple, and other water-rich food in your diet. The list of water-rich food and drink is a long one. You need to know that you get 20% of your water intake from such food and drinks.

Healthy and sugar-free drinks such as milk and juice are also a good option. However, they are not a water replacement.



According to Healthline, alcohol tends to make you dehydrated. When you drink, your body eliminates water. Providing that you don’t drink enough water, your body tends to get dehydrated quickly. In case you drink water at night, you might wake up in the middle of the night to ease your nature. It may be hard to get back to sleep. So it would break your sleep pattern. Getting less sleep, tiredness in the morning, and less efficiency. It’s the compound effect that Darren Hardy explains in his book. So it’s better to skip alcohol or don’t drink enough water to avoid dehydration during sleep.


A glass of water in the morning

As explained, you and I lose water during sleep. So a wise choice is to first have a glass of water in the morning. Its temperature the same as the room would be better for you. The morning water will increase your energy and boost your metabolism.

Keeping one point in mind is necessary. The morning water might not work for everyone. Determine if you feel well during the day or not. If not, consult with a doctor or stop the morning water.

In case you don’t like the taste of plain water in the morning, use flavors to make it tasty. Lemon, ginger, various fruits give you a good reason to drink that glass of water in the morning. However, as we said, they should work for you well. If you feel bad after them, ask for advice from an expert.

Water before Bed

Water right before bed is another way to avoid dehydration during sleep. It holds several benefits as well:

  • Better mood
  • Cleaning body naturally
  • Better heart performance
  • Healthier skin
  • Better control of body temperature

Water before bed could be an efficient way to avoid dehydration during sleep. But you could wake up in the middle of the night to use the bathroom. In this case, you would better avoid it. However, if you keep having a good night’s sleep, it will help avoid dehydration during sleep.

The key point is to limit drink intake 1-2 hours before bed. It could raise the possibility to visit the bathroom in the middle of the night.

The amount of water depends on you. If you didn’t wake up with one cup, stick with it.

Room temperature

A hot bedroom makes it more likely that you wake up dehydrated. So health experts recommend keeping the temperature to the cooler side. Try to wear light clothes that stop overheating.

Another condition that makes you dehydrated in your room is dry air. You get to bed in a room with dry air; you are more likely to wake up thirsty. In hot areas like Las Vegas, mountain climates, and winters dry air is common. It might sap moisture from your mouth and nasal passages. Decreasing your performance or disrupting your sleep is another result of dry air. Humid air also tends to make you dehydrated.

Leaving the door open, having a plant, or using the appropriate air conditioning helps you eliminate dry and moisture bedrooms.

Can sleep affect dehydration?

You have heard that you need to drink enough water and ensure your hydration to get a good night’s sleep. But a new study says that you need to get enough sleep to ensure your hydration.

Sleep deprivation can cause many health problems in the short term and long term:

  • type 2 diabetes
  • high blood pressure
  • obesity
  • respiratory disease.


It’s quite interesting for researchers and scientists that lack of enough sleep could cause dehydration.

The new research tried to focus on the impact of not sleeping enough on hydration and kidneys.

Asher Rosinger, an assistant professor of biobehavioral health, working at Pennsylvania State University in State College, was the leader of the research.

The title of the research was: Short sleep duration is associated with inadequate hydration: cross-cultural evidence from the US and Chinese adults. It was published in Sleep Research Society.

The team tried to find a link between hydration and the duration of sleep. The participants who had slept less during the night were more likely to suffer from dehydration.

“People who slept for 6 hours or less each night regularly were 16-89% highly to suffer from dehydration than those who slept for 8 hours a night”, according to Medical News Today. The findings of the research were true for both of the population samples of the group.

In case you are getting less than 6 hours of sleep per night, it is likely that you suffer from hydration during the day.

Drinking sufficient water during the day and adding water-rich fruits and vegetables can increase hydration level and ensure your health regarding hydration.

Although the mentioned research is new, experts highlight the importance of getting enough sleep every night.

Sleep and dehydration are connected.

According to Sleep Foundation, sleep and dehydration are connected. Asher Y Rosinger, Anne-Marie Chang, and their teams studied about 20.000 adults in China and the US. It was revealed that people who got a six-hour sleep might have higher levels of dehydration than those who got an eight-hour sleep.

Now that they are connected, how can you have a good night’s sleep? Mark Manson’s Tweet here can be useful. He is one of my favorite authors, and I have just finished “Will,” the life of Will Smith by Manson.

This is a “morning routine” that people don’t talk much about. But it can be hugely useful for a good night’s sleep and a better day.

Number one is to “Eat a reasonable dinner, no caffeine or alcohol.” You can test this to see that you have a better night’s sleep when you avoid caffeine or alcohol in the evening. I have some bad dreams when I have a heavy meal. You could try and see if you feel better in the morning or not.

Number two is to “stop looking at screens around 9 PM”. Several studies say that looking at a screen late at night could disrupt your night’s sleep. So you would better find an alternative for it.

Number three is to “get into bed by 10 PM”. I can not do it at 10, but maybe 11 is fine. I am trying to stick to 11 pm sleep, and I feel better in the morning. Experts say you would better have a sleep pattern that begins and ends in a particular time frame.

Number four is to “relax, meditate, do some light reading.” It can help you to have a heavy sleep and makes you tired.

The result would be waking up fresh and ready to have a great day.

Bottom line

Since you are asleep and don’t have physical activity at night, it doesn’t mean you don’t lose water. Your body loses water through perspiration and breathing. So you need to know how to stop dehydration during sleep.

The text explained strategies to avoid getting dehydrated during sleep. You found out that room temperature, dry climate, and alcohol also make you dehydrated at night.

As explained, the ideal way is to drink enough water throughout the day.
