Power Up Your Immune System: How Drinking Water Can Help Combat the Common Cold


Does Drinking Water Help Fight a Cold?

It’s common knowledge that staying hydrated is essential for maintaining good health. But can drinking water actually help fight off a cold? In this article, we will explore the connection between drinking water and the common cold, and determine whether it truly helps to combat the symptoms.

Understanding the Common Cold

The common cold is a viral infection of the upper respiratory tract. It is caused by a group of viruses known as rhinoviruses, which thrive in the nasal passages and throat. While there are more than 200 different types of viruses that can cause a cold, rhinoviruses are the most common culprit.

According to the Centers for Disease Control and Prevention (CDC), adults can expect to catch a cold an average of 2-3 times a year, while children can contract up to 6-8 colds annually. Unfortunately, there is no cure for the common cold, and treatment primarily focuses on managing the symptoms until the infection passes.

The Role of Water in Fighting a Cold

Drinking water is crucial for a variety of bodily functions, including the immune system. Our body is made up of 60% water, and when we are dehydrated, our immune system doesn’t function as efficiently in fighting off infections.

So, when it comes to fighting a cold, staying hydrated is essential. Drinking plenty of water can help thin out mucus secretions, making it easier to expel them from the body. It can also prevent dehydration, which can worsen the symptoms of a cold, such as a sore throat or headache.

Other Ways Water Can Help with a Cold

Aside from keeping you hydrated, water can also aid in relieving other symptoms of a cold. For example, drinking warm water with lemon and honey can soothe a sore throat, and the steam from hot water can help clear a congested nose.

Besides drinking water, it is also essential to maintain a moist environment to help alleviate a cough. This is because dry air can irritate the throat, causing a cough. So, try using a humidifier or taking a steamy shower to provide relief.

How Much Water Should You Drink When You Have a Cold?

When it comes to staying hydrated while fighting a cold, the general rule of thumb is to drink enough water so that your urine is light yellow or clear. This typically equates to 8-10 glasses of water per day for adults. However, it is always best to listen to your body and drink enough water to prevent dehydration. If you feel thirsty, then you are already dehydrated.

Additionally, it’s important to keep in mind that drinking liquids that contain sugar, caffeine, or alcohol can actually dehydrate you. So, it’s best to stick to plain water or herbal teas when you have a cold.

Can Drinking Water Help Prevent a Cold?

While staying hydrated can help alleviate cold symptoms, can it actually help prevent you from catching a cold in the first place? Unfortunately, there’s not a straightforward answer to this question. Some studies have shown that drinking water can help boost the body’s immune response, while others have found no evidence to support this claim.

However, one thing is for sure – staying hydrated is always beneficial for your overall health and can contribute to a stronger immune system. So, even if it doesn’t prevent a cold, drinking enough water throughout the day is still essential.


In conclusion, while drinking water may not directly cure a cold, it certainly plays a significant role in helping alleviate the symptoms and keeping your body hydrated. So, the next time you feel under the weather, make sure to keep a glass of water close by and drink up!
