The Milk-Mucus Myth Debunked
For decades, people have been told to avoid dairy when sick, believing it causes increased phlegm and congestion. This widespread belief, however, is not supported by scientific evidence. Researchers have conducted multiple studies over the years, including experiments where volunteers were intentionally infected with the common cold virus, and consistently found no statistically significant link between milk consumption and increased mucus production or congestion symptoms.
The Sensory Illusion
The lingering idea that milk makes phlegm thicker comes from a sensory perception, not a physiological reality. When milk mixes with saliva in the mouth, it can create a temporary coating that some people mistake for increased phlegm. This sensation can be more pronounced when you are already dealing with a post-nasal drip from a cold. A simple glass of water can usually clear this feeling, confirming it's a textural effect rather than a genuine increase in mucus volume.
Potential Benefits of a Milkshake When Sick
Despite the dairy misconception, a milkshake can offer some surprising benefits when you're battling a cold, provided it's consumed in moderation.
- Provides hydration: When you're sick, staying hydrated is crucial. While water is best, a milkshake can contribute to your fluid intake, especially if you have a low appetite and are struggling to drink other liquids.
- Offers much-needed calories: A cold can suppress your appetite, making it difficult to eat enough to maintain your energy. A milkshake provides a quick, easy-to-consume source of calories to help fuel your body's recovery.
- Soothes a sore throat: The cold temperature of a milkshake can have a pleasant, numbing effect on a sore or scratchy throat, offering temporary relief from discomfort.
- Delivers comfort: Sometimes, a comforting treat is the best medicine. The psychological boost of enjoying a favorite food can lift your spirits, which is a valuable, if unscientific, part of feeling better.
The Downsides: When to Avoid a Milkshake
While not directly tied to mucus, there are legitimate reasons why a milkshake might not be the best choice for everyone with a cold.
High Sugar Content
Many commercial milkshakes are loaded with sugar, which can negatively impact your immune system. High sugar intake can potentially increase inflammation in the body and may hinder your body's ability to fight off the virus. Opting for a lower-sugar or homemade version can mitigate this risk.
Potential for Stomach Upset
If your cold is accompanied by digestive issues like nausea or diarrhea, a rich, full-fat dairy product might exacerbate your symptoms. Some people, particularly those with undiagnosed lactose intolerance, may find dairy difficult to digest when their system is already under stress.
Discomfort with Congestion
For some, the thick, creamy texture of a milkshake can feel unpleasant and accentuate the sensation of having phlegm, even if it doesn't actually produce more. This can be especially bothersome if you have severe post-nasal drip.
Alternatives to a Milkshake When You Have a Cold
If a traditional milkshake doesn't sound appealing, or you want a healthier option, here are some excellent alternatives:
- Warm Lemon and Honey Tea: A classic remedy, honey helps soothe a sore throat and suppress coughs, while the warm fluid provides hydration.
- Chicken Soup or Broth: A nourishing, hydrating, and warm option that has been scientifically shown to help clear congestion.
- Fruit Smoothie (Dairy-Free): Blend frozen fruit like berries (rich in antioxidants) with non-dairy milk (like almond or oat milk) and a scoop of protein powder for a nutrient-dense, hydrating, and soothing drink.
- Popsicles or Ice Pops: These frozen treats are a great way to stay hydrated and numb a sore throat, especially for children who may not have an appetite.
- Yogurt with Probiotics: If dairy sits well with you, a serving of yogurt can provide probiotics for gut health, which supports overall immune function.

How to Make a Colder-Friendly Milkshake
If you still crave a milkshake, a homemade version can be a healthier choice. Use lower-fat or lactose-free dairy and reduce the sugar. Consider adding beneficial ingredients to boost its nutritional value.
Ingredients:
- 1 cup vanilla ice cream (or frozen yogurt)
- 1/2 cup milk or non-dairy alternative (e.g., almond or oat milk)
- 1/2 frozen banana (adds creaminess and potassium)
- A handful of spinach (for a vitamin boost, won't affect flavor)
- 1/4 tsp of ground turmeric (for its anti-inflammatory properties)
Instructions:
- Combine all ingredients in a blender.
- Blend until smooth and creamy.
- Pour into a glass and enjoy immediately. The colder temperature is soothing for a sore throat.
Conclusion: Listen to Your Body
Ultimately, deciding whether a milkshake is a good choice when you have a cold comes down to personal comfort and symptoms. The myth about dairy increasing mucus is unfounded, so you don't need to fear a milkshake for that reason. If you have a sore throat and poor appetite, the coldness and calories might provide some welcome relief. However, if you are experiencing severe congestion, a high-sugar milkshake might feel unpleasant or counterproductive. Focusing on hydration is the most important factor, so feel free to indulge in a simple, homemade milkshake if it brings you comfort. For a more wholesome approach, warm, nutrient-rich liquids and smoothies are always a safe bet. Always prioritize fluids and listen to what your body is telling you to ensure the smoothest and fastest recovery possible.
The personal comfort link
If a comforting treat helps you feel better emotionally, that can be a valuable part of recovery. This is a personal decision, and if you tolerate it well, there is no medical reason to deny yourself a small, low-sugar treat.
When symptoms persist
If your cold symptoms worsen or persist beyond 10 days, or if you develop a fever that lasts more than four days, it's wise to consult a doctor.
The bottom line
While there is no single food or drink that can cure a cold, nourishing your body and staying hydrated is key. A milkshake can be a part of that, but it's not a magical cure. Consider healthier, low-sugar alternatives if you're concerned about inflammation, and always prioritize plenty of water, rest, and doctor-approved medications.
Food and feeling good
When we're sick, our appetites can wane, but our bodies still need fuel to fight off infection. The best approach is to choose foods that are nourishing and appealing. For some, this might be a milkshake; for others, it's a warm bowl of soup. The most important thing is to consume something to keep your strength up.
Making healthy choices
When making a milkshake at home, you have full control over the ingredients. Choosing non-dairy milk and low-sugar add-ins can create a comforting and nutritious treat that won't contribute to inflammation from excessive sugar.
