How to Feed, Hydrate, and Heal Yourself When You’re Sick

When you come down with something, whether it’s a cold, flu, or another bug, your body quickly shifts into battle mode. It is normal for your appetite to fade, your energy to dip, and you might not even want to think about food.

And, that’s actually a smart immune system doing its job!

Your immune system is diverting its resources away from digestion and toward defense… ramping up white blood cells, fighting off pathogens, and raising your body temperature to make life harder for those invading germs.

What is important to remember is the quality of what you give your body during illness can make a huge difference in how efficiently you recover. You don’t need huge portions or frequent snacks to give your body the energy it needs to fight off an infection. You just need the right nutrients to support your body’s natural repair system.

Let’s walk through some easy tips on how to help your body efficiently ward off an invasion so that you can quickly get back to enjoying this beautiful time of year!

1. Antioxidants: Your Body’s First Line of Defense

Why Antioxidants Matter

Every time your immune system fights off an illness, it naturally creates inflammation and along with that comes oxidative stress. That’s where antioxidants come in.

Antioxidants neutralize the free radicals that build up during an illness. They are essentially a robust cleanup crew, helping reduce cellular stress so your immune system can focus on the real work. The more helpers in your clean up crew, the better (and faster) you are going to feel.

Top Antioxidant Foods for Recovery

• Broccoli: Contains sulforaphane, a compound shown to support immune resilience.
• Blueberries: Loaded with anthocyanins, which protect immune cells from oxidative damage.
• Citrus fruits (oranges, grapefruit, lemon): High in vitamin C, which boosts white blood cell activity.
• Ginger & turmeric (supplement form is helpful too): Contains anti-inflammatory compounds (gingerols and curcumin) that calm the immune response.
• Carrots & sweet potatoes: Packed with beta-carotene, which converts to vitamin A, and is essential for mucosal and respiratory defense.

Tip: The more colorful your plate, the stronger your immune support.

Tip: One of the BEST ways to consume these different foods, especially when you’re not feeling well is by making (or better yet, have someone make it for you), a hearty soup, loaded with a wide variety of colorful veggies. Throwing in a dash of turmeric to your chicken noodle soup is one easy way to add a simple, yet powerful immune boost.

Pro Tip: When you are feeling well, before you even get sick this season, consider making a double batch of your favorite vegetable and protein soup and freeze it for when that dreaded time comes and you need a healthy, yummy, meal.

2. Hydration: The Unsung Hero of Recovery

Why Hydration Is Crucial

When you’re sick, your body loses fluids faster, especially if you have a fever, cough, or congestion. Water helps keep mucus thin, regulates temperature, and carries nutrients where they’re needed most.

Hydration Goals

• Drink at least half your body weight (in pounds) in ounces of water per day, and even more if you have a fever or are sweating.
• Add electrolytes (like sodium, potassium, and magnesium) to help retain fluid. Electrolyte powders, a squeeze of lemon, or a pinch of sea salt in water all work well.

Without electrolytes, your body is not able to efficiently absorb the water you are drinking which results in your body excreting the much needed water as waste.

Dehydration slows recovery because it quite literally thickens your blood… meaning slower circulation, slower detoxification, and slower healing.

Hydration Options When Sick

• Warm lemon water with honey
• Homemade broth (bonus points for bone broth… it adds minerals and amino acids)
• Herbal teas

3. Protein: Your Repair Material

Why Adequate Protein Is Important

During illness, your body breaks down more protein to make immune cells, enzymes, and antibodies. That’s why adequate protein is critical when you’re fighting something off.

We have no protein bank to pull from in times of illness. Unlike fats and carbs, protein has no storage. So, this is why it is so important to eat enough protein in times of illness.

If you under-eat protein, your immune system has to work harder with fewer building blocks, resulting in a longer recovery.

Gentle, Protein-Rich Foods for Sick Days

• Eggs: easy to digest and high in immune-supporting amino acids like cysteine
• Chicken or turkey: classic, soothing, and rich in zinc and B vitamins
• Collagen or bone broth: easy on the stomach, helps repair gut and tissue lining
• Yogurt: adds probiotics for gut support and protein (try “Skyr” yogurt, it has double the protein)

4. Rest and Relaxation: The Medicine We Forget

The Importance of Rest

It’s easy to underestimate rest, but sleep is when your immune system does its best work.

During deep sleep, your body releases growth hormone and cytokines that regulate inflammation and coordinate your immune defenses. Even short naps or simply lying quietly can lower cortisol (your stress hormone), which allows your immune system to function more effectively.

Bonus Tip: Prioritize watching comedies instead of intense dramas when you are trying to lay low. Laughter and lightheartedness will lower stress levels and also help you heal faster.

5. The Lymph System: Your Body’s Drainage Roadways

How the Lymph System Supports Healing

This is a piece most people overlook or simply just don’t know enough about.

Your lymph is like your body’s internal cleaning crew. It carries away waste, cellular debris, and pathogens so your immune system can focus on defense. When you’re fighting an infection, that lymph network is working overtime.

But unlike your blood, your lymph doesn’t have a pump. It relies on your movement, breathing, and hydration to keep flowing. If lymph flow gets sluggish, toxins and waste can linger longer, leaving you feeling sluggish, achy, or slow to recover.

Ways to Support Lymph Flow While You Heal

1. Move a little. Even light stretching or walking helps move lymph through muscle contraction.
2. Deep belly breathing. The diaphragm acts like a pump that pushes lymph upward through the chest. We have a major lymph roadway system in our chest cavity that helps drain the congestion from our head.
3. Stay hydrated. Lymph is mostly water; dehydration thickens it and slows drainage.
4. Gentle massage. Light circular motions on the neck, armpits, or behind the knees can stimulate lymphatic flow. There are many Youtube videos from practitioners showing how you can do some easy, self massage techniques to aid in drainage at home.
5. Contrast showers. Alternating warm and cool water can encourage circulation and lymph movement.

Bonus: By helping to aid your lymphatic system, you can help prevent secondary bacterial infections from setting in like sinus or ear infections. So, if you are prone to secondary infections, this would be a great tool to implement as soon as you start feeling congested!

When you help your lymph system, you’re giving your immune system a cleaner battlefield to work on.

Supplements to Support Your Immune System

Top Immune-Supportive Supplements

While some of the best things we can do for our immune system is to follow the simple suggestions above, we can also “supplement” our immune defenses with some extra players on board.  There are MANY immune supportive supplements on the market nowadays, and most of those are great and helpful!

We chose just a handful of our favorite ones to spotlight in no particular order.

Vitamin D:

This is so crucial for supporting a well functioning immune system. If you’re not already taking it as a daily supplement, then consider starting especially to help combat the dreaded cold and flu season. Studies have shown that people with higher Vitamin D levels have lower risk of getting colds.

N-acetyl cysteine (NAC):

This is an amino acid and a much needed one. NAC is a precursor to glutathione, our most powerful antioxidant! Our need for antioxidants significantly increases during a time of illness so repleting our stash is helpful for a faster recovery time.

Bonus: NAC is also a mucolytic, meaning it helps to thin our secretions. This can also be helpful in preventing secondary infections like sinus and ear infections from taking hold.

Colloidal Silver:

Both throat and nasal sprays are on the market and both are great to have on hand. We tend to use this more often as a preventative tool. It can kill viruses, especially in the early stages of illness. So, if you’ve been exposed to a sick coworker or family member then using this to spray on your mucous membranes (our first line of defense) is a great way to help prevent any infection from setting in.

Lysine:

Also an amino acid, Lysine helps block viral replication and therefore may slow down a virus from spreading. Best part… It is quite cheap!

Vitamin C:

The ultimate legendary team player. Vitamin C helps produce and activate immune cells, calms inflammation caused by immune system activation, and helps reduce severity in symptoms.

Tip: “Liposimal” Vitamin C is best absorbed. Typically a little more expensive, but worth it!

Quercetin:

 A great additional antioxidant to consider when things get sticky. Quercetin is a major antioxidant but also has anti-viral properties. It has been shown to help shorten the length of an illness. Score!

Zinc:

So helpful for managing an illness. Similar to Vitamin C, it plays a huge role in development of all the different immune cells that are needed to fight an infection. It also helps balance the pro-inflammatory and anti-inflammatory immune responses… both of which we need.

Nasal Sprays:

We always have a variety of nasal sprays on hand. Even using a simple saline nasal spray can not only provide relief from that pesky congestion but it helps to aid your body in thinning the mucous. These are great for comfort but also another tool to help prevent secondary infections. There are many other nasal sprays on the market that have various anti-viral ingredients included but a deep dive on those will need to be saved for another day.

The Takeaway

All in all, the takeaway message is when you’re sick, your body is working harder than you probably realize. It’s rebuilding, defending, and detoxing. And, frankly… that hard work requires resources.

Eat colorful, whole foods. Stay hydrated. Prioritize protein, rest, and gentle movement and you will be back in fighting form in no time.
