Autoimmune Symptoms May Worsen During Monsoon or Winter, Doctor Shares Potential Reasons

For many people, the arrival of the monsoon or winter means a welcome change in weather. However, for those living with autoimmune diseases, these seasonal changes can sometimes bring worsening symptoms. Aching joints, increased fatigue, skin flare-ups, or unexplained fever may become more common during these months.

Doctors often notice that patients with conditions such as rheumatoid arthritis, lupus, psoriasis, and multiple sclerosis report more frequent flares during the rainy season or winter. While the exact reasons are still being studied, experts believe that changes in weather, infections, and lifestyle habits all play a role.

According to Dr Tushar Tayal, Associate Director - Internal Medicine, CK Birla Hospital, Gurugram, autoimmune care often needs to adapt with the changing seasons. Understanding these seasonal triggers can help people manage their condition more effectively.

Why Do Seasonal Changes Affect Autoimmune Diseases?

Dr Tayal explains that for millions of people living with autoimmune diseases, changing seasons are more than just a temperature change. As monsoon clouds arrive or winter temperatures fall, doctors often see patients returning with flared joints, worsening skin symptoms, severe fatigue, or unexplained fever.

The reasons are not entirely clear, but several factors appear to contribute.

Can Changes In Air Pressure Increase Joint Pain?

According to a study published in The American Journal of Medicine, one of the possible reasons for increased flares is barometric pressure, which refers to the pressure of the atmosphere around us.

Before rainfall, atmospheric pressure often drops. Some people with rheumatoid arthritis or lupus report increased joint pain and stiffness during these periods.

Scientific studies have produced mixed results, and researchers have not yet confirmed exactly how this happens. However, one theory is that changes in air pressure may slightly affect the tissues surrounding joints, placing additional pressure on already sensitive nerve endings and increasing discomfort.

Although not everyone experiences this, many patients notice that their joints become stiffer before or during rainy weather.

Effect of Humidity on Autoimmune Skin Conditions

Humidity can also influence autoimmune diseases, particularly those affecting the skin.

During the monsoon, damp conditions encourage the growth of fungi and bacteria. Increased sweating and moisture on the skin may increase the risk of skin infections.

According to Dr Tayal, in people with immune-mediated skin conditions such as psoriasis or eczema, infections, sweating and microbial growth may aggravate symptoms or slow the healing of existing skin lesions.

However, humidity does not affect everyone in the same way. Some people may notice improvement, while others experience worsening symptoms.

Why Is Winter Difficult For People With Psoriasis Or Eczema?

Winter brings a different challenge.

According to a study published in the journal Experimental Dermatology, cold air contains less moisture, and indoor heating can make the air even drier. This removes natural moisture from the skin, weakening its protective barrier.

As a result, people with psoriasis or eczema may experience:

• Dry skin
• Cracking
• Itching
• Redness
• Increased irritation

Without proper skin care, these symptoms may become more severe during the colder months.
Using moisturisers regularly can help protect the skin barrier and reduce irritation.

Can Infections Trigger Autoimmune Flares?

Infections are one of the most common triggers for autoimmune flare-ups.

During the monsoon, illnesses such as viral fever, dengue, flu, stomach infections, and bacterial infections become more common.

When the body fights an infection, the immune system becomes more active. According to a study published in the Journal of Autoimmunity, increased immune activity in people with autoimmune diseases may also trigger a flare of the underlying condition.

Winter also brings a rise in respiratory infections, including colds, influenza, and other viral illnesses.

Although infections cannot always be avoided, reducing exposure to illness can help lower the risk of autoimmune flare-ups.

Does Vitamin D Play A Role?

Vitamin D is important for bone health and also helps regulate the immune system.

During winter, people often spend less time outdoors and receive less sunlight, which may reduce vitamin D production in the skin.

Dr Tayal notes that lower vitamin D levels may affect autoimmune conditions, although research is still ongoing.

Patients at risk of vitamin D deficiency should discuss testing and supplementation with their healthcare provider if necessary.

Does Reduced Physical Activity Make Symptoms Worse?

Lifestyle changes during different seasons can also affect autoimmune diseases.

Cold weather often discourages outdoor activity. Spending more time indoors may lead to:

• Joint stiffness
• Muscle weakness
• Reduced flexibility
• Increased fatigue

Similarly, heavy rain during the monsoon may interrupt walking, exercise routines, or other physical activities.

A 20-year systematic review published in the Journal of Sport and Health Science shows that regular movement helps keep joints flexible and muscles strong. Even gentle stretching, indoor exercise, or yoga may help reduce stiffness and improve mobility.

Can Sleep And Diet Also Be Affected?

Yes, seasonal changes often disrupt everyday routines.

The monsoon may affect meal timings, physical activity, and sleep quality, while shorter winter days can alter daily habits.

Poor sleep, unhealthy eating patterns, and increased stress may not directly cause autoimmune diseases, but they can influence overall health and may make symptoms harder to control.

Maintaining regular routines throughout the year can help support better disease management.

How Can You Reduce The Risk Of Seasonal Flare-Ups?

Although seasonal changes cannot be avoided, there are practical steps that may reduce the likelihood of flare-ups. Dr Tayal advises patients to:

• Continue taking prescribed medications without interruption.
• Stay physically active according to their ability.
• Keep the skin well moisturised during winter.
• Practise good hand hygiene to reduce the risk of infections.
• Discuss periodic vitamin D assessment with their doctor if appropriate.
• Stay up to date with recommended vaccinations after consulting their healthcare provider.
• Seek medical advice promptly if symptoms worsen instead of waiting for them to settle on their own.

These simple measures can help maintain better disease control throughout the year.

When To See a Doctor?

People with autoimmune diseases should seek medical advice if they notice:

• Increasing joint pain or swelling
• Persistent fever
• Worsening skin rashes
• New weakness or numbness
• Severe fatigue that interferes with daily activities
• Symptoms that do not improve with regular treatment

Early treatment of a flare may prevent complications and reduce long-term damage.

Final Word

Many people with autoimmune diseases notice that their symptoms become worse during the monsoon or winter. Seasonal flare-ups are not a reason to panic, but they are a reminder that autoimmune care often needs to adapt as the weather changes. While flare-ups cannot always be prevented, understanding the triggers and taking simple precautions can help people with autoimmune diseases stay healthier and maintain a better quality of life throughout the year.
