What is Lupus and How Does It Affect the Body?

Lupus is an autoimmune disease, which means that the body’s immune system, which usually fights infections, begins attacking healthy cells and tissues by mistake. This can cause inflammation, pain, and damage to various parts of the body, such as the skin, joints, heart, and kidneys.

There are different types of lupus, but the most common is called Systemic Lupus Erythematosus (SLE). People with SLE experience a variety of symptoms that can affect their everyday life, and one of those symptoms is problems with regulating body temperature. This is where the issue of overheating comes in. People with lupus often feel too hot, sweat excessively, or experience hot flashes even when the temperature is normal.

Why Does Lupus Cause Overheating?

There are several reasons why lupus can make people feel hot, sweaty, or sensitive to heat. The main cause is related to how lupus affects the body’s ability to regulate temperature. Let’s take a closer look at some of the main reasons why this happens:

1. High Nitric Oxide Levels
   When you have lupus, your body can produce high levels of a chemical called nitric oxide. This is a natural substance that helps your blood vessels widen and allows more blood to flow to the surface of your skin. While this is useful in certain situations, high levels of nitric oxide in lupus patients can cause the blood vessels in the skin to expand too much, making you feel hot and sweaty.
2. Flare-Ups and Inflammation
   During a lupus flare-up, when the disease is more active, inflammation can increase in the body. This inflammation can affect the way your body handles temperature, making you feel overheated. When your lupus is more active, you may also experience low-grade fevers, which are another sign of overheating.
3. Sun Sensitivity (Photosensitivity)
   Many people with lupus have a condition called photosensitivity, meaning they are sensitive to sunlight. Even brief exposure to the sun can cause their skin to turn red, and they may feel hot and uncomfortable. This sensitivity can make it hard to spend time outdoors without feeling overheated.
4. Other Health Conditions
   In addition to lupus, other health conditions that often go hand-in-hand with it can also contribute to overheating. For example, people with lupus might also have thyroid problems, diabetes, or fibromyalgia, all of which can make heat intolerance worse.

What Other Conditions Can Cause Overheating in Lupus Patients?

Lupus does not act alone in causing overheating. There are several other conditions and factors that can make someone with lupus even more sensitive to heat:

1. Thyroid Disorders
   Having an overactive thyroid (hyperthyroidism) can make people feel very hot, even in cooler environments. The thyroid helps regulate body temperature, and when it’s not working properly, it can cause overheating.
2. Diabetes
   People with diabetes can experience nerve damage and problems with their sweat glands, making it harder for their body to cool down. This can cause overheating, especially when combined with lupus.
3. Hormonal Changes
   For women, hormonal changes like those experienced during menstruation, pregnancy, or menopause can lead to hot flashes and sweating. These changes in hormone levels can make overheating worse in people who already have lupus.
4. Medications
   Some medications that are used to treat high blood pressure, allergies, or even depression can cause side effects like hot flashes and excessive sweating. These can make it even harder for someone with lupus to stay cool.
5. Stress and Anxiety
   When you are stressed or anxious, your body can react by overheating. Stress and anxiety trigger the release of hormones that increase heart rate and body temperature, leading to sweating and hot flashes.

Symptoms of Overheating in Lupus Patients

If you have lupus, you might experience a variety of symptoms related to overheating. Here are some of the common signs:

• Excessive Sweating
  Even when you’re not exerting yourself, you may sweat a lot. This can be uncomfortable and may happen without warning.
• Hot Flashes
  You may suddenly feel a rush of heat that makes your face and body feel hot. This often happens during the day but can also occur at night, causing night sweats.
• Flushed Skin
  Your skin may become red or warm to the touch, especially if you’re exposed to sunlight or heat.
• Low-Grade Fever
  Sometimes, lupus causes fevers that are mild but still make you feel overheated and uncomfortable.
• Sensitivity to Sunlight
  If you have lupus, sunlight can make you feel much hotter than it should. You might notice your skin gets redder and you feel uncomfortable even in mild sun.

Beyond the basic methods for staying cool, there are other strategies you can implement into your daily routine to reduce overheating, especially if you live in hot climates or experience frequent flare-ups. Here are some additional practical steps:

Use Air Conditioning and Fans

During hot weather, air conditioning can make a significant difference in keeping your home or workspace cool. If air conditioning is unavailable, fans are a more affordable alternative. Use them to circulate air and create a comfortable atmosphere. Ceiling fans, standing fans, or desk fans can help lower the ambient temperature and provide relief from overheating. If possible, keep the windows open in the early morning or evening when the air is cooler to encourage airflow.

Take Cool Naps

If you feel yourself becoming overheated or fatigued, consider resting in a cool environment. A short nap in a cool room can help your body regulate its temperature and allow you to recover from the heat. Using cooling products, like an ice pack or chilled towel, during a nap can provide additional relief.

Create a Cool Environment in Your Bedroom

At night, try to keep your bedroom as cool as possible. Use light bedding made from breathable fabrics such as cotton. If you have access to air conditioning, make sure it’s running before bedtime. Alternatively, you can place a bowl of ice or a cooling fan near your bed to lower the room temperature. This is particularly helpful if you suffer from night sweats, which are common in lupus patients during flare-ups.

Eat Cooling Foods

Some foods can help regulate body temperature. Hydrating fruits and vegetables, such as watermelon, cucumbers, and citrus fruits, can help cool you down and keep you hydrated. Avoid heavy, hot meals, and instead opt for lighter meals that are less likely to raise your body temperature. Additionally, drinking smoothies or iced drinks made with cooling ingredients can provide a refreshing way to stay cool.

Exercise with Caution

Exercise is important for maintaining overall health, but if you have lupus and are sensitive to heat, it’s essential to exercise with caution. Try to schedule physical activity during the cooler parts of the day, such as early morning or late evening. Water-based exercises like swimming or water aerobics are great options for staying active without overheating. Be sure to listen to your body and stop immediately if you feel too hot or dizzy.

Monitor Your Skin’s Reaction to Sunlight

People with lupus are more prone to skin sensitivity caused by sunlight, which can exacerbate overheating. The ultraviolet (UV) rays from the sun can trigger skin rashes, redness, and even flare-ups of lupus symptoms. Always wear protective clothing, such as wide-brimmed hats, long sleeves, and sunglasses, when outdoors. Sunscreen with a high SPF is a must to protect your skin, even on cloudy days.

If you are planning to be outside for an extended period, seek shade or find a cool, air-conditioned space to rest periodically. The goal is to avoid prolonged exposure to the sun, which can make your body temperature rise and potentially trigger a flare-up.

Monitor Your Body Temperature

Pay close attention to how your body feels in different environments. Take note of when you begin to sweat excessively or feel overheated, and take action to cool down before your body temperature rises too much. Consider using a thermometer to track your body temperature, especially if you experience a fever during lupus flare-ups. If your body temperature consistently exceeds normal levels (above 100.4°F or 38°C), it’s essential to consult a healthcare provider to rule out potential complications or infections.
