Sneezing, itching, a runny nose, or swelling in various regions of the body are examples of allergic reactions that may be recognizable. Nevertheless, allergies can induce fatigue and weakness in some people (allergy fatigue).

How can allergies lead to fatigue?

The immune system's response to a foreign substance that should not be harmful is known as allergy. Some individuals do not experience any reaction to foreign substances that induce allergies. However, for certain people, exposure to allergens is perceived as a threat, resulting in the body producing responses such as swelling or irritation as a form of resistance.

Coughing, itchiness, sneezing, skin irritation, and a runny nose are among the most prevalent allergic reactions. Nevertheless, allergies can also induce fatigue in some people, including weakness and a lack of energy. 

According to the Advanced Ent & Allergy Center page, allergies can lead to fatigue through the following mechanisms:

Ongoing immunological response

The immune system quickly responds to allergen exposure by producing and releasing histamine, a chemical that protects the body from the allergen. Constant exposure to allergens causes the immune system to remain hyperactive, which in turn causes the immune system to become weaker. You become more susceptible to various diseases because of this.

Lack of sleep

Several allergy symptoms, such as a runny nose, coughing, sneezing, or blocked nose, may disrupt your sleep at night. With this condition, you have trouble falling asleep or wake up frequently during the night. You thereby become unhealthy, weak, and energy-less.

Brain fog

Certain allergic reactions, such as blocked noses and swelling, can impair cognitive function, commonly referred to as brain fog. This condition is a result of obstructed passages in the nose and increased pressure in the nose airways, which impairs your ability to focus.

Impact of medications

While allergy medicine may relieve allergy symptoms, it can also induce fatigue in the body. Allergy treatments contain antihistamines, which have the well-known side effect of causing drowsiness. Insufficient sleep can result in fatigue, weakness, and a lack of energy in the body.

Sleep apnea

Allergies might worsen specific sleep disorders, such as sleep apnea. Manifestations such as inflammation and nasal blockage impede adequate respiration, exacerbating snoring or sleep apnea.

As a result of the obstruction of the airways, the lungs and the heart have a difficult time receiving adequate oxygen. The lack of air causes you to have restless sleep, which results in you waking up feeling fatigued and restless.

How to manage body weakness and fatigue due to allergies

The following is a list of treatment options that you can consider if you are experiencing fatigue or weakness as a result of allergies:

• Identify allergens. To overcome body weakness or brain fog from allergies, recognize what causes them. You may take an allergy test at a clinic or hospital if you don't know what caused the reaction.
• Avoid exposure to allergens. Once you know what caused the reaction, you should stay away from the allergen as much as possible. For example, if you are allergic to dust and pollen, you should regularly clean some parts of your home and wear a mask when you are outside, especially when the wind is strong.
• Take medication. It is advisable to take allergy medication as your doctor has prescribed if an allergic reaction interferes with your daily activities.

Certain allergic reactions might result in symptoms such as fatigue, muscle weakness, and brain fog. If you need medical advice or consultation, you can either visit a doctor or make use of the consultation features that are available in the Ai Care application by downloading the Ai Care application from the App Store or Play Store.
