Waking up tired? In some cases, fatigue can be traced to allergies. Ironically, some allergy medicines may be the cause of allergic fatigue. Decongestants may cause insomnia. Antihistamines may cause fatigue. Either of these can throw off your normal sleep patterns, making it hard to enjoy a good night’s rest.
Sleep can also be disrupted by allergic rhinitis characterized by a stuffed-up or runny nose. If your nasal passages aren’t clear during the night, irregular breathing can interrupt sleep.
Finally, an allergic reaction itself may also contribute to allergic fatigue. During this reaction, the body releases chemicals to battle what it deems are intruders. These chemicals are intended to neutralize invading particles such as allergens like mold, pet dander, and pollen. As the body releases these chemicals, they can trigger inflammation affecting various systems of the body. This can result in fatigue because the body‘s resources are depleted.
Managing Allergic Fatigue
Handling allergic fatigue involves taking efficient steps to minimize allergies. The proper medication can help as well as limiting exposure to allergens. If taking allergy medications, avoid taking them at times when they could disrupt sleep. For example, don’t take decongestants that could perk you up just before bedtime. Also, consider allergy immunotherapy (through shots or drops) if you have allergies for more than a few months of the year. The advantage of allergy immunotherapy over pills or nasal sprays is that it treats the underlying allergy—not just its symptoms.
