Waking up with a stuffy nose and sleeping worse when it rains is likely due to increased humidity and barometric pressure changes triggering nasal congestion and potential allergic reactions, and the most effective treatment is using a nasal steroid spray like fluticasone (Flonase) daily to prevent congestion by reducing inflammation, as supported by the study 1. To address this, try using a decongestant like pseudoephedrine (Sudafed) 30-60mg before bed or an antihistamine such as diphenhydramine (Benadryl) 25-50mg, which can reduce congestion and help with sleep. Some key points to consider:
- Running a dehumidifier in your bedroom will lower humidity levels that contribute to congestion, while using a HEPA air purifier can filter out mold spores and allergens that increase during rainy weather.
- Elevating your head with an extra pillow improves sinus drainage while sleeping.
- These symptoms occur because high humidity causes nasal tissues to swell, while changes in barometric pressure can trigger sinus pressure and pain.
- Additionally, rain increases mold spore counts, which may trigger allergic reactions in sensitive individuals, as noted in the study 2. The study 1 found that cetirizine 10 mg was statistically significantly more efficacious than placebo in the treatment of seasonal allergic rhinitis symptoms in children ages 6-11 years, which suggests that antihistamines can be effective in reducing symptoms of allergic rhinitis. However, the most recent and highest quality study 1 supports the use of nasal steroid sprays like fluticasone (Flonase) as the most effective treatment for preventing congestion and improving sleep quality.
