Sleeping With A Fan

Hot nights are becoming more common in the UK, and since only a small percentage of homes have air conditioning, many people turn to electric fans for relief while sleeping.

However, health expert Dr. Naheed Ali cautions that sleeping with a fan on all night may have some unintended health effects.

One common problem is dryness. Continuous airflow can dry out the throat and nasal passages, which may lead to thicker mucus, congestion, a hoarse voice, or ongoing coughing during the day.

Fans can also worsen allergies or asthma. By circulating dust, pollen, pet dander, and other particles, they may trigger symptoms such as sneezing, wheezing, or chest tightness in sensitive individuals.

Another possible issue is muscle discomfort. Cool air blowing directly onto the body can cause muscles, especially in the neck and shoulders, to tense up, leading to stiffness by morning.

Still, there are ways to use a fan more safely at night. Setting a timer to switch it off after about 90 minutes can help you cool down without prolonged exposure.

It’s also helpful to direct the fan away from your body, stay hydrated by keeping water nearby, and reduce allergens by regularly washing bedding and maintaining clean air filters.
