With warm days comes sticky nights, and many are looking for ways to cool down inside. One thing that can be tempting to do when temperatures rise is sleeping with a fan on. But it turns out this can be dangerous for your health. According to The Sleep Advisor blog, sleeping with a fan on can cause an allergic reaction.

Sleeping with fan on can be bad for your health – here are other ways to cool down

Circulating the air, including dust and pollen, around the room can trigger an asthma attack and hay fever. Constantly blasting cool air around the room can also cause dry skin and dry eyes.

Some people sleep with their eyes partially open, and a steady airstream can cause major irritation. For those who can't help but sleep with their mouths open, this is the same. The excess airflow can dry out mouths and throats. Another downside of sleeping with a fan on is that it can dry out your nasal passages, which can affect your sinuses.

The NHS recommends keeping rooms cool by "using shades or reflective material outside the windows. "If this is not possible, use light-coloured curtains and keep them closed (metallic blinds and dark curtains can make the room hotter)." If you can, try to move into a cooler room for sleeping. It's important to keep hydrated throughout the day – drink plenty of fluids and avoid excess alcohol. Co-founder of BOXT.co.uk Andy Kerr previously shared several tips on how to keep your room cool to Daily Star Online. One tip involves using a hot water bottle as an ice pack. Simply fill it with cold water, and pop it in the freezer. Other tips from Andy include investing in house plants, changing your bedding to linen and opening the windows after dark.
