Healthcare professional issues caution about potential health hazards associated with using a fan while sleeping during a heatwave.
Sleeping with a fan on all night could potentially cause some health issues, especially for those with severe allergies and asthma. Here's the scoop:
- Irritated Airways:
- Fans can cause hidden stress on the body, leaving the throat and airways irritated. The continuous airflow might restrict blood flow to the muscles, resulting in discomfort.
- Allergy and Asthma Triggers:
- For people with asthma and allergies, the airflow from fans can stir up particles of dust and dirt, which are then inhaled into the lungs. This can worsen symptoms like chest tightness upon waking.
- Dryness:
- Sleeping with a fan on can leave the nasal passages and throat uncomfortably dry by morning. The dry air can irritate the airways, leading to a buildup of mucus in the nose, sinuses, and phlegm in the throat.
- Muscle Problems:
- Cool air against muscles and joints can cause a drop in tissue temperature while you sleep. This may result in muscles tightening and persistent discomfort until your muscles warm up again, like after a warm shower or gentle stretching.
However, it's not necessary to ditch your trusty fan entirely. Here are some tips to help you continue using it while minimizing potential side effects:
- Set a timer to limit the fan's running time.
- Wash bedding more frequently to reduce airborne dust.
- Face the fan away from the bed and towards an opposite wall.
- Keep a glass of water at the bedside to sip if your mouth feels dry.
For people struggling with hay fever, the early arrival of the season could be exacerbated by sleeping with a fan on. The Met Office expects high pollen counts across much of southern England and Wales, so it's important for hay fever sufferers to keep particles out of their eyes, face, and hair by staying indoors where possible. Regularly showering and washing hair, as well as removing clothes when coming indoors, can also help to reduce pollen levels in the home.
As the heatwave hits the UK, it's important to maintain a cool living space. Closing windows during the day and opening them at night when the outside temperature has dropped can help keep your home cool. The NHS suggests this as the best strategy for coping in hot weather.
Take these tips into account to enjoy a comfortable, healthier sleep when the thermometer soars! And remember, regular cleaning of your fan can help keep dust and allergens at bay.
