Cold air from fans can cause muscle contractions, leading to soreness and cramps
Fans have become a necessity in the hot weather, helping to maintain a cooler room temperature, reduce electricity bills, and promote air circulation. However, despite these benefits, the cold air from fans can also cause muscle contractions, leading to soreness and cramps.
Several people have reported experiencing muscle soreness and cramps after sleeping with a fan on. The concentrated flow of cool air from fans has been found to make muscles tense up and cramp, resulting in soreness upon waking up. This phenomenon has even been given a name, "colpo d'aria" or "hit of air", in some cultures.
The discomfort caused by the cold air from fans can be particularly noticeable for those with pre-existing muscle pain. For such individuals, the cold air can aggravate the pain and make it worse. In addition to muscle soreness, the cold air from fans has also been associated with other health issues, such as dry eyes and skin, congestion, and triggering allergies.
To minimize the negative effects of using a fan, there are several measures that can be taken. One effective way is to keep the fan at a distance, pointing it away so that the air does not blow directly on the body. Using a timer to turn the fan off after a few hours can also help reduce exposure to the cold air. Additionally, ensuring that windows are open and air is circulating can prevent the buildup of cold air in a closed room.

Fans can worsen pre-existing muscle pain
Fans can be a great way to keep cool, especially during hot summers. However, they may also have some negative impacts on your health, including worsening pre-existing muscle pain.
Some people have reported that sleeping with a fan on can lead to muscle soreness and stiffness, especially in the neck and back. This could be due to the concentrated airflow causing muscles to tense up and cramp, which can be mitigated by pointing the fan away from the body so that the air does not blow directly onto you.
In certain cultures, it is believed that exposure to cold air from fans can lead to more severe issues. For example, in Korean culture, it is thought that running an electric fan in a closed room can be fatal, a belief known as "fan death". While there is no concrete evidence to support this claim, it is a widely held belief that persists today. Similarly, in Slavic cultures, exposing oneself to drafts or open windows is thought to be harmful, with the circulating air believed to be the "number one cause of 'mouth behind the ear'".
To minimize the negative effects of using a fan, it is recommended to keep the fan at a distance, set a timer to turn it off after a few hours, use air filters, or place a bowl of water in front of the fan to add moisture to the air. Additionally, those with pre-existing muscle pain may find that their discomfort worsens when sleeping with a fan on, so it is advisable to avoid direct exposure to the airflow in such cases.

Fans can cause neck pain and stiffness
The concentrated flow of cool air from fans can cause muscles to tense up and cramp, leading to soreness. This can be prevented by pointing the fan away so that the air does not blow directly on you. Keeping the fan 2 to 3 feet away and using an oscillating fan can also help to prevent a direct flow of air.
Some people have also credited their lack of neck and back pain to the moment they stopped using a fan. However, there is no scientific explanation for this, and it may be more prevalent in cultures that are not used to air conditioning.

Fan death is a belief in Korean culture, where a fan in a closed room is fatal
While there is some anecdotal evidence that sleeping with an electric fan on can cause muscle pain or soreness, there is no scientific backing for this claim. However, it is interesting to note that in Korean culture, there is a widespread belief in "fan death", which states that running an electric fan in a closed room can be fatal.
Fan death is a long-standing superstition in Korea, with reports of it dating back to the 1920s and 1930s when electric fans were first introduced to the country. Stories from this time warned of the risks of nausea, asphyxiation, and facial paralysis from using electric fans. The belief persisted well into the 2000s, with local media, fan manufacturers, government agencies, and even some health practitioners warning people against using electric fans at night. It was claimed that sleeping with a fan on could lead to suffocation or hypothermia and that the risk was higher for the elderly and those with respiratory problems.
There are several theories as to why fan death was so widely believed in Korea. One conspiracy theory suggests that the South Korean government propagated the myth to curb energy consumption during the 1970s energy crisis. Others speculate that the authoritarian government at the time was trying to cut back on electricity usage to manage higher energy prices. Still, others believe that the occasional news story mentioning fan death, coupled with public service warnings about the dangers of hypothermia and suffocation, helped to spread the fear.
It is worth noting that there is no scientific evidence to support the claim that electric fans can cause death. In fact, experts say that running a fan in the summer would not cause any of the alleged health threats, especially hypothermia. Despite this, the belief in fan death was so strong that even those who disbelieved it would take precautions, such as keeping a window open or setting a timer on their fan.
Today, the belief in fan death seems to be fading, especially among younger Koreans. A decade of internet skepticism has likely contributed to this shift, with many realizing that fan death is probably just a superstition. However, the persistence of this belief for so many years and its influence on Korean culture cannot be understated.

Fans can cause dry skin and eyes, which can be mitigated with moisturisers and eye drops
Fans can be a great way to keep cool at night, especially during hot weather. However, they can also have some negative effects on your body, such as causing dry skin and eyes. This is due to the constant blast of air removing moisture from your skin and eyes, leaving them feeling dry and irritated.
To mitigate these issues, there are several steps you can take. Firstly, consider using moisturisers as part of your bedtime routine to combat dry skin. Secondly, for dry eyes, eye drops designed to relieve itchiness and dryness can be very effective. Additionally, you can minimise the drying effects of the fan by keeping it at a distance, using a timer to turn it off after a few hours, or placing a bowl of water in front of the fan to add moisture to the air.
It is worth noting that the direct airflow from a fan can also cause muscle contractions, leading to soreness and aches, particularly if you already experience muscle pain. To reduce the likelihood of muscle aches, avoid having the fan blow directly on you, and instead, point it away or use an oscillating fan to prevent a concentrated airflow.
By following these simple steps, you can continue to enjoy the cooling benefits of a fan while minimising any negative impacts on your skin, eyes, and muscles.
