(Sleep tight) Turn off the electric blanket 'now' to stay awake all night

To get a good night's sleep, it's best to turn off the electric blanket just before going to bed.

 

Temperature is a crucial factor to consider for quality sleep. To achieve deep sleep, your core body temperature needs to drop by 1 to 1.5 degrees Celsius. A study led by Professor Matthew Walker of the Department of Neuroscience at the University of California found that if your core body temperature remains high, your brain cannot transition into a sleep state and instead repeats light sleep. Professor Kang Seung-geol of the Department of Psychiatry at Gachon University Gil Hospital stated, "Even if the temperature is low, sleeping with an electric blanket on can disrupt deep sleep because your body temperature will not drop. This can cause you to awaken during REM sleep, which can lead to waking up in the early morning." As your body actively regulates its temperature to maintain sleep, it can continuously sweat, which can lead to dehydration.

 

Electromagnetic waves from electric blankets also disrupt sleep. .

 

According to Professor Kim Yun-shin's team at Hanyang University, even a magnetic field of 2mG or higher increased the secretion of melatonin, which affects circadian rhythms and the immune system. Magnetic fields of 20mG or higher also increased the secretion of the stress hormone cortisol and increased heart rate variability during sleep. The Ministry of Environment recommends using products that have received the "Electromagnetic Field Environment Certification (EMF)" standard, which specifies that electromagnetic waves use levels of 2mG or lower.

 

This doesn't mean you shouldn't turn on your electric blanket at all. Timing is key, and turning it off right before bed can actually help you sleep better. Professor Choi Ji-ho of the Otolaryngology Department at Soonchunhyang University Bucheon Hospital explains, "When your body temperature rises and blood vessels dilate, heat dissipation improves, which lowers your body temperature and helps you fall into a deep sleep more quickly." He adds, "To prevent rapid temperature changes, adjust the room temperature to a comfortable level, then turn off the electric blanket before going to bed." Even when turning on an electric blanket before bed, it's best not to leave it above 40 degrees Celsius (104 degrees Fahrenheit), as this can cause low-temperature burns. Unlike regular burns, low-temperature burns from electric blankets don't cause immediate pain, which can lead to more serious damage. It's reported that over 80% of patients seeking treatment for low-temperature burns have damaged the dermis, requiring skin grafting.

 

Meanwhile, as electric blankets are heating devices, quality and safety management are important. The Korea Consumer Agency recommends ▲when purchasing electric blankets, choose products with the KC mark and safety certification number.

▲Check if the manufacturer or seller provides normal after-sales service.

▲When not in use, be sure to unplug the power cord or turn off the switch.

▲When storing, roll it up to prevent damage to the heating wire.

▲We recommend that you do not stack heavy objects on top of the electric blanket.

 

 

=============

Instead of sleeping with the electric blanket on,

Turning it off right before falling asleep is the "best sleep"

I guess it's a point~

 

It's hotter today than yesterday

Just turn it off and go to sleep

Isn't it a little cold in the morning?
