NHS doctor explains why you shouldn’t check your phone as soon as you wake up
If the first thing you do in the morning when you wake up is reach for your phone, then you're affecting your performance for the whole day, according to Dr Karan Raj.
The NHS surgeon has become well known for his advice videos on TikTok, with a new one explaining why the last thing you should do is start scrolling first thing.
In the video, he said: "When you wake up in the morning, you transition from a delta brainwave of sleep to a theta brainwave.
"We need this theta brainwave, it helps the brain with learning, memory, problem-solving.
"If you wake up, check your phone – social media, messages, etc., you skip the theta brainwave and go straight to the high-stress beta brainwaves.
"This altered brainwave pattern will affect your performance for the rest of the day!"
As well as busting myths surrounding masks and vaccines for his almost 3 million followers, the TikTok medic has become a bit of a sleep guru.
In other recent videos, he's dished out helpful advice on why we should never hit the snooze button.
He explains on TikTok: "When your alarm goes off in the morning, you're usually nearing the end of your REM cycle.
"If you wake up and get out of bed, your REM cycle ends.
"If you hit snooze and go back to sleep, you put yourself right back into REM sleep.
"So now, when your alarm goes off again, you wake up in the middle of REM."
He says this is why people tend to feel groggy and disorientated.
Hitting snooze also confuses your body clock, so it doesn't know when to wake up, Dr Raj said. "Eventually, it won't know when to go to sleep!"
Doctor explains how long the perfect nap should be – and how to avoid feeling groggy
In another crowd-pleasing video, he explained why it's a bad idea to make your bed in the morning.
He explained: "Making your bed in the morning traps dust mites that have accumulated over night. These microscopic predators, which are less than a millimetre long, feed on the scales of human skin and thrive in moist environments.
"When we sleep at night, our bodies become warm and sweaty, making them prime targets for these mites to feed on.
"They will leave behind excretions, which can give us asthma or allergy-like symptoms.
"So making your bed in the morning traps all this moisture and provides a home for 1.5 million of these bad boys.
"Instead, leave your bed messy just for a while. It exposes these mites to air and sunlight, which dehydrate them and causes them to die."
