An NHS doctor has recommended that people wear socks when they're in bed.
Socks
Dr. Karan Raj has amassed millions of followers on TikTok with his bitesize medical pointers, and has now told his followers to wear socks as they sleep as it increases blood circulation to the feet - which gets rid of heat and allows your core body temperature to cool down quicker than normal.
Raj explained: "You need to start sleeping with your socks on, and here's why ... Wearing socks to bed increases the blood circulation to your feet this causes your blood vessels to vasodilate - they widen.
"When the blood vessels widen they can get rid of heat much quicker because of the much bigger surface areas.
"This allows your core body temperature to cool down at a faster rate than normal, and a lower core body temperature is needed for optimal sleep.
"If you want better feet, cover your feet."
