NHS Doctor Karan Raj has disturbed his 2.3m TikTok followers by urging them to wear socks to bed.

The doctor said: "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."
