John Scholl, an expert in vascular surgery at University College London Hospital, said air conditioning and heating temperatures were too high, indoor and outdoor temperature differences were too large, and small blood vessels were easy to contract suddenly when going out, making people feel colder. Therefore, it is best to set the indoor temperature to 18℃~20℃.

Eddie Charona, a vascular surgery expert at Lewisham General Hospital in the UK, said caffeine dilates blood vessels, making them less likely to contract naturally in cold conditions, causing heat loss in the body and making people feel colder.
