Experts indicate that despite the refreshing feel of cold showers, they might not reduce core body temperature during hot weather. Professor Adam Taylor explains that cold exposure constricts blood vessels near the skin, hindering heat loss and potentially trapping heat within internal organs. This action can deceive the body into conserving heat rather than cooling off, leading to inefficient temperature regulation. Cold showers may also present risks for individuals with cardiovascular issues due to the cold shock response, which elevates blood pressure and can pose further health risks.
'Although diving into a cold bath or shower straight after being out in the heat might feel nice on your skin, it isn't doing what is needed to reduce the core temperature of the body.'
'When exposed to cold [such as a cold shower] the blood vessels near the skin constrict, reducing the blood flow into these areas.'
