When we wake up in the morning, it's likely that a nice hot shower sounds far more appealing than a cold one.
And while this may be correct, choosing to go for a colder shower first thing in the morning apparently has its health benefits.
That's according to Dr Karan Raj, who also says that there's a specific time of day where warm showers are the best for our bodies - and sadly it's not right when we roll out of bed.
