If you're one of the millions of people who can only crawl out of bed in order to drag yourself down to the kitchen for a fresh cup of coffee, you're certainly not alone. So many of us feel like we can't even function, let alone speak to anyone or get any work done, until we've had that sweet sip of Joe to satisfy our caffeine needs. However, it turns out we've gotten it all wrong, and in actual fact, we should be letting our bodies naturally do the work. Speaking on BBC Morning Live, Dr Karan Raj, famed for sharing health tips on TikTok, warned we absolutely shouldn't be drinking coffee first thing in the morning. "Don't drink coffee first thing in the morning to wake you up," he said, in a clip which was later shared to his TikTok. "Your body naturally wakes you up with cortisol, you get a cortisol spike in the morning." Instead, Dr Raj suggests saving that caffeine hit until later in the morning, once those natural cortisol levels reduce and you're left with a little energy slump. "Save your coffee until mid-morning when your cortisol levels and your energy levels dip so you get a caffeine boost then and it'll be better," he said.
