MOST of us head to the kettle as soon as we wake up.
But a cup of coffee first thing isn’t the best way to get an AM energy boost, according to a sleep expert.
Caffeine works by blocking sleep-promoting receptors in your brain called adenosine receptors, duly making you feel more alert.
But blocking these receptors within minutes of your alarm clock going off isn’t very good for your health.
Dr Deborah Lee, Get Laid Beds’ resident Sleep Expert, said that this is due to your cortisol levels.

Cortisol is the hormone that enhances alertness and focus, as well as regulates your metabolism and immune system response.
“When you wake up, your stress hormone cortisol level is at its peak,” Dr Deborah explained.
“Elevated levels or cortisol can impact your immune system, and if they’re already at a peak when waking up, drinking coffee as soon as your eyes open may do more harm than good.
“This may even make you immune to caffeine over a long period of time.”
According to the sleep expert, the best time to have a cup of joe is after 10am for maximum caffeine uplift.
“The best time to drink coffee would typically be to drink mid-to-late morning when your cortisol is a lot lower and you can start to feel that energy slump,” Dr Deborah said.
“But of course, not too late in the afternoon as it could affect your sleep.
“If you’re someone that wakes up at around 7am, leaving your first coffee until around 10am to 12pm will be when your body, and mind, will appreciate it the most.
“And you’ll get the most benefits from the caffeine.”

She added that you should stop drinking coffee “at least six hours before you sleep” to stop it from disrupting your rest.
“To avoid messing up your sleeping pattern, avoid any caffeine after 3pm including coffee, fizzy drinks, energy drinks and even tea,” Dr Deborah said.
“Try switching to herbal teas if you need a hot drink to stay warm, or decaf to trick yourself into thinking you’re getting your caffeine fix.
“Your sleep schedule will thank you!”
