When it’s still dark outside and your alarm goes off, your first instinct might be to hit the snooze button. Just 10 more minutes, you tell yourself. And when it rings again, you find yourself hitting snooze, yet again. Just another 10 minutes. And before you know it, you’re locked in this vicious cycle of snoozing and feeling like death when you finally get out of bed. The truth is, all that ‘extra sleep’ isn’t doing your body any good since you’re not actually getting any quality rest. Instead, it’s seriously messing up your sleep-wake cycles and that is bad news for your health. Here’s why.

YOUR HORMONES GET MIXED UP
In the morning, your melatonin levels start falling naturally as a signal to your body that it’s time to wake up. This is when cortisol – also known as the stress hormone – kicks in. Cortisol levels peak just before waking and help to boost your hunger and energy levels to prep you for the day. When you continuously get up, hit snooze and fall back asleep, your brain gets confused. It struggles to correctly register when it should trigger the release of the right hormones. As such, you’ll end up feeling more tired when you finally get out of bed.
YOUR TOILET HABITS SUFFER
Ever noticed how it seems to be easier to poop in the mornings? That’s because digestive functions are also affected by sleep-wake cycles. At night, your colon generally lies dormant as you sleep. But once you wake, your colon does the same and starts contracting to move poop down your intestines, priming you for toilet time. Hitting the snooze button five or six times is going to disrupt this process and can cause your poop habits to be thrown out of whack.
YOU MAY FEEL HUNGRIER IN THE DAY
Similarly, your tummy also stirs once you wake up. Ghrelin, the hormone that increases appetite, should rise when your alarm goes off . But when you constantly shut it down by putting your body through a sleep-wake sleep wake cycle, your hunger cues go haywire. Your body might release ghrelin earlier or later than normal and trigger hunger pangs at strange timings of the day, such as just before bed or in the late morning, causing you to snack or eat more.
YOU FEEL GROGGIER
If it’s hard to peel your eyes open when your alarm sounds in the morning, it’s going to be even harder when you let yourself fall back asleep only to be jolted awake 10 minutes later. Your body can’t figure out when it’s supposed to kick-start the hormones associated with being awake and this can make it even harder to get out of bed. Worse still, this brain fog may last throughout the day and leave you lethargic and unproductive. The same thing applies if you naturally wake up just before your alarm – don’t force yourself to go back to sleep for that extra 10 or 15 minutes. You’ll end up feeling groggier than if you’d just gotten out of bed early.
