Garfield is the movie icon who most perfectly sums up that Monday morning feeling. The ginger cat's hatred of early rising is a feeling which resonates deeply in most of us. Sometimes it's just impossible to wake up!

But did you know that, far from being pure laziness, there are actually scientific reasons to explain why some of us hit snooze on repeat while others can just leap out of bed in a flash?

Learn why some of us find mornings harder than others, and what we can do to feel more refreshed when we wake up!

▲There are some people who seem to be living in the wrong part of the planet.

▲

This is because while the rest of the world is sleeping, they seem to be most productive during the night.

Whether it's watching movies, series, reading or just doing nothing, there are people who prefer to be awake at night.

▲

It's as though someone were living in Europe, but with the biological clock of someone living in Japan.

This naturally causes problems in waking up early the next day.

▲But there are people who don't even go to bed that late, but who still have issues in waking up early. What are the reasons behind this?

▲Scientists seem to have found an explanation for the issue. According to an article published in Frontiers in Neurology the reason could be genetic.

▲The discovery was made in a study on insects who have similar biological clocks to humans. The study was carried out on flies by researchers from the University of Leicester.

▲The flies were separated according to those which had nocturnal habits and those with day habits.

▲From the study, it was discovered that there are about 80 genes which are linked to sleeping patterns.

▲The study confirmed that people who prefer doing things at night are not behind people who work best during the day.

▲The explanation comes from the genes of these two distinct types of people, which are completely different and responsible for their productivity at different times of the day.

▲Independent of whether the genetics answer is right or not, one thing is for certain: when working or studying, it's often necessary to wake up early. So how can we adapt?

▲The British publication Metro compiled a list of tips to help you wake up early as easily as possible.

▲One tip is to avoid the deadly snooze button, and to realize that an extra 10 minutes in bed isn't going to make it any easier to get out of it.

▲When you decide to sleep for just a few more minutes, your brain slips back into a state of deep sleep which makes you feel even more tired when the alarm goes off again.

▲

So it's best to set your alarm for the exact time that you need to get up. If you start to create a habit of always waking up at the same time, then it will get easier.

▲As difficult as it may seem to go to bed early, try to enforce a strict bed time at the same time every night, so that your body can get used to this.

▲Another tip has to do with the weekends. As much as you may want a lie-in on the weekends, remember that this will put your body out of sync with the routine you create for yourself during the week, meaning that it will struggle to adjust back to that come Monday morning.

▲The same thing happens when you go out late at night and drinking: your body clock is pushed out of routine.

▲

If you spend all night out during the weekend, then you will find it hard to get back to your routine and feel more tired when you hit the daily grind again.

▲Before going to sleep make sure you disconnect from all electronic devices. Watching a screen for a long time will make it harder to fall asleep, and you'll wake up feeling tired.

▲As difficult as it can be, try to be strict with the time you wake up, especially during the winter.

▲During winter the body usually suffers from two key things: a lack of vitamin D and changes to the time daylight appears, so it's worth keeping a strict waking and bedtime to help with this.

▲To finish off with, two simple tips. Firstly, avoid doing physical exercise close to bedtime, as this wakes your body up and makes it harder to get to sleep.

▲

The second tip is to go and chat with a doctor if you are having constant difficulties in setting wake up and bedtimes. They could recommend some treatment which might help.
