I recently purchased a clever application for my iPhone which works as an intelligent alarm clock. If like me you are not terribly good in the morning, and you often find that you hit the alarm clock with such regularity that you end up being able to do it in your sleep then you may find this is of some interest.
You may already know, but there are two different types of sleep. Effectively these are simply light sleep and deep sleep. The deep sleep is more often referred to as REM sleep, which stands for Rapid Eye Movement. No one is quite sure why, but when you are in deep sleep your eyes move rapidly from side to side. This may possibly be something to do with the fact that it is while you are in deep sleep that you are dreaming.
Whilst in light sleep you are not dreaming. Your body is resting, and your mind is extremely rested, with very little going on. But as you enter deep sleep your brain starts to sort out and process all of the experiences of the day. Again, no one is exactly sure of the purpose of dreams, but it is known that they form a vital function in ensuring our brains are able to cope the next day.
Our senses are picking up an astonishing array of messages, transmitting this information all at the same time to your brain. Your brain filters out anything that doesn’t seem relevant at the time, files away anything which doesn’t seem right or is in some way problematic, and during REM sleep whilst you are dreaming your brain sorts out all of this information so that it can make sense of everything in preparation for the next day. Quite possibly dreams are simply random noise generated as a by-product of all this processing.
When you first go to sleep you are in light sleep for quite some time. Eventually you will enter deep sleep, but only very briefly. As the night progresses you will enter deep sleep more and more often, and you will remain in deep sleep for longer each time. By the time morning arrives you may well be entering deep sleep for up to an hour every other hour.
The problem is though that if you have set your alarm to wake you up at a set time it is impossible to know whether you will be in light sleep or deep sleep. If you are in light sleep then the chances are you’ll be able to hit the alarm and get up reasonably easily. But if you are in deep sleep it is likely you will struggle to cope, will feel hopelessly disorientated, and extremely tempted to stay exactly where you are. The fact that you are in deep sleep at exactly the same time your alarm is likely to go off only increases the chance that you will find it very hard to wake up properly at a set time.
That’s where this application comes in. By slipping the phone under the pillow before going to sleep it is able to monitor your movement throughout the night. During light sleep you are more likely to move about. During deep sleep you will probably remain pretty much motionless. If I tell my alarm I wish to wake up on or before seven o’clock in the morning that it will monitor my movements through the night, and will use this information to wake me up when I am in light sleep, rather than deep sleep. This might mean that it wakes me up a little earlier than I need, but at least I will feel reasonably awake and alert.
So that’s the application which I have purchased, and have been using with great success. But that’s not the end of the story. Because the real problem is that many people are sleeping on sprung mattresses which fail to provide the sort of even support needed to allow you to enter deep sleep effectively. If your mattress does not offer even support, as a memory foam mattress does, then you will continue to toss and turn, remaining in light sleep for much longer than you should do.
This means that not only will you have less deep sleep throughout the night, but there is a greater chance of you being in deep sleep at about the time you need to wake up. This is simply because if you have not had sufficient deep sleep throughout the night, you’ll be popping in and out of deep sleep more regularly right before you need to wake up. If you don’t have sufficient quality deep sleep then you will almost certainly find that not only do you wake up feeling groggy, but during the day you will feel rather low on energy.
A memory foam mattress offers even support over your entire body, which means that you are less likely to move around at night. This in turn enables you to enter deep sleep more easily, helping you to enter REM sleep in a rhythmic way throughout the night, increasing the chance that you will be able to wake up whilst in light sleep, feeling more awake and more energised throughout the whole day.
If you don’t want to go for a memory foam mattress, then even a memory foam mattress topper will make a very significant difference to not only the quality of your sleep, but also the way you feel the next day. Don’t blame your alarm clock, think about your mattress instead, because that will be where the blame really ought to lie.
