What does the Philips sound machine do?

Philips light and sound machineThis particular sound machine might be a bit left field for some people, but I have become enamored with it and feel that I should share it with you. 

This is not your usual sound machine, because it uses light therapy to help you fall asleep and to wake up. It still uses the sounds to help you drift off to sleep as well, but it focuses more on light therapy than sounds 

It is perfect for people who have problems waking in the morning or for those who hate to wake to the sound of an alarm clock in the morning. So if you are interested in a sound machine to help you fall asleep naturally at night, but are also open to using light therapy – then this might be the perfect sleep machine for you.

  • The gradual sunrise simulator slowly changes from red, to orange and yellow, which gently wakes you from a deep sleep, instead of being blasted awake by the harsh sounds of an alarm clock.
  • The sunset simulator, which emulates the colors of the setting sun , helps you to quietly fall asleep naturally.
  • Any of the five natural and soothing sounds (or your favorite radio channel) can be used to help you fall asleep or can be used to help wake you up in the morning, along with the changing light.
  • The natural sounds help you to relax, so you can fall asleep more easily.
  • Awesome for shift workers who have trouble falling asleep during the day, when they are on night shift and people who have get up early, especially in the dark.
  • The sunset and sunrise lights help travelers adjust to the local time zones.

So if you have a problem falling asleep or you really don’t like the alarm clock in the morning, then the Philips wake up light is the solution to all of your sleeping problems.

This natural light alarm clock is actually a dawn simulator, which uses a unique combination of natural lights and soothing sounds to gently wake you in a more natural way than a regular noisy alarm clock.

What I like about the Philips wake up light

Philips light and sound machineFor many people, they not only have problems falling asleep and staying asleep at night, but they also have problems waking up in the morning. Well, the Philips HF3520 sound machine fixes all of that by using both a sunset and a sunrise light simulator.

With the Philips sunrise simulator you slowly wake to both sunrise light and to natural sounds, making it easier to get up in the morning. The light is cool to the touch and doesn’t need replacing at all, you have a large LED display and a tap snooze function as well.

Points to Ponder

This sleep machine only runs on mains power and not batteries, so you can’t take it camping with you! Also, it is more focused on waking you in the morning, as it doesn’t have any soothing sounds that mask annoying noises. This is not necessarily a bad point, it simply has a different focus than the other sleep machines.

Is the Philips HF3520 Sound Machine and Wake Up Light worth it?

light and sound machineIf you really want a sound machine to block out annoying noises which prevent you falling asleep or staying asleep, then the Philips dawn simulator is most probably not for you.

In this case – check out my Marpac DOHM review here (if you like white noise) or my HoMedics Sound Spa review here (for natural sounds).

I have included the Philips sound therapy light here, because it has a sunset light simulator, which might be enough to help people to fall asleep, particularly shift workers who need to sleep during the day.

Also, it is ideal for people who have problems getting out of bed in the mornings, particularly when it is still dark outside. Feel refreshed and well rested every morning with the Philips HF3520 wake up light.
