Feel tired during daytime? Need a nap? HappyNap gives you a real Power Nap!

Scientific experiments have shown that a short nap between 15-30 minutes is very useful. It gives you:
- increased daytime alertness
- increased productivity
- refreshed feeling
- decreased stress factors

HappyNap gives you a nap of 15 to 30 minutes depending on your tiredness.


DETAILED INFORMATION:

The HappyNap technology is based on medical research of the human sleep and its structure. It looks for the optimal and natural wake up moments for your body and brain. These kind of subconscious moments of wakefulness are common when taking a nap. They are the optimal moments to wake up (see picture).

HappyNap uses mobile phone microphone to detect the wake up moments. It may wake you up between 15 - 30 minutes at an optimal moment with a gentle alarm signal. If you are tired and need a longer nap, you get up to 30 minutes of sleep.

The human sleep consists of different stages of sleep (see attached picture). Stage 1 is very light sleep, Stage 2 is light sleep, and Stages 3-4 & REM are deep sleep. Waking up during sleep stages 3-4 or REM is difficult. This difficulty is called "sleep-inertia": you feel groggy and even more tired than before the nap. To avoid the sleep-inertia it is reasonable to wake up before deep sleep. Therefore, a nap with duration of less than 30 minutes is recommended.


UPGRADE TO FULL VERSION:

HappyNap is a lite version of the HappyWakeUp® application, which is the first mobile smart alarm clock.

With HappyWakeUp® smart alarm clock you get:
- an easy and refreshed wake up
- no groggy feeling
- a possibility to achieve more active minutes in the morning
- decreased stress factors by a pleasant wake up

Both applications are results of a Finnish study conducted in the Tampere University of Technology and the University of Helsinki. The technology is patented.
