Technologies that help 'comfort' sleep

Recently, in the US market, there have been a number of special electronic devices and application software, promoted to help users get a better sleep.

For Lisa Hanson - a San Francisco housewife, her 'alarm clock' is a babbling child. Every morning, she wakes up at 5:30 and starts making noises that make her awake. 'So the whole morning I was mentally ill because I was awakened when I was sleeping best,' she said.

However, last month Hanson began using Renew SleepClock program - a new application for iPhone phones - to monitor his sleep. Producer GEAR4 said the application uses radio sensors to measure user breathing and movements at night, then use that information to wake them up when they sleep at a stage. The deepest part. According to a study, when awakened at this stage, people will avoid being ecstatic and indifferent, which makes them want to go back to bed. Manufacturers claim that the application also acts as a 'sleep consultant', only to tell you how long it takes to sleep and how to get the fastest nap.

'Since I used it, I woke up more in time and thanks to that, I had a very clear day,' said Hanson. Currently Renew SleepClock, cost about 199 USD, is the latest application in a series of smart phone applications designed to help users improve sleep.

After Renew SleepClock, two other notable products are WakeMate - a bracelet capable of transferring data to the phone - and Zeo Sleep Manager Mobile - a headband with a sensor that helps capture pulse data around user sleep habits.

The similarity of these devices is to require users to choose a time period, lasting 20-40 minutes, in the morning they want to be called up. After that, the device will choose when they sleep the deepest during this time to wake them up. Every morning, these devices will conduct a 'score' of the user's sleep, through factors such as the number of hours of sleep, the number of startups, the time spent in the deep sleep phase and the recovery period. recovery of sleep.

However, the above devices also have positive aspects but also have limitations. Dr David M. Rapoport - sleep specialist at the Department of Medicine, New York University - said the tools help to provide accurate and truthful information about sleep that is useful for us to follow. sleep monitoring and adjustment. However, it does not provide useful and appropriate advice to users. For example, the above programs often require all users to sleep 8 hours / night but actually the sleeping needs of each body are not the same. Besides, Dr. Rapoport said that the theory of awakening a person when they are in the deepest sleep phase will help avoid fatigue and is not really unified in many studies.
