Method and system for monitoring and improving sleep pattern of user

1. A method for providing feedback to a user for adjusting sleep pattern of the user, the method comprising:

collecting a set of information related to the user;

receiving a set of measurement data related to the user from a wearable electronic device;

defining a circadian rhythm and a duration of sleep of the user;

determining sleep scores for a predefined number of days, wherein a sleep score is determined for each of the predefined number of days from the collected set of information, the set of measurement data, the circadian rhythm and the duration of sleep of the user, and associating each sleep score with a corresponding go-to-bed time or a time of falling asleep of the user;

analysing the sleep scores and associated go-to-bed time and/or time of falling asleep of the user to determine an optimum bedtime window for the user; and

providing feedback to the user based on the analysed sleep scores and the optimum bedtime window, wherein the feedback comprises first instructions comprising a first go-to-bed time corresponding to a first night and second instructions comprising a second go-to-bed time corresponding to a second night, the second go-to-bed time between the first go-to-bed time and the optimum bedtime window.

2. A method of claim 1 , wherein providing the feedback is further based on a set of measurement data for a consecutive day, wherein the consecutive day is succeeded by the predefined number of days.

3. The method of claim 1 , wherein the duration of sleep is measured as a time between moment of falling to sleep and moment of waking up or as a time between moment of going to bed and moment of waking up, wherein said moments are determined based on at least one of pre-defined changes in heart rate, pre-defined changes in body or skin temperature and changes in movement of the user.

4. The method of claim 1 , wherein the set of information comprises physiological performance related information based on an external data input by the user.

5. The method of claim 4 , wherein the external data comprises at least one of travel information, time zone, calendar, working schedule and holidays.

6. The method according to any of the preceding claims, wherein the method further comprises storing a set of parameters related to sleep patterns.

7. A system for providing feedback to a user for adjusting sleep pattern of the user, the system comprising:

a wearable electronic device configured to be worn by the user and comprising means for measuring a set of measurement data;

a mobile communication device configured to communicate with the wearable electronic device and operable to collect a set of information related to the user;

wherein the mobile communication device or the wearable electronic device is operable to measure a circadian rhythm and a duration of sleep of the user; and

a processing module configured to communicate with at least one of the mobile communication device and the wearable electronic device, the processing module operable to:

receive the set of measurement data related to the user from the wearable electronic device;

receive the set of information related to the user from the mobile communication device;

receive the measured circadian rhythm and the duration of sleep of the user from the wearable electronic device or the mobile communication device;

determine sleep scores for a predefined number of days, wherein a sleep score is determined for each of the predefined number of days from the collected set of information, the set of measurement data, the circadian rhythm and the duration of sleep of the user, and associate each sleep score with a corresponding go-to-bed time or time of falling asleep of the user;

analyse the sleep scores and associated go-to-bed time or time of falling asleep of the user to determine an optimum bedtime window for the user; and

provide feedback to the user on the mobile communication device, based on the analysed sleep scores and the optimum bedtime window, wherein the feedback comprises first instructions comprising a first go-to-bed time corresponding to a first night and second instructions comprising a second go-to-bed time corresponding to a second night, the second go-to-bed time between the first go-to-bed time and the optimum bedtime window.

8. The system of claim 7 , wherein the wearable electronic device is operable to measure a set of measurement data for a consecutive day, wherein the consecutive day is succeeded by the predefined number of days and the processing module is operable to provide the feedback further based on the set of measurement data for the consecutive day.

9. The system of claim 7 , wherein the processing module is operable to store a set of parameters related to sleep patterns.

10. The system of claim 7 , wherein the mobile communication device or the wearable electronic device comprises the processing module.
