Do you know that sleep is as important as exercise and diet to your body? Sleep replenishes energy, makes you active and keeps you healthy lack of which can land you in much trouble than you could imagine. The advent of smartphone era and electronic gadgets has ruined our lifestyles, pushed our sleep hours dramatically to 12 or 1 o clock in the night and shift work has brought upon a culture where we eat and sleep anytime of the day or night without minding our natural body clocks and circadian rhythm. Circadian rhythms are integral to each of us regulating our sleep-wake cycles and feelings of sleepiness/wakefulness over a 24-hour period. It works based on the area of the brain that responds to light which clearly shows why we sleep when its dark and remain alert when the outside sun shines brightly. We humans have evolved into creatures who don’t listen to our parents, siblings, spouses or anyone else doing what we like and liking what we do. While we do understand the importance of sleep with regards to regular bed timings, wake up hours and sleep duration to keep us healthy we don’t monitor the same nor do we try doing it. The invention patented here comes to our rescue here as it helps in assisting and guiding the user to set goals that promote consistent sleeping behavior. In fact, the methods and techniques discussed here promote sleep consistency and improve sleep quality.
While the general recommended hours of sleep are between 7 and 9 hours sleep requirements and durations differ from person to person in order to lead a healthy life. The invention here comes with a personalized recommended sleep duration that’s more precise (for example, 8 hours ±0.5 hours) in comparison to 7-9 hours that’s recommended generally. A ‘sleep session’ is the period of time during which the individual is actually sleeping or attempting to sleep too. It depends on the sensors too-sensors might indicate the time beginning from when a person first enters the bed to sleep, the individual might manually indicate to a biometric monitoring device the beginning of a sleep session or when a processor determines that the individual has started to sleep. Likewise, the end of the sleep session might be noted when the person exits a bed, the individual manually notes the end of the sleep session on the biometric monitoring device or again, if the processor has determined when the person stops sleeping. The start and end time of sleep sessions depend on the criteria used to determine the parameters. Wearable fitness trackers such as Fitbit might be treated as biometric monitoring devices to collect biometric sensor data or it might even be sleep-monitoring systems attached to mattresses or even operating from somewhere close by such as from a nightstand or so.
An individual goes through different states such as awake state, asleep state, waking state, etc., Again in sleep state the individual might be in REM or non-REM state and its not mandatory that an individual passes through each of the states while sleeping and the sleep duration determines the amount of time an individual spends in one or more sleep states that represent one or more stages of sleep. The biometric monitoring device might determine the time spent in each of the sleep states. After obtaining sleep parameters such as selected sleep duration, scheduled waketime and selected bedtime along with the individual’s selected sleep duration the individual’s sleep schedule may be tracked to find out how consistently the individual is meeting sleep duration goals. Sometime down the line the individual’s scheduled waketime and selected bedtime might also be clocked. Sleep monitoring is done by storing the sleep data in a sleep log data store that associates logs with specific users and sleep efficiency is calculated by monitoring the total time in a sleep session that an individual is in one or more sleep states or is not in an awake state divided by the sleep session duration. For instance if an individual goes to bed at 10.00 pm and falls asleep after 30 minutes, wakes up through the night for a total of 30 minutes and finally wakes up at 6.00 am in the morning the total time duration in bed is 8 hours (10.00 pm to 6.00 am) but he/she was actually sleeping (non-awake state) only for 7 hours (excluding 30 minutes to fall asleep and 30 minutes of waking up through the night). The sleep efficiency of the individual is 7 hours divided by 8 hours which is 0.875. Sleep efficiency changes based on different factors such as sleep environment, physiology, caffeine intake, timing at which the person retires to bed and so on. For example, if the person goes to bed early then he/she is less tired and spends more time trying to fall asleep but if the person goes to bed later, he/she is more tired and falls asleep more easily. In practice, sleep efficiency is always lesser than 1.
The invention displays a bedtime reminder in advance to remind the user to go to bed. Sometimes, snooze option in the reminder is also possible and the reminder is generally set based on the sleep state duration data of the user for the previous sleep session. The user might even be congratulated after a sleep session in which the user achieves bedtime target. The invention is of paramount importance as it guides the user and sets the user’s sleeping routine in a disciplined way.
