Enabling wearables to cognitively alter notifications and improve sleep cycles

A method for cognitively adjusting a notification alert delivery time, the method comprising:

• receiving a message notification from a sender;
• determining an importance of the received message notification based on a plurality of notification attributes and a plurality of person attributes that are each associated with the received message notification;
• in response to determining to alert a user of the received message notification based on the determined importance, identifying a current user sleep stage, wherein the current user sleep stage is REM or NREM, and wherein the NREM sleep stage is selected from a group consisting of N1, N2, and N3;
• in response to determining the current user sleep stage will not minimally impact the user, tuning one or more wearable technology device parameters for a next sleep stage, wherein tuning the one or more wearable technology device parameters for a next sleep stage further comprises:
• calculating a minimum amount of time left in a user sleep cycle, wherein the minimum amount of time left in the user sleep cycle is calculated as T=ANTDmin+n+tprev, and wherein T is the time left in the user sleep cycle, ANTDmin is a minimum allowable notification time delay of the current and remaining sleep stages, n is a total amount of time elapsed in the current sleep stage, and tprev is a sum of an elapsed time in each previously completed sleep stage;
• modifying the notification delivery time based on the calculated minimum amount of time left in the user sleep cycle;
• and
• in response to determining the current user sleep stage will minimally impact the user, transmitting the received message notification to a user device.
