 If you tap on the CSV or ZIP file that was exported from Sleep (anywhere - in your email attachment, Drive, Dropbox, file manager), the system will offer to open it with Sleep as Android. This will import the included sleep records.

+== Import sleep noise files
+
+If you wish to import sleep noise files to a new phone, you need to do this manually by copying the folder to the storage on the new phone.
+
+Yo
+
+. Save the content of the folder you have as your storage path on the first phone - you can find the storage path at _Settings → Sleep Noise recording → Storage path_.
+. On the new phone, decide a location for your new storage path.
+. If you copied the whole folder with *sleep-data* folder, copy the whole folder to the chosen location on the new phone.
+. If you copied only the sound files, create folder *sleep-data* in your chosen location, and inside this folder, create a sub-folder *rec*. And copy the files to this *rec* folder.
+. Choose the storage path on the new phone in _Settings → Sleep Noise recording → Storage path_ to *your_chosen_folder* (not to the *your_chosen_folder\sleep-data\rec\* subfolder).
+. Sync the backup file - the sound meta-data will pair with the files copied.
+
+NOTE: The actual sound files should be in *your_chosen_folder\sleep-data\rec\*.

 == Sleep Regularity
-To get maximum of your sleep time, it is crucial to sleep regularly – go to sleep at the same time every day and sleep for a fixed period of time.
+Sleep regularity is a key to healthy sleep - ideally you go to sleep at the same time every day and sleep for the same period of time. You can read about https://www.sciencedirect.com/science/article/abs/pii/S2352721823001687[how sleep regularity affects the speed of you aging].

 === Sleep Regularity Index
-SRI is a metric calculated as the probability of an individual being in the same state (asleep or awake) at any two time points 24 hours apart (range 0–100, with 100 being perfectly regular).
-This index can be used for monitoring your risk of health issues - read about the link  https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10153326/[between SRI and mortality], or the link https://www.nature.com/articles/s41598-017-03171-4[between SRI and academic performance].
