Blocks 100% of Light but My Overall Sleep Quality Declined
Reviewed in the United States on October 27, 2019
I purchased 4 of these masks for myself and my family and we have all been using them for the last week. All of us utilize devices (I use an Oura ring my family uses Whoop) to track the quality of our sleep each night and this mask came highly recommended from a well known Podcaster so I thought we would try them and see the impact on our sleep scores.
First impression was that the Mask seemed a bit bulky...much thicker than the cheap satin masks we were used to using (see pictures below...top mask in each photos is a standard mask and the bottom is the Mindfold). However, we all agree that the mask did an AMAZING job at blocking out light. None of us experienced a single ray of light when wearing these masks, even in well lit rooms. It is worth noting that my family all have different sized and shaped heads so I was very surprised that this mask worked for all of us.
None of us found the masks to be very comfortable and all but my youngest found the straps to irritate the top part of the ear that connects to the head. To avoid this, we had to move the strap up higher on the head but it wouldn't stay there and would move back down as the night progressed. To prevent this slippage, we had to make the band fairly tight around the head which worked but was uncomfortable.
The most unusual result of using these masks was a material drop in the quality of sleep that we all experienced every night since using the mask Remember, we use devices to track the quality of sleep (less deep and rem sleep plus an increase in sleep interruptions) so this drop in sleep quality was identified in all of our tracking devices and not just a subjective feeling (per my Oura ring, my sleep scores for the last year have been between 90-100 on a scale from 0-100 and since using the mask, I have not experienced a score greater than 80 - last night's score was 71 - my lowest since I started recording my sleep quality). This result was really surprising given that the mask effectively blocks out 100% of the light No other factors had changed that would impact our sleep so my hypothesis is that the uncomfortableness of the mask (strap and inside foam) ended up disrupting our sleep cycles. Going to play around a bit more with finding ways to increase the comfort of the mask and will post an update on findings.
