With all the hype about how great the weighted blanket can help insomnia, I got myself one to see if it can help me to sleep better. First of all, the blanket is heavy. It has a soft cotton duvet with zipper outside. I think it weights around 15 lbs as described. I read somewhere that you need to chose the right weight of the blanket in order for it to work, which is 10% of your weight. So I am about 140lbs, and the 15 lbs blanket is right for me. To be honest, for the first couple days using it, I do not like it at all because it’s so heavy, so every time I turn, I feel like I have to lift the blanket up to turn. Secondly, it’s not breathable so that it makes me sweat a lot in hot days. However, after more than a month using it, I think I get used to it and it actually helps me sleep better. It did not help me to fall asleep, but to help me sleep deeper and stay in sleep longer. And as the weather is getting colder, it now can keep me warm at night because I feel it traps all my body heat inside the blanket. If the blanket can be used in warmer weather, it would have been perfect.
