Thanks for the good night sleep tips, I need to improve on point 2. I was wondering about the impact of the evening exercise on the sleep. Do you think that intense exercise late in the evening can negatively affect ability to fall asleep and if yes, what is the good time to stop exercising before going to bed. Or maybe opposite you are so tired that you just go down in seconds? Tired or wired?? Also, would listening to relaxing music or sounds of nature as a part of sleep routine be a good idea or just unnecessary destruction? And yes, I need to have my windows opened all year around (except crazy hot summer nights) to keep the bedroom cool and with fresh air, otherwise no sleep for me.
