I get around 7 hours during the week and around 8 on weekends. I find the 7 hours sufficient to be 100% functioning during the day.
I never take a nap (unless dozing off during the 6 pm news counts)
I do not take any sleep aid medication (prescription or OTC), nor any herbal supplements. I have a ceiling fan on for air circulation, and I have a “white noise” machine to reduce ambient noise.
I practice yoga twice a week in the evenings; days that I don’t practice yoga I try to set aside 20-30 minutes in the late evening to meditate. I find these practices relaxing, and therefore I’m not stressed by “brain chatter” prior to turning in for the evening. If I don’t get the meditation in, once in bed I will practice deep mindful breathing (pranayama) until I drift off. I very seldom have any problem falling asleep and never have disturbing dreams that awaken me.
