Marina: Hi Dr Cabral, I'm after some help for my sleep. I fall asleep easily around 9-9:30 but wake up 2-3am unable to fall asleep. I do know that my cortisol is super high all day. I have cut back on intense exercise, 1 espresso a day around 10am, meditation 15-20 min a day, breathing 5-10 min a day. I'm not noticing positive effects. I'm stuck in sympathetic mode. Any tips? Thank you

Meghan: Hey Dr C, firstly sharing in total gratitude for you, your passion, dedication and genuine care for your community. Thank you for all you do. My question today that I couldn't find when searched was about grounding bed sheets. Grounding is a hot topic but in modern lifestyle it's always easy to spend time barefoot in the grass each day and it makes sense to me to be able to be grounded for the duration of sleep to advance healing (so long as they are a low emf product of course). There are different types some you plug in and others you don't. Wanted to get your thoughts on whether there is any real science behind grounding bed sheets? I have also seen the grounding mats for office use that may be helpful as well. Thanks again. Keep on shining your light.

Anonymous: Hello Dr. Cabral. Could you please detail what is the best workout for women with PCOS and the best time of the day to exercise to improve insulin sensitivity and reduce cortisol, inflammation and testosterone? I am 29 and have lean PCOS. I heard that I should avoid exercise that increases my cortisol, for example, HIIT/Crossfit/anything that increases my heart rate too much. My PCP also recommended I stop lifting heavy weights, she said this could increase my testosterone. Could I keep lifting heavy just as long as I slow down and give myself enough time to keep my heart rate low and steady? I don't want to give up my "gains"! I don't need crazy exercise classes, but I don't want to restrict myself to only do yoga, walking, or very light weight training. Please help! Thank you!

Carol Ann: Thank you for helping us with your podcasts. I have learned so much. I would like your advice as to which blue light blocking filters for TV to buy. They are widely available now, even on Amazon, but I need help sorting through which really helps, for their value. I am working on improving sleep with blue light blocking, as blue light can prevent melatonin from being produced. Thank you

Carol Ann: Hi Dr C, Thank you for teaching me health care info with your podcasts. You have made a real impact. I have a breast cancer screening question. For many years, mammograms were recommended, where radiation is used to make an image to screen for breast tumors. Now, there's a movement to use sonograms to screen the breasts instead. This seems like a safer plan, but I can't find any studies comparing these options. One company that uses this is HerScan. Is this reasonable or a bad plan?
