Clinical trial shows that the use of Vitamin D supplement improves sleep quality
If anyone is struggling with sleep, I highly recommend episode 1-3 of the Huberman Lab podcast (https://www.youtube.com/watch?v=H-XfCl-HpRM), it has literally changed my life. Dr. Huberman is a Neurobiologist at Stanford and explains the science of sleep vs just telling you to not look at bright screens at night.I struggled with sleeping for 20+ years, now I easily wake up early.The biggest game changer: Sunlight in your eyes within 30 minutes of waking up. Try morning walks for 1 week (without sunglasses) and your life will be changed.
