Have you found yourself constantly catching colds lately, dealing with recurrent mouth sores, or facing unwelcome visitors like herpes zoster whenever you feel run-down? Are you worried because your whole body feels chilly and achy, and your allergies seem worse than before? If you find yourself groaning with fatigue every day, this may not be simple tiredness, but an essential warning signal sent by your body.

Do you find yourself holding your smartphone and staying awake until the early hours of the morning? Are you startled each day by loose hair on your pillow, increasingly brittle strands, or sudden gray hair in the mirror? Sleepless nights may quietly impair hair health. If you are concerned about your hair losing its vitality, consider how sleep plays a direct role.
