I have this issue it lowers my blood sugar. I just eat a snack before I take a shower I like to take em really hot. I'm a gestational diabetic though so I have to eat every two hours regardless or i get light headed and shaky
It Seems To Happen To Me Mostly If I Haven't Eaten Before I Showered I Get Lightheaded and Tingly or Even When I'm Getting Dressed and Been Standing For a While I'll Get That Same Feeling
