Could a few minutes of morning light actually improve your eyesight? 🤯 Andrew Huberman explains research around morning light exposure, including a study where people over 40 looked at red light for only 3–4 minutes each morning and saw improvements in vision... He says morning light may support hormones like testosterone and oestrogen, with red light being just one way to get that exposure. Simply stepping outside into natural sunlight can offer similar benefits. Are we underestimating how important morning light really is? #sleep #redlight
