Health warnings often show up with ⚠️ to flag risks or reminders. Use ⚠️🚭 when telling someone to quit smoking or 🧴⚠️ when reminding about sanitizer. 🍔⚠️❌ fits well in debates about junk food, while 🥗⚠️✅ can highlight better choices. These combos work in gym group chats, nutrition posts, or even casual texts when you want to warn without sounding too preachy.
