When I get hot my face gets really red! How do I keep that from happening?
You may not be able to prevent it from happening. Try to cool off quickly - drink iced fluids, go to a cooler room, think calm thoughts like laying on the beach listening to the waves or staring into a campfire.
You are required to determine the best temperatures that suit you initially. Consider seeking the assistance of a skilled doctor to get the best remedies that heal this effect completely.
just let it be and don't worry about what other people say
Same thing happens to me and my friend!!! So I guess that means it happens to a lot of people so don't worry about it :)
