Autumn is upon us in the northern hemisphere, and parts of the southern ought to still be pretty chilly. If you start getting cold, try tucking in your shirt. If you’re wearing long pants and long socks, you can even tuck your pants into your socks, and this one’s a big help too.

Why YSK: this one tip can save you a ton of money over your lifetime by lowering the threshold for when you need to put the heat on in your house, and it can make you feel more comfortable in the colder seasons. Wearing thicker clothes and layering helps, but there’s only so many layers you can comfortably wear and clothes can only be so thick before you probably don’t feel comfortable wearing them inside. If you’re out and about, it might not be realistic or convenient to throw on another layer. This has become my first line of defense when I start getting cold. You should feel noticeably warmer within minutes.

Additional tip: if you have two shirts on, you can tuck the overshirt into your pants and the undershirt into your underpants to create a pocket of warm air that’s way more insulating than if you tucked them into the same layer.

Edit: I know this is “common sense”, but you’d be shocked at how many people either don’t know about this or forget to use it.
