Move
Do 3 sets of 10 air squats during a break. Squats are a nearly unbelievably effective movement for strength, balance, flexibility, and endurance. They make you better at life and you don’t need anything but a couple of square feet of space to do them. If 3 sets of 10 is easy, do 2 sets of 15, or 1 set of 30, or just as many as you can in a minute.
Eat
One day this week, replace sugary drinks with water or unsweetened tea. I’m not a maniac. I know it’s not the same. If you’re craving a Dr. Pepper and I give you a cold, flat, jar of water that’s had old leaves soaking in it, your craving will not be relieved. But although sweetened drinks aren’t at all morally bad, they tend to do more harm than good. Getting in more water is almost all upside.
Sleep
Keep electronics out of the bedroom. That is much easier said than done. But screen use at night, and especially in bed, is linked to poor sleep quality time and again. At least a few nights in a row, try screen-free nights and see what happens (note: it might take 3+ nights of trying this to notice a difference).
Manage
Take 10 deep breaths before responding to a stressful situation. In addition to the ways deep breathing tends to reduce reactivity and support emotional control, taking space lets you think more clearly. It’s the reason your kindergarten teacher told you to count to 10 when you were mad. It helps.
