Tempted to tipple in flight? Science has an answer. Also, the best summertime exercise.

This week, we go airborne—and consider the drinks cart. Plus, is swimming the best way to cool off? What other exercises—from lifting weights to e-bikes—offer superior health benefits? And what does this new database tell us about space health as more civilian missions launch?

Is drinking in flight a good idea?

Up 30,000-some feet in the skies, you’re already taking in extra oxygen, dehydrating faster, a little on edge. Oh, here comes the drink cart. Water, juice, something stronger? Would a beer, wine, or harder liquor make things better—or worse? The science is getting clearer.

Need to cool off? This is perfect.

Swimming may be the best exercise. If sweltering temperatures push you into the pool, you could be strengthening your muscles, reducing inflammation, and boosting your mental health. Let’s go!

How spaceflight affects a human body

We know spaceflight doesn’t account for everyone. What about people with different backgrounds and medical histories? A new study explores this question with data from the four civilian crew members of SpaceX’s Inspiration4. What did they find?
