Chukhung acclimitization

I heard from Peter last night. He's now up in Chukhung (15,500 feet). He'll spend a few days here, climbing higher during the day and coming back to this level to sleep. He says he's sleeping well, which is awesome. I feel a bit like a mother hen when I hear from him, asking about his sleep and heath. 

His room:

His happy face:

He was able to sync his watch so I could see the data. I find it so fascinating.

Oxygen level vs. altitude. 

Resting heart rate: 

You'll notice on Wednesday last week he had improvements on both charts. That was his third day at that elevation. Since then, he's been climbing higher. The general hope is that time at each altitude gives your body to recover. (And, I'll point out that I have a Bachelor's degree in English, so I am 100% qualified to analyze health data from a random running watch. [Insert winky emoji here. Is it appropriate to use emojis on a blog?])

If you're interested in what the area looks like, here's a random video I found from a guy who trekked in the area. The peak he climbs is the one Peter is planning to climb today. I appreciate the descriptor of "crackin'" for the mountain view!
