Travel Wisdom friend Andrew Miles of Botanical Biohacking talks about how to keep healthy while travelling. Especially long flights can be quite harmful to your sleep, your gut microbiome, and ultimately your health. He infuses some Eastern wisdom explained in a Western way so that you don't become more unhealthy after travelling. The key is to train your body and eat as little as possible before travelling. Then when you arrive you need to get on the same eating schedule (breakfast, lunch, dinner) as the local population as soon as possible. He also notes that there are more important things than health including maintaining strong social contacts.
