No major health issues apart from the usual cracking hands which can be painful and a bit debilitating. I used a lot of paper tape and iodine cream. I had a tiny tub of Vaseline, but maybe some hand cream would have been good.
After three days of wet feet and a long road section I had a couple of blisters on my heels. I used Betadine to keep them clean and dry them up a bit after draining and they soon healed.
Little bit of wind burn on my nose (can't have been sunburn as there wasn't enough sun!).
There is no Hygiene section here for a very good reason ;)
