Buy a hat to cover your ears because the ears are very important. If your ears are warm, the whole body is better. Sometimes I have headaches because my ears are cold. If you have long hair, it's better. If it's too cold, bring two sleeping bags: one to sleep in, and one to cover outside. Because the sleeping bag is very insulated, and insulation is good; buy a good one. Or sometimes a simple one also helps, because the cover of the sleeping bag is meant for insulation. So if it's very hot, you can put the sleeping bag on top of your tent and open the window. Just leave the screen door open. When you sleep inside, at midday it's still very cool. And if it's very cold, you can spread the sleeping bag over the top of your tent to make it more insulated. It's much better. And cover your ears with that Loving Hat, and cover with a blanket. You can also cover your head like this ,and then sleep inside a sleeping bag. This makes a big, big difference.

　　建议你们买顶可以遮盖住耳朵的帽子，因为耳朵很重要，如果耳朵暖和的话，整个身体就会舒服多了。有时我会因为耳朵冷而引起头痛，如果你留的是长头发，就会好一些。假如天气太冷，就带两个睡袋来，睡在其中一个里面，另一个则盖在上面。因为睡袋的隔温性能很好，所以有很好的保暖效果；买的时候要买好一点的睡袋。

　　不过，有时候简便型的睡袋也有用处，因为睡袋外层是专门用来隔温的，当天气很热的时候，不妨可以将睡袋铺在外帐上面，打开外帐的通风口，只需拉上内帐的纱门，那么即使是中午睡在帐篷里，里面也会非常凉爽。如果天气很冷，也可以将睡袋铺在外帐上隔离寒气，就会感觉暖和多了。还有，可以用爱心帽盖住耳朵，再用毛毯盖起来。你们也可以像这样盖住头，然后再睡在睡袋里头，这样感觉完全不一样。

　　And wrap another blanket like this, inside your sleeping bag, on top of your body. That also makes a big difference. I just cover with this a little bit and I feel complete, immediate relief for the ears, and it feels very warm. It really makes a big difference that you cover your ears. The women can put their hair down and still cover their ears; the men can cover with a hat. Because this is where you feel a headache. And sometimes the cold wind goes through your ears. Your ears are very sensitive inside. And they have a lot of nerves connected with the whole body and the head. So if your ears get too cold, it gives you a headache. And you have a cold and flu and everything like that. So it is better to keep your ears warm.

　　或者在睡袋里用一条毛毯将身体包裹起来，也会有很好的保暖效果。我只盖一会儿，整个身体就温暖起来，耳朵马上就舒服多了，感觉好暖和！

　　耳朵盖起来以后真的感觉很不一样。女孩可以将头发放下来盖住耳朵，男孩可以戴帽子盖住。因为耳朵是会引发头痛的部位，有时冷风灌进耳朵里，而我们的耳朵里面非常敏感，有很多神经连结到头部和全身，因此，如果耳朵太冷，就会引起头痛，甚至会造成伤风感冒等等症状，所以耳朵最好要保持温暖。
