"Ice".... for The First Aid
Beside to make fresh drink, ice also can use for giving first aid. There is a common function of ice; the cool water makes vein narrowly. So, when you get an accident and having lump, you can put ice on it. And it will make you feel better.
When we will do outdoor activities, for example outbound, hiking, climbing, and camping, please bring ice in the small icebox. Ice can treat the insect biting, like bees, scorpions, and centipede. There will an itch because biting of insect. Don’t scratch it because it will make spread of the poison. By giving ice on that biting place, the poison will still there and will not spread in all of our body. But, don’t put ice to long (maximum 20 minutes) on it. Do it continuously to prevent the lump.
If there is no ice, you can use freeze vegetable. Wrap it up with towel to avoid the direct context with skin. It will decrease the effect that we don’t want it happened.
