The sudden change of weather may affect a lot of people tremendously. Here are just some of the diseases that you might get afflicted with if you are not too careful:
Heat stroke is well known because people who experience extreme weather conditions undergo this condition. It would be best to always be protected at all times by always having cold drinks with you especially if you are going to walk for a long while. Protective clothing will also do a lot.
Chicken pox is also another disease that is common during summer. The heat causes people to break out and since it is highly contagious, a lot of people get it during that time.
Dehydration is also another condition that people normally experience during the summertime. The key to making sure that you do not get dehydrated is to drink a lot of fluids. You might not feel thirsty but listen closely to what your body is telling you. Having a sphygmomanometer might also help since you can monitor your blood pressure. This way, you can tell whether you are starting to have problems or not.
