Heat disorders have become increasingly common in recent years.
In order to enjoy the summer months safely, everyone should be aware of the danger that the summer heat poses and the measures they can take to protect themselves.

Heat disorders have been in the news more frequently in recent years due to climate changes caused by global warming. Heat disorders can occur not only when someone is working or exercising strenuously in direct sunlight in the summer, but also in the rainy season at the beginning of the summer, when people's bodies have not yet adjusted to the heat. Heat disorders can occur not only outdoors, but also in hot, humid indoor environments. When the symptoms are severe, heat disorders can be life-threatening, but can be prevented if you know what to do. Everyone should be aware of the danger of heat disorders and the measures they can take to protect themselves.
