Common Summer Illnesses That You Should Watch Out For

Since Japan's summer is hot and extremely humid, it is easy to get various diseases from loss of appetite, lifestyle problems, heatstroke, infections etc.

Heatstroke and Level of Symptoms

Level1:Dehydration

It happens when the body's moisture is lost through sweating and it cannot be replenished. It can also cause loss of appetite. In addition, loss of electrolytes from bones and muscles can also result in leg tightness and numbness.

Level 2:Heat exhaustion

As a result of the balance of water and salt in the body is broken and the body temperature regulation function doesn’t work, symptoms such as headache, nausea, dizziness, malaise, severe cramps and unconsciousness can occur.

Level 3:Heatstroke

Since ability to regulate body temperature cannot keep up, it results in hyperthermia above 40℃, causing paralysis of the central thermoregulatory functions of the brain and heatstroke to occur. It can also cause unconsciousness or shock. Heatstroke is the most dangerous, and it is not uncommon to die.
