What is the difference between heatstroke and sunstroke?

Both heat and sunstroke usually occur in warm seasons and are associated with a violation of the body’s thermoregulation. However, sunstroke is directly related to excessive exposure to sunlight. Excessive exposure to solar radiation and excessive heating lead to the fact that people have fever, dizziness, nausea, etc. Heat stroke is not specifically associated with exposure to sunlight. It occurs due to special overheating of the body (for example, when a person puts on too warm clothes in the heat).
