Sun stroke symptoms the next day

Headache, marked tiredness, dizziness, thirst, nausea, muscle cramps, and difficulty concentrating can follow significant heat exposure. Ongoing confusion, fainting, unusual behaviour, trouble speaking, weakness on one side, or numbness are more concerning because heat illness can overlap with a neurological emergency. A stroke is a separate condition, and a sudden new neurological change should not be explained away as sun exposure. Risk can be higher when dehydration, heart rhythm problems, high blood pressure, or diabetes are present.

Stay in a cool indoor place and avoid exercise, direct sun, alcohol, and heavy meals while symptoms remain. Sip fluids if you are awake, able to swallow, and not repeatedly vomiting; an oral rehydration drink may help replace fluid and salts. Use light clothing and gentle cooling. Do not drive if dizzy, confused, or faint. Arrange a GP Consultation if symptoms have not clearly improved after cooling and rest, or if you need help reviewing medicines and underlying conditions.

Call emergency services for confusion, collapse, a seizure, severe breathing difficulty, chest pain, a very high body temperature, or new facial drooping, arm weakness, speech difficulty, or one-sided numbness. Seek prompt medical assessment when vomiting prevents drinking, dizziness persists, urine becomes very dark or scarce, or the person is becoming less alert. Keep the person cool while help is arranged and do not give drinks to someone who is drowsy or unable to swallow.

Ask whether the symptoms fit heat illness or another problem, whether blood tests or an examination are needed, and when normal activity is safe. Mention the time spent in heat, fluid intake, vomiting, medicines, and any previous episodes.
