The idea that staying under the sun can cause malaria is a popular myth, but it's not scientifically accurate. Malaria is not caused by heat, sun exposure, or sweating—it is caused by a parasite transmitted through the bite of an infected female Anopheles mosquito.
What Actually Causes Malaria?
Malaria is caused by a Plasmodium parasite, transmitted through a mosquito bite. Once in the body, the parasite multiplies in the liver and infects red blood cells.
Common Symptoms of Malaria:
Fever and chills, headache, body aches, sweating, weakness, and vomiting in some cases.
How to Actually Prevent Malaria:
- Use mosquito nets, especially at night
- Apply insect repellent on exposed skin
- Drain stagnant water where mosquitoes breed
- Take preventive antimalarial medication when advised (especially during pregnancy)
Bottom Line
Staying under the sun does not cause malaria. The disease is caused by mosquito bites, not heat or sunshine.
