I am afraid your query is a little puzzling. Are you referring to the sudden feeling of congestion that people often complain of, especially in the region of the neck to the head? This is a symptom of burning head, a symptom that manifests itself when you have been in the sun too long. A burning head is usually an indication that you have had a slight touch of the sun. In addition to feeling as if your head will burst, you may also experience some amount of nausea and waves of heat moving towards your head. You will also experience a sensation whereby you will think your head is larger than it ever was.
The best solution for a burning head is to use raw onion. Peel and grate a large onion. Now squeeze it to extract the juice. Apply this to the soles of your feet and rub it into your hair. Lie down after you have done this. Drinking cold fruit juices will help you too. Lemon juice, with sugar and salt added to it is also very beneficial to people suffering from a ‘burning head'. Lie down in a darkened room, with all the curtains drawn. Avoid eating any rich food items. Instead stick to drinking fruit juices and buttermilk.
