How long does Freon sickness last?

Mild symptoms of refrigerant exposure—such as a slight headache, dizziness, lightheadedness, or throat irritation caused by breathing minor traces of gas in a poorly ventilated space—typically begin to fade and go away completely within minutes to a few hours once you remove yourself from the contaminated environment and breathe fresh outdoor air. The human body metabolizes and clears minor gas exposure rapidly once oxygen levels return to normal. However, severe refrigerant poisoning resulting from prolonged, high-concentration inhalation in an enclosed space can cause chemical asphyxiation, cardiac arrhythmias, or frostbite burns to the respiratory tract, requiring emergency medical intervention, oxygen therapy, and hospitalization where recovery can take days. You can troubleshoot by seeking fresh air immediately. You can verify recovery when dizziness and breathing difficulties subside.
