Why you got headache in staying long a closed room with air conditioner?

Staying in a closed room with air conditioning for an extended period can lead to headaches due to several factors:

Lack of Fresh Air:

- Air conditioners recirculate the air within the room, which reduces the oxygen levels. The decrease in oxygen can cause headaches, fatigue, and difficulty concentrating.

Dry Air:

- Air conditioning can remove moisture from the air, making it dry. Dry air can irritate the nasal passages and throat, leading to headaches.

Temperature Changes:

- Frequent temperature changes between the air-conditioned room and the outside environment can cause headaches.

Noise:

- The humming sound of the air conditioner can be disruptive and contribute to headaches for some individuals.

Chemical Sensitivity:

- Some individuals may be sensitive to the chemicals used in air conditioners, such as refrigerants or cleaning agents. These chemicals can trigger headaches in susceptible individuals.

Poor Ventilation:

- Inadequate ventilation in a closed room with an air conditioner can trap pollutants, such as dust, pollen, and allergens. These pollutants can irritate the respiratory system and cause headaches.

Dehydration:

- Air conditioning can contribute to dehydration, especially when the humidity levels are low. Dehydration can lead to headaches and fatigue.

To mitigate the risk of headaches in a closed room with an air conditioner, ensure proper ventilation, maintain adequate humidity levels, take regular breaks from the air conditioning, and stay hydrated. If you experience persistent headaches, consult a healthcare professional to determine the underlying cause.
