Feeling drowsy, tired, and sluggish when PM2.5 dust levels spike? Here are ways to relieve fatigue during the day to lessen the effects of fine dust particles.
Escaping street dust only to face office air, why still feel drowsy and tired as if you didn’t sleep enough? In fact, PM2.5 dust that sneaks in may be causing your brain to lack oxygen and become inflamed. Thairath Online shares 5 secret tips to "wake up" office workers so they can stay alert and keep working immediately.
PM2.5 dust affects not only the respiratory system but, due to its size being smaller than 2.5 microns, it can enter the bloodstream and trigger systemic inflammation at the cellular level. This causes the heart and lungs to work harder to deliver oxygen throughout the body. When the body expends extra energy fighting foreign particles, we tend to feel sleepy, fatigued, and experience brain fog easily.
On days with high PM2.5 levels, the body dehydrates more easily due to internal inflammation. Drinking ice-cold water stimulates the sympathetic nervous system to stay alert.
If feeling tired from dust exposure, avoid consuming multiple coffees as this can overwork the heart amid pollution. It’s better to drink lemon soda or hot ginger tea to help reduce throat inflammation.
PM2.5 dust causes shallow breathing unconsciously, reducing oxygen supply to the brain. Try the 4-7-8 breathing method.
This technique helps expel trapped carbon dioxide and raises blood oxygen levels, helping a brain fogged by dust to function better again.
Hunching over while working long hours limits lung expansion. In polluted air, this worsens fatigue. Stand up, clasp your hands behind your back, and stretch your chest upward, holding for 15 seconds. This posture opens the chest to take in more filtered air from the office, reducing brain fog.
Peppermint and eucalyptus scents are proven to stimulate the brain best because their menthol content clears airways and eases the discomfort caused by dust accumulation in the nasal passages. Simply dab essential oil on your wrists or inhale from herbal inhalers to feel instantly refreshed.
If all the above methods don’t relieve your brain fatigue, try washing your face with water in the restroom. The coolness refreshes you and signals the brain that "it’s time to wake up."
Besides these 5 daytime fatigue remedies for PM2.5 dust exposure, adjusting some lifestyle habits during high pollution periods can help the body resist and protect itself from PM2.5 to some extent, such as:
Especially fruits and vegetables high in vitamin C—like oranges, guavas, leafy greens—and vitamin E sources such as nuts and seeds. These help reduce inflammation and strengthen immunity because PM2.5 dust generates free radicals in the body that cause inflammation.
When indoors, turn onan air purifierwith a HEPA filter. Nasal irrigation with saline helps reduce dust accumulation in the nasal passages, which can cause breathing difficulties and body fatigue.
On high pollution days, avoid outdoor exercise as this increases dust inhalation into the lungs. If you feel tired during the day, try a short power nap of about 15-20 minutes to rest your brain.
Sleep is the best way to repair the body. During dust crises, aim for 7-8 hours of sleep so your body has the energy to fight pollution the next day.
Fatigue from PM2.5 dust signals that the body is overworking. Proper adjustments in diet, environment, and self-protection not only reduce tiredness but also help prevent serious long-term diseases associated with air pollution.
