Rest
Constant sleep can help the body to heal faster. The importance of rest and sleep cannot be overemphasized. When you sleep, your white blood cells act up and attack viruses and bacteria; also, your brain stimulates hormones that encourage tissue growth when you sleep.
Regarding sinus pressure, try to avoid over-stimulating beverages when you want to sleep, and you should also elevate your head by placing it on a pillow. This would help you breathe more comfortably.
Frequent Exercise
Light exercise can reduce sinus pressure. When you engage in physical activities, there is an increase in blood circulation, which would help relieve congestion and make it easy to breathe. Although it is not easy to exercise when you feel sick, some physical activities can help speed up your recovery.
