There's no point adding stress to your already stressed-out upper respiratory system, and that's what the change in air pressure will do. Flying with cold or flu congestion can temporarily damage your eardrums as a result of pressure changes during takeoff and landing. If you must fly, use a decongestant and carry a nasal spray with you to use just before takeoff and landing. Chewing gum and swallowing frequently can also help relieve pressure.
Sepel recommends warm water with lemons in the morning: “One of my top tips is warm lemon water. I enjoy this hydration boost every morning to prepare my body for digestion and detoxification. Probiotics are also essential, whether it’s in supplement form or probiotic-rich foods like fermented vegetables, tempeh and organic yoghurt. I also encourage my clients to cut gluten for a few weeks as it causes bloating and digestive discomfort for so many,” she said.
To calm a nagging cough that keeps you awake at night, take 2 teaspoons of honey (1 to 2 teaspoons for kids; don't give to children younger than 1), along with 500 mg of Ester C 30 minutes before bed. The vitamin C (nonacidic Ester type won't upset stomachs) boosts the immune system in the early stages of your cough. Research shows that honey works better than either a cough suppressant or no treatment at all for relieving children's nocturnal cough and promoting sleep.
Mint has been used for hundreds of years as a health remedy. Peppermint oil might help with irritable bowel syndrome -- a long-term condition that can cause cramps, bloating, gas, diarrhea, and constipation -- and it may be good for headaches as well. More studies are needed to see how much it helps and why. People use the leaf for other conditions, too, but there’s very little evidence it helps with any of them.
