IN THIS FOR THE LONG HAUL…

Here's how different parts of our bodies are affected...
Heart "Flying long haul can affect breathing, causing shortness of breath and sometimes chest discomfort," says Dr Jenkins, an advisor to Deep Heat, Deep Freeze and Deep Relief.
"People at highest risk of heart issues on a plane are those who already have cardiovascular disease."
If you have any heart issues, always check with your doctor if it's OK for you to fly, and pack any necessary medication in your hand luggage.
"Dehydration, changing cabin air pressure and low oxygen concentration - modern aircraft are pressurised to an equivalent altitude of 6,000-8,000ft, so you are actually breathing in less oxygen", can all play a part.
On top of that, "sitting in a confined space limits chest movements so you don't breathe as deeply, and increased stress [from flying] can all increase the risk of heart problems", adds Dr Jenkins.
Deep vein thrombosis (DVT) and blood clots are a particular risk for those without heart disease too, for all the same reasons.
"Blood clots can occur for up to one month after flying, so be alert to symptoms such as swollen or painful legs, especially the calf, and breathing difficulties [clots can occur on the lungs too]," adds Dr Jenkins.
To reduce risk, keep well hydrated, don't drink alcohol during your flight, and stretch and move around as much as possible.
Low humidity pressure cause stomach
Stomach A change in humidity can also cause havoc on your stomach.
"Aeroplane cabins have low humidity levels, which can cause dehydration and lead to digestive issues such as constipation and discomfort," says Dr Simon Theobalds, GP at Pall Mall Medical.
"The change in cabin pressure can also cause gas expansion in the stomach, leading to bloating or discomfort. Prolonged sitting during long flights can contribute to sluggish digestion and constipation."
The disruptions to your circadian rhythm, or body clock, from crossing multiple time zones can affect your digestive system too, leading to irregular bowel movements and appetite changes, he adds.
Not to mention that the time zone changes disrupt meal patterns, also "potentially leading to indigestion or stomach discomfort".
Dr Theobalds recommends stay- ing hydrated and choosing light meals, while also moving around the cabin a lot.
