Hyigene.

Stay germ free by bringing antibacterial wipes. Most planes have a quick turnaround so cleaners do a basic job. Wipe all the hard surfaces around your seat including tray table, lever, remote control, arm rests and seatbelt buckle.

The seat-back pocket is also a hub for germs with many passengers plunging their personal belongings deep into the pocket as soon as they board. Make sure you're organised with an essential flight pouch to hand with everything you'll need so you can avoid using the back seat pocket entirely!

Vitamins On The Go.

Natural remedies work wonders on a flight for any travel ailments. Vitamin C will help the body build immunity to new germs, vitamin D supplements help form natural body rhythms and combat jet lag. Whilst a melatonin supplement aids sleep by increasing your bodies natural melatonin. Cinnamon, cardamom and water are best for digestion.

Hydration.

Stay hydrated - drink plenty of water and avoid excessive amounts of alcohol. Regularly apply moisturiser and lip balm in order to help stay hydrated. This will not only help you sleep better on a long-haul flight, but it keeps blood flowing too, which will help avoid DVT (deep vein thrombosis) and hydrate your skin.

Sleep.

To sleep well and feel refreshed, eat light meals and drink plenty of water. Avoid products with lots of sugar, caffeine, or alcohol. Sleep deprivation causes your body to slow down its production of antibodies that fight infection. There are lots of germs on planes, so it is important to keep your immune system energised and ready to fight unwanted infections.

Movement.

Avoid DVT on a long flight: do some calf exercises every half hour - raise your heels, keeping your toes in the floor, then bring them down and repeat ten times. Take occasional walks up the aisle when possible to boost blood circulation. Wear elasticated compression socks. They work by putting gentle pressure on your legs and ankles to help blood flow.
