Reverse Altitude Sickness is not seen in every person. The symptoms and effects of reverse altitude vary from person to person. A person who has a record of past sickness relating to altitude sickness often develop this sickness quickly after a latitude drop of about 2,500 meters.

People who have a habit of drinking alcohol and lots of coffee are also prone to reverse altitude sickness. Alcohol and coffee slow the flow of oxygen of your tissues to the heart and thus increases the chances of altitude sickness.

Dangers of Reverse Altitude Sickness

Like High altitude sickness, Reverse altitude sickness is very dangerous and can be life-threatening in its severe form. Reverse altitude sickness increases the blood pressure in the absence of oxygen in the blood. The rapid blood pressure in severity leads to leakage from the vessels to the brain and lungs. This is called Edema and is very serious and can lead to death without medical attention.

The best way to prevent reverse altitude sickness it to let the body adjust. You must pace your descent to avoid any discomforts. Overexertion and extreme physical stress to your body hype the symptoms of altitude sickness, so take it easy and climb down taking regular breaks. Also, keep yourself hydrated. Drink on average 4 to 6 hours of water per day to replenish water lost by the body in the form of sweat and heat.

Refrain from alcohol, smoking, and coffee the prior day when transitioning from high altitude places.

You can contact your doctor and carry medication to prevent altitude sickness. Acetazolamide and Dexamethasone help to prevent altitude sickness by keeping a steady flow of blood and assist the red blood cells to take oxygen to all parts of the body.

Nepalese people use Garlic and Cloves to treat minor symptoms of altitude sickness. They help in the flow of blood inside the blood vessels by thinning the blood. Make sure to carry clove and garlic; they can be convenient to treat mild symptoms when traversing the Himalayan regions of Nepal.

How to Acclimate Better

There are several ways that can help you to acclimate better and avoid the trouble of altitude sickness. The actual cause of altitude sickness differs from person to person so as the remedies. If one activity eases one’s reverse altitude sickness, that may not apply to another person. Some ways you can use to acclimate better to your surroundings are:

    • Drink Lots of Water: Your body loses water and sodium when adjusting to altitude changes and leads to dehydration. Exercising makes you lose water even quicker so drink as much water as you can. Water provides the added oxygen to your blood cells that you need to acclimate better in high altitude changes.
    • Moderate your physical exercise: Over-exertion and fatigue is also a major factor for reverse altitude sickness. If you try to descent low altitudes even when fatigued, you will develop altitude sickness symptoms. So, moderate you daily physical exercise, mainly when trekking to acclimate better to lower altitudes. A moderate physical exercise puts less strain on your body to perform at altitude differences and prevents altitude sickness.
    • Get a good night sleep: A sound sleep is the most natural way to acclimate better. The body goes through various adjustments when you are sleeping. The body adjusts as much it can when you are resting. If you don’t give enough sleep for the body to adapt to altitude changes, then you won’t acclimate as much as you should. So, take a good nights sleep and acclimate to prevent future reverse altitude difficulties.
  • Control your alcohol intake
  • Slow and gradual descend
  • Eat High Calorie and Low Salt diet
