8 Health Checks You Can Do at Home

Last update: 28 May, 2020

There are several health checks that you can do at home to check on your vision, food tolerance, digestive health, and many other aspects that can indicate that something is going on with your body.

If you do these health checks frequently, it can help you keep an eye on your health. They’ll tell you whether you maybe need to go and see a specialist. Would you like to learn how to do these?

Health checks: taste

For this test you’ll need a little blue food coloring, which you’ll apply to the tongue using a little cotton. You’re then going to observe the results with a magnifying glass. You need to count the number of taste buds close to the front part of the tongue.

If you count 20 or more blue points then you have a good sense of taste and you could be known as a “supertaster“. According to some articles this isn’t good. A “supertaster” can be associated with a higher risk for certain types of cancer.

Some vegetables like broccoli and cabbage have bitter components that help protect against cancer, but these foods can be really unsavory for a supertaster. Basically, the correlation between being a supertaster and having a higher risk of cancer is due to the sensitivity to vegetables, which are high in cancer-fighting antioxidants and vitamins.

Liquid retention

A hand with liquid retention.

To see if you are retaining liquids, press downwards firmly with your thumb in three or four places on the upper and lower parts of the legs. If the area you press stays white for a couple seconds after you remove your thumb, then you are retaining fluids.

You can tell just by looking if your knees and ankles are swollen. In this case, it is recommended to eat less salt in foods and eliminate processed foods from your diet. It is also good to drink more water.


A lack of iron in the diet can cause anemia. To test whether or not you suffer from anemia, extend your hand outwards with your palm face up and push your fingers back.

If, after a few seconds, the hand looks paler, especially the deep lines, then this may be a problem. It would be a good idea to talk to your doctor to confirm the diagnosis. If you are suffering from anemia, then eating red meat and leafy greens can help.

Food tolerance

Some baking soda and some water.

Take a spoonful of baking soda, and mix it with a glass of water and drink it. If you burp immediately afterwards, then that is a good sign. Putting an alkaline substance into the stomach creates gas.

If you don’t burp, it can be a sign that the levels of stomach acid are low and you aren’t absorbing all of the nutrients in your food.


If you want to test your vision, walk 20 full steps back from a parked car. Then look at the license plate. Can you read the numbers clearly? If you notice some distortion or blurriness, then it’s a sign that something isn’t right. It’s best to go and see a specialist.


If you want to test whether or not your cholesterol levels are high, look at the skin above and below your eyes. Are there any yellow spots? These are fat deposits that indicate high cholesterol.

If this occurs, then it’s best to go and see a doctor to take the necessary measures. These little balls of fat only show up when cholesterol is very high for an extended period of time.

Digestive health

A person drinking milk.

Many times, when certain types of foods are digested, you can immediately feel full, bloated, or heavy. If you want to know if this is due to a food intolerance do the following test:

Before eating a food that upsets your stomach, take your pulse. Afterwards, eat a medium to large-sized portion of this food, and then take your pulse again. If you notice that it has increased more than 10 beats per minute, then it is likely due to a food allergy.

Lung function

In the last of our health checks we’ll look at your lungs. If you want to test how your lungs are working, then stand about 12 inches away from a burning candle and exhale with your mouth open. Do you notice a strange sound?

If this occurs then it can be a warning sign of asthma, especially if you tend to cough at night. If you don’t have these symptoms, but feel that your lungs aren’t as flexible as they should be, it’s possible that you aren’t in good physical shape.
