We all want to be healthier. The simple way to do that is to eat your fruits and vegetables, hit the gym, drink enough water, you know the drill.

But though we may feel better after practicing these types of health tactics, we don’t know for sure what’s going on deep in the depths of our health souls until we go to a doctor and they perform all those tests.

But let’s face it—we don’t always have the time or money to be getting check-ups every so often at the doc. So we wondered—is there are anything we can do from the comfort of our home that can test for our health?

Actually, there is. These self “tests” as simple, easy, quick, and don’t cost a thing—they’ll give you insight into what’s going on inside, and best of all, you can do them in just a few minutes flat, from anywhere in the world.

Start checking your health now with these simple tests:

1. The anemia test

   Anemia causes fatigue, dizziness, lightheadedness, a fast heartbeat and trouble breathing. It results from a lacking of red blood cells, which can cause reduced oxygen flow to the body’s organs. If you think you may be anemic, stand in front of a mirror and press on your lower eyelid to lower it down. Typically, the color of your under-eye ball should be pink—if it’s pale pink or of a yellow tint (and you have those other symptoms) you may be anemic.

2. The carpal tunnel test

   Carpal tunnel syndrome causes pain, tingling and numbness in the hand and/or arm, caused by a pinched nerve in the wrist—it’s pretty common in office workers, e.g., people who type all day. If you’re experiencing this, lift your hands up so that your forearms are parallel to your face. Then lower the tips of your fingertips to touch the base of the palm. If this feels good, you’re good. If this is causing you pain or numbness, you may have carpal tunnel.

3. The hormonal imbalance test

   Make sure your hair is clean and dry. Then separate a small section of your hair and pull on it gently. If you come out with a few loose stands of hair, then you’re healthy. A clump of hair, and you may be experiencing some sort of hormonal imbalance or nutrient deficiency, so it doesn’t hurt to get it checked out by a doctor.

4. The heart and lung disease test

   Hold out both your hands in front of you and create a letter J with both (your left hand will make a backwards J. Then lower your pointer fingers to touch one another. Look closely—if you see a tiny diamond shape formed between these two fingers, you have healthy heart and vessels. If they lay flat against each other, you may have nail clubbing, which can indicate cardiovascular diseases, lung problems, and gastrointestinal issues. See a doctor if this is the case.

5. The stroke and dementia test

   Reserve a bit of time for this one. Stand up straight and lift one leg up so that your hip is parallel to the floor. Then start a timer on your phone—can you stand like this comfortably for 20 or so minutes? If you’re having trouble balancing, the vessels in your brain may be doing something wonky. You may want to check in with your doctor just in case.

6. The diabetes test

   Diabetes is definitely one you’ll need to get your doctor’s full diagnosis for, but if you think you may be developing it or have it, ask a loved one to help you with this self-test: Grab a pencil with an eraser and have helper touch your foot and toes with the sharp end of the pencil and with the eraser, one after the other. People with nerve damage on their feet might not feel a difference—and this type of low sensitivity might mean diabetes.

7. The artery test

   Lay down on the floor and lift your feet up at a 45° angle, keeping them forward like that for a couple of minutes. Then take a look at your feet—what’s the color? Are they paler than usual? You may be experiencing issues with your blood circulation, which may be a sign of peripheral artery disease (PAD). See a doctor if you also have symptoms such as numbness or pain.
