Simple Health Checks You Can Do at Home

Heart and lung disease test

Make your fingers in the shape of an upside down letter J and put your nails against one another. Do you see a tiny diamond between them? Great, this means that your heart and vessels are perfectly healthy.If there is no space between your fingernails, it may be a sign of nail clubbing. The fact that fingers become thicker means that the blood doesn’t have enough oxygen. Oxygen deficiency can be caused by multiple reasons. For example, cardiovascular diseases, lung problems, and gastrointestinal issues.
