4 Things Your Blood Type Says About Your Health
The human species is divided into four blood groups: O, A, B, and AB. The reasons for these differences are thought to have an evolutionary basis. Scientific studies are providing information on how blood groups affect health in the human population. This data can help people understand how their physical makeup affects their health and what they can do to maximize their ability to resist disease.
1- Blood Type Affects How You Deal With Stress Certain blood types are associated with hormones in the body that are related to stress. For example, people with type A blood tend to have higher levels of cortisol in their blood, a hormone known to be associated with higher stress conditions. People who have type A blood benefit from calming exercise routines, such as tai chi or yoga, which reduces this stress hormone. Studies also indicate that individuals with type O may have better tolerance to stressful situations, but they may have difficulty clearing their bodies of stress hormones. These people will benefit from vigorous physical activity that burns off stress more quickly. Those with type B can benefit from yoga and other mild exercise routines. Individuals with AB blood require a well-rounded stress relieving routine.
2- Blood Type Can Affect Gastrointestinal Health The human digestive system normally contains a variety of friendly bacteria that aids in healthy digestion. However, studies find that certain blood types may contain more of these protective bacteria than other types. Those with type B blood are found to have up to 50,000 times more of these beneficial bacteria in their guts than those with type O and A. Individuals with type O blood who may have a particular vulnerability to intestinal infection should ensure that they consume foods that increase digestive health.
3- Blood Type Is Linked To Memory Problems A recent study published in the September 2014 issue of Neurology, the medical journal of the American Academy of Neurology, finds that individuals with type AB blood may be particularly susceptible to memory problems as they age. Because blood type has also been linked to obesity, diabetes and other conditions that affect cardiovascular health, it can also affect blood flow to the brain that can cause problems with memory as the individual ages. As an example, a study from Harvard shows that those with AB blood type have 23 percent increase in the chance of cardiovascular disease than those with type O blood. Individuals with type AB blood should ensure that they eat a heart healthy diet that promotes good circulation throughout the body, to ensure healthy brain function.
4- Blood Type Can Affect Fertility A study from Yale University School of Medicine links lowered ovarian reserve in women with type O blood. Ovarian reserve is a term used for the amount of eggs and the number of sufficient quality to produce a pregnancy, a condition that can affect the success of fertility treatment. A decrease in ovarian reserve is common in women in their 30s and 40s, but women with type O blood show this reduction at an earlier age.
