You can slow the rate of aging by controlling the levels of certain hormones in your body. As people age the levels of testosterone in men and estrogen in women decline drastically and this increases the rate of aging. Testosterone and estrogen are the primary sex hormones and they decline at a rate of 1% each year after you reach your mid-thirties. For both men and women, having low levels of their primary sex hormone can negatively affect their quality of life. Men can develop problems like erectile dysfunction and lower libido, while women can experience disturbed sleep, fatigue and difficulty concentrating. Additionally, women can suffer from mood swings and skin wrinkling, which can be pretty frustrating. Low sex hormones can not only affect your quality of life but also your health. Since both testosterone and estrogen play an important role in maintaining cognitive function, cardiovascular health, bone strength and metabolic activity, decline in their levels can adversely affect the overall wellbeing of a person. People who already suffer from diabetes, obesity, and stress also experience testosterone deficiency. Excessive drinking, smoking and other addictions can also cause a decline in the testosterone levels of the body. You can prevent the decline of these essential hormones if you make some lifestyle and dietary changes. The first step in tackling the problem of low testosterone or estrogen levels, is visiting a doctor and getting tested to find out where your hormone levels are at. If the test confirms that you have low testosterone or estrogen you can easily make dietary and lifestyle changes to boost their levels. Several supplements are available in the market that can address the problem of low estrogen or testosterone. By boosting the correct hormone, you can experience a better physical, mental and sexual function. Just stay consistent with the supplements and keep yourself fit by exercising regularly and eating a balanced diet.
