Several studies reported increases in blood pressure in people who lived in higher latitudes. There is less ultraviolet-B (UVB) light and vitamin D production further from the equator, as latitude increases.
Blood pressure also varies with the seasons. Blood pressure is often higher in winter. The temperature is cooler and vitamin D production is lower. Vitamin D may affect the seasonal changes of blood pressure.
Long-wave UV (UVA) also lowers blood pressure. This occurs because UVA releases nitric oxide from compounds under the skin.
The connection between renin and blood pressure is that the production of renin causes blood pressure to rise. Renin is an enzyme produced by the kidneys. It is a key component of the renin-angiotensin system, a series of processes that raises blood pressure in abnormal situations. The body, for many reasons, can produce too much renin that leads to a state of maintained high blood pressure. This disorder is known as hypertension.
One of the main functions of the kidneys is to maintain proper blood pressure through reabsorbing water and electrolytes, or expelling them as urine. This process is gradual and, in a healthy body at rest, works normally. Yet, if one or a combination of three events occurs, the kidneys need assistance in raising blood pressure quickly. The three triggers are a sudden decrease in blood pressure, a fight or flight response created by the body’s nervous system, and a lack of electrolytes in the blood.
When the kidneys detect one or more of these events, special cells within the kidneys release renin into the bloodstream. The release of renin is the first part of the renin-angiotensin system. Renin has many immediate but short-term effects on the body: increased thirst, decreased urination, constricted capillaries and a faster heart rate. Working together, these changes rapidly increase blood pressure. In this situation, higher renin and blood pressure levels always accompany one another.
Vitamin D is the supplement that regulates renin- high and low. If you supplement D, use D3 5000mg. Take it with food and take it at the same time as fish oil. The two together will accentuate the benefits. If the individual is older and also has osteoporosis, the need for Vitamin D is even greater. If you get a prescription for Vitamin D from the doctor, it will be D2 and usually a 50,000 IU dose taken once a week. The D levels are monitored with a blood test until it comes up to a satisfactory level.
Eating foods that support the kidneys is also recommended every day-
1. Celery- aids the kidneys in proper renin balance
2. Fermented soy- promotes proper renin balance
3. Sea salt- replaces sodium chloride table salt
4. Italian parsley leaf- use this in cooking whenever possible or add to green smoothies
5. Cranberries- cleanse the kidney
6. Eat foods that support the adrenal glands which will directly affect hormones responsible for kidney health
7. Watermelon- cleanse the kidney, eat the seeds or make tea from them
8. Miso Soup- with soy curd, sea salt, seaweed, soy sauce
9. Edamame- supportive to kidneys
10. Cruciferous vegetables like cabbage, cauliflower, Brussels sprouts, watercress and broccoli- all aid in estrogen balance
