There are critical periods in life when our bodies are particularly vulnerable to illness. Suddenly the risk of heart disease, stroke and cancer increases. This thesis is supported by the renowned immunologist Luke O’Neill. Studies prove this.

O’Neill speaks of “risk turning points”. Specifically, he names the following points in time, each of which is associated with special developments in the brain and body:

• With average 32 years the previously “youthful” brain comes into being “Adulthood”. This means that the volume of white matter in the brain is fully developed and the nerve connections between the brain areas are maximally refined. At this point in time, humans can reach their full cognitive potential. The ability to think reaches a peak at the age of 32, the “adult age” of the brain, which then remains at this level for around three decades.
• With about 50 years According to immunologist Luke O’Neill, the body enters the so-called “Sniper Zone” a. From this age onwards, the wear and tear on the body from the previous decades takes its toll and the risk of heart disease, strokes, diabetes and cancer increases significantly.
• Around that 66 years old reaches the brain Phase of “early maturity”. From this age onwards, nerve cell connections in the brain increasingly break down. Scientists suspect that the organ responds by restructuring. The parallel increasing risk of diseases of the cardiovascular system can also be accompanied by an increasing risk of neuronal diseases such as Alzheimer’s or Parkinson’s.
• 83 years mark the beginning of the “older age” of the brain. In this phase, the connections between the brain areas are already significantly reduced and most brain activity takes place in individual regions. However, the data available for research into this phase is still quite sparse, which is why researchers have so far had little knowledge of the exact effects.

Dangerous “Sniper Zone” from 50

According to the immunologist, a particularly critical phase of life begins at around the age of 50. In a radio interview with the Irish broadcaster “RTÉ Radio 1” he warns of the so-called “Sniper’s Alley” – literally translated as “sniper’s alley”. O’Neill describes a phase of age in which the risk of illnesses can suddenly “strike” like a sniper. This means a point in time from which several health risks increase significantly at the same time.

What is crucial, however, is that the risk can be influenced. If you live consciously and keep an eye on your health, you can take countermeasures, explains the expert.

Two influences have a particularly strong influence on the health risk in the sniper zone: aging itself and lifestyle. “Wear and tear takes its toll on the body and organs as we age,” explains O’Neill.

There are also invisible changes. Metabolism slows down. The risk of diabetes increases. “Even if you eat the same diet as you did when you were 20 and maybe exercise the same amount, you’re more likely to gain weight,” explains O’Neill. Those who paid little attention to themselves when they were young often feel the consequences more clearly in the sniper zone.

There are three values ​​you should keep in mind

The following measurements are now becoming more important:

Blood pressure and cholesterol: In addition, you should now keep an eye on your blood pressure and cholesterol levels. “The blood vessels become increasingly stiff with age,” as the immunologist explains, “at the same time, blood pressure naturally increases with age.” This also causes more cholesterol to be deposited in the blood vessels. Deposits can form that narrow or close vessels. This significantly increases the risk of heart attacks and strokes.

O’Neill therefore advises everyone over 50: to have their values ​​checked regularly by a doctor. Blood pressure and cholesterol can initially rise unnoticed. If detected early, they can be easily treated. That’s why it’s important to record the values ​​​​from a doctor and get appropriate advice. Medication can help get both values ​​under control.

Four levers for your health in the sniper zone

In addition to controlling risk levels, O’Neill identifies four key elements you can use to protect yourself.

A balanced diet works at any age. The same applies in and in front of the sniper zone: changes are worthwhile. As O’Neill emphasizes, even at the age of 40 or 50, it’s not too late to change course: “It’s like a reset for your body. With this, as I say, reset to factory settings, you can make up for a lot physically.”

He recommends avoiding highly processed foods and following the Mediterranean diet. Vegetable oils, lots of vegetables and foods rich in fiber are considered particularly beneficial for the heart and metabolism.

Regular exercise is another protective factor in the sniper zone. Just a few minutes a day make a difference. According to O’Neill, the key is to increase your heart rate. Walking quickly to the bus stop or supermarket in everyday life can be enough. Exercise also strengthens the muscles, which break down with age. If you stay active, you stabilize your heart, circulation and metabolism.

Adequate sleep is necessary for regeneration and stress reduction. Metabolic products are removed from the brain during the night. Immunologist O’Neill explains the possible negative consequences: “If you don’t sleep enough, you don’t have enough time for this disposal process.” This in turn increases the risk of neurodegenerative diseases such as Alzheimer’s or Parkinson’s. Especially in the sniper zone, sleep is not a luxury, but a protective mechanism.

4. Reduce stress and maintain social contacts

Chronic stress puts a strain on the cardiovascular system. O’Neill sees social contact as an effective antidote. Friendships and relationships have a stabilizing effect. Even short daily social interactions can help reduce stress. This effect becomes more important with increasing age. Anyone who maintains their social life in the sniper zone also strengthens their health.
