If you were born in the summer, this is what we know about you

Astrology may be a matter of belief, but there are scientific studies linking birth season to personality and health conditions.

Your month of birth affects your life

Thousands of people are checking their horoscopes intensively to see what that day, week, month, or even year might hold for them. Don't panic, but your horoscope may have changed recently. While science doesn't put much attention into astrology, this field has uncovered evidence to support the idea that your month of birth or season of birth can actually affect your life. Factors such as what your mother ate during her pregnancy — watermelon in summer or pumpkin in the fall — can play a role and the type of environment she lived in, but science has yet to explain some common traits among people with the same birth season.

You may be big and tall

Your genes are yours, but a study has shown that babies born in the summer months tend to have a higher birth weight than babies born in other seasons. Going out into the world can be difficult, but it's better to be a healthy weight than weak or weak. And the same study that reported this result also determined that those born in the summer months are more likely to be tall – could it be thanks to the extra sunlight?  It's not yet clear why, but science has shown that babies born in June and July show the greatest peak in average height.

Have a stronger internal clock

If you have a dog, have you noticed that he knows when it's time for dinner even without reading the clock?

Have you ever woke up at the same time every day without an alarm? This is known as the internal clock, and research suggests that babies born in the summer tend to have a more powerful internal clock than others. Biological sciences professor Douglas McMahon, graduate student Chris Ciarlieu, postdoctoral fellow Karen Gamble and two students at Vanderbilt University conducted an experiment on mice to test the strength of their internal clocks based on the type of light they grew up in, winter or summer.

The study, later published in the journal Nature Neuroscience, showed that mice born and raised in summer light had more refined internal clocks and more regular behavioral patterns than children of winter mice. In short, the season you were born in can affect your brain.

You have less chance of developing seasonal affective disorder

The winter environment not only affects our internal clock, but can also make us more vulnerable to neuropsychiatric disorders. Seasonal affective disorder is a depression-like disorder, which can sometimes be severe, due to changing weather and lack of daylight. Studies have shown that babies born in summer are less likely to develop seasonal affective disorder compared to winter babies. As with the rat experiment mentioned earlier, the theory is that the type and amount of sunlight that summer provides newborns make them better equipped to handle changes in their environment than winter light.

Have more mood swings

There is no detailed explanation for this phenomenon yet, although a study by the European College of Psychiatry and Neuropharmacology showed that people born in the summer are more prone to mood swings and mood changes than others. The study's lead researcher, assistant professor Xenia Gonda, reported that the season a person is born affects their neural makeup, including dopamine and serotonin levels. These are two brain chemicals that help determine levels of happiness or sadness. Dr. Gonda's research has shown that people born in the summer are more prone to mood swings, which means that there is something about giving birth in the summer that affects the levels of dopamine and serotonin in the brain. But that doesn't mean summer babies are more likely to develop mental disorders like bipolar disorder or schizophrenia later in life, but they can be very nervous in the morning.

Have a sunny look

The same European study that found a link between summer births and mood swings also found something else: summer babies are usually more positive in thinking than others, sometimes to an excessive degree. This can be a good thing or a bad thing. Positivity can make you happier, but overdoing it may make you ignore or minimize potential risks or obstacles in your path.

You can have a higher chance of heart disease and diabetes

Unfortunately, if you are born in the summer, you may be at increased risk of serious medical conditions such as heart disease and diabetes.  But technically, it is not summer that leads to the deterioration of health in these areas, but it is any month in which many crops are not produced. In this case, it's about receiving proper nutrition that makes the difference in how healthy you are. If a newborn is able to get proper nutrition and healthy food during the early stages of life (also known as "harvest months," as the study suggests), they are more likely to be healthy. Babies born in the "lean" months — less abundant times of the year, such as extreme heat or extreme cold — are more likely to develop heart disease and diabetes later in life.
