Milk is a common beverage consumed worldwide for its nutritional value. It is an excellent source of calcium, and it also contains other vitamins and minerals like vitamin D, potassium, and phosphorus.

Milk is also known to have stress-relieving properties. But how does milk affect stress levels? In this article, we will explore the science behind milk’s stress-relieving benefits.

The Science Behind Milk’s Stress-Relieving Benefits

Milk is known to contain several components that have stress-relieving properties. One such component is tryptophan, an amino acid that is a precursor to serotonin, a neurotransmitter known to regulate mood, appetite, and sleep.

Serotonin is also known to have a calming effect on the brain and the body, which is why it is often referred to as the “feel-good” neurotransmitter.

Studies have shown that consuming foods high in tryptophan, like milk, can increase the levels of serotonin in the brain, leading to a calming effect and a reduction in stress levels.

Additionally, milk also contains a protein called casein, which is known to slow down the absorption of tryptophan in the body, resulting in a prolonged calming effect.

Milk and Cortisol Levels

Cortisol is a hormone known to be released in response to stress. An increase in cortisol levels can lead to several health issues like anxiety, depression, and high blood sugar levels.

Several studies have investigated the effects of consuming milk on cortisol levels.

A study published in the Journal of the International Society of Sports Nutrition investigated the effects of milk consumption on cortisol levels in athletes.

The study found that consuming milk after exercise reduced cortisol levels in the athletes, suggesting that milk consumption could be an effective strategy for reducing stress levels in physically active individuals.

Milk and Blood Pressure

High blood pressure is a common condition that can lead to several health issues like heart disease and stroke. Several studies have investigated the effects of milk consumption on blood pressure levels.

A study published in the Journal of Human Hypertension investigated the effects of milk consumption on blood pressure levels in hypertensive individuals.

The study found that consuming milk for eight weeks significantly reduced blood pressure levels in the hypertensive individuals.

Milk and Insomnia

Insomnia is a sleep disorder that can lead to several health issues like fatigue, depression, and anxiety. Studies have investigated the effects of milk consumption on sleep quality.

A study published in the European Journal of Nutrition investigated the effects of milk consumption on sleep quality in older adults. The study found that consuming milk before bedtime significantly improved sleep quality in the older adults.

Milk and Anxiety

Anxiety is a common mental health condition that can lead to several health issues like depression and heart disease. Studies have investigated the effects of milk consumption on anxiety levels.

A study published in the Journal of Health Psychology investigated the effects of milk consumption on anxiety levels in women.

A study published in the Journal of the American College of Nutrition investigated the effects of milk consumption on inflammation levels in healthy adults.

The study found that consuming milk reduced inflammation levels in the adults, suggesting that milk consumption could reduce the risk of chronic conditions and reduce stress levels.

Conclusion

Milk is a common beverage consumed worldwide for its nutritional value. It is also known to have several stress-relieving benefits.

Studies have shown that milk consumption can reduce cortisol levels, blood pressure levels, anxiety levels, and inflammation levels while improving gut health, cognitive health, and sleep quality. It is important to note that not all individuals may experience the same stress-relieving benefits from milk consumption. If you have a milk allergy or intolerance, it is best to avoid milk consumption.
