When the body consumes caffeine, it is absorbed into the bloodstream from the intestines. From there, caffeine travels to the liver, where it is broken down into compounds that affect the functioning of various organs in the body.

According to the journal Neurochemistry , caffeine primarily works on the brain by blocking the effects of adenosine. Adenosine levels normally increase throughout the day, making us feel tired and sleepy. And caffeine provides a feeling of alertness by blocking the action of adenosine.

Enjoying caffeinated beverages is generally harmless, but you should be mindful of your caffeine intake during hot summer days.

Increased heart rate and blood pressure

Caffeine increases heart rate and blood pressure. In the summer, consuming too much caffeine can put extra stress on the cardiovascular system, leading to discomfort or other health problems.

Impact on sleep quality

Body temperature and room temperature are often higher in the summer, making it difficult to sleep. Additionally, if you consume caffeinated beverages during this time, it will be even more difficult to sleep.

Anxiety and stress

Too much caffeine can cause anxiety and irritability, so if you suffer from anxiety, try to stay away from caffeine to reduce your stress levels.

A study conducted in 2005 found that excessive caffeine consumption can cause mental problems such as anxiety disorders and sleep problems.

Affects the body's ability to regulate temperature

Consuming too much caffeine can disrupt the body's ability to regulate temperature, leading to the risk of heat-related illnesses such as heat exhaustion or heatstroke. Reducing caffeine intake can support the body's natural cooling mechanism.

According to the US Food and Drug Administration (FDA), consuming about 400 milligrams of caffeine per day is unlikely to cause side effects in adults.

To dispel the summer heat, in addition to using caffeine in the right amount, you can also use some refreshing drinks such as fruit juice, lemonade, coconut water or herbal tea.
