What supplements increase the heart rate
WHICH FACTORS CAN AFFECT THE HEART RATE? - HEART RATE INFORMATION - 2021
A human heart beats approximately 45 million times a year, but this can vary based on factors such as age, gender, and physical activity. According to the American Heart Association, a normal heart rate can be anywhere from 50 to 100 beats per minute. However, a resting heart rate below 80 beats per minute is considered optimal. Your heart rate is very variable and can change frequently throughout the day. Here are six main factors that affect heart rate.

When your body temperature changes, so does your heart rate. This is one of the thermoregulatory changes that occurs to prevent the body temperature from increasing or decreasing from 98.6 degrees Farhenheit. The heart rate increases when the body gains heat, e.g. B. in hot climates and during training to dissipate more heat from the body. When the body loses heat, such as in cold weather or a cold shower, the heart rate drops to maintain core temperature.

After you have had a meal, your heart rate will increase to aid digestion. More blood is directed to the gastrointestinal tract to process the food. When larger amounts of food are consumed, the heart rate may increase over a longer period of time compared to a small meal or snack. The heart rate can rise above 100 beats per minute and reach a tachycardic rate due to the effects of eating.

During exercise, your heart rate increases to meet the increased need for oxygen and carbon dioxide removal to and from the muscles. The heart rate can be two to three times higher than the resting heart rate, depending on the intensity and duration of the training. Exercising regularly can lower your resting heart rate and is considered a healthy and beneficial adjustment. Drink water before, during, and after your workout to avoid dehydration. When you are dehydrated, it can increase your heart rate and put more strain on the heart.

As you age, your resting and average daily heart rates do not change significantly. However, your maximum heart rate decreases with age due to the physiological effects of aging such as telomere shortening and associated deconditioning. Your maximum heart rate can be estimated by subtracting your age from 220.

Women have higher heart rates than men while sleeping and waking. The general consensus for this difference is that women are usually smaller than men and need a faster heartbeat to get their metabolism up. Much of the size difference between men and women is due to women having less total muscle mass. Since muscle is responsible for much of the body's metabolism, women's higher heart rates can be a natural balancing mechanism to increase metabolic rate.
Caffeine and other drugs

Caffeine, found in coffee, tea, and soda, is a stimulant that affects the nervous system and increases the heart rate. It mimics the effects of adrenaline, a natural hormone in the body that is responsible for increasing heart rate. Other stimulants like cocaine and ephedrine work in a similar way.
On the other hand, there are special drugs that are used to lower the heart rate, such as beta and calcium channel blockers. Beta blockers work by disrupting the receptors that adrenaline attaches to, reducing the hormonal impact on heart rate. Calcium channel blockers reduce the amount of calcium that gets into the heart muscle. Because calcium is needed for muscles to contract, the heart beats slower when this drug is used.
