Summer Fatigue – Causes and Tips

fatigue during a particular season is often associated with winter. At this time it is darker, the body is producing the sleep hormone melatonin in large quantities and it is obvious that you will feel much more tired.

Summer, on the other hand, stands for limitless energy. Finally the days are longer again and the warm temperatures invite you to spend the evenings with friends on the terrace. Do you not feel addressed by this and the summer seems to be more of a burden for you?

If you feel tired in summer , you should consider the following causes and tips in order to be able to enjoy the warm season again. Then you will no longer feel tired and will deal better with the heat.

Summer with its hot temperatures and long days is not a joyous phenomenon for everyone. It can lead to stress, which makes you feel tired and listless. What reasons could there be for this?


In summer, your body should actually function perfectly. While it is difficult to get enough vitamin D in winter, this deficit is seldom present in summer. Even if you only spend a short time outdoors, you will get enough sunlight to produce the important vitamin D.

However, it can happen that your immune system suffers in summer. This can mainly be attributed to the weather . Fluctuating temperatures and extreme weather conditions are difficult for weather-sensitive people to endure. If the weather was inconsistent, your health could suffer, making you feel weak and tired.


If the thermometer climbs to highs, your body is busy maintaining the ideal temperature. If you overheat, there is a risk of heat stroke , which in extreme cases can be fatal.

To cool the body, you excrete the sweat more intensely. The sweat not only provides cooling. At the same time, you lose important electrolytes and salt , which you need particularly urgently in summer.

If you don’t drink enough and make up for the loss, your electrolyte balance gets out of whack . As a result, summer fatigue could occur.


In warmer regions it has become established that a longer siesta is held at lunchtime . The heat represents too much stress for physical or mentally demanding activities to be carried out.

Our body only functions well within a certain temperature range. If it gets too warm, he prescribes a break for himself. Therefore, the warmth is often subconsciously associated with less exertion. If it is extremely warm in summer, you prefer to take it a little easier and try to take it easy in order to cope better with the heat.


To deal with the hot temperatures , the blood vessels enlarge. In this way they are better able to give off the heat and prevent the body from heating up.

If your blood pressure is in the lower range anyway, the summer conditions could make you feel tired. Low blood pressure means that the brain is not supplied with sufficient oxygen , which is why its performance is limited . Both on a mental and physical level, you will perceive these limitations and you will be tired more quickly.


The fact that you feel more tired in summer is mainly due to the hot temperatures. These exceed a level that is comfortable for you and your circulation suffers. Follow the tips listed here to better deal with summer fatigue.


It may be a hackneyed phrase, but drinking is the most important building block for you to cope better with the heat. If you sweat excessively, you will lose a lot of fluids. With water or isotonic drinks you compensate for the loss in order to stabilize the circulation.

We recommend at least 1.5 liters of water in summer. If you feel tired, it can be more.

On the other hand, you should avoid alcoholic beverages. These represent a high level of stress. An alcohol-free beer, however, works wonders to restore the lost minerals to the body .


If you like to enjoy the summer in the beer garden or a hearty barbecue, this will hardly be beneficial for your well-being. The high-fat diet poses a greater challenge to your digestion. If the hot temperatures are already stressing your circulation, the heavy meal could force you to recover from it first. Such exhaustion is particularly inconvenient during the lunch break.

It is better if you reach for light meals . Salads or fruits are ideal to fill the stomach and get a refreshment. To do this, have a more extensive breakfast and take in the energy you need for the day.


Contrary to your own intuition, it is hardly helpful to sleep more and to take it easy when you are tired in summer. Many people benefit from being physically active during the warmer months of the year .

For this you should avoid the midday heat. It is better if you run a short lap in the morning and let the first rays of sun affect you. Then you start the day awake and feeling good.


Summer could tempt you to reduce your sleep . The days are longer and you want to take advantage of this.

If summer fatigue occurs, this is an indication that you are not getting enough sleep . Try to keep to your individual sleep duration even in summer and not build up a deficit.

You should also make sure that it doesn’t get too warm in the bedroom . Ventilate in the morning and evening. Keep the windows closed during the day. You can cool off a bit with a fan . If you live in the attic, only air conditioning could bring the temperatures back to a comfortable level. Try a cooling pillow to better face the hot nights.


If headaches occur in addition to tiredness, this is a clear warning that you are suffering from a deficiency. Try the following minerals and vitamins so that you are well taken care of.


If you eat a vegetarian diet , it will be difficult for you to meet your vitamin B12 requirements. It occurs predominantly in foods of animal origin .

Vitamin B12 is said to have an invigorating effect . If there is a deficiency , you feel more tired and the immune system is weakened. The following foods are rich in vitamin B12:

Dairy products


An iron deficiency also causes summer fatigue . The iron is necessary for the transport of oxygen. Without enough iron, the body and mind are not supplied with sufficient oxygen, so that performance is limited. Iron is also significantly involved in the formation of red blood cells. If you have lost a large amount of blood, it makes sense to ensure that you have an adequate supply of iron.

Iron is found in large amounts in the following foods :

Red muscle meat
egg yolk


For some people, summer is the most beautiful time of the year. Finally there is again the possibility to spend more time in the sun and to enjoy the long days.

However, the hot temperatures also have their downsides . They can put a strain on your health and lead to less energy. To a certain extent, this is normal at temperatures above 30 ° C. If you feel tired for a long time, you should follow the tips presented here.

Drink enough, eat more easily, and do some exercise to combat fatigue. Also pay attention to your sleeping environment and design your bedroom so that it does not get too warm and you get enough sleep.

Since I was a child, I have suffered from a house dust allergy, severely affecting me. I felt the effects both while exercising and while sleeping. Constant sneezing after getting up and difficult breathing were the consequences. The allergy has also developed into asthma, which is still a sporting restriction today.
