How does recreation at sea affect our physical and mental health?
Vitamin DVitamin D is one of the essential vitamins for our body. It originates from solar radiation and in a sunny country like Israel you do not have to invest a lot of energy in its absorption, especially if you are on the beach. Such an important vitamin has a wide range of functions in our body especially when it comes to building bone, strengthening the skeleton and maintaining a constant level of calcium in the blood. Vitamin D deficiency increases the risk of osteoporosis and the appearance of bone fractures and therefore it is of great importance especially among women towards menopause.


In addition, it has an effect on the proper functioning of the immune system and it lowers the risk of developing upper respiratory tract diseases. There are also studies that suggest a link between vitamin D deficiency and an increased risk of cancer.

However, do not overdo it. It is important to maintain controlled sun exposure. It is better not to go to the sea in the afternoon when there is peak radiation and in addition you should use protective equipment such as a hat, multiple drinks and sunscreen.


There is nothing like a refreshing swim in cool water when outside temperatures are on the rise. Swimming is considered one of the most enjoyable and health-recommended sports for all ages. Swimming contributes to strengthening a large number of muscle groups in the body ranging from the muscles of the back, abdomen, legs and arms and contributes to their flexibility and improved range of motion. Also, swimming helps the flexibility of the joints in the body and maintains their stability. Swimming is an aerobic activity and therefore effective in improving cardio-pulmonary endurance, strengthening the respiratory system and even helping with moderate weight loss. If you still do not like salt water, even playing with sticks on the beach can greatly improve your physical fitness.

The sea has many minerals (magnesium, sodium, chloride, iodine and more) many of which are good for treating skin problems like eczema and psoriasis. Although the Mediterranean Sea is slightly less salty than the Dead Sea, the health benefits of salt are still preserved. Thanks to the antiseptic properties, seawater can also contribute to the healing of skin wounds, the destruction of bacteria and fungi and prevent the effects of dry skin.

The sand of the beach also has many benefits. The friction with the sand creates a kind of natural exfoliation in the skin that blends well with the sun that opens the pores. Cosmetics straight from nature. However, it is important to be careful not to enter the salty sea with open wounds so as not to create unnecessary infections. Studies suggest that walking on the sand is good for health. The friction with the sand stimulates the nerves, improves posture, allows protection of the joints and knees and releases the feeling of stiffness caused to our body from sitting for long hours in the office.

Unfortunately the Mediterranean Sea like other water sources around the world suffers from pollution resulting from the operation of gas rigs and industrial operators that sometimes discharge sewage into it in an uncontrolled manner. Therefore, it is recommended to get to the sea in the early morning or in the afternoon, in the hours when the pollutants are not active. It is also recommended to be vigilant and check if there are any warnings of pollution where we want to go.

Meditation with waves

Blue eyes, sand, waves and reading ‘Hello Popsicle’ are a sure recipe for improving mood. Instead of spending time in front of the screens, walking to the sea is a great opportunity to change the atmosphere, breathe fresh air and do some joint exercise.
Studies conducted in the field indicate that the sea inspires peace, contributes to mental health, causes an increase in vitality and prevents depression. The noise of the waves and the sun’s reduces stress and contributes to lowering stress just like in meditation treatments.
