A beach is a landform that has been exposed by erosion from a body of water, such as the ocean or a lake. It is often a popular place for recreation, and it may also serve as a habitat for marine plants and animals. Beaches come in a variety of sizes, shapes and compositions. They are constantly changing as the result of natural processes and abrasion by waves, as well as human activities, such as sand removal.
People who live near beaches tend to have better physical health than those who don’t, and it is not just because they enjoy spending time at the beach for fun. It is believed that the quality of air at the beach is much cleaner than that in urban areas, which has a positive impact on the health of those who visit regularly. Beaches are a haven for relaxation and are known to stimulate the release of serotonin, which is a mood-enhancing chemical. The sound of the crashing waves and the feel of the warm sand on your feet can relax your entire body and help you forget about your worries.
Many people find that the pounding of waves against the beach activates their circulation, helping to improve blood flow and lower heart rate. They can also enjoy a refreshing swim in the clear waters, soaking up some vitamin D and strengthening their muscles. Those who struggle to sleep will often have more restful nights at the beach because of its ability to lull them into a peaceful state with its soothing soundtrack.
The process of beach formation begins with weathering, which is the breaking down of rocks into smaller pieces. These smaller particles are then carried away by rivers and streams to the coast, where they can be deposited and build up along the shoreline. A beach can also be eroded by the action of flowing water, which can wear away the sand and mud. Erosion can occur quickly at certain beaches, but it usually occurs over a longer period of time at others.
Beaches are often divided into zones called horns and embayments, with the horns typically gaining sand (accreting) while the embayments lose it (eroding). The appearance and disappearance of cusps on the beach is another sign of its ephemeral nature.
It’s no wonder that the beach is such a popular getaway for those looking to escape from stressful situations, whether it be work or personal problems. The combination of sunshine and soothing sounds from the waves and surf have been proven to reduce stress and increase happiness levels.
The beach is a great source of vitamin D, which has been linked to an improved immune system and the ability to fight off illnesses such as autoimmune diseases. Those who spend enough time at the beach will receive their daily dose of vitamin D naturally through their skin without needing to take supplements. Spending time at the beach can also help counteract the effects of too much screen time, which is believed to lead to poor vision and back and neck pain in some people.
