Как тишина влияет на мозг

По данным некоторых исследований, пребывание в тишине в течение дня способствует раскрытию потенциала человека: активизирует память, помогает анализировать информацию и даже стимулирует рост клеток мозга.

Громкие звуки плохо влияют на мозг и тело. Исследования показывают, что шумовое загрязнение приводит к повышению артериального давления, нарушению сна и провоцирует болезни сердца. Изучая долгосрочное влияние шума, учёные попутно выяснили, как сказывается на организме его отсутствие.

Дэниел Гросс (Daniel A. Gross) из издания Nautilus подробно описалDaniel A. Gross. This Is Your Brain on Silence. положительное воздействие тишины на мозг человека. Он собрал несколько исследований, где изучалось влияние музыки, белого шума и других звуков, в которых были получены интересные результаты.

Вот три главных преимущества тишины.

Рост новых клеток мозга

Подвергая группы мышей воздействию различных шумов, регенеративный биолог Имке Кирсте (Imke Kirste) из Университета Дьюка планировала использовать тишину в качестве контрольного фактора.

Но выяснилось, что, когда мыши проводили по два часа в день в тишине, у них появлялись новые клетки в гиппокампе. Эта часть мозга участвует в формировании эмоций и переходе информации из кратковременной памяти в долговременную.

Мы обнаружили, что тишина действительно помогает новообразованным клеткам интегрироваться в систему, преобразуясь в нейроны.

Активизация памяти

Даже когда вокруг ни звука, наш мозг чрезвычайно восприимчив. Например, вы слушаете свою любимую песню и она внезапно обрывается. Если вы хорошо знаете мелодию и слова, то она продолжит играть у вас в голове.

Извлекая из памяти знакомые аккорды и текст, мозг создаёт иллюзию звучания. На страницах Nautilus это объясняется тем, что слуховая кора головного мозга продолжает напряжённо работать. Даже если в ваши уши не поступает никаких звуков, мозг всегда найдёт способ оставаться активным.

Стимулирование рефлексии

Когда мозг не сталкивается с внешними раздражителями, он перестаёт фокусироваться и переходит в «режим сортировки». Это не значит, что он полностью отключается. Наоборот. Находясь в состоянии покоя, мозг собирает и обрабатывает информацию. Это называется рефлексией.

Внешние звуковые возбудители заставляют мозг слушать. Если вокруг тихо, наш мозг вынужден прислушиваться к тому, что происходит внутри нас.
